Design changes to spine based ducks

Modifications have been made to the capital cost, productivity and availability of the 2000 MW spine based duck scheme.

The central cost estimate of the 1992 Thorpe review is 16 p/kWh, very close to the cost of wind energy in California in 1985 (an output of 671 million kWh from an investment of 1920m dollars) but certainly not low enough for any development in the United Kingdom.
Despite the extra for bridges, links, higher torque and pressure accumulators, the effects of the removal of the gyro canisters, the use of thinner concrete, the reuse of shuttering and the coronet joints rather than Hooke's joints should reduce the capital cost by a factor of about 2.
The extra productivity of complex conjugate control should give us an extra 1.5 times the energy at the generator terminals.
Most important of all will be the development of methods to send electricity reliably along the spine during the productive months. This should deliver about twice the energy to land.
