People have been enjoying Marie-Claude’s Friday Gadget Feature so much, they’ve been sending me their ideas. Since I’m on vacation I asked Raye Dean to share her’s with you.

Anemometer – Steam-era Gadget
The first description of such a device comes from approximately 1450 and given by Leon Battista Alberti (an Italian Architect). He described a disc, perpendicular to the wind, that rotated due to the wind’s force.
The Illustration shows a ‘Cup Anemometer’ and measures the wind’s speed. This particular version of the gadget was invented by John Thomas Romney Robinson in 1846.
The name of the device comes from the Greek word for wind “Anemos” or “Anemoi” the Gods of wind.
