PowerTower is an all-in-one compact energy harvesting unit that will provide communities around the world with pasteurized water, electricity for small devices, and instant flowing hot water. Much of the third world is currently living without many of the necessities taken for granted such as running hot water, electricity, or safe water. PowerTower will allow people living in rural communities to do things as crucial as charge cell phones and have clean water. The technology will be delivered through a cross subsidization model based on a domestically profitable product using the same technology called the PowerShower. This technology is inexpensive, not susceptible to weather conditions, and makes use of an energy source already widely utilized in the third world.
