What are substitutes for Inverters?I would like to know the alternatives.Wat should worry Inverter business?

What poses threat to Inverter businesses?
Well I’m analyzing the inverter business and I want to look into substitutes which pose threat to the inverter business.

To make myself very clear.
For example the business was chicken industry then mutton,pork,beef and fish could be considered as substitutes..

@krk: u r right uninterrupted power supply is definitely a threat but I am looking into products.

how to instal a portable home gasoline operated backup generator through the main electric feed line?

Are there any machines that will air condition your car without keeping the engine running?

Is there a device that operates off a second battery and perhaps solar power?

Some jobs require sitting in your car when the weather is hot. Normally you wouldn’t want to keep your engine running to keep the air conditioning going.

There is a solar powered device that helps to remove hot air from your auto while it is parked, but this is insufficient to cool a car while someone is sitting in it.

I’ve seen air conditioning units on top of campers. But, I think those depend on an outside power source. Are there any like that which can run on solar power and a second battery?
How do I look this up in search engines? Any ideas?

how do I solar power my camper site?

I have property in a very rural area with no utilities close by and would like to know how many solar panels,batteries, charge controler, anf power inverter, would be needed to make a stand alone power system that would run my entire camper?

Can antimatter be used to power a rocket?

I was watching a special on the history channel on rockets, and they brought up a very interesting point. Could we use antimatter to make routine trips to deep space and the rest of the solar system? How could we contain the antimatter blast to the point where it wouldnt blow up the entire rocket?
Would it be a poor idea if humans could actually harness antimatter? I mean…would it create a new cold war? 😛

Will Renewable Energy Be a Sufficient Energy Source for the Future?

Hi there.
I have been tasked to write an essay on, and eventually answering, the question “will renewable energy be a sufficient energy source for the future?”. I have some ideas on where to start and things I should write about, but I was curious to know from others some of the important and valid points I should include in my essay, such as arguments for and against the use of renewable energy, types of renewable energy and their pros and cons, the use of non-renewable energy sources and their pros and cons, etc.
I would also like some help on how I should structure the essay, which is an important part I always struggle with. Basically I’m free for help and ideas, so if you have anything to offer – any knowledge on this subject you could give, I’ll happily accept it.

Thank you. 🙂

Why do wind turbines have the generator at the top?

Wouldn’t it be cheaper and easier to maintenance a wind turbine if the generator was at the bottom? Using helicopters to maintenance turbines has got to be more expensive than a truck. All it would need for the thing to work with the generator at the bottom is a large pole, connected to the windmill by a set of two gears. The way old grain mills used to work.

The use of solar panel in fishing vessel?

I am currently writing a research about this stuff. “The use of solar panel in fishing vessel” Do you know any website or an idea of your own that might be helpful?? How is this being done?

are there any real downsides to pursuing alternative energy?

I mean lets presume climate change is dramatically less significant than predicted. Surely even in this case we would be better off using wind and solar, due to factors such as general pollution. Let the ranting commence…
ps: I know there’s the thing with storing energy for peak periods – so lets presume we continue to develop new battery techhnology etc.
meh there’s a lot of crap here so far.

why cant we use radiation from the sun,stars,and other forms of atomic particles for energy in space?

While in space why not use atomic particles for energy?Energy emitted from the sun,stars,distant galaxies and other places in the universe.Most all particles from space contain radiation that can be turned into an energy to power space ships,space stations and anything usable in space.

what is solar power plants and how they work?

can you give the source where i can read more information about it?

I am a technician. How do I install a set of solar electric system?

The isue is that we bought a set of (10 KVA) of the system and I am called upon to mount it as a prominent technician of the town. So how do I go about all the appropriate dimentions, earth connections, and other aspects like the use of salt, chakol. I am already conversant with the working principles of all the parts. I need a comprehensive explanation of the installation from the begining to it’s end.

I have a 110 volt refrigerator that I would like to power with a solar panel or wind generator.?

It is a full-size model made in 1995. I can not find the watts usage but it is 60 hz and 6.5 amps at full load. I need to know what size inverter, how many deep cell batteries, and how much 12 volt power I would need to put back into the batteries to keep them charged. Thank y’all.

how energy independent could one be if they were to dedicate a 40x10ft.houseboat deck to solar cells?

what might be the weight of the necessary batteries and how cost benificial would this realy be?

How can I calculate how fast a solar battery toy car can move?

For a science project I have been given two solar cells, one of 1 V and 0,4 A and another of 2V and 0,55 A. We are two use these solar cells (and other material) to build a toy car.
We also need to calculate how fast this car will move and I don’t have a clue where to start.Is there anyone out there that can help me how to think? What factors will decide how fast the car will move?

Thanks from

How did the cycling of solar energy through the biosphere begin?

Photosynthesis and cellular respiration are the same chemical reactions headed in opposite directions. Photosynthesis takes carbon dioxide and water and produces carbohydrates and oxygen. Cellular respiration takes carbohydrates and oxygen and produces carbon dioxide and water. Respiration is the exothermic reaction. Photosynthesis requires the input of energy from the sun in order to proceed. In the economy of ecology, why are both reactions necessary? How did the cycling of solar energy through the biosphere begin? How can it be best maintained today?

–Please help me understand this alittle better.

What is Geothermal energy and how does it power Australia?

Geothermal energy is a type thermal energy generated from the Earth. It’s also a form of clean and sustainable energy compared to various of other forms of energy; alternatively, it’s another form of renewable energy. Australia can thus greatly benefit from geothermal energy, due to fact that it has numerous advantages.

Geothermal energy is generated from radioactive decay of minerals within the core of the Earth, and from solar energy absorbed by the Earth. It is evident that resources of geothermal energy comes from miles underground or perhaps even deeper, amongst extreme high temperatures of molten rocks and magma. At the core of the Earth, temperatures may reach over 5000 degrees celsius (9,000 degrees Fahrenheit). Heat are withdrawn and will be generated as electricity.

Geothermal energy is low on cost, reliable and environmentally friendly, and thus geothermal energy is sustainable to our environment. It is considered sustainable because heat extract is spontaneously small compared to Earth’s contents, therefore it doesn’t not affect Earth itself.

Advantages of Geothermal Energy:
There are a wide range of advantages of harnessing geothermal energy. The main advantage of harness geothermal energy is the concept of generating less pollution. Geothermal energy have the potential to reduce reliance on fossil fuel. With skyrocketing prices of petrol, various countries are pushing companies to adopt these clean sources of energy. Geothermal energy can also be used directly and instantaneously, it is evident that people have been using this source of energy for taking bath, heating homes, preparing food and nowadays it is also used for direct heating of homes and offices. There is evidence suggest that geothermal energy also gives a significant cost saving on the economy; geothermal energy generally involves lowering running costs since it saves an amazing amount of 80% costs over fossil fuels. Furthermore, no fuel will be required to generate the power to run the Geothermal energy facilities.

How does geothermal electric plants generate electricity?
Gas that are emitted by geothermal energy is used to turn the blades of a turbine, which then is used to power a generator and produce electricity. It is evident that this process heat energy is converted into mechanical energy, and mechanical energy into electricity.

How can geothermal energy power Australia?
Geothermal energy is rarely used in Australia, nevertheless it’s gradually increasing. There are known potential locations near the center of Australia that have been indicated to contain hot granites at depth which hold optimistic potential for development of geothermal energy. Exploratory geothermal wells have been drilled for experiments for presence of high temperature geothermal reservoir rocks and such hot granites were detected. Above all, geothermal energy productions will eventuate in the upcoming years and explorations are expected to find new locations.

Above all, geothermal energy have the potential is light up Australia with it’s environmentally friendly advantages. We should definitely consider geothermal energy and utilise such renewable energy efficiently.

Should the brightest mind in the world be focusing on solving the pollution problems?

With all the health issue’s tied to smog and the eviromental impact from smog, Shouldn’t we be making this the highest priority to fix? Many of you may not know about the seriousness of the pollution from coal burning plants and we have solutions to fix it but it is moving slow also the burning of petroleum fuels should be fazed out the sooner the better because they just can’t be made clean. All this pollution ends up in the ditches then streams then rivers and lakes and it doesn’t have to be that way. If we have the solutions then why not move on to the future and live in a cleaner world?

Where can I find a Solar energy in electronics workshop based in Colorado?

Where does energy come from in the state of Hawaii?

90% of the houses in Iceland use geothermal energy only. Why doesn’t Hawaii invest more in geothermal energy usage? How come solar and wind power haven’t caught on in Hawaii either?

Why are “Molten Salts” a good solar energy storage media?

I want to use Molten Salts to transfer solar heat from a parabolic dish to a storage tank, then to a stirling engine driving an electric generator. Please provide details on how to transfer the salt/heat in this scenario. Thanks.
Thanks for the links, that’s where I got the idea in the first place. My question is how to transfer the heat from the collector to the storage tank, and if convective heat transfer is enough to keep the storage tank charged. I’ve read that pumps are needed, but how can you pump a 1000 degree molten liquid? What kind of piping/pumps are needed?

generator set manufacture in india near pune can be used in govt. department in emergency for lights

Don’t you think that India has a lot of lessons to learn from recent fearful Japanese experiene?

Earthquake, tsunami and a nuclear emergency, what has happened in Japan is extremely sad. My thoughts are with the people of Japan. The crisis at Fukushima continues to be a race against time, and is clearly not under control.

But Maharashtra committed to set up a nuclear power plant at Jaitapur! The nuclear reactors planned in the country, especially in Jaitapur, Maharashtra needs to be reviewed. It is also an earthquake prone zone, which the authorities are trying to downplay.

When Japan with its advanced technology is struggling with the situation, imagine what could happen in India? (recall the horrid impact of Bhopal toxic gas leak, due to lax safety systems to protect staff and public, that resulted in the biggest industrial tragedy of our times)!

Nuclear energy is a gamble and the risks can be deadly. The Government needs to invest in renewable energy and energy efficiency, that is not only environmentally sound but also affordable and reliable.

The government needs to know that people all across the country support those opposing the nuclear plant in Jaitapur.

People in Jaitapur don’t want this nuclear plant. Green Peace India is taking a signature campaign in the cause against nuclear installations in general and in the Maharashtra site in particular.

Also be informed:
Nuclear power could cost trillions over renewables Scientific American, June 19, 2009:
The analysis factors in studies from Wall Street and independent energy analysts estimating the efficiency of renewable energy at 6 cents per kilowatt hour versus 12 to 20 cents per kilowatt hour for nuclear. Cooper says those costs will fall on either ratepayers through higher electric bills or on taxpayers through large subsidies.

How do you build a thermoelectric generator?

I am doing a project probably going to use solar power to see how much it can power or use waste heat in a home… does anyone know how to build one?

What reasonable steps can I take to better improve my household to be more environmentally friendly?

So far I:

– Recycle all glass bottles and jars
– Recycle all paper from home (and work!)
– Recycle Plastic bottles
– Take clothes to charity shop rather than chuck in landfill.

I am keen to both save money and resources by looking at alternative fuels, but I live in a tiny terraced house with a small garden so a wind-based generator and solar panels may be out of the question! Can I also make my car more environmentally friendly, as it is a petrol gulping 1990 ford escort!

Energy Conservation: How do I start solar powering my home? and living OFF the grid?

Average middle income family living in the boondocks. Where do I learn more about how to do it? Can I do it in stages? How many do I need for my size house? Do I have to put solar panels on my roof? or a big solar panel form in my yard? Are they strong enough to survive severe storms and hail?

What is preventing us from turning to the Sun for our main source of energy?

The Sun is going to keep shining for a long time, and it’s energy is renewable (I think), unlike gasoline and other resources. It seems like the most sensible source of energy to use (or is it? If not, point it out in your answer)! However, it also seems that there are things preventing us from using the Sun. What are they? Is it just too expensive? Is our society too used to using gasoline and other fuels that nobody is willing to take a leap to create a product using the Sun’s energy because they fear losing money? Is it just the lack of technology? and if so, why aren’t we developing the technology to use the sunlight? Do we get a small amount of energy from the sun that isn’t worth harvesting?

What is preventing us from turning to the Sun for our main source of energy?
Regarding the answers that point out something about the Sun not shining 24/7, or that the weather (clouds, haze, fog, etc.) would cause the energy source to be unreliable, why can’t we create something that collects and stores the sunlight into some sort of battery to be used when sunlight is not available?

What would damage liberals more: electing a pretty liberal Republican, or a super far left Democrat?

McCain bought into the whole Global Warming and ANWAR BS, and he is their greatest ally on Illegal Immigration. I even saw him at a photo op with another liberal Republican (Schwartzenegger) at a solar energy plant. With the exception of Iraq, isn’t he going to give them everything they want, and the Republicans are going to be blamed for the mess in 4 years when our country is overflowing with illegals and gas is 5 bucks a gallon because we can’t even pump our own damn oil?

How can you travel through the Sun ?

I have read some online books about heat shielding, the suns temp runs at roughly 15,000,000 degrees Kelvin in the centre. These are estimates as nothing has entered the sun or made it to the centre,
it’s guess work but if it could be traversed perhaps we could learn more from it. What if a vehicle could be built with a large mass of heat shielding to protect it obviosly radiation would be a factor as would heat, distance, pressure etc. I know the facts that we so called “know”, but until you actually go there you can’t study somthing unless your there. They could study mars from miles away in space but they still landed so why not our sun ? Being that if we could harness just the smallest part of that energy we would never need any other form of energy. I am aware of solar energy and nuclear power being that the sun uses two isotopes of hydrogen (tritium and deuterium). Any ideas would be appricated.

What’s an alternative environmentally friendly way of heating up a home?

Good title for research paper about natural disaster preparedness?

I am writing a research paper over natural disaster preparedness, or how people are generally not very prepared at all for a natural disaster.
