A heat engine measuring only a few micrometers works as well as its larger counterpart, although it splutters What would be a case for the repair shop for a car engine is completely normal for a micro engine. If it sputters, this is caused by the thermal motions of the smallest particles, which interfere with its running. Researchers at the University of Stuttgart and the Stuttgart-based Max Planck Institute for Intelligent Systems have now observed this with a heat engine on the...

Shoppers don´t usually give a second thought as they reach into a cooler to grab milk, cheese or prepackaged lunches. Open-front refrigerated display cases, which make up roughly 60 percent of the refrigerated cases in grocery stores and supermarkets, provide quick access to chilled products such as dairy, meat, fish and produce. While they are popular with shoppers and grocery stores, they´re less popular with electric utilities  and others concerned with energy efficiency....

Researchers at the University of Hawaii at Manoa say that the Leeward side of Hawaiian Islands may be ideal for future ocean-based renewable energy plants that would use seawater from the oceans' depths to drive massive heat engines and produce steady amounts of renewable energy. The technology, referred to as Ocean Thermal Energy Conversion (OTEC), is described in the Journal of Renewable and Sustainable Energy, which is published by the American Institute of Physics (AIP). It involves...

Cyclone Power Technologies, Inc. (PINKSHEETS: CYPW) has filed a patent application with the U.S. Patent and Trademark Office on its production prototype waste heat engine (WHE). The WHE is able to convert wasted heat from sources such as ovens, furnaces and engine exhaust into mechanical energy and electricity. This process of cogeneration -- also called combined heat and power (CHP) -- can result in substantial savings to the end user and help reduce greenhouse gas emissions. The WHE is...
