D/P Impulse Lines; Chinese Solar Tech

How to Keep Impulse Lines Full of Water When the Pump Shuts Down, and Are the Controls, Converters or Collectors for Photovoltaic Designs Better Products?

No, this situation has nothing to do with quality, but with politics! The Chinese government can implement business strategies, which ours cannot. Just imagine how hard it would be and how long it would take to have Congress pass a regulation requiring that all U.S. government buildings be covered by American-made PV solar collectors, and also require that the cost of these installations be financed by 15-year "building improvement" mortgages?

Yet, if it were politically possible to do, the solar industry market would suddenly explode. It could hire more people, spend more money on R&D, and the local government could pick the best designs at the lowest cost. Even with the miniscule market today, the cost of solar collectors during the last years has dropped from $3.30/watt in 2008 to $1.20/watt today.

If in all areas where solar insolation exceeds 1,500 kWh/m2/yr, the government buildings ordered collectors, their production and installation would create some 1.5 to 2.0 million jobs. Such projects would do that without any cost to the taxpayers, because during the first 15 years, the monthly mortgage payment for these improvements would be less than the present monthly electricity bill and after that, the fuel (the sun) would cost nothing. Already, on a building in Westport, Conn., 46 collectors were installed at a monthly mortgage cost of $200, less than the previous monthly electricity bill of $215. Once such cost-effectiveness was proved on the government buildings, the "lack of economic feasibility" argument would be disproved, and the general public would follow the example of the government, thereby further increasing the demand. This increased market would create even more jobs, would cut energy imports even more, would allow American manufacturers to further improve their quality, further reduce costs through mass production. Higher quality and lower cost would make us a player on the global market and eventually we would beat the Chinese.
