What battery is best for storing wind generated electricity?
I am wanting to have a wind turbine/wind mill for my home to supplement or replace the grid electricity I use. I see that the winds come and go. So I need to store some amount of the electricity that my wind mill makes. What is the best and safest battery I can use? What […]
Is it time to rethink this idea of switching to hydrogen fuel cells?
At 32 times the total operating cost of diesel, it appears that hydrogen fuel cells may not be all they are cracked up to be. http://www.greencarcongress.com/2008/02/transit-agency.html
Why don’t Americans get it about clean energy?
Obama hit the nail on the head. Clean energy is Wind and Solar. Coal, Gas, and Oil must be eleiminated from our energy diet. Hydroelectric power destroys habitat and Nuclear is downright dangerous. Wind and solar are everywhere so this will be no problem. Our future will be secure in cleanliness and safety.

With gas prices still high in this country, a lot of companies are investing in alternative technologies.?
Hybrids, hydrogen fuel cells, ethanol cars, and biodiesel are all being pretty well covered in the media. What do you think about these (or any other) alternatives?
NRC Questions Westinghouse Reactor Design
The Nuclear Regulatory Commission has questions about the a design by Westinghouse for a new reactor. Regulators say the AP1000 doesn’t meet some safety standards. Meanwhile, 14 projects have been put on hold until Westinghouse can prove otherwise. Clean Skies News’ Executive Editor Margaret Ryan has more.
New Study Predicts Yield For Biofuel Jatropha
New Study Predicts Yield For Biofuel Jatropha An article in the current issue of Global Change Biology Bioenergy predicts the yield of the biofuel crop, Jatropha curcas L., for present and future climates.Researchers related reproductive potential with the natural occurrence of Jatropha, with biogeographic modeling and ecological principles. This model allowed them to estimate yield […]
Do Hybrid Vehicle’s Batteries get their charge from the alternator?
With a hybrid vehicle, I know that they are ran off of gasoline engine and also an electric motor. The electric motor receives its power from the hybrid battery. Is this charged from the regular alternator that is on all vehicles?
Will this perpetual motion machine work?
It involves two bodies with different masses in a enviroment where outside forces due to gravity are neglible. The smaller body, spherical in shape, is connected to a flat disc, resembling a compact disc inside the larger body (also spherical) by a small durable rod with mass that does not affect the system adversely. The […]
How can I set my house up for total solar power?
I am looking to find out how to go about setting my house up for total solar power? I live in the South so sun isn’t a big problem for us. I’d really rather be using a sustainable product than keep letting the electric company keep charging me for THEIR gas usage. Exspecially when I […]

Why can’t we replace our coal burning and nuclear power plants with renewable energy sources?
For example we have enough wind power in the United States to replace all of the fossil fuel and nuclear power sources in the United States. Athough wind does not always blow when you need it, it would seem that in a power grid you will always have wind blowing somewhere to put electricity into […]
Help from the real nerds…phd’s?
Here are my choices: phd applied physics…(w/ emphasis in magnetohydronamics/cfd) phd mech. eng….(thermal science w/ cfd) phd applied science & tech…..(renewable energy) I want to work on the next generation of “powerplant” systems ie. new forms of motive transport/propulsion….ion, magentohydronamic, fusion, etc. please help me choose with your opinions
HELP! What are 6-8 advantages and disadvantages of using wind and geothermal energy?
I need 6-8 advantages and disadvantages of using wind and geothermal energy. If you can help me, explain how to generate wind energy. THANK YOU
H2OWeld Alumininum Magnet Wire Brazing with HHO gas
Brazing with Oxyhydrogen Gas (sometimes referred to as Browns Gas). The oxygen-hydrogen gas is obtained by an electrolytic process from OWELD machines. www.h2oweld.com The oxyhydrogen flame quickly sublimates the magnet wire enamel so the metal is properly prepared for brazing. Brazing with Oxyhydrogen Gas provides a consistent flame with temperature up to 6600’F for very […]

Why can’t a car not only use the motion of the wheels,but use the wind resistance also to generate power to a
Could turbines propelled by the wind resistance,and circulair motion of the wheels be used together to keep a charge on a batterie opperated car ?There has to be a way that’s simple to this magnitude that the world havent considered.Why haven’t the government put more incentives for car manufactures to design eco-friendly cars a decade […]
In a hydrogen fuel cell why doesn’t oxygen loose electrons when breaking up in the cathode?
On the anode side the hydrogen breaks and loses electrons but why dont the oxygen molecules do this.
