All you need to do with the Ibasei Cappa generator is to submerge it in fast-moving water, and it will get to work right away – no frills or strings attached. This is made possible thanks to a tapered diffuser housing which will increase the speed of water that flows through the turbine, helping boost the total amount of power it is capable of delivering. Having a maximum power delivery of approximately 250 watts, it is enough to power a notebook, but high powered items like a microwave is out of the question. The Ibasei Cappa generator will cost around $12,000 a pop, making it out of reach of the masses.
