Would be nice to see more of these physically feasible, but futile, mechanisms to extract energy. Just recently came to know about Atmos'clocks, for instance, and wondered if you could use something similar to power one light of your house or w/e.
- jcims 5y agoWhoa, that's a cool mechanism and even a modest volume would seem to generate quite a bit more power than the clock needs. Betavoltaics are another cool one. You wrap a beta emitter (like tritium) with a solid state 'betavoltaic' that works like a photovoltaic but for beta particles. These are commercially available and will provide microwatts of power at 1-2v for for 30+ years.
