I don't think the future of cars lies in hydrogen technology, or at least thats not how it's looking at the moment.
To get the hydrogen you either run electricity through water or get it from oil. In that most of America is powered by fossil fuel power plants it just means more nonrenewable resources will be used elsewhere. Yes, we can develop nuclear, and we should but too bad we're years behind and it'll never happen because of environmentalists. We could use wind, but its not that efficient and doesn't work if it's windy, and solar is extremely expensive and doesn't work 1/2 the time.
Furthermore hydrogen cars have saftey concerns and storing hydrogen is dangerous and takes a lot of energy because it needs to be compressed.
You seem to be suggesting that we will never have any resources besides that which is nonrenewable. (btw, technically coal and oil are renewable but the enviro extremists will never admit that. It still emits a lot of CO2) You are looking at the present, not the future. If all we considered were the present then everything we are doing is for nothing, which is obviously not true. Progress is being made and we ARE moving forward. I just wish the current discussion about climate change would include data on natural contribution, not simply that from human. So much for a real complete theory but oh well.
As for hydrogen, I suspect it will play a huge part in our future energy needs. One reason being we will have more energy from wind, solar and hydro that can help supply our needs. Nuclear is a very good source as well. Even Greenpeace has endorsed nuclear. Back to HHO gas for a moment, if we produce it from readily available, clean energy it makes a lot of sense. It burns so much more efficiently than gasoline and diesel.
As for storage there are some good ways to store it safely and efficiently. Compressing HHO or H gas is dangerous and liquid storage is dangerous also. Take a look at United Nuclear's HHO storage solution. It is safe and it seems to work. I'm sure there are many solutions out there. One problem is market acceptance.
I think all the current hybrid technology is a total waste of time and resources. The carbon footprint before they get to market is deplorable, replacement parts are expensive and my biggest peave about them is they are a temporary solution, a band-aid solution at best.
In view of the harm hybrids are doing to finding a sustainable solution I think hybrid production should cease and spend the money on research and development of a better solution.
Here's the kicker, Toyota and GM have both said hybrids don't make a lot of sense but they are producing them because they know they can sell them. I feel insulted.
I'm getting bored. Let's start another thread to discuss how ethanol is such a bad idea and how it is helping push us into recession.
I have hope that common sense will prevail over the rash views and policies we currently are enduring.
