| The need    Burning oil for heat to make electricity gives us global warming, 20% of the world’s population moving from coastal flooding,forced obeisance to the MidEast oil potentates, and no polar bears.
 At 20% conversion efficiency, the 1 TW electric power used by the US could be replaced by a solar concentrator field 75 miles square.
 Average US commercial costs for power consumed (2008)  
Electricity:  10.4˘/kWh     Natural gas: 5.0 ˘/kWh of heat     Coal: 1.5˘/kWh of heat
 The competition (in Arizona location)Photovoltaic panels:                        27 ˘/kWh electricity
 Advanced trough collector:              17 ˘/kWh electricity
 Except for having the taxpayer pay for half the cost, investing in solar power is not a rational economic decision, but a political statement.  A “go green” statement. We are changing the game:delivering heat and electricity at a lower cost than the customer pays now… 
                    before he harvests the tax breaks and rebates.
 The technology:A linear Fresnel concentrator is made of many parallel mirror strips, each tilted at the precise angle to reflect a bar of sunlight onto an elevated black receiver tube.
 The strips are motorized to rotate together:  as the sun moves one degree, each strip rotates precisely ˝ degree, to keep the light bar reflected on the receiver.
 This decades-old concept has never been implemented in a way that is simply low cost.
 We do that.
 By detailed projections, our expected costs for delivered power, without including subsidies and incentives, are:
 1.3˘/  kWh of heat, customer-selectable from 200°F to 500°F
 11.7˘/kWh of electricity (turbine; 2 football-field array):
 2.3˘/  kWh for combined electricity and heat: cogeneration
 The market:Flat roofs of commercial buildings.  5.5 Billion square feet of available flat, unshaded roof in the US alone.
 The solar power is harvested on the roof;  electricity goes into the grid; the heat goes right below to power air connditioning, space heating, industrial processes.
