Good fishing hole: Google.com (there are others, too)
Bring up the Google search window, type "US electric powered ultralight aircraft" into the white box and hit the "Enter" key. Snoop around the results and see what you can learn. Some sites may contain links and references to other sites, so pore over them carefully. This technology is changing at a pretty good clip, so treat the older articles as historical and focus primarily on those less than a year old. If you don't have a good grasp of things electrical, you may find the learning curve a bit steep, so the level of your passion and commitment will determine the pace at which you get there.
Go fish!
