The development and commercialization of wireless power transfer (i.e. moving massive amounts of power across long distances without any cables or wires) has been as elusive as cold fusion for decades — aside from a few recent attempts to charge cell phones from a few cm away.
According to TechCrunch, however, Andreessen-backed uBeam is making at least taking theoretical steps in the right direction using ultrasound. This deep-dive into how it theoretically works is illuminating, but creates as many questions as it answers.
Could we soon be able to power homes, remote research stations, and yes, even our cell phones, without the need for direct contact? What do you think?
