Solar technology is really useful, but often the issue of the size of the solar panels is a stumbling block. With that in mind, the smart folks over at MIT have come up with a nanotube antenna that can capture and focus light energy, potentially allowing much smaller and more powerful solar arrays. The researchers claim that the nanotubes currently lose about 13 percent of the energy that they absorb but they’re already working on new antennas that could lose only 1 percent. We hope the research goes well, after all, we can’t really say no to smaller (and hopefully cheaper) solar technology devices in the future.
