Solar Water

Here's a review and demonstration of a 5 gallon solar camp shower bag. Fill it wh water, let it warm in the sun, then take a shower. I used rainwater from my rainbarrel for this demonstration, but any water source could be used. It worked excellently, though it did make the water smell like PVC and it was heavy when full, so finding a suitable place to hang it could be a challenge. I like this system and recommend it highly.

As living standard increases, a lot of energy is being used to air-conditioned the building, to heat the water, to chill the food, and for other purposes mostly for the comfort of the people in the building. Though some of the purposes are well justified, energy demand causes fast depletion of natural resources, and thus better ways of harnessing energy from alternate and renewable sources are needed. It is also important to improve energy performance of the building, reduce energy need of the appliances, and readjust the energy consumption habit for sustainable lifestyle. To achieve the objective, many countries throughout the world have setup policies, legislation and incentives to encourage or enforce the architect to rethink and redesign the building energy efficiency, and the indoor environmental conditions. Many products have been developed, tested and deployed. Photovoltaic system and solar water heating system have both been installed and used on the roof for many years. Both serve their function well and receive great acceptance. However, both products are competing for roof space which is limited and expensive in congested city areas. It is thus not surprising that both systems should be integrated as one to complement each other. The solar collector itself can be a good choice of roofing and wall material as it comes with large flat surface, and with good tensile strength. This invention provides a cost effective roof and wall material, which also generates ...
