How do we stop global warming?
How do we decrease or stop global warming when to run windows vista unltimate and directx 10 video cards we need at least 650watts power supply? Whos at fault?
admin answers:
I think the problem is beyond a few cards kiddo.
We must become more conscious of the effects of our actions on the world. Making responsible decisions is what it is all about. In Europe the latest fad is about the size of your footprints on the planet. It is almost a game there it is so popular.
Here are a few really basic common sense ideas for you. Dump your SUV and get a hydrogen run vehicle. Run your dishwasher only when it’s full, replace air-conditioning and furnace air filters regularly, and adjust your thermostat to a little warmer in summer and a little cooler in winter. You can also set your water heater to no higher than 120 degrees (F); it saves money and is safer. Try low-flow shower heads to use less hot water and wash clothes in cold water. Most detergents today clean just as well in cooler temperatures. Use energy efficient light bulbs. Improve your home insulation. And seal up all the cracks. And my favourite, shower with friends. LOL.
Since all of these save electricity, they save not only resources, but also money for you. It just makes sense.
For you fools who deny the truth of global warming, here are a few facts for you. By the way, they also include some solutions to help east the problems, although there is so much more to do. Saying you do not believe in something does not make it any less real!
Big Business is beginning to look at global warming through eyes blinded by dollar signs. Climate change is replacing tech and bio tech as the major investment theme of the future. Wall Street’s analysts are devising ways to cash in on weather.
Discussions have changed to talk of what a 1-degree rise each year in temperature would do to profits. Global warming is becoming a major market-moving force that represents a generational shift likely to influence how people invest for decades. The world’s biggest financial services firms are investing massive amounts of time and brainpower trying to pinpoint what stocks and sectors will benefit or be hurt by Global warming.
There are at least 74 companies in 18 countries that can profit from changing weather patterns. Global warming will change world economy. There is a company in California which manages the largest pension plan in America that has committed $800 M to invest in clean technology. At this time 90% of global warming is the result of human activity.
Temperatures around the globe could raise 2 to 12 degrees Fahrenheit by 2100. This will result in more intense heat waves, stronger tropical storms and a rise in sea levels that will swamp low-lying cities and farmland. When I was boating through rice fields in India last summer I wondered how these people would survive even a few inches rise in water. Most of the farmers live at sea level.
Corn will be used to create ethanol. The technology is already in use. If corn is used to provide even 10% of the nation’s automotive needs, it would use 35% of America’s corn crop.
Since 25% of all food prices are affected by the cost of corn, we could face a corn vs. Food situation. Farm leftovers can be used to create cellulosic ethanol for fuel. Farm equipment companies should do well because farmers will be rethinking harvesting techniques. They will also retool their machines for the new fuels. Monsanto is working on creating more drought resistant crops.
Energy conversion devices and sun power are becoming buzz words. Windmills. Fuel cells. Solar panels. Several companies are developing types of clean solar panels with the hope of rivaling oil and coal, deemed “dirty” fuels. Eco technology is still too mature to make a lot of money. Solar will only create a tenth of the world’s energy. Technology that makes dirty energy sources like coal and oil cleaner. There will be more money made on the dirty stuff. Nuclear power generators are also on the rise. The new nuclear energy is much cleaner and produces no carbon.
Ethanol, hydrogen, clean diesel, bio diesel fuels hold promise for the future. Hybrid cars are the way of the future. The major car manufacturers are working on increased efficiency. Investing in hybrid vehicles and components and batteries etc will be good investments. Automotive builders are striving to outdo each other in these fields. “Smart cars” are popping up everywhere.
The insurance industry will change incredibly. So many energy and utility companies will all have to face different challenges due to the effects of weather. Suddenly they realize climate and profits are closely related. Investors will start to lean more toward green investments. This movement has been spreading for a decade.
I also think security and protection companies might do well because the displacement of people and shortages could result in an increase in crime.
The world’s demand for energy is accelerating as China and India grow. Heavy construction and engineering companies that build power plants will do well. The smart ones will build ecologically sensitive plants will steal market share. They will find ways to make plants more efficient and cleaner. One technology, clean coal, puts devices in smokestacks that pull the carbon out of the exhaust and plow it back into the soil.
After Hurricane Katrina, folks are rethinking the option of coastal real estate. People will develop an aversion to locations on the water and severe-weather-prone areas. People will flee Florida for the Smokey Mountains for example. This covers Georgia, Tennessee and North Carolina. This is already happening. Thousands have begun the process of relocating to higher ground. The high insurance premiums for living near the water will affect property values.
Small parts and components that go into everything from washers and dryers to fighter jets and elevators could play a gigantic factor in curbing energy use. We already have the technology to reduce the world’s power use by 30% overnight. About 11% of the savings could be achieved with efficient electric motors inside washing machines, conveyor belts and other motors that use half the energy of older technology. Another 11% could be saved in transportation using hybrids. The last 8% can be saved with energy-efficient fluorescent bulbs. Currently businesses that focus on energy efficiency are already becoming more profitable.
The wealthier nations are in better condition to deal with these things. It is the poorer nations that will have serious difficulties. Holland could just disappear. A great deal of landmass will also be lost, which will drive up the cost of real estate everywhere.
That is how America sees the future according to Global Warming. In its usual entrepreneurial way, Americans see the silver lining of this problem as an opportunity for positive change and innovative growth. This is all fact, kids. You know corporations do not make such changes without a good reason.
Although global warming is a problem today, there is an equally huge problem that governments do not want their citizens to know about and keep all information suppressed. If this particular topic is not addressed, we will face changes on the planet more deeply embedded not in nature but from within our bodies.
I speak of Depleted uranium and its effects on the human race and all other living things on the planet. If the environment of earth is ill humanity becomes ill. Our health depends upon its health. The environment is the world around us, the air we breathe, the water we drink, the soil in which we grow our foods. It is exciting to see individuals begin to take responsibility for their footsteps upon the planet even if the movement was only taken seriously once Global Warming began to hurt big business. There are all sorts of wonderful initiatives out there.
However, we can pretty things up, cut down on carbons and become more eco friendly but all of these accomplishments will mean nothing if we do not get to the invisible pollutions that are becoming harder and harder to escape. I am not trying to denigrate these wonderful actions people are taking. We have to begin somewhere and global warming is as good a place as anywhere.
N April of 2003, the World Health Organization said they expect global cancer rates to increase 50 percent by the year 2020. Infant mortality is going up at appalling rates all over the world, an indicator of the level of radioactive pollution. Basically, it’s like smoking radioactive crack. It goes straight into the blood stream and is carried all throughout the body into the bones, the bone marrow, and the brain. It goes into the fetus and corrupts its development. It’s a systemic and a radiological poison.
Winds carry this radioactive dust several miles, contaminating the air and water that innocent humans breathe and drink. These munitions were used in both Iraq wars, Kosovo, and training sessions in Puerto Rico. We have huge dust storms that are a million square miles and transport millions of tons of dust and sand every year around the world.
The main centers of these dust storms are the Gobi Desert in China, which is where the Chinese did atmospheric testing, so that’s all contaminated with radiation, and it gets transported right over Japan. It then comes straight across the Pacific and dumps its sand and dust in North America. The stuff is loaded with radioactive isotopes, soot, pesticides, chemicals, pollution — everything is in it — fungi, bacteria, viruses.
The Sahara Desert is another huge dust center, and it goes up all over Europe and straight across the Atlantic, to the Caribbean, and up the East Coast. Of course, you get it in Texas with those hurricanes. They all originate in the Sahara Desert.
The third region is the Western United States, which is where the Nevada test site is located.
Concentration of the depleted uranium particles in the atmosphere all around the globe is increasing. There are indications that the U.S. Will go in June and bomb the heck out of Iran. U.S. Army ammunition factories have very large orders for those huge bunker buster bombs that have 5,000 tons of DU in the warhead.
Hold your politicians accountable. For both this crime against humanity as well as implementing stronger controls on factors contributing to Global warming. Both of these horrible threats must be dealt with immediately if our grandchildren are to have a planet to live on.
IN A TIME OF DECEIT, TELLING THE TRUTH IS AN ACT OF REVOLUTION!
Jenny asks…
Can we use solar energy to power a whole house in india?
admin answers:
It is all relative – Big House, or Small House?
Yes you can use solar energy.
2 types – generate electricity and/or make hot water.
First work out your NEEDS.
Make a list of all the appliances you will be using – at any one time – read the Watt or Kjoul rating off the ‘appliance info plate – at the back’.
Add to this all the LIGHTS – ie… 10x 60 watt globes = 600 watts
Arrive at a TOTAL POWER for the House – and start costing the SOLAR COLLECTORS available to you to find if you can afford it all.
HOT WATER SOLAR is easy – a tank and a BLACK hose – use convection [hot water rises] and place the Tank on the roof – and the hose below it – then you have a gravity feed to your bath, etc.
SUPER HOT SOLAR WATER – can make steam pressure, to run a turbine blade connected to a generator.. But this is a bit more hassle and high tech.. But simple in concept.
ELECTRICAL STORAGE – batteries – is what you charge up of a day, and run them flat of a night – via an INVERTER – to boost the 12volts (DC battery) – up to 115/240v to run your ‘stuff’.
A small solar collector is okay for your mobile phone or computer – maybe… Check the ‘watts’.

I am trying to use solar energy in four wheeler.###Trying to mount solar pannel on carrier of 4 wheeler and providing solar power to a/c,lighting and music system.This has been sent to govt. since one month ,But I hope nobody will take care of it as my experience says.
admin answers:
Our company took one of those 12 volt John Deere Gator toys that kids ride on, and mounted solar panels on the roof, and it would have to sit in the sun two solid days to charge the battery to where the kid could actually drive it.
It’s only a working idea that they take to schools for energy fairs, and it’s only to inspire. So I know if you are looking to actually power a real car, not even a golf cart (NEV) with solar panels hanging off everywhere, you are going to need to find the latest technology and even then there will likely be a lot of shade with panels hanging way over the roof and hood nearly like an airplane to get it to where you could drive on the generation. It kind of sounds like the National Lampoon’s Vacation Family Truckster, ‘If you think it looks bad, just wait until you drive it…’
Ken asks…
What does mechanical and thermal energy have to do with Global Warming?
I am doing a project about the conversion that take place in Global Warming. I need to figure how heat, mechanical energy, and thermal energy is converted.
admin answers:
Global warming is the theory that the earth is warming. There is little accurate data to support this, but historically we are very cold, almost as cold as the ice ages. So, likely we are warming. Anthropomorphic global warming is theory that man’s activities contribute significantly or mostly to global warming. No evidence for that, but many people fervently believe in it anyway.
Not clear what energy conversion you are talking about. Energy can have different forms. Two basic catagories are potential energy and kinetic energy. Potential energy is stored energy that can do work; kinetic energy is energy stored in the motion of an object. Classical examples are kid on a swing or roller coaster. As the kid or coaster reaches the top, speed slows as potenial energy (height of weight) increases, and kinetic energy, sort of like momentum, decreases.
Other distinctions are things like chemical, mechanical, thermal, electrical energy. For example, coal or oil are chemical energy (also potential energy). A moving machine represents mechanical energy.
If you are talking about electrical power generation, this doesn’t have much to do with global warming, but it sounds as if your teacher may think it does.
To make electricity, the most efficient and cheapest was to make it is generally to burn coal. The coal fired plants work by burning the coal to generate heat or thermal energy (same thing). This is used to boil stream inside a huge “tank” called a boiler, and to pressurize the steam to very high pressures and temperatures. This steam goes through a turbine, similar to a big jet engine on an airplane, where it forces the turbine to turn. This is the mechanical energy form. Mechanical energy is nice partly because it is easily converted to electricity. This is done by turning the crank of a generator, which looks pretty much like an electric motor.
Alternative energies can work a little differently. For example, in wind power a propeller (called a wind turbine) is turned by the wine, making mechanical power. This then turns a generator that makes electrical energy. Solar power can use small cells (like a battery) that make a little electricity. Large solar plants use the sun’s heat by focussing in onto a boiler that makes steam and runs it through a turbine to make electricity. Water turbines convert kinetic and potential energy in water to mechanical energy, which again drives generators. This could be considered solar power, since the water gets above the dam via solar energy evaporating it, then rain from the clouds.
Google things like power plants or coal power to get more info.
Good luck.

Your Questions About Solar Generators For The Home
Betty asks…
What’s the simplest way to hook up a small generator to a home’s power grid?
I’ve search the internet extensively and haven’t found an answer to this question.
I just wanted to play with solar panels and human powered generators and couldn’t figure out the simplest and cheapest way to hook it into my house to get some benefit out of it.
I.E. can i just have my panel hooked into a charge controller and a single battery to act as a float and then an inverter and hook the output from the inverter into a standard power plug in the house? can i push power into a power outlet or is there some system so that power can only come out of the plug?
anyone have any ideas on the easiest simplest way to hook up a panel or a car alternator? I was going to turn my indoor bicycle into a generator by hooking up a car alternator to it… how could i most simply hook this into the house?
admin answers:
You can put power into a plug, just be sure to shut your main breaker off first. And shut off breakers for high draw appliances like AC oven microwave waterheater etc.. When my power goes out I unplug my dryer and plug in a whip that I made that plugs into my generator. If you want to power the whole house you will need to use a 240v recept like for an electric dryer, if you use a standard 120v recept you will only power up one bus bar / half your house.
Yes 12v with an inverter will work, yes you can put an inverter on your car battery and power your house with your running car I suggest getting a deep cycle gel type battery in your vehicle if you want to do that, you should also upgrade to a 200a alternator if you’re going with an inverter larger than 2500watts, a car won’t be near as fuel efficient as a standard generator though, and it won’t put out near the wattage. But like I said before, if it’s only a 120v inverter you’re only going to power up half the house
Lizzie asks…
Who makes the parts for a wood fired steam powered electricity generator that can also heat a home?
Outdoor wood and coal furnaces as add on units to heat pumps are becoming popular now. I’m trying to find a vendor who makes a stand alone unit for powering a riverside cabin home. A 200 amp 240 VAC unit would be perfect, but a 100-150 amp unit would power everything.
admin answers:
Wood and coal good for heating and cooling but using them to produce steam to power a small generator would be too costly. Hippies run 200 amp services using solar panel arrays for lights and fans to move the hot and cold air.

Lisa asks…
Which is the best DIY solar panel/wind turbine program? Real people only, please.?
I’ve been looking at all of the options for installing solar electricity systems online, and I’ve noticed that even the so-called review sites all seem to be part of a sales pitch….haven’t found a single, independent review of any of these products. Has anyone out there actually used any of these (Earth4Energy, HomemadeEnergy, etc.), and if so, how good are they?
admin answers:
If you have noticed that Earth4Energy is a scam (which it is), then you may be amused by my analysis of it at http://www.nlcpr.com/Deceptions6.html
If you want to build a wind turbine yourself (like a good engineer would), then get the following book:
Homebrew Wind Power
A HANDS-ON GUIDE TO HARNESSING THE WIND
Dan Bartmann & Dan Fink
Foreword by Mick Sagrillo
ISBN: 978-0-9819201-0-8
Published by Buckville Publications LLC
You can get this from www.otherpower.com This is a startlingly complete book and it has all the background theory you need too. They explain why, for example, you cant use a car alternator or something from a generator, and then proceed to build alternators from scratch. The references are compete — if you explore them and have the time to read, you will be right up there with the pioneers.
As for DIY solar, you can get the parts (panels, inverters, batteries, charge controllers) individually from many sources and make a system. It will not be cheap. You can’t make your own silicon cells, and probably aren’t up to designing the electronics, can’t make your own batteries etc.
My recommendation is this: Get the wind book. Look through the web sites of some of the better looking solar dealers, and if they seem to be “no bull” then e-mail them and tell them what you want. E.g. An entry level system, 80W panel, battery, inverter and charge controller so that you can make enough power for say, a small laptop. The good ones will be able to tell you what works together.
If you are thinking of a whole home solution, then you have a lot of reading to do. You need to switch to natural gas or propane (no electric heat, electric stove, electric hot water) and absolutely mininize the electrical load.
It would be nice to market a good DIY manual, but with a truthful title like “Generate power at home for more than you are paying now” or “With thirty thousand dollars in equipment, you too can avoid those monthly power bills” sales would be pathetic.
Have fun.
As for “real people” comment, when I see questions like this, I wonder if I am wasting my time because many of the questions are not real either. They are simply created by scammers so that they can add their scam replies and rate it best answer. I find this particilary galling when someone says, “this is for my science fair, and I am 14 years old” and all the answers are Earth4Energy scammers. Other times, I find my comments pasted on fake energy sites with links to pharmaceuticals. It is a mad world out there.

Your Questions About Solar Energy Colorado
Sandra asks…
How do you think the united states should gain energy independence?
I am looking for how people think we should gain energy independence here in the united states and not have to rely on foreign countries for our energy sources.
admin answers:
There is no realistic possibility of it happening in the foreseeable future. Hydrocarbon fuels are essential for transportation, and alternatives to petroleum are simply too expensive to be practical. In future, if nuclear power catches on big, there may be enough nuclear energy available to split water and make hydrogen, which could be combined with coal to make hydrocarbons — but the process is very expensive in terms of energy and won’t be economical any time this century. Oil shales, present in vast quantity in Colorado, will be a cheaper source for decades, although they are not cost effective now. Solar and wind will continue to be bit players, as they are simply too expensive — as well as intermittent.

Jenny asks…
At which height should i be seriously concerned about lightning strikes and how to compensate?
I am building a wind turbine and it is on a steel rod and i will be using a metal pole footed in the ground (4ft as per the local frost line) as its structure.
I have been contemplating on if i need to use a grounding rod to ensure that the generator ($300) or my charge controller/battery bank does not get damaged.
This is a completely homemade project and i plan to have it stand 9-10ft in the air, it is not for major power production but rather just an experiment and i will use the power generated to provide power for garden lighting.
There are trees in the vicinity of where i plan to place the turbine.
admin answers:
Henry, you are on the right track by being concerned about lightning, but there are ways to mitigate the problem. We have a 75 foot metal tower with a turbine on top now. My installer calls our property, “lightning hill.” We had several direct hits the first year or so and damage to our inverter, charger controller and turbine controls, as well as the TV, phone and furnace circuit card. After consulting with a retired radio tower engineer, Xantrex and the electrical inspector, what we learned is that grounding is quite a science.
Your metal post, or tower needs to be earth grounded, but by something better than the bottom 4 feet or so of the post jammed into the ground. Then you want to connect any DC negative if you have batteries, and AC nuetrals to a good ground point as well. The point to grounding the tower is not to attract the lightning, or dissipate it once it hits, the point is to, “de-ionize,” a volume of air travelling over the tower, turbine and wiring. The bigger culprit is static buildup from miles of air rubbing up against the tower building up a charge, much like walking on new carpet with dry shoes, then grabbing a metal door knob. While the spark your hand feels is uncomfortable, it is fatal for the circuit card in your inverter. By constantly, “wicking,” this charge away at the tower base, it doesn’t have a chance to build up and eventually jump across your inverter or charge controller, and better yet, it doesn’t have a chance to build up an ionized air column around the tower, which is what the lightning bolt is looking for in the first place.
In our case, we drove four 8 foot copper ground rods into the earth in an array around the base of the tower, then connected each one to each tower leg and the guy wires with separate bare copper wires. Then the common ground point in our battery room has the chassis frame from all our electronics, the AC nuetral, and the battery DC negative connected together there. After that, we ran a #4 bare copper wire from that point to the top of our steel well casing. Again, we are constantly wicking away static charges, and providing an easy route for a large surge to exit the system as well. We also put surge arrestors on the base of the tower, and incoming lines from the tower and solar array leading into the battery room. It’s been 9 years since then, and after tons of storms up here in the Northern Great Lakes, everything is still humming along nicely. The retired radio tower engineer told us in many instances in areas prone for lightning, such as Florida, they sometimes hired a well company to drill a 200 foot deep well and install a steel casing, but no well pump. Then they would just use the well casing for a ground rod. Think of it as a drain in a bathtub, if it is unplugged, has a large 3 or 4 inch pipe leading out of it, and it is free flowing to the city sewer, than the tub should never overflow. If it has small piping, many kinks and turns, and a partially plugged screen, one day the tub will overflow, you just don’t know when. The well casing is like a really big drain, and the extra electrons keep flowing down it all day and night.
Home Power Magazine ran a side bar article on our systems grounding plan about 10 years ago. If you subscribe, you can look for it on their websites archives under, “Ground Side Bar.” If you don’t subscribe, you should, it’s a great periodical on this materiel and inexpensive. Good luck Henry, and take care, Rudydoo

Your Questions About Solar Energy Generators For Home
Donald asks…
Is there a way that a wind mill can generate enough electricity to turn the lights on in a house?
I am writing an essay for school and it has to be on everyday life and how you can use alternative fossil fuels to do the same things. So if they are other things you can think of that i can use (wind energy, solar energy, hydroelectric energy, etc), to put in my essay that would be extremely helpful. Thanks!
admin answers:
A good way to discuss it would be to think about using Alternative energy to supplement fossil fuel energy. Aside from hydropower, alternative energy is not consistent enough to be used on a small scale to power a home (like if clouds cover your solar panels, you’re screwed).
If you used all kinds of alternative energy and then supplemented with a generator, then you’d have a really good, and consistent source of energy.
Mandy asks…
how car batterie to for solar system of 5kw and how much roughly cost?
i am planing to have independent solar system at home 5 kwh capacity , how many car size batteries do i need for this system.
with thanks for the answer.
admin answers:
Batteries are only 50% efficient at charging and lose 1% per day. If you can, use net metering and just sell your excess power to the utilities and buy the power you need back from them. How many batteries you need depends on your energy usage ( a figure of 5 kwh is meaningless without the period of time that is over ) and how long you want to run without solar power. Most people design just for diurnal use and fill in with a generator for back up power in an off grid home. But it is possible to consult the weather office and determine how many days in a row you can expect to be without productive sunshine and how many days you can expect to be able to recharge your batteries over. Note that the average North American home uses 950 kwh per month.
You also have to take into account that most systems are designed for just the bulk charge to 80% capacity.
If you are saying that you use 5 kwh evenly over a day and you can expect 8 hours of useful sunshine then considering the 50% charging efficiency of lead acid batteries you would be looking at storing 5 kwh * ( 2 * 16 / 24 ) = 6.7 kwh. A typical car battery is 12 V at 65 AH so it would hold 780 WH, at 80% capacity that would mean you would need 10.73 batteries and you would need 2,504 watts to provide for the 1/3 of the 5 kwh that you use when the Sun is out plus the recharging of the batteries, that would be about 25 of those 100 watt two foot by four foot solar panels which sell for about $250 so with a charge controller you would be talking about a $13,000 system. However, this assumes you have DC appliances. If you toss in an inverter, those can be as bad as 65% efficient so you would have to increase everything by about 54%.
Of course, power usage isn’t even though the day so you should characterize your power use better plus 5 kwh per day amounts to 150 kwh per month which is only 1/6th of typical usage so it may be an unrealistic value.
I would strongly advise that you characterize your power use carefully, consider net metering as that would mean you only have the inverter inefficiency to worry about and not the battery inefficiency. If you must go off the grid, consider DC appliances to remove the inverter inefficiency and consider an absorption refrigerator which could run off a propane tank buried in the yard as food storage can not risk possible daily outages, plus you can run a gas stove top off the propane. Gas ovens are a problem as many have glow plugs which consume 300 watts constantly but if you can find one with piezoelectric lighters or one of the old outlawed ones with a pilot light then a gas powered oven becomes possible. You can also run your backup generator off the propane.
