Low-temperature Stirling Engine

I’m currently working on a low-temperature engine for use in a solar-powered sculpture project. Fortunately it really doesn’t need to run anything other than itself. Ideally it will not use concentrated solar to keep the project simple although that limits the engine to a very low temperature ratio. A low temperature ratios mean low power. [...]

Concentrated Solar Power (CSP) based Electricity Generation has been Proven to be the Most Efficient Form of Renewable Energy

Most Arkansas residents are aware of the main sources of renewable energy available today: Wind, Solar, Geothermal, Biofuel and Hydroelectric. When asked most would probably envision vast wind swept hills covered with wind mills, hundreds of acres of desert packed with solar collectors, or a few photovoltaic cells on the roof of their house. Of [...]
