Large Induction Coil 1901

A NEW INDUCTION COIL.
BY PROF. W. C. PECKHAM.
When the discovery of the Roentgen rays was announced five years ago, the induction coil was in the condition in which it had been for many years. There had been no demand for its development. It was regarded as an instrument for the display of certain striking and beautiful electrical effects but of little value even for purposes of instruction.

Parabolic Trough Solar Collector

Parabolic Trough Solar Collector

Its shape focuses the sun's radiation on a linear receiver located at the focus of the parabola. The receiver is an absorbing tube positioned in the troughs focal plane and runs the length of the trough. Fluid flowing through the tube, circulates through heat exchangers where high pressure superheated steam is generated.

Parabolic Solar Dish Collector

Parabolic Solar Dish Collector

Parabolic Dish Collector will focus the sun’s energy on a small precise focal point, allowing the sunlight to produce heat.

Solar Vacuum Tube Glass to Metal

Solar Vacuum Tube Glass to Metal

The comparatively thick wall of the NARVA glass-metal vacuum tubes combined with the external coating gives the tubes a high level of resistance to breakage by flying debris or hail. The low iron glass and having only one layer instead of 2 layers as with glass-glass tubes gives a final transmission of approximately 96% efficiency in the collection of solar radiation.
