Solar Thermal Water Heater For Less Than Five Dollars

A tutorial going over construction of a simple solar powered hot water heater. The 'five dollar' price is under the assumption you have access to a pile of discarded parts, so I'd expect a higher cost. For example, a solar hot water heater is a simple device, you have a sheet of glass behind which is located some piping to pump water which is heated by sunlight. The tutorial suggests using discarded heat exchangers from old refrigerators with slight modifications.
