Let's burn hydrocarbons

Mechanical work by burning hydrocarbons

I will discuss a few ways to get more of heat from the combustion of hydrocarbons. Taking into account that incineration is bad for the climate would be better to be thrifty.
In ordinary water Rankin cycle waste heat is too much, given the fairly high boiling point of water relative to the cold part – environment - diagram 1.

I will use steam to warm diethyl ether (308K b.p.) to be able to extract mechanical energy from its heat - chart 2.

It will use waste heat from the water cycle to produce mechanical energy. And we will throw a little bit of valuable heat.
I intend also to further decreased waste heat, but diethyl ether exhausts in general ability of nature to close the cycle and will need to use closed cycle as a result of work done.
How to  become a more mechanical energy from the heat from the combustion of hydrocarbons will discuss in the next post.
