The author's smart home devices frequently run out of battery, highlighting a common frustration with battery-powered gadgets.
A solution tested: Wi-Charge's infrared laser wireless charging system, which keeps a smart lock perpetually charged without manual intervention.
The setup involves a Wi-Charge transmitter in the ceiling and a modified Alfred DB2S smart lock with a photovoltaic panel, costing around $1,250.
Benefits include no cords, no need for frequent battery replacements, and the convenience of battery-powered devices without their downsides.
Wi-Charge's technology uses infrared lasers to transmit power up to 10 meters, with safety certifications (FDA Class 1, FCC, UL).
Despite the high initial cost and installation effort, the author finds the system impressive and desires similar wireless power for all smart home devices.
Challenges include the need for line-of-sight, device redesigns to incorporate receivers, and the current lack of infrastructure for widespread adoption.
Potential applications extend beyond smart homes to commercial uses like digital signage, where wireless power could offer significant advantages.
Wireless power is less efficient than wired connections, but for low-power devices, the increased electricity cost is minimal.
The dream of whole-home wireless power faces hurdles, including manufacturer adoption and consumer demand for compatible devices.
