Herr Fedor Seidler has forwarded a link to several lengthy documents summarizing the work of Albert Betz, Ludwig Prandtl, and their colleagues at the University of Göttingen.

The California Energy Commission released a draft report that outlines what some call “aggressive” goals for offshore wind energy development in the Pacific Ocean — and Morro Bay will likely play a key role in helping the state achieve its targets.

Included in the correspondence from Palmer Putnam to Herman Drees is a letter from Richard Heckscher who was involved in blade development on the Smith-Putnam project. (See Palmer Putnam to Herman Drees Letter Reveals Emphasis on Swept Area.) Hecksher had alerted Putnam to the work of Herman Drees in developing Drees’ Cycloturbine.

Wally Thompson forwarded to me some fascinating correspondence from Palmer Putnam to Herman Drees of Pinson Cycloturbine fame.

Experts cite Scottish example, with turbines along roads and rail lines, as a way to make better use of ‘cheap, clean’ energy source

Block Island, off the New England coast, overcame political strife to lead the way on energy independence.

The United States set a major renewable energy milestone last Tuesday: wind power was the second-highest source of electricity for the first time since the Energy Information Administration began gathering the data.

Plans for 17 or more offshore wind turbine arrays off the U.S. East Coast mean more imminent peril for the endangered North Atlantic right whale – unless regulators and wind power developers implement sweeping new protection for the animals, according to one expert on the species.

In order to help civilians, the World Wind Energy Association WWEA and the Global 100% Renewable Energy Platform Global100RE, supported by Global100RE Ambassador Ruslana, are calling for donations of equipment which can supply power independently from the national grid, after all small and stand alone solar systems including batteries, power banks etc.
