Natural Water Cycle (Helen)
Water harvesting (Don)
Harvested Water Usage (Tom)
- Evaporated Sprayer System for passive cooling of the roof
- Autocool Roof System ... indicates a 50 - 70F reduction in roof temp saving 20 - 30% cooling load.
- Cool Roof Article excellent stats...including "On average, the roof accounts for 35% to 40% of a building's total heat load." This article reinforces the findings above.
- It could be PV operated because it would be hottest on a sunny day.
- Solar Shield product
- Micro-irrigation
- mirco-irrigation data overview; Univ of Florida Study
- DripWorks ...they have sprayers and misters; Drip Depot great kits
- require low-pump pressures...save energy.
- Wash cars/bikes (homeless could do people's cars)
- Use a wagon or hose to distribute water
- Thermal Storage
- hot and cold tanks
- 1 cf of water holds 9.2 kBTU of energy (e.g. 15ft x 10 x 10 = 13,800 kBTU)
- advanced thinking on thermal storage including molten salt tanks
- Solar Tubes nice moderately priced passive solar storage.
