Mark is right; all of these are possibilities but will they really help that much?
I say the best idea up there is biomass.
If you harvest a crop for biomass, say on a yearly basis, the crop will take carbon dioxide out of the air, and when burned, will return it to the air. There will be no increase in green house gases/carbon dioxide.

HI,

Whereas the other alternative energy sources are well known in general, the compressed air vehicle is really something new for me and really as you say the most tantalizing of all.
I would like to see at least some of the above alternatives taking dominant role in our transportation systems.

Mislim da je ovo sve super,svaka cast svima vama. To su sve dobri ljudi napravili (mozda su vecina cicije teske al nisu zli) . Eto bas vam hvala na ovim divnim izumima. Zivjela umjetnost

The sooner we have an alternative to fossil fuels at a competitive price the better

Thank you for using the “N” word. I think that the possibilities for nuclear power in this day and age are extremely over looked. Misconseptions and fear are two of the only things standing in the way of our country being self sustaining when it comes to power.

So let me get this straight… We want to replace gasoline with water and food-based products? I’m not condoning the continued use of gasoline on a mass scale but people are dying the world over because they don’t have access to clean water and proper food sources. Let’s not kid ourselves, water is our most precious resource. Food probably runs a close second, don’t you think? Let’s not waste these precious resources on something as trivial as cars. Just my two cents….

“Hydrogen electrons”?? WTF

Cheers Mark, that was both squashing and enlightening. It’s important that we all see the real picture and not get sidetracked by the glitz and glamor that the car companies are so clever at. I mean geez the electric car above = pure sexy. It’s just sad that the engineering still isn’t quite there.

Some interesting concepts, but not world saving ones

Compressed air, hydrogen cells and electric cars do not use these things as a fuel, but only a means of storing energy, to create the potential energy held within the vehicles you must expend energy to compress the air, produce the hydrogen by splitting water into hydrogen and oxygen, or charge the batteries from another electrical source, and currently the predominant source of this energy is fossil fuelled power stations, so these vehicles could more accurately be described as coal/gas powered

The “water powered” car is the most ridiculous claim, water by itself cannot be used as a fuel, you can convert water into hydrogen and oxygen by splitting it, and then recombining it to form water again, but the amount of energy you get when combining the two will never exceed the amount you have to put in in the first place to split the water, in a real life system the energy you get back will not even be equal to that which you use to split water into hydrogen and oxygen

So we’re left with the choices of vegetable oil, ethanol or wood pellets, which are all carbon dioxide producing and unsustainable fuel sources

In short, the only way we can sustain our energy consumption is by introducing cleaner sources of electricity, such as modern nuclear power stations to meet basic requirements and renewable sources for additional consumption, and/or reduce our consumption of energy

I’m sure I’ll get plenty of replies denouncing the view of supporting the “N” word but if my comments only spur a few people to look at the true cost of ignoring the problem it’ll be worth it
