The Cornerstone Sustainable Energy, LLC.’s (Stock Symbol: RCVA) PwrCor™ Engine is a thermal hydraulic engine that operates without combustion and is fueled solely using hot water. The purpose of the engine is to drive pumps and generators with less energy and more efficiency than other more conventional methods and the engine can perform this task in a much more economic way than even other alternative energy engines.
Sustainable Energy’s Pwrcor™ Engine has a three step process that begins with the collection of heated water which then enters a heat exchanger. After that, the heat from the water is transferred to the working fluid. The working fluid can be anything with a high enough coefficient of expansion, but typically it is CO2 in its liquefied state. As the fluid expands the piston goes up into the cylinder providing power. Then the liquid cools and contracts and the cycle starts from the top.
The optimum differential between hot and cold water being applied to the Engine’s heat exchanger can be anywhere between 185°F and 85°F. This heat can come from virtually any source from geothermal heat, to solar heat to thermal energy recovery (waste heat).
This also makes the Pwrcor™ Engine one of the greenest technologies because does not operate using fossil fuels and therefore produces absolutely zero emissions or pollution. Even better is that it can reduce the emissions of existing installations by running off of the heat they produce all while optimizing their own efficiency. The technology boasts a small carbon footprint, is virtually silent and fits perfectly with any alternative energy applications in both municipal and remote locations.
About Cornerstone Sustainable Energy, LLC.
Cornerstone Sustainable Energy, LLC. (CSE) sees enormous potential in the more reliable, free, abundant and virtually inexhaustible, sources of “green” energy such as geothermal heat and solar heat. This also includes the easily tapped sources of energy from the heat of stranded gas and biogas combustion as well as a near infinite opportunity in the area of waste heat. CSE taps these practical and much lower-cost energy resources to dramatically improve not only the environmental impacts of a customer’s power usage but also its efficiency and cost.
Although everybody likes the idea of “going green”, few people were able to spend the money that it used to require. CSE provides a more practical alternative energy solution that can make a customer’s power generation even more efficient, and can help them tap into renewable sources and qualify them as a provider of renewable energy.
