There’s a new piece of technology that could help bring clean water, electricity and even WiFi to those who need it most. Led by Italian entrepreneur Marco Attisani, Watly is a generator that uses photovoltaic solar panels to harvest energy and then stores it as electricity. The electricity is then used to purify and desalinate water from rivers and oceans.

This is a breakthrough for developing countries that desperately need access to these resources. Watch the video below to see Watly in action.
