Posted May 10, 20177 yr This is something that has drawn my attention. Looks like these guys have taken the first step towards getting this tech to the consumer market , unfortunately I could not see any prices ,, http://www.lightsail.com/opportunity/ Lets hope for the best , the only problem would be , what to do with the BMV
October 20, 20222 yr Ancient thread, but interested people may enjoy this https://www.lowtechmagazine.com/compressed-air/ It's an interesting parlor trick, but until they repeal The 2nd Law of Thermodynamics, it isn't really very energy efficient, and there are engineering & safety issues involved in storing and using that compressed air in traffic.... ...but it's still nice to dream.

When it pops I would not want to be close But it seems like Europe is moving towards towards splitting water and storing the hydrogen gas to be used in fuel cells and also as combustible fuel. The japanese have gas cooled nuclear reactors that are able to produce large quantities of hydrogen as a by-product of operations. Might explain why Toyota is not so keen on BEV and would rather develop fuel cells

August 22, 2024Aug 22 My opinion is that compressed air is good combined with a combustion engine because it could exploit the heat of the exhaust gases. I'm a fan of a futuristic hydrogen combustion engine h2 -> turbogas system(combustion + steam power) -> clean exhaust gases(for a combined compressed air engine)... It'd can be more performing(power, efficiency)/green than fuel cells...
