6.1.09	The Pitfalls of and Opportunities in Electric Power Deregulation Topic: Policy, Regulatory & Legal Article Viewed 5499 Times; 84 comments The deregulation of several sectors of the national economy became the vogue during the Reagan administration in Washington and the Thatcher administration in the UK. Margaret Thatcher had read The Road to Serfdom by F.A. Hayek (nobelaureate in 1976) and was inspired to privatize some of Britain's state-owned enterprises as the socialist economies of Eastern Europe and the Soviet Union collapsed. Friederich Hayek had been a student of Ludwig von Mises whose treatise entitled Socialism detailed the downfalls of state ownership and state management of a national economy and how such an economy would ultimately fail.

5.15.09	The Great Lakes as a Hydraulic Storage Reservoir Topic: Energy Storage Article Viewed 4656 Times; 2 comments There is a growing need to develop more electrical generation capacity across North America. The market demand for electric power fluctuates almost cyclically throughout the day and creates an opportunity to develop mega-scale energy storage capacity.
