Liquid Air Engine

but many inventors get offered lucrative research grants if they come up with something worthwhile in their live,

Just a great story and political friends will do to get millions,

Ballard Power has been given multi millions over the decades for fuel cells , so far nothing but a great story.

 

Propane, NOT Liquid Air

I have not posted in months, simply because I cannot find a way to express my thoughts any better.
The last description of a system that makes use of absorbed heat and gas flow due to pressure build-up, should be (with some mental effort) clear, assuming one understands the mechanics of expanders and generators.

If one considers the boiling of water, low heat.....slow boil, high heat....rapid boil, turn the heat off....no boil.
To turn the heat off in regard to propane it has to be colder than....-44 degrees.

I cannot say more, as it seems to rile peoples feelings as much as I get irrated when the statement " you have to consider the cost of producing the propane" the cost of production has NOTHING to do with future use (unless it is lost out of the system).

With all that has been posted, it is there, if none can see the mechanics then it will be forgotten.
With that said, I will leave the posting about energy efficiency alone.

Thanks to all that took time to post.
