Re: [Vo]:More on rooftop turbines ...

There are some excellent niche markets for small wind turbines, such 
as deep water buoys and other platforms at sea. The are similar to 
solar cell installations used along isolated highways for emergency 
telephones, and for fog monitoring stations on mountain roads.

People developing expensive new technology should start in a niche 
market in which customers are happy to a premium. Solar cells took of 
in the 1980s and were greatly reduced in price when they were widely 
used for hand calculators.
