Elon Musk's big plan involves charging your electric car with shingles that are solar panels. While that's incredibly impressive -- not to mention ambitious -- it uses only one form of alternative energy. Finnish scientists have a different idea: harnessing heat, kinetic energy and sunlight simultaneously to help power your gadgets. This involves using a ferroelectric material (think: the stuff inside ultrasound machines or fuel injectors for diesel engines), KBNNO, to generate electricity from heat and pressure. That's according to a post on Phys.org.
