How are you getting power to the light?
- rorykoehler 7y agoWirelessly?
- chvid 7y agoOr a battery maybe? I don't know ... if you try to think ahead of what is within the realm of physics but not yet economically or technologically viable there are actually quite a few possibilities. For the record. I don't think that there will be a physical sim card in your bathroom light but I think that all these wireless communication standards (infrared remote controls, wifi, bluetooth, 4g mobile data ...) will converge into one and the use of that will be so cheap that it will be used everywhere.
- inimino 7y agoSo you'd rather run the mains power to a device that beams power through the air to a light fixture rather than just run a wire to the light fixture?
- liability 7y agoI hope you're aware that uBeam is a scam which cannot work.
- Dylan16807 7y agoThere are perfectly valid electromagnetic methods for doing wireless power. Not that you'd ever use them for a light bulb.
- wongarsu 7y agoBeing able to mount buttons anywhere is nice, and Philips even has a switch that works without batteries (the power for the Zigbee radio comes from the button press). Sending a signal over 5G to the internet and back however sounds like peak inefficiency for two devices in the same room that could choose any local wireless protocol
- wlesieutre 7y agoThe module in that switch is made by EnOcean, they go back to at least 2006 (though the 2.4 GHz versions are more recent) https://www.automation.com/products/enocean-announces-wireless-batteryless-light-switch https://www.automation.com/products/enocean-announces-wirele...
