> Due to its very low power density, conversion efficiency and high cost, a 14C betavoltaic device is very similar to other existing betavoltaic devices which are suited to niche applications needing very little power (microwatts) for several years
- foxglacier 2y agoIt has to be more than "several" years since a watch battery can already deliver microwatts for several years in a watch.
- science4sail 2y ago"several years" is an understatement - given that carbon-14's half-life is ~5000 years, it's more like several Pluto years, not Earth years.
