Sorry to be critical/cynical, but isn't this just a resurfacing of the widely-discredited nuclear diamond battery? [1] This looks identical. 100µW, diamond etc. How they plan to go from 100µW to 1W is dubious at best. They'll stack 10k of these? Ok. Maybe. Then how they go from that to powering drones? Come on. ~100W minimum for a small consumer drone with a camera. So stack 1 million? [1] EEVBlog: https://www.youtube.com/watch?v=5M5MF6KE-jY https://www.youtube.com/watch?v=5M5MF6KE-jY
