Solar-heated portable outdoor shower

A solar-powered outdoor shower capable of heating 5.5 gallons
of water to a toasty 140 degrees Fahrenheit in just two hours on a sunny day? Uh, okay. The solar-powered
outdoor shower is also easily transportable, too, which is good because even though the manufacturer claims
it can still heat the water on hot cloudy days without direct sunshine you might want to relocate your beach party
to brighter climes.
