Solar power

It is with great joy that i found this solar powered shower at Ipanema Beach. As a citizen, and environmentally conscious and passionate engineer, and a just-about-everything-enthusiast, i was thrilled to see we have these now... They haven´t been around for long, and even if the efficiency of photovoltaics is still around 10-15%¨, we have enough sun to power many! The weather we had this week is living proof:)
