Take a look around you. Something YOU use or do every day could be powered differently.
Your challenge this week is to DESIGN A NEW WAY TO POWER something you use everyday. Maybe it's your mobile phone. Maybe it's the light you use to read at night.
Your solution should be cheaper, or more sustainable, than your current power source.
It's an ambitious challenge -- but you're an EVOKE agent. You know that even if you fail, you can learn from your efforts... and maybe even inspire someone along the way.
Share your design in a blog post, video or image. For legendary honors, make your idea real -- and show us in photo or video your brand new power source in action!

Everyday people wash their hands and every time you was your hands, it produces energy in the entire building for the wh*** day.

I brush my hair everyday, so my invention is a brush connected to an outlet. Whenever you brush your hair it sends electricity to your house or any electronics. This invention will be very affective to many people and I hope this item will make a huge difference in the future.

By thinking about something I use every, I notice that I have not so much things I could power on a cheaper way. So I start thinking about my equipment at work and at the university. There I could find something.
I work every day with a laptop for the study or for the work. I think it could be a way to power a laptop by an dynamo. After sitting so much before a laptop it is a nice alternation to power a laptop by using a dynamo. The dynamo must not be used by hand, it could also used with a feet-pedal so that I can work by the way.
If the weather is fine enough, I prefer to sit outdoor to do my work. Additional I could power the laptop by solarenergy. While I am working indoor with the laptop I could use my own little hydropower station. It could work with a pump like a pump to clean the ground of an aquarium. On that way could arise a hydrologic cycle, which driving a water wheel that is connected with a dynamo, to produce energy without using electric-energy for the pump. The produced energy could saved in a storage battery or be used for direct loading. If there is used a storage battery you can also power different equipment like a mobile phone, a flashlight or a radio.

For this week challenge I thought about a simple way to power something of my everyday life. Each day, if the weather is fine, I am using my bike. Recently when I cycled and the sun set I had to turn on the light. On my old bike the light is generated by a dynamo. At this moment I remembered of a generator flashlight my father used a while ago. This principle to generate electricity only with muscle power has been already transferred to different areas of application (here flashlights, but also chargers and radios). On that basis I thought it would be very effective to use mechanical supercharging for example for MP3 player / iPods. Nearly every person has such a device and uses it every day or at least frequently. It is also conceivable to use that approach for a lamp to read in bed in the evening. This dynamo technology is of course very easy and favorable, independent of electricity and battery and furthermore very efficient. Different constructions may be used: a crank, hand gear, or flywheel is quite possible. Besides these possibilities you have to think about the use of incandescent lamps or LEDs. Incandescent lamps are cost-effective, reliable and generate sufficient light. But they are rather inefficient. Nearly 98 percent is lost in heat. Furthermore a limited life span is conspicuous. In contrast LEDs are very durable (about 10000 hours). But determining is the low-energy consumption and the luminous efficacy for example for a 'generator reading lamp'.
