Are Hydrogen Fuel Cells a viable alternative to Gasoline?
Every hydrogen fuel cell currently in production or concept uses some form of fossil fuel to generate the hydrogen gas. Are we really saving anything here or are we just covering one problem up with another?
What is the best inexpensive source for light-weight, small wind turbines to generate electricity?
I want to explore the feasibility for using wind power in my particular urban setting where one finds both reliably moderate-to-high wind speeds and a high need for electricity. The general question I need to answer is whether an inexpensive local solution can generate electricity inexpensively enough to compete on cost with electricity generated at […]
What would happen if everybody went solar and wind powered?
Suppose in the near it was commonplace to have nearly everybody’s home and business run on solar power and wind power (Or any other accessible renewable energy resources) What would happen to the economy? Utility services would certainly suffer, possibly to the point of becoming extinct. How would this affect the US and other power-hungry […]
Make electricity with steam at home?
This is probably a silly idea but I really like the idea of making my own electricity. I’ve thought about solar and wind but neither would really work for me. My wife & I will be building a new home in 9-10 years and I have a new idea…. We want to have one of […]
Exelon City Solar Project Far South, Chicago
From Brownfield to Greenfield – Visualizing the Worlds Largest Urban Solar Power Plant. Today, Exelon and SunPower announced plans to develop a 10 megawatt solar power plant in the south side of Chicago- the largest of its kind in an urban setting. Considering this monumental announcement, on Earth Day nonetheless, we decided to create a […]
How does Solar Panels works and what is the cost of getting a solar panel installed.?
I have heard a lot about solar panels and I want to know how these solar panels works and is it really possible to generate electricity using solar panels. And what is the cost of getting a solar panel installed?
Question about Ion propulsion?
NASA’s Deep Space 1 probe used ion propulsion technology to propel it into outer space. Ion propulsion uses an electric charge to ionize atoms such as xenon. These ions are funneled from the exhaust of the craft at such high speends that it is pushed in the opposite direction and propelled into space. The electrical […]
How do solar plants and hydroelectric dams generate electricity?
Can anyone explain to me in a simple way how solar plants and hydroelectric plants generate electricity? I’ve done research, but I’m a little confused. Please note, I am not asking how solar panels work. I want to know how solar PLANTS generate electricity.
What are the advantages of geothermal energy?
I’m doing a project in class on the advantages of geothermal energy, we have to convince everyone else that geothermal energy is the best energy source. I’d like to know anything and everything that is good about it. Thanks!
Human electric hybrid v2
The concept vehicle in the animation is a human-electric hybrid. You power the generator and the electric motor drives the vehicle. You can also drive it as an electric vehicle if you don’t want to or are unable to pedal your self. This is my entry in the Innovate or Die contest www.innovate-or-die.com with just […]
What impact will it have on Africa with the world converting all the “food” into biofuel?
What is going to happen to the poor nations in Africa with the World converting their own surplus maize, soya etc into biofuel? Will this mean that their will not be anymore free “handouts” to the poorer/war and drought stricken nations in Africa by the richer nations? Allready here in South Africa sunflower oil has […]
Solar power runs new technology at Krause
Solar power runs new technology at Krause Karen Harmon is combining the power of the sun to power new technology at Krause Elementary. It is a combination that has worked well as both a teaching theory and practical energy saver. Read more on The Armada Times
Can a ion engine work inside the earth’s atmosphere?
a very small one.
What are some options for electric or hybrid cars?
I was looking for buying a new car and have been wanting to get a new fuel efficient car. Since i drive a lot I will be needing some good fuel efficiency. But with my limited spending I was looking for some government programs and agencies that could help with purchasing a hybrid or electric […]
The Ripple Effect: Increased Demand for Alcohols on Biofuel and Food Staple Prices in America

How will the increased demand for alcohols affect the price for biofuel and food staples in America? There has been concern expressed that the demand for alcohol (ethanol) used is the production of biofuel will result in an increase in the price of food staples in less developed nations. In America, methanol, instead of ethanol, […]
Is there a clean way to extract Hydrogen fuel?
Honda plans to release a Hydrogen fuel cell car in 2008. I know You can extract Hydrogen fuel by “splitting” water with an electric current, but that electricity comes from a power plant, which generates greenhouse gases. Is there a totally clean way to extract Hydrogen fuel?
Water-fuel car unveiled in Japan
Japanese company Genepax presents its eco-friendly car that runs on nothing but water. The car has an energy generator that extracts hydrogen from water that is poured into the car’s tank. The generator then releases electrons that produce electric power to run the car. Genepax, the company that invented the technology, aims to collaborate with […]
Why do wind turbines that generate electricity have only three giant blades.?
I can only guess that wind turbines used to generate electricity have only 3 blades because it is the most efficient design. If this is the most efficient design, then why do house fans have more blades. Why are they not made with 3 blades?
what kind of ship looks better? Wind powered sailing ships or fuel injected steel ships?
I know that steel ships outclass a wooden or wind powered ships but what type of ship looks better?For me it’s the sailing ships.Because they seem so graceful.
