We can stuff as many powerful processors and as much memory as we want into our phones and tablets, but it won't matter unless the devices can draw enough energy to make use of it all. Even if the battery industry can produce a unit that can store significantly more energy than the average, it would still be susceptible to draining. However, what if our devices were powered by an energy harvester that could pull energy out of thin air? MicroGen Systems aims to bring that kind of device to market.
