Eco house of the future (cold climate.)
The development of most eco houses in cold climates could include electricity generated from Photo Voltaics and a heat pump for house heating and hot water. Energy storage can be provided by a diffuser to split water into H2 and O2 which can then combine in a fuel cell to provide power at night or when sun power is low. The heat pump provides up to 5 times the heat energy of the electrical energy used to drive it.
