Reliability

Reliability and durability are reflected qu antitatively in several ways in this characterization. First, availability is already at high levels for given c urrent initial turbine cost, O&M cost, and system lifetime. Second, the decline of annual O&M costs after 2005 reflects increased reliability. The decline in per-kWh O&M costs between 1996 and 2005 is assumed to be due more to increased energy output per turbine than increased levels of reliability. This is a conservativ e assumption, since R&D is exp ected to result in more reliable systems in this time frame as well. Third, major overhauls and replacement costs decrease over time, reflecting an increase in durability and maintenance intervals for each period's stated initial capital cost level. Finally, the reductions in initial capital cost for the same size turbine and same assumed turbine lifetime after year 2005 reflect the expected trend towards increased lifetime/cost ratios made possible by R&D.

Solar Stirling Engine Basics Explained

The solar Stirling engine is progressively becoming a viable alternative to solar panels for its higher efficiency. Stirling engines might be the best way to harvest the power provided by the sun. This is an easy-to-understand explanation of how Stirling engines work, the different types, and why they are more efficient than steam engines.
