Bicycle without chain
(32) | 10/07/2018 | Translate: 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 of energy), and reduction of friction 49% compared to a chain system.

Hydrofoil bike After 5 years of development, the hydrofoil bike of the Manta5 company from New Zealand is on sale. It is a bicycle that works like hydrofoil sea boats, having fins called hydrofoils. Above a certain speed, the bike leaves the surface of the water resulting in zero friction.- Bicycle with 0.5 + 0.5 wheels User The Q built a prototype bike with two half rear wheels. The wheels are connected by a chain, so that one of the two always has contact with the ground.
- The rotational waterslide An original water slide which rotates about a fixed axis, manufactured in Germany by Wiegand-Maelzer. This is the first test.
- A flying wind turbine The original turbine of company Altaeros Energies, located within an inflatable shell that contains helium and may be suspended at a height of 300 meters the agent is more than double energy than conventional turbines.
- Airless bicycle tires The company is developing a new Britek tire technology for bicycles, that doesn't need air. Although details are not disclosed by the company, She argues that these new tires will be revolutionary. Many, of course, comment on how the tire will have a bad performance in muddy and wet ground.
- The most secure anti-theft system for bikes This system does not exist on the market. Is a prototype of the Conrad company which plans to launch in the near future.
- Electric vehicle with 18 wheels The original electric ATV of the company 18WHEELS from Finland, which features 18 self-powered wheels on an unusual suspension.
- Making a bike without a chain The Q tried to build a makeshift bike without a chain. Smart, but not so practical.
- A bicycle on the subway rails On Sunday, September 19, 2021 in New York, a bicycle fell on the subway rails. Passing over him, the trains sparked on the rails. It was a bicycle "Citi Bike" of the city self-service bicycle system, and the person who threw it fled before reaching the subway.
- Running on a big gym treadmill The saturn corridor 450-300rs of the company h / p / cosmos has 3x4 dimensions,5 meters and is made for training with a bike and skates. It has an automatic lifting mechanism for uphill training.
- A police weapon lock opens in 1 second The ELS 300 lock from Big Sky Racks, is a weapon locking system used by the police in the USA, and is placed inside patrol cars. LockPickingLawyer managed to open such a lock with two methods, in just a second.
- Test of the Stipa-Caproni experimental aircraft (1933) Stο Stipa-Caproni, was an experimental Italian aircraft designed in 1932 by Luigi Stipa and built by Caproni. It had a hollow barrel-shaped shaft with the engine and propeller completely surrounded by the fuselage. In essence, the whole fuselage was a simple conduit. Although Regia Aeronautica (Italian Royal Air Force) was not interested in continuing the development of Stipa-Caproni, its design inspired the development of the jet engine.
- Creative advertising A very original advertisement of the Japanese company Kandenko, which builds power supply infrastructure and electricity networks.
- Electric arc furnace The electric arc furnace is a huge refractory boiler in which metals from three huge graphite electrodes are melted. You can also see in the video a cooling system that constantly sprays water on the surface of the electrodes. The smelting furnace is used for smelting scrap and ore. Its biggest disadvantage is the huge energy consumption and electric melting is efficient only when carried out on a large scale. The theoretical amount of energy required to melt 1 ton of waste is 300 kWh.
- Euler disk rotates for a long time The Euler disk was invented by Joseph Bendik and is used to visualize and study the dynamic system of a rotating disk on a flat or slightly curved surface.. If we take a currency in the same way, the rotation won't last long. Instead, the rotation of the Disk Euler's lasts much longer and this is mainly due to less friction because the glass surface, but the great mass of the disk. This phenomenon was studied first by the Leonard Euler in the 18th century, from where it gets its name.
I would be interested to know how to resist the rise, If you find a very strong, will support those gears. They will not slip as in this case no supports are seen, this would be very good to know.
