Assessment of Sterling Engine concept
The article can be found here:
http://www.eurekamagazine.co.uk/article/21752/Big-valve-offers-big-opportunities-in-heat-storage.aspx
Paragraph to note: :When energy is to be extracted from the hot and cold gravel beds, argon is passed through the cold bed where it undergoes isobaric cooling which reduces the volume of the gas. It is compressed to 12bar and then rapidly injected in to the hot gravel bed. Here it undergoes sudden heating enabling it to perform work as it expands on the other side of the cylinder."
My understanding of the Sterling Engine concept is that where there is an existing heat or cold source, it can be used to oscillate weight to effect a reciprocal (albeit, weak) motion, which (if it were sufficient) can be harvested in various ways to perform other work. Reading the above article, one wonders... if just using the energy that would heat the material on one side and cool material on the other would be much more efficient... or am I missing something...
