The company plans to launch a more powerful one-watt version later this year, with uses ranging from consumer electronics to drones capable of flying continuously without recharging.
The idea of using this for a drone is laughable. Their coin-size battery produces 100 uW of power, so a small drone drawing a couple dozen watts would need to somehow carry hundreds of thousands of these batteries. Even if they’re only a gram each, that’s still hundreds of kilograms of weight.
Use in consumer electronics is also a terrible idea. Ionization smoke detectors are already regulated due to their americium content; imagine how hard it would be to get regulatory approval for something 100,000 times more radioactive.
If you don’t mind the (slight but nonetheless present) quality loss. Not quite worth it to me since I can always copy large videos off my phone to free up space.
