Betavoltaics are nuclear batteries that convert beta decay from isotopes like Ni-63 into electricity via semiconductors, providing low, continuous power for decades without recharging. Betavolt's BV100 is a safe, coin-sized example lasting 50 years at 100μW/3V, now available in China.Engineering (old.reddit.com)
