The Mini Hydro Turbine by Jin Woo Han is a concept design that produces free electricity by tapping into the water pressure in your pipes at home.

You can either use it at the end of your faucet or install it as a connector between two water pipes.

So how does it work? The Mini Hydro Turbine comes with a built in mini hydroelectronic turbine that produces electric energy from the constant water pressure. The energy is stored in a battery inside the unit. A visual indicator shows how much energy has been accumulated.

You can then tap into this energy using the attached plug socket to charge your gadgets.

So basically, you will be both saving the planet and saving up on your energy bills. Dope!
