I still don't see the prerogative for bitcoin. Yes, most industrial processes are inefficient and we can and should reclaim lost energy. There are many ways to do this, and many purposes. Charging batteries seems the most reasonable: making the energy stable and portable. Admittedly I don't know much about battery efficiency, so there may be other more efficient uses. Hydroponics lighting? Where "waste energy" is difficult to access and available only in trickles, it's surely very unsuitable for bitcoin mining, which is energy intensive. Frankly, there are far more pressing issues than making more bitcoin.
