A clever British design student, Tom Broadbent, has come up with a way to harness the energy in wastewater and transform it into electricity. His device, dubbed HyDro Power, works by taking the waste water from toilets, showers, and sinks, and passes it through four turbine blades as it flows through the pipes which powers a generator.
The device is currently designed for high-rise buildings where it could generate the most energy and lead to cost savings as much as $1,415 per year for the average building. That may not sound like a lot, but you’ve got to take into account, the value of the environmental impact that the device is offsetting. If this device were to be installed during the construction of new buildings or retrofitted into existing ones, we could be looking at savings, both financially and environmentally, on a tremendous scale.
Of course, the energy converted and collected by the HyDro Power could be put back into the building or sold back to the national electrical grid. Tom Broadbent comments on his idea saying:
