But hey, you know what you would be a good start? Drive-thru windows at MacDonalds. Talk about a waste of energy for all the wrong reasons.

Maybe in Canada, but stop lights are used to keep traffic going sounds a little weird. Do you run red lights a lot in Canada?
Ok, so they started

I don't think Hyrdogen is a good idea. As you like to say about batteries, there is a huge cost to the environment to make and refine Hydrogen. And, Hydogen requires very large spherical tanks in your car. And hydrogen doesn't just burn like gas when in an accident. It explodes with incredible force. And besides, Hydrogen requires a whole new delivery infrastructure so cars can "gas up". Why bother, when you can get "gas up" at home with an electric car?

You do know that Hydrogen is made from water right?

This is called Electrolysis, and sure I thought about this too. In fact I did this when I was a little kid. With a couple of test tubes or jars, a plastic bucket, wires and DC current, I could separate the Oxygen and Hydrogen from water, then light the gas on fire for a fun POP of a mini explosion. Sound like the answer, right? Zap water and turn it into fuel. The problem is that it is not efficient enough. It takes alot of energy to separate the H and O from water, and alot of time. http://en.wikipedia.org/wiki/Electrolysis

That's why I want to see more efforts go into it. Make the chemical reaction more efficient and we will have the perfect power plant.

Carbon is not the problem, it makes up 0.041% of our atmosphere , 95% of that is from Volcanos and decomposing plants and stuff. So people in the US are responsible for 13% of the carbon in the atmosphere which 95% is not from Humans, like cars and trucks and stuff and they want to spend trillions to fix it while Solar Panel plants are powered by coal plants
think about that
