 GM recently released their new plug-in hybrid, concept car, the Chevrolet Volt. Unlike other hyrid vehicles, the Volt will be pushed along exclusively via an electric motor powered by a next-generation battery pack that is recharged by a small, gasoline powered onboard motor--or plugged into any standard, electricity socket.
There's only one catch to this exciting car, the technology isn't available to make production feasible--and may not be for several more years. "We have a thoroughly studied concept, but further battery development will define the critical path to start of production," said Jon Lauckner, a GM vice president for product development.
That said, the fact that GM is willing to put it's name behind such a product is worth mention. GM has recently been criticized for its abandonment of the EV1 electric car which it produced from 1996 to 2003. GM claims that it learned a lot about electric vehicles from that product and that technology helped in the creation of the Volt. The biggest changes in this new generation of electric/hybrid car will feature small, more powerful batteries that recharge faster, more room for passengers and faster maximum highway speeds.
The Chevy Volt is projected to fun for about 40 miles on electric-only power before the motor kicks in the start recharging, though the gas motor will never actually power the car itself. |

Hydrogen is the most perspective energy source to be used in future probably and thus economics of hydrogen fuel cells is quite an important issue today. This paper targets the above issue and considers the following aspects: opportunity cost factors, supply and demand, role of government and impact on USA taxes concerned with economics of hydrogen fuel cells.

In the eternal search for cheaper fuels, and a way to eliminate the use of fossil fuel from our environment, some clever researchers have come up with a way of making your own biodiesel fuel. But while it is often promoted as something you can "make at home", there are a number of things to consider, first.
