High Frequency Coils
C. A. Crowley describes the fun with high-voltage, high-frequency coils. I hope this will provide a sufficient inspiration for a modern version of this apparatus. It might make you feel like Tesla for a minute or two.

Vacuum Chiller
This article explains a simple chilling process using steam, vacuum and water; it is still the simplest and one of the environmentally friendliest methods of cooling.

Robert W. Wood
This article describes the killer high frequency sound waves traveling through water or solids discovered by Johns Hopkins scientist Robert W. Wood. Wood joined forces with Alfred Lee Loomis, a famous Wall Street tycoon, and together they have done pioneering work in the study of ultrasound.

Lieut. John Choptaw
This article describes people who had made the ultimate sacrifice while serving their scientific professions. It is astonishing how many physicians working for U.S. Health Service lost their lives.

Harry Donald Tiemann
This article describes the critical role kiln lumber drying played in winning the WWI. Effective kiln drying was perfected at Forest Products Laboratory at Madison, Wisconsin by Harry Donald Tiemann, one of the pioneering scientist at FPL. Tiemann wrote a seminal work on this subject – The Kiln Drying of Lumber .
He Revolutionized Lumber-Drying
Today Forest Product Laboratory continues in the tradition established by people like Harry Tiemann.
Hailstones
Why aren’t we killed by hailstones? Apparently we are killed, although rarely. This short article mentions the work of John Eliot in which mentions 250 death from a single hail storm in India. It also mentions a severe hail storm in Maryland on June 22, 1915 in which miraculously nobody was killed.

Magnetic Crescograph
Here is an invention by the great Indian scientist Jagadish (Jagadis) Chandra Bose, which calls magnetic crescograph. This article written by Latimer J. Wilson claims that this apparatus can detect “heart-beat” of a plant. I don’t know how this theory fares with modern biological science. Perhaps someone knowledgeable will care to share her knowledge.
