Charles Greeley Abbott wasn’t any ordinary head of the Smithsonian Insitute. One of the world’s preeminent astrophysicists and a specialist in all things sun,  he invented one of the first solar cookers, seen above. And he happened to believe in paranormal phenomenon. All around, he must have been a pretty interesting guy, particularly after a few drinks.

Abbott wrote a book in 1938, while director of the Smithsonian, in which he ran down the state of sun science, The Sun and the Welfare of Man. The fascinating thing about this work is that it’s a scientific work about observing and measuring — spots, strength, variability, etc — that happens to include a chapter about “Harnessing the Sun.” It’s hard to imagine an astrophysicist just kind of dropping solar machines into the center of his book, but that’s what Abbott did. And along the way he provided a decently comprehensive history of early solar machines, courtesy of a many-page long quotation from A.S.E Ackerman, first published on US soil in the 1915 Smithsonian Report.

One rarely mentioned project is pictured below.

Here’s what Ackerman had to say about this very, very early solor motor:

A.G. Eneas, in the United States, used the popular truncated, cone-shaped reflector, collecting about 700 square feet of solar radiation. The weight of the reflector was 8,300 pounds.

The boiler was formed of two concentric steel tubes, the two together being incased in two glass tubes with a air space between them and another air space between the inner glass one and the outer steel tube. The water circulated up between the inner and outer steel tubes and down the inner tube. The boiler was placed at the axis of the cone. Its length was 13 feet 6 inche, its water capacity 834 pounds, and steam space 8 cubic feet. Hence the diameter of the outer tube appears to have been 1 foot 2 inches and the concentration of radiation 13.4; i.e. 13.4 square feet of sunshine were concentrated on each square foot of the external surface of the boiler…

The sun-power plant known as the Pasadena one was described and illustrated in the August, 1901, issue of Cassier’s Magazine by Prof. R.H. Thurston and on page 103 of the Railway and Engineering review of February 23, 1901. It is stated to have been designed by, and erected at hte expense of, ‘a party of Boston inventors whose names have not been made public.” …

‘According to newspaper accounts the all day average work performed by the engine is 1,400 gallons of water lifted 12 feet per minute, which is at a rate of 4 horsepower’ …

The Pasadena plant is said to have cost 1,000 pounds and Willsie, writing of it in 190, says it was the “largest and strongest of the mirror type of solar motor ever built.”
