- gus_massa 11y agoThese other submissions were more lucky. * https://news.ycombinator.com/item?id=10308708 https://news.ycombinator.com/item?id=10308708 (7 points, 8 days ago, 6 comments ) * https://news.ycombinator.com/item?id=10323565 https://news.ycombinator.com/item?id=10323565 (2 points, 5 days ago, 7 comments) (more interesting comments) Very short version of the comments: They claim that they can harvest ~30µW, this is very little. For example, it can only blink a led a few times per minute, because a normal led use 30mW=30000µW. Read the complete comments for more details.
- littlewing 11y agoTesla had wireless power transmission working over a century ago: https://en.wikipedia.org/wiki/Wireless_power#Tesla.27s_experiments https://en.wikipedia.org/wiki/Wireless_power#Tesla.27s_exper... "At his Colorado Springs laboratory during 1899–1900, by using voltages of the order of 10 megavolts generated by an enormous coil, he was able to light three incandescent lamps at a distance of about one hundred feet."

- triplesec 11y agoThis article here https://news.ycombinator.com/item?id=8542091 https://news.ycombinator.com/item?id=8542091 is why some of the technology puffery in this WSJ article may not come true: there's been some pretty damning and serious scientific feedback om their sound-energy transmission efforts.
