Fajny bajer.

Wi-Charge’s approach uses a transmitter mounted on the ceiling that converts energy into infrared light. The light then gets beamed across an open area where a device receives the light and converts it into energy. The result is a wireless, dockless charging solution that can power devices with the same ease with which people connect to Wi-Fi — but without a password.

Wi-Charge’s technology can also deliver a wide range of wattage — from a few milliwatts capable of powering small sensors, to hundreds of watts, which can be used in industrial or even military applications. In contrast, Yank Tech’s The MotherBox is promising to provide wireless charging for Android and iOS devices at a rate of two to 10 watts, depending on the distance. The added power of Wi-Charge’s infrared system allows its applications to broaden beyond making sure everyone’s smartphones don’t die in the middle of a Netflix show.

This kind of charging capacity and capability could lend itself to our efforts to further the adoption of electric vehicles, as it would enable electric cars to support long-range driving.

@PanLogik: Bardzo ciekawe ale i tak jeszcze standardowe ładowarki nie odejdą od lamusa.

To się ładuje wiązką podczerwieni? Ale jak? Jak prąd zamieniany jest na fale podczerwoną, a następnie przekształcany z powrotem na prąd w odbiorniku? Jakie straty na przesyle występują, ktoś coś?
