Wireless Power Across the Room: A Year with Wi-Charge

The author's frustration with constantly dying batteries in their smart home led them to test Wi-Charge's long-range wireless power technology. A ceiling-mounted transmitter uses infrared lasers to power a specially modified smart lock, eliminating the need for battery changes for a year. While the initial setup cost $1,250 and required professional installation, the convenience of cordless operation and no battery replacements was significant. However, widespread adoption faces hurdles: devices require special receivers, and the system's limited range requires multiple transmitters for whole-home coverage. The author concludes that while the technology works impressively, its high cost and infrastructure requirements remain significant barriers to broader home adoption, although it shows strong potential for commercial applications.
