Stirling engine micro-CHP This technology is new to the market, although the principal of the Stirling engine is well established. The electrical output is small relative to the heat output (about 6:1) but this is not necessarily a problem for micro-CHP.
Kidney damage due to a blocked artery is a rare cause of kidney pain, as is poststreptococcal glomerulonephritis, an uncommon complication of streptococcal infections, such as strep throat (bacterial throat infection) and impetigo. Some conditions that cause kidney pain can have serious complications.
