Microsoft’s Lamp Phone Charger Is In Development
Will we really be able to use Microsoft’s Lamp Phone Charger? Microsoft have quite remarkably designed a lamp that will charge your mobile phone just by shining a light onto it. This really is like something out of a Science Fiction film! Tests have been conducted and they show that the light from the lamp can recharge a phones battery through fitted solar panels just as quickly as with the traditional wired charging.
Although Microsoft Research have built a prototype it is unlikely to see the light of day any time soon. The AutoCharge system works using cameras that will detect a phone and then angle the beam of light onto the device.
Microsoft researchers have said in a paper: “It is actually much safer than sunlight because 1) the light beam is cool light and thus causes less heat than sunlight; 2) a large part of the energy of the light beam is converted by the PV [photo-voltaic] panel into electricity and thus generates even less heat,” they state in the paper. The beam’s energy level was about 110 mW/cm2, which is only slightly higher than that of sunlight of AM1.5 spectral irradiance. The key idea of the AutoCharge approach is identifying the opportunities of smartphone charging from a user’s existing action of putting a smartphone on a desk and automatically charging the smartphone without requiring explicit effort from the user.”
