I may have found an answer to the gas problem. Need help though!?

Ok what i have done is:

Take a hybrid, or elctric car. Replace the car’s gas tank With 2 tanks

*2x tanks of water with built in heaters and freezers*

When The water will freeze, The energy will escape into the electric battery. This is because the molecules slow down, and the energy goes away. We capture the engery and put it into the battery. This will power the car’s electric engine.
We then heat the water back up to normal stage with the heaters. This will now move the molecules faster to create another source of energy. You will only have to pug in the car at first, then it can pretty much run forever like this!!

My truck has a hard time starting (10 points for best answer)?

My truck, a 1996 5.0L V8 with 81K miles. Has a hard time starting. It started doing it last night. It cranks for about 5 or 6 seconds then it finally starts. Its in nearly Perfect condition and i just recently (about 6K miles ago) had a new distributor cap and rotor, plugs, wires, fuel filter, new exhaust system. I tryed running preminum fuel and a fuel additive thinking water in the fuel an that doesn’t help. Anyone have any ideas?
its a manual trans, 4×4
forgot to add, it recieved a new battery and clutch about 7K miles ago

Are electric cars really the answer to America’s green house gas problem?

Although we may have a problem with the rise of green house gases, are our cars the biggest problem we have as a contributor to that? I feel that the idea of electric cars is a step towards helping our problem, but have we put into consideration a)how much a car of this stamina would cost a consumer b) how much the price of electricity will increase with more people becoming dependent on these cars c) the long term effects that these “new” electric cars will have, not only on our population but on the economy d) repair and maintenance for these vehicles e) the price of production….etc. I’m sure you understand what I’m getting at. Although the economy looks promising, the people who are making it that way are your head haunchos at large firms, not the blue collar workers who have to WORK to make things run smoothly. I feel that no ordinary person would ever feel comfortable enough to purchase a car as one of these “proposed” electric/hydrogen/bio-degradable corn syrup cars.
