Hybrid cars
This may be an old subject that has been hashed before and I just missed it. Anyhow I got to thinking about how a hybrid can be a lot mere efficent than a regular car of the same size, weight and aerodynamic shape. Our only source of energy on the earth is the sun other than possibly nuclear, I don't know what created that. If I understand a hybrid correctly it's only form of energy recovery is from small alternators in the wheel hubs that recover the kinetic energy of the mass of the car while braking, but did'nt energy have to be put into the mass of the car to get it moving in the first place? I also understand that the small gasoline engine shuts off at a stoplight, but isn't almost as much energy consumed by the starter of that engine to restart it? Surely nobody wants a small nuclear reactor in their car, so where does the energy come form to make the hybrid more effecient? Don't get me wrong, we do need to conserve the energy we have stored in the form of oil, we're using it up like a drunken salor. Ethanol is helping out as a renewable source and wind is being used, but they are only making a dent in our growing consumption rate, but at least we've started doing something to strech the oil. I don't want to start any shouting matches over this, I'm just curious about how the hybrid can be much more efficent than what we allready have. Frank.

Hybrid cars
Thanks everyone for the response to my Hybrid Car question. Now you're getting me interested, I'm going to check out those listed by car and driver. I most likely won't buy anything right now, but as in all products where competition is high the products will get better. Not "if" but likely "when" a new discovery in the technology of the hybrids is found and perfected to make them less expensive, such as cheaper, lighter, more efficent batteries, etc.. Just imagine the oil savings possible if even a third of the cars on the road today could have their mileage improved by ten mpg. Someone brought up the subject of using idle farmland to produce soy diesel. Not a lot of those acres are really capable of growing soybeans without tremendous soil losses due to erosion, etc.. Most of that land is best suited to being in grass, which may hold promise as a bio mass energy producer to perhaps replace natural gas in powerplants, who knows? We do need to get real serious about our future energy needs. I do remember my early years without electricity or a telephone, we got along just fine, but I really don't want to go back to the "Good Ole Days" as folks call them, the "Good New Days" are now, lets try to keep them. Frank.
