Back in 2012, I picked up energy harvesting as one of my major project for wireless communications masters at NUS. Towards the end of masters I came up with a commercial idea of using energy harvesting for charging. Thus for summer that year, I ended up attending founders institute with idea of somehow commercializing wireless energy transfer. We got a team of friends, with my roommate PhD in physics, and a friend from electronics, and another friend from MS- mechatronics.<p>I proposed using wireless charging at short distance, after meandering for weeks with best use case, we ended up pursuing wireless charging for robots. Thus FLUXCHARGE1 came into existence.<p>When we realized that patent would be a major issue, which at that time was with Witricity2, we had to give up on the idea.<p>I did a quick homework of the situation and things haven’t changed much in four years. There are two major companies now pursuing it, (as mentioned here)
