Using a friction drill
Friction drills used to build powerful connections, as it does not remove metal from the hole, but the melt and create a strong wall around the hole. So, a screw can be caught […]
Bicycle without chain
CeramicSpeed The company recently built a prototype drive system for bicycles, which uses a shaft instead of the traditional chain. The company claims that the new system offers 99% efficiency (or else 1% loss […]
How spiders use their silk to fly
Some species of spiders are able to fly using the technique of balloon flight (ballooning). Ejects a net of silk fibers until the air friction on the fibers to be large enough to […]
Quantum buoyancy in a Möbius strip
The strip or tape of blamable (Möbius Strip) is a particularly simple construction showing that two surfaces can be converted into a single. On such a strip, Students constructed a quantum buoyancy system, […]
Levitating solar motors
Russian electronic Dmitry Korzefski, constructed a motor that runs on solar energy and hangs with the help of a few magnets. The construction seems pretty efficient, as there are no friction.
