The project Vélo M2 plays with PPP (people pedal power) applications. In Brussels we're having PPP open-air cinéma projections, PPP mobile fablab workshops and PPP music scenes and DJ sets. [www.velom2.be www.velom2.be]
This projects takes the PPP to a smaller scale, where we will be charging a computer. In order to demonstrate the accessibility, we're construction the device in a remote town in Sweden, Torsby.To find out more about People Pedal Power, visit our site https://ciklic.wordpress.com/2017/08/05/renewable-energy-what-can-you-expect/
The aim of the people pedal power is to charge a computer. A computer battery is normally charges by an adapter that converts AC mains power to DC power. This charger will be only for YOUR computer.
Be informed :
- we want to charge with the same power as the adapter does
Check the voltage and the current at which the adapter charges your computer. Mine charges at 20V and 4.5A.
- you will be cutting your power cable
You can also chose to buy the plug separately and assemble a new cable.
The fist etape is the conversion of the human energy to slow-rotating mechanical energy. We are using an ordinary bicycle to harvest the energy.
Think about this :
- your bike should have low-profile tires
When the profile is too important (see picture) there will be a large energy loss due to vibrations. You will also have more noise when pedaling.
- the fixation of the axis should be not of the fast-release type
The fast-release-type with flat end (se picture) is often not compatible with the bike stands. You can easily change the axle with another (second hand) axle.
The second etape is converting the slow-turning mechanical energy of the bicycle wheel to a fast-turning mechanical energy. Electric generators like high speeds.
