Alex Gadsden, Inventor
Alex - Hi. I'm Alex Gadsden, inventor of Cyclean which is a pedal-powered washing machine.
Ben - So how does this actually work?
Alex - Well straightforwardly, it’s built by recycled components. It puts a bike together with a washing machine using the crucial part which is a hand-built, universal joint. Because the machine likes to move around and do its own thing, you've got to work with it - creating this universal joint cable gave it the flow and just made it work.
Ben - Electric washing machines are very energy-intensive, but spin at ridiculous rates. What sort of spin rate can you get from gearing up a bicycle.
Alex - Well, with the gearing we’ve got at the moment, we’ve got 520 rpm and that's on just a very easy spin cycle but if you really want to push it, you can get a 1,000 rpm out of it, no worries.
Ben - How clean does it get the clothes? Is it as good as using all the electricity?
Alex - Whiter than white!
They already do. Giros power lights as you ride(we can debate if that a machine ofcourse) Wiybit, Wed, 30th Mar 2011
An energetic cyclist can maintain an output of about 200 Watts, enough for spinning and churning no doubt but heating would take a long time. syhprum, Wed, 30th Mar 2011
No no no! You cannot create extra energy by using pulley systems or levers. You can give yourself a mechanical advantage using a lever or a pulley; but you can never generate more power or get more energy. And if it gets easier you are, on the whole, putting less energy into the system and thus less can be extracted. imatfaal, Wed, 30th Mar 2011
Nope. Lower gearing can make it easier on your legs to turn a dynamo, but you'll only turn it ve-e-e-ery slowly, and the amount of power you generate depends on how fast you can turn it.
Rosy - dead right on the physics/thermodynamics, not so sure about the biomechanics.
You may be able to spin the drum but for how long? It would not be possible to heat the water. Most modern machines are cold fill. Most of the energy is used heating the water. Pumblechook, Thu, 31st Mar 2011
The most efficient way to heat the water would be to turn the drum, so the water tumbles inside it and is heated by work done against viscosity.
hi alex I always think about that but I coudn't do it because I'm not good in engineering I'm a physian in Brazil I congratulate you for this invention . Maria do Carmo Nascimento 11th December 2014 maria do carmo nascimento, Thu, 11th Dec 2014
