A new company is looking to take human pee, or any other water source that’s near by, and turn it into a sustainable energy source for a portable charger. The company, SiGNa Chemistry, has developed a product called the PowerTrekk. The PowerTrekk system uses sodium silicide cartridges, along with any water-based source, to make hydrogen, which the device runs through a fuel cell to generate electricity. The fuel cell is made up from a replaceable cartridge. One cartridge will charge up an iPhone about one and a half times. It’s not a cheap solution. The unit will cost $200, and the cartridges will cost an additional $4. The first retailer to pick up the system for resale is REI, not surprising since this unit is being directed more towards those who do not have access to a local power source. Unfortunately, the PowerTrekk costs more than portable solar based chargers, that take just as much time to keep your iPhone, GPS, or laptop powered up out in the backwoods. Still, kudos to SiGNa Chemistry for brining the first hydrogen based portable charging system to the market. Hopefully, one day they can get the scale of economies needed to bring the cost down.
