I found this on the web.Talking about LARGE STIRLING ENGINES

The Stirling Energy Systems proposed Imperial County solar energy plant, to which the Sunrise Powerlink is supposedly primarily devoted, does not appear to be commercially viable any time soon (B. Powers). At best, the proposed Stirling Solar Energy Plant may not be ready until the year 2017 (California Energy Commission).

Contrary to company statements, the Stirling Energy Dish still appears to be in its experimental phase (Wall Street Journal, 11/17/05), with only a total of 6 demo prototypes having been built, at a government energy lab, to date, and an initial test installation of the worlds first 40 currently being planned for the Mojave Desert north of Los Angeles (Design News, 1/9/06). One research issue at hand is how the burning hot desert dishes will be continually cooled; 4.4 gallons per dish, per MWh, and how they need to be washed free of desert sand in order to work. A 1,200 foot test-well has already been drilled into the fragile desert water-table in Ocotillo Wells, and residents there fear that this well will bring real community ecological problems in the future. Another issue is wind; the dishes are rated on their trunk for winds up to 50 mph, a familiar wind speed in desert storms.

The number of large parabolic dishes proposed is an amazing 36,000, and even Sempra has acknowledged that its a gamble on the dishes, which have not yet been proven commercially feasible (Wall Street Journal, 11/17/05). These large industrial issues must also factor into our consumer overall estimated cost and payback of our own future alternative energy supply, in addition to the expensive cost of massive transmission, from the remote location, so far from its designated end-users.
