Once upon a time, in a simpler age when electricity was expensive or balky, windup razors were popular in Europe and Russia.
In the Space Age, you could even buy the NASA-approved version!
But except for vintage models
(a mere $100.00), purely mechanical razors seem to have vanished from the marketplace. Although in this era of environmentalism, it seems they should fulfill a certain demand.
The closest such product I can find cheats by using electricity--though it is
Start with a normal bicycle. Remove the pedals and seat. Add a harness to hang in, and you've got the Fliz. More at fliz-concept.blogspot.com
What a brilliant invention! Mouse-killing pantyhose. These were unveiled in 1941 at the Annual Congress of the Inventors of America in Dallas, but they never appear to have gone into commercial production.
Patented by Benjamin Oppenheimer in 1879
. I wonder if he ever tried testing it.
Be it known that I, Benjamin B. Oppenheimer, of Trenton, in the county of Gibson and State of Tennessee, have invented a new and Improved Fire-Escape, of which the following is a specification.
The accompanying drawing represents a side view of a person with my improved fire escape or safety device, by which a person may safely jump out of the window of a burning building from any height; and land, without injury and without the least damage, on the ground; and it consists of a parachute attached, in suitable manner, to the upper part of the body, in combination with overshoes having elastic bottom pads of suitable thickness to take up the concussion with the ground.

. Most conferences would be livened up by this gadget. Would be useful at the Oscars as well.
Trick Rostrum Makes Long Stories Short
Scientists rigged up this remote-controlled rostrum to gag long-winded speakers. If a speaker talks too long, a puff of smoke blows up in his face and laugh-provoking cartoons appear on a screen behind him. The electronic gadgets at the chairman's elbow also speed up the clock when a talker gets behind schedule and warn him two minutes before he is due for "the works." Standard Oil scientists say the system has cut down wordage at meetings.
Add this to the 'inventions that flopped' folder. Susan Flynn, 20, gets ready to enjoy the "Turkobath" (i.e. a portable Turkish bath). This 1956 invention consisted of "a slotted plastic sheet with rubber suction cups that turn an ordinary home bathtub into a steam cabinet."
I can imagine that as the bath water cooled, you were left with a cold piece of plastic wrapped around you.
Urine-powered batteries have been around a long time, but have been lacking in practical applications. But now researchers at the Bristol Robotics Laboratory have souped one up enough to get it to charge a mobile phone. Looks a bit big, but if they could shrink it down enough to fit in a briefcase, you'd never run out of juice.
Invented in 1965 by William Wilson of Wyandotte, Michigan who claimed that his mirrors filtered out "sunburn radiation" leaving only "tanning radiation" and therefore gave a "blisterless, heatless, burnless, lotionless suntan." He's keeping a close eye here on the subject of one of his tanning experiments.
