H2Pro, is a portable device  powered by sunlight. Dirty water goes in one end, and a titanium mesh, activated by the sun, sterilizes the water and sends it through an extra filter. The photocatalytic reaction also splits the water into hydrogen and oxygen so someone can flip a switch and start feeding a hydrogen fuel cell to produce clean power. Detergent, soap, and other pollutants in the water help make more hydrogen.
