To make such a future possible, Pint headed a research team that used scraps of steel and brass – two of the most commonly discarded materials – to create the world’s first steel-brass battery that can store energy at levels comparable to lead-acid batteries while charging and discharging at rates comparable to ultra-fast charging supercapacitors

Batteries from scrap.  Windmills for power generation.  How long for Stephen to go off grid entirely?

I believe truth and principle do matter. If you have to sacrifice them to get the results you want, then the results aren't worth it.
