Quantum entangled batteries could be the perfect power source
- stephengillie 14y agoCan we use quantum entanglement to transfer energy without a physical connection? Could we transfer enough energy to charge an iPhone?
- mrsebastian 14y agoI was trying to work out the same thing. The no-communication theorem says that you can't transfer data using entangled particles -- but would that apply to energy as well? Not sure. Need a quantum physicist...
- Kungpaoshizi 14y agoI have some batteries!
- astrodust 14y agoIs energy classified as information?
- stephengillie 14y agoNoisy, staticy, lossy EM fields do provide electromotive force. This is why data and power cables are often separated.
- astrodust 14y agoI mean in a quantum mechanical sense. (e.g. http://en.wikipedia.org/wiki/Quantum_information http://en.wikipedia.org/wiki/Quantum_information) The ability of something to cause a random side-effect does not necessarily mean that something is information.
- shardling 14y agoSince you can measure energy, it's pretty clear that it counts as information. However, the theorem you mention only rules out instantaneous transfer of information.

- DeepDuh 14y agoIt's amazing to me how many media outlets still don't optimize for embedded, given today's usage numbers.
- andrewflnr 14y agoExtremeTech does think they're optimizing for mobile, though. What's really amazing is how they apparently never use their "optimized" versions themselves.
- tzs 14y agoIt's going beyond screwing up mobile. I've noticed over the last few months a great increase in the number of major sites that are crappy on the desktop, too. For instance, many sites behave poorly if you have the audacity to use your browser's zoom feature. Their floating social sidebars intrude into the text, or the margin goes completely away, or the text extends into the sidebar. It's getting to the point where blog spam is often preferable to the original.
