Energy Conversion Efficiency
Discussions focus on debating the efficiency of energy conversion processes, particularly thermal and electrical efficiencies in generators, power plants, engines, and heating systems, questioning specific claims like 90% or 40% efficiency and heat losses.

Wouldn't efficiency affect the cost of cooling, given that the excess energy becomes heat?
Would anyone happen to know how efficient this is in terms of the energy in/out ratio? I would guess 30-50%?
What's the efficiency of such generators? Surely you lose 70% of the energy?
Wow, claimed 90% thermodynamic efficiency!
Converting less of the switched energy to heat IS efficiency; there's no difference.
You're missing the engine efficiency. Which is another ~90% efficiency process. That brings it down to be lower than an ice.
Given ~20% efficiency it's almost negligible amount of heat.
I mean, if they're 20% efficient, then shunting the energy would mean they have 4/5ths the energy getting turned into heat, no?
That is because the 90% is heat efficiency, this is for extracting electricity, which is much harder.
The article says it's only 5% less efficient. Not that bad for the tradeoff
