Solar Shower heats water in two hours

Fill the tank at the bottom of this Solar Power Shower, place it in a sunny spot, and two hours later you have 8 liters of 140-degree water. It's a lot more sophisticated than a simple camping solar shower, because this one mixes that 140° water with cool water from the garden hose, giving you plenty of toasty warm water at just the right temperature.

Because it's only using part of that heated water at a time, the manufacturer says "you and your family can take several showers consecutively before the tank needs to reheat." Might be a good $200 way to comfortably rinse off sand without tracking it all over your beachside McMansion.
