Remember how fossil fuel promoters always say its big advantage over solar and wind energy is reliability?

I can’t say too much, but electricity and petroleum are only temporary energy sources for me. Once waste heat can be turned into usable energy, electricity becomes cyclic. Through energy recovery, electricity can produce fuel, and fuel can be converted back into electricity, forming an energy‑conversion loop. The only drawback is that the system can recover only 98.04% of the energy, which is not what I originally designed. If this were a phone battery, my initial design was that a phone would never need permanent charging again. Now it seems it might need to be charged once every six months or a year. All of this was originally designed for my future long‑term stay on Mars — I never intended to implement it on Earth

Recover 98.04% of waste heat energy? That may follow the 1st Law of Thermodynamics, but it definitely violates the 2nd.
