Another material worked on by Brevier Technical Ceramics is Silicon nitride (Si 3N 4) plays at present a dominant role amongst nitride ceramics. It achieves a combination of outstanding material properties not yet reached by other ceramics, namely high toughness, high strength, even at high temperatures, outstanding thermal shock resistance, remarkable resistance to wear, low [...]

Thinning the brick wall but keeping it’s insulation capacity, Fraunhofer Institute for Solar Energy Systems is leading the way with phase changing materials or PCM’s. “The new construction materials are of particular interest for lightweight structures. A layer of PCM plaster approximately 1.5 cm thick has the same heat capacity as a concrete or brick [...]

Building a large scale heat exchanger is relatively simple and straightforward.
Geothermal heat pumps green or not so green?
Posted in Heat on January 13, 2010 | Leave a Comment »
“At first glance, the green credentials of ground source heat pumps (GSHPs) look unquestionable: because you’re harvesting free heat from the ground, you can get up to four times more energy out of the system than you put into it. Sure, it runs on electricity, which is more carbon intensive than gas, but because of this favourable [...]

What if heat sinks were made to reflect different colors based on their current temperature state? In other words as heat passed through the pins they would change color, for example, become red when hot and fade back to blue when cool. The following images were taken from the Novel Concepts, Inc. website. While these [...]

A heat exchanger transfers heat from one medium to another. A good heat exchanger will conduct this transfer of heat in the most efficient way possible. What we refer to as heat is actually energy. Thermal energy wants to be in a a state of equilibrium and thus will move from a colder state to [...]
Passive Housing

While they may be referred to as “Passive Houses” they are actively taking global warming by the reigns and significantly decreasing the amount of energy needed to heat a typical home. As written in the New York Times article, No Furnaces but Heat Aplenty in ‘Passive Houses’, “There are now an estimated 15,000 passive houses [...]
