Thermal batteries: how to passively store heat

...at was heated by thermal solar panels. MIT Solar House thermal battery via Wikimedia What are phase change thermal batteries? Taking advantage of a 'phase change' raises the bar a bit - stick with me, it will be fun, I promise :) A significant input of energy is required to cause a material to change from a...

...agine a steam engine where water is boiled, and steam turns a piston. A Stirling engine heats and cools gas, and the gas expands and contracts as that happens. As the gas is heated by the thermal battery, it expands and forces a piston. Gas is cooled in the cycle, then re-heated again by the thermal battery. This proce...

...is house, an air-to-air heat pump that extracts heat from outside air to heat inside air, and an air-to-water heat pump. The air to water heat pump extracts heat from ambient air inside the home and transfers it to the hot water tank, offering efficient air conditioning in summer. As for heat storage, a thermal batte...

...ar City is not available in Canada, so neither is the Solar Roof at this time. Again, speaking to the lack of information: PV panels change light into electrical current, and their conversion rate ranges from 6% up to around 20%. What that means, is that of the amount of sun hitting a panel, between 6 and 20% is co...

...aking, a solarium is not a greenhouse, but can be used as such. The typical solarium is usually a glazed space adjacent to a dwelling, separated by an exterior wall and accessed through a door. Roofs are sometimes glazed, but not necessarily. Other solariums are permanently integrated into the living space and cannot...
