Power House- Experiments in Sustainability in Mill Bay, British Columbia for sale

Experiments to explore sustainable energy.
You first build a styrofoam house with the pre molded panels and then conduct the experiments using the house and measuring devices such as a thermometer to see what is the most efficient way to heat and cool the house as well as other considerations. Very well put together kit made by Thames and Kosmos (The gold standard for science kits imo). Some experiments include those with solar panels, wind power generator, air conditioner, hygrometer, desalination, solar collector.
