Teenager Invents Device That Makes Clean Energy AND Fresh Water!

What with yesterday's post, it seems like everyone is getting into the clean-water-make-energy act. 17 year-old Australian student Cynthia Lam, has built the H2Pro – a portable photocatalytic electricity generation and water Purification unit that makes both clean water and energy.

“The entire process only needs titania and light — no additional power source is required. However, hydrogen production is generally low since photoexcited electrons tend to fall back to the hole (i.e. photoinduced electron-hole combination.) Fortunately, it can be overcome by adding reductants, while some organic pollutants serve such purpose. Hence, I propose to combine the two mechanisms together to enhance the yield and lower the cost of hydrogen generation, meanwhile efficient water purification can also be achieved.”

Here's some video from her on this exceptional achievement.
