I'd not that it's criticized, it's just kinda funny that everything comes back to steam engines
Oh for sure. It’s like a desire path or evolution’s crab in that way. I think I just misunderstood people’s criticisms as belittlement of the process without them understanding why it’s still the standard.
Fair enough, I'm sure people DO criticize it but it's mostly a joke.
On a side note, are there any theoretical energy sources that DON'T involve steam? I'm not well-versed
Thermo-electrochemical cycles.
The idea is simple: the favorability of a chemical reaction is a function of temperature, some reactions are more favorable at high temperatures, some at lower. For electrochemical reactions (e.g. batteries) this means a change in voltage at different temperatures. Some reactions have higher voltages, some lower. By choosing a pair of redox reactions such that the direction of charge transfer can be reversed within a specified temperature envelope, one can create a thermal engine that directly converts heat to electrical energy without requiring a turbine.
There's lots of research on this, sometimes called the 'omnivorous' flow battery.
