anyone familiar with the FreeCharge Weza portable power source?

i’m looking for anything that runs on dynamo or human power. i want to disconnect from the grid but solar panels and wind generators ar sooo expensive. all i need to power are a few small appliances. and maybe an electric bike that i’d like to get. thank you; links appreciated
aqualuna, i didnt see this on your site

if you were the last person on earth how would you power things?

if you were the last person on earth how could you power things?
would a portable generator be the best option?
how many things could this power eg could you get 1 big enough to power an entire house and all its appliances?
what type and how much fuel would it require?
would a solar generator be easier?

thnx

How is electricity produced?

describe how electricity or other useful forms of energy may be obtained from 😕

-chemical energy stored in fuels
-water,including energy stored in waves,tides or behind dams
-geothermal resources
-nuclear fission
-heat and light from the sun(solar cell and panels)

thank you so much! guys god bless you all! may all your dreams come true! 🙂

What is the impact of Biomass on the Environment?

I need both the pros and cons of biomass. Any extra information you can give me on biomass in general will be appreciated too.

electrolysis of seawater to form hydrogen from solar energy.what are the pros and cons?

if possible, please explain the pros and cons in detail. if there are cost problems, what exactly would be the cost?
or just write the pros and cons

How much KWH from a wind turbine generator to fully charge two 12V 80AH?

Hi guys,

I am building my own little wind turbine and I would love to know what will be the specifications of the generator that I will use to fully charge two 12V 80AH at the same time. What will be the best way to connect the 2 batteries for a better charge? in series or parallel?

Thank a lot

Sam

What are the best steps one can take to prepare one’s home for a massive solar flare?

The internet is full of bad advice on this topic I think it would be good to be prepared and to do so the correct way. It’s always possible another Carrington event may happen.

What are some developments for solar and wind generators?

I need this information for a science project I am doing and I can’t find any information. Help please?

How much hydrogen (gas and/or liquid) could an oil tanker covered in solar panels produce in a day?

if you take one of those big enormous oil tankers that they have today, and convert it and cover it with solar panels and park it on the equator, how much gas hydrogen could it produce in one reguarl sunny day? and how much liquid hydrogen could it produce?
thanks for the info Ecko, i was really thinking of the feasibility of a hydrogen powered commercial airplane that could travel from LA to Miami. not really cost effective, but green energy is not about making a profit, just being sustainable and beneficial

What Are The Consequences And Benefits Of Solar Power?

Im doing this project on solar power. i need a little help figuring out what some consequences of solar energy. i didn’t think there were any. and if you could throw in some benefits of it too that’d be great. thank you 🙂

Would this be a good way to fight Global Warming at the grassroots level?

Specifically, sending an email to Steven Jobs informing him that you won’t buy any more iPods until he makes a solar powered version available.

Discussion: One of the two obstacles that solar energy has in replacing fossil fuel on a large scale is the high cost and inefficiency of solar PV cells, the devices that convert sunlight (or any light) directly into electricity. It’s going to take somebody with some vision, imagination and most importantly money to make PV cells cheap enough for evey Joe and Mary Sixpack to mount them on their roof and totally disconnect their homes from the fossil fuel power grid. Congress has the money, but since it is essentially split 50-50 these days, any Federal money is going to be spent where the most readily harvestable votes are, namely in farming states where the ethanol boom is already underway.

Its true that iPods only consume a negligible amount of energy, but that would actually make it easier to reach the goal of producing a 99.99% “green” iPod that doesn’t require recharging from an inefficient recharger on the wall thats being energized by a fossil fuel power plant somewhere. Buyers of next generation iPods would be a perfect market for such a device, and once its successful, Microsoft will of course want to play “me too” and compete with Apple in the same market, pushing along the drive to reduce manufacturing costs and increase PV cell performance.

So here’s a chance for the current Disposable Income generation to be at the forefront of the Global Warming fight and with little sacrifice on their part.

what do i need for solar panels to power a 15kw 3phase motor?

i know how many panels but there are things called inverters , are these expensive and can it be done

Is there a portable DVD player than has the option of running on AAA, AA, C, or D size batteries?

In case the power goes out, I have a solar battery charger that can charge AAA, AA, C, D and 9V batteries. So, I’m looking for a portable DVD player that can run on any of these kind of batteries, rather than having to use a generator, or the car’s battery to recharge the unit.

Solar Energy and Hydropower energy would you say these are good energy resources?

Im doing a project for science on energy resources and i happened to chose solar and hydro power energy. I need some opinions about them.. Are these good energy sources..Tell me what you guys think.

Are there any careers that deal with the study of solar energy, generators, ect?

I really like the idea of big solar panels, generators, water powered electricity and such, but I don’t know if there are any good careers out there for it.

How can I explain solar power to 8 year olds?

I am writing on behalf of one of our students, who is really motivated to demonstrate how solar power changes sun energy to electricity to his fellow third graders. He only has a short time for this project so any practical leads help or ideas would be a really big bonus to him. Cam will get a really big kick from reading your responses so thanks in advance for your help!
Hey guys! Thanks SO much for your responses so far. I can’t wait to share them with my student! If you don’t mind I will let him dtermine which wa sthemost helpful answer for him. I appreciate all your efforts. Thanks for oyur time and inspiration!

My physics teacher once asked us to write a paper about energy saving methods our school could apply?

I suggested that we make all the fat kids run on treadmills for at least an hour. It seems reasonable, considering how much stored kinetic energy they have in the form of jiggly flesh. Is this an ethical response?

Are diesel vehicles affected by solar storms?

I have a diesel truck as well as a 25,000 watt diesel standby generator for my home. I’m curious if they will be affected should a solar flare zap us. I’m not too well versed in the whole solar storm issue.

I would like to get some info on a wind turbine to power my home?

I like to know how much it would cost to by a wind turbine to power my home an that includes professional installation. How much on average would i have to pay yearly for maintenance costs. Would i get a task cut from the government. If you can answer my questions that would be helpful. Thanks!

Are infrastructures fueled by renewable energy sources more resilient?

Like if a hurricane happened or some other natural disaster occurred would the variety of the renewable energy sources such as wind and solar bode well for those who depended on them?

Should I get a solar power system or wind turbine to reduce my electrical bill?

I live in west Texas where wind turbines are huge so I am considering either a personal wind turbine or solar system to reduce my electricity bill. The power company says we use 4000kw per month. Which system is best and what model should I consider

How the voyager space probes work in the outside of our solar system and when they will stop their work?

The sun is too far from these spacecrafts. How they abserve the solar energy from the sun?

Do you think the world’s manufactured energy should run exclusively on renewable resources?

Honestly, I think Florida (and most other places) could run exclusively on solar energy.

And I think that is the direction we are going in for the future.

help in electric car?

ok ive been researching about how to build a electric car and i know how to put every thing together but i cant calculate how much distance or speed i can get from the the parts im gonna buy

im thinking of 12v batteries with more then 100 amps

144v system

and i want like 50 or 60 miles and high way speeds on it

can you recommend me what i will need to get that distance and speed

i don’t wanna spend more then 5K

thnks
what if i connect some in parallel and some in series
Ive seen cars that can get that much range and didn’t cost much

What should i research first before tackling a gas to electric conversion?

i’m getting a part time job so i can save up money for the project. i’m very optemistic about doing this. i’d say i’m pretty mechanicaly inclinded. i’m planning on being a mechanic after highschool.

anyways, what will i have to know about to do this gas to electric conversion? i know the basics already. for example, i know the gas pedal is attached to some device that tells the controller how much electricity to be transfered to the motor.

thanks for your answers!
you can attach a motor to the power steering pump and to the brake vacuum…

plus, who cares about the labour. this is something to do for fun. i’m not a lazy *ss like you who doesn’t want to get up and do something to change the world…
hmmm, that book seems like a good idea. but i looked it up on my local library’s website and they don’t have it…maybe i can get my dad to buy me it. he’s encouraging me to learn this electric car stuff too.
it costs a penny a mile to operate an electric vehicle…what big electricity bill are you talking about? and don’t bother talking about coal electricty being bad for enviornment…i get my electricity from hydro. ye ye niagara falls baby!!!

global warming? does anybody have the common knowledge to see that global warming is natural?

Do you suppose that man made Global Warming? Well, you shouldn’t!
Why?
You don’t have to encompass an elevated thinking ability to see through the propaganda. Here’s how to figure out the truth for yourself:
1. Have you looked at your personal outside thermometer? Records are low and snow storms thrive.
2. Seventh grade physics show that CO2’s molecular mass makes it exceedingly heavy, thus fore; it can’t lift high enough to cause the greenhouse effect.
Yes, there is a greenhouse effect, except it’s mostly caused by water vapor! H2O is, to a great extent, lighter than CO2.
3. University freshman statistics will show you that the miscalculation rate in temperature samples used is greater than the claimed temperature increase.
4. Glaciers in Greenland have recently been shown to be getting thicker, not thinner. Same with Antarctic ice, which is never mentioned by warming alarmists.
5. The stories of polar bears declining are deceit, according to our government’s own statistics.
6. CO2 is plant food! When the earth was adolescent, there was awfully diminutive oxygen. It was lethal to the minority life forms here (primeval micro-organisms as well as plants). It amplified to today’s levels partially as exhaust from vegetation and, to a magnitude, from a few “visiting” comets
7. Reimbursement of forests happens only where government owns the forest. Clandestine tenure of forests results in recurring growing and cutting. They don’t waste the economic assessment of their own land! Take a glance toward the massive forests in Georgia and Florida, owned by Weyerhaeuser & other lumber companies.
8. Sunspot activity is in a cycle in which it reduces warming radiation from the sun. This is essentially causing a cooling cycle.
9. What about recent record cold temperatures and snow storms?
10. Why is it that the big scares always mean big profits for companies connected to governments? E.g. GE owns NBC, which is scaring us. But GE makes big dollars from sales of generators, nuclear, windmills and solar to governments.
11. Those who want US to completely change our lives are immune. Think this, How about Al Gore making his millions – driving his SUVs, owning several energy inefficient HOMES, that’s plural. He tells us to stop using gas, while he is private-jetting around to give big money speeches?
12. We’re supposed to forget similar false fears. Many of the same companies made big money off the “ozone layer” scam. Remember that one? It has also proven false. But, the media which scared us about it has remained silent. Instead, they come up with a new scary theory.
13. About 7 years ago, the same government-connected scientists and insiders were trying to scare us with the coming ice age. Remember that?
14. Volcanoes and the ocean are by FAR larger sources of CO2 and other “greenhouse” gases. Many, many, many multiples of the amounts we exhaust.
15. NASA was actually caught faking “warming” data. They simply copied September temperatures and submitted the same figures for October. They then claimed October was the hottest it’s been in decades.
ok kid. first answerer, your an idoitic hippie arent you? People are not responsible for Climate change we produce 1/10th of 1% of Greenhouse gasses.
Who is at fault Its called the sun and earth….
We have gone through several ice ages and warming periods.
Al Gore is the greatest con artist and makes a fortune off of these carbon credits his companies sell. This Global warming lie he has created. You notice it’s no longer called Global warming but Global Climate change since it has been cooling over the last 20 years. But global warming ended 10 years ago at the peak of the last solar cycle. And it switched to global cooling 3 years ago when the sun shut down all major activity and went into the coolest mode ever scientifically documented. Up until 1998 the world was receiving a slightly above normal amount of power from the sun causing the planet to warm slightly. Since the sun went into standby mode 3 years ago all the planets are cooling off.
Record cold and record snowfall across North Amerca and the world this year. The melting ice we hear so much about from liberals, hippies and other kooks have almost completely refrozen to the original state. After record 11 foot snowfall last year in the northeast and New Year’s snow in Florida this year as part of a record cold year…..once again the global warming idiots are exposed in their hoax.

” According to the US National Climatic Data Center (NCDC), the average temperature of the global land surface in January 2008 was below the 20th century mean (-0.02°F/-0.01°C) for the first time since 1982. Temperatures were also colder than average across large swathes of central Asia, the Middle East, the western US, western Alaska and south-eastern China.
For the contiguous United States, the average temperature was 30.5°F (-0.83°C) for January, which was 0.3°F (0.2°C) below the 20th century mean and the 49th coolest January on record, based on preliminary data’. SUCK IT HIPPIES!!!
kids, just research these facts. they’re all true. “just a mistake”??! come on! its the government!

Got any suggestions, wacky or otherwise, for topping up the battery of electric cars?

You may have heard recently in the news about the governments plan to boost electric car sales by offering subsidies of upto £5K for electric or plug-in cars ( http://news.bbc.co.uk/1/hi/business/8001254.stm ). One of the problems with electric cars is how to top-up the battery without excessive down-time (ie periods where you can’t drive the car). Have you any suggestions, wacky or otherwise, for how to do this?

My own suggestion is to divert some airflow through tubes that run the length of the car (maybe even avoiding the passenger compartment!), with miniature wind-turbines inside that help recharge the battery.
>There wouldn’t be near enough power >generated from that small amount of wind to >make any noticeable difference. Seriously.

Ever tried trying to open the door of your car when it’s traveling at 30mph or more? You might discover that the ‘wind’ is not that small!
>It would require MORE energy to move the car >and you will get less energy from the turbines >due to irreversibility’s.

Irreversibility’s of what?
>You can’t get something for nothing. The car’s motor is what is making the wind you feel. If you put a turbine out the window or in a tube or whatever, you would make less energy than you use to make the wind to turn it with (friction, less than 100% efficiency…).

I agree you can’t get something for nothing. The idea of the tubes would be to take some airflow that would have otherwise been acting to slow the car (through friction of airflow, or drag), and to instead partially convert it to electricity (via the miniature wind-turbines). I wouldn’t stick the wind-turbines out the window!
>How about putting a dynamo into the passenger side window winder. Whilst driving along the passenger can repeatedly wind the window up and down to generate electricity to help top up the batteries. This would also dramatically cut down on friends who wanted to ponce a lift somewhere as well. heeeeheeeheee.

Good idea, but with some minor problems:
Extra drag whilst the window is in the open position.
Your passenger may develop RSI.
Your passenger may develop bigger arm muscles to thump you with!
>can it run on feces?
If you could bear the stench!

how would I go about building a a rear carrier mount bike generator?

I am trying to build a device which would mount on the rear carrier of my 20 inch folding bike, which would generate and store electricity, for anything, within reason that can be plugged in (i.e lamp, computer, stereo etc).
I bike about 10-15 miles a day and I would like to generate some power and $ave on my elecricity bill (I already have solar panels) and create some green power.
So I want to create, in essence, a kinetically generated charger to mount on my bike, which, when I get home, I can plug appliances into.
If such a product already exists where can I get it. If I need to make it from scratch what is my first step?

Does anyone have any ideas for green home insulation which would work on a model for a competition?

but it must be possible and not crazy
by the way they will test it with a beaker of water and see how long each model can keep it warm

Alternative energy jobs – what should I study at university to get one?

I would very much like to work in this field. However, not as an engineer or any technical person, I’d rather work with the sales/management part of the business. I am really enthusiastic about environmental stuff, but Physics is my weaker side. Do you think they would hire me if I studied something like Business Management or International Trade? If necessary, would it be sufficient if I learned the technical stuff as a post grad?

Should the international countries cooperate together to help built the future interplanetary spacecraft?

I think the international community should cooperate together instead of individual competition to help jointing the technology together to help built a more technological spacecraft to explore the unlimited space and funding the project would be a big help from the countries and the New Horizon would be a great example since the New Horizon project almost need to stop because of funding problem. And exploring the space is a human accomplishment so I think the world should cooperate together to help us understand the world around us

Why do so many people bash nuclear energy and radiation when they clearly know very little about it?

Seriously, what’s with all the hate? It seems like everyone thinks that they’re some sort of sophisticated researcher that can prove nuclear energy is bad, when really it’s the best form of energy that we have. It’s miles better then coal, gas,solar and tidal energy. That’s why countries like India and China that need energy our building nuclear plants.

We use nuclear energy for so much other than weapons (which we can use to counter terrorism)
– Powering our growing population. 79% of France’s energy comes from nuclear energy, because it’s relatively cheap and reliable. Other major cities like Toronto, LA , New York, and England are in constant need for more electricity and nuclear power plants aid tremendously.
-Sterilization of materials (killing bacteria) or Irradiation of food
-Medical Imaging, (You know X-Rays, MRI’s etc)
-Radiation Therapy for Cancer patients
-NASA uses nuclear energy to power there various projects and so does the US Navy

I should also add that Nuclear energy does not emit any green house gases! Like I said before, no other form of energy even comes close seeing that nuclear energy is so diverse in its various applications. It can also be safe. I know where I live in Canada we’ve had nuclear reactors since 1971 (40 years!) with no accidents what so ever.

What’s the deal with all the hate?
What happened in Fukushima was “an act of god” (using law terms) and even after the two bombings the Japanese were able to grow crops and raise cattle, life moves on. And what percentage of 3 Mile island, Chernobyl and Fukushima make up of the reactors in the world? There are over 400 commercial plants plus a bunch of research facilities. Without them we wouldn’t have all these good uses. I personally feel that media is just trying to push some extremely perverse agenda

Toxic Waste is an issue but it isn’t one that has shown any major negative effects on humans.

Any ideas on how to make a movie on Energy or electricity?

I have to make a movies about either Electricity or Energy. I really do not know how to make a movie about one of these. I have 4 other kids to help me. I have to act something out about it. Im 14 so it cant be like little kid things. I also have to have it done in 2 months. Any help?

How is living on yacht compared to a townhouse/condo?

Has anyone lived on a 40 foot +/- yacht? I see them outside my office window all day and it seems like a relaxing life. Are they really too small to live(single) comfortably and how fast do they depreciate? A quick seach revealed that a 40 footer cost more or less the same as a condo or small house, but what are the upsides of living on a boat(other than being mobile)?

How much does 33.4 kWh of electricity cost for an electric car?

I got this info from another yahoo answers question, ‘33.4 kWh of electricity is equal to the energy in a gallon of gasoline’. So how much does that much electric cost?
