Design a new way to power something you use everyday.
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.
Your objective: Design a new way to power something you use every day.
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!
This objective is worth +10 resourcefulness.

In terms of the Pee-thing, could they be implemented with toilets at home? As well as having a solar-powered home, going to urinate could also help power your house! Each toilet would have a filter that would drain flushed liquids and then distribute it onto the chloride paper. The toilet would have a built-in LCD screen which would tell people when the chloride paper was almost finished so that people could go out and buy some more handy-packs (which include toilet paper AND chloride paper in the same packaging). The user would simply insert another piece of chloride paper and continue to power their house by urinating.
This is quite funny. :)

I did not come up with this idea but it is an amazing one. Batteries designed to run on pee. I know it sounds low brow but it is going to make someone alot of money. It is basically a chemical reaction to pee and copper chloride paper.
"Scientists have developed a way to turn pee into electricity. And there's plenty where that came from, they point out.
Cheap, disposable, and renewable, urine-powered batteries may be the perfect power source for disposable healthcare test kits called biochips, the researchers say.
"We are striving to develop cheap, disposable credit card-sized biochips for disease detection," said battery developer Ki Bang Lee. "Our battery can be easily integrated into such devices, supplying electricity upon contact with biofluids such as urine."
Scientists around the world are clamoring to design inexpensive biochips to quickly test for a variety of diseases. But no one has been able to make a similarly small and inexpensive power source.
Lee and his team of researchers at Singapore's Institute of Bioengineering and Nanotechnology have tackled this problem by using the very substance being tested - urine - to power the test.
To make the battery, Lee and his team soaked a piece of paper in copper chloride and then sandwiched it between strips of magnesium and copper. Then they laminated the credit card-sized unit between transparent plastic films.
When a drop of urine is added to the copper chloride paper, a chemical reaction takes place and produces electricity, which is harnessed by the battery. A few drops will generate about 1.5 volts, the same as a AA battery. The battery needs to be developed further to make it commercially viable.
"Our urine-activated battery would be integrated into biochip systems for healthcare diagnostic applications," Lee said.
Lee and his team also found that they could alter the battery's performance - voltage, power, or duration - by adjusting the design or materials.
The chemical composition of urine indicates a person's general health and is widely used in diagnostic tests. For instance, doctors measure the concentration of the sugar glucose to determine whether someone is diabetic.
Lee predicts that one day people will be able to monitor their own health at home using biochips powered by this type of battery.
"These fully-integrated biochip systems have a huge market potential," Lee said.
Appeeantly these pee powered batteries are available in Japan. Are you PEEPARED?

Hello my fellow Evokians
I had a dream around twenty years ago and when i woke up i knew that it was something that I want to make. If I could make this I will add jobs where there are none and help our ailing economy.
I want to make a car that is very lightweight and the shape is semi-spherical. The method of running the car is such that there is a ball in the place of the eccelerator . You would use your foot to spin the ball which causes an electromagnetic induction. "Electromagnetic induction is the production of voltage across a conductor situated in a changing magnetic field or a conductor moving through a stationary magnetic field. Michael Faraday is generally credited with the discovery of the induction phenomenon in 1831 (1) I imagine that I would have to build an electric motor that would have enough torque to supply the amount of energy needed to move the vehicle.
1. The circuit must be closed, otherwise electric charges carried by the current acc**ulate at its ends and those acc**ulations create their own electric field, stopping the flow of any additional current.
2. If a current does flow, it contributes its own magnetic field, modifying the one creating it and generally weakening it.
3. If some more complicated relation takes the place of Ohm's Law (as happens, for instance, in plasmas), that relation rules the current flow, often making it more complex.(2)
4. --And... if there is NO electric conductor in the region of changing magnetic field, NO electric current flows. However, there still exists an "induced" electric field E, a modification of the properties of space, though without any material on which it acts, it would be hard to detect it. (2)
So ive found a concept for Description of motion in one dimension from Hyperphysics
Description of Motion in One Dimension
Motion is described in terms of displacement (x), time (t), velocity (v), and acceleration (a). Velocity is the rate of change of displacement and the acceleration is the rate of change of velocity. The average velocity and average acceleration are defined by the relationships:(3)
So this makes me wonder if you can make the acceleration rate climb by using this (ball to connect to induction motor) if my idea will work.
In any case I know that in the US we need jobs to replace outsourced jobs that are never coming back. I would love to design a car that based on the induction method or other electrical sources that are small enough to drive to do errands and at the same time cut down on energy used to do so. I will add my drawing of the car soon. I do not understand the laws of physics to properly show the scale of the motor needed nor the size of the vehicle but I believe it can be done.

Atomic fusion. Not fission, fusion. They are recreating (mini) stars in britain by experimenting with atomic fusions, and that could deffinitly power about half of the united states if the energy could be harnessed.

An old video about burning Salt-water as fuel:
http://www.youtube.com/watch?v=Tf4gOS8aoFk
The problem with is that they can not burn the water efficiently enough. The free energy argument is difficult to solve as you cannot create energy, only extract or transmogrify it from somewhere else.

There are two ways to go about developing new energy sources for the future. Nuclear power and solar energy. Nuclear fission produces a massive amount of energy, just take a look at the sun. Advancing in this power will make present plants more efficient but also safer then they have been. I saw a show on putting solar panels in space and beaming the energy back down to earth. They said this is worlds more efficient because of our atmosphere and how it diminishes the power of the sun. A new technology has been tested that will make it possible to beam the energy from space to a pinpointed location on earth. Although we might not see these for awhile at least one of these will be the way of the future.

i like the idea of a solor/kinetic energy as Jassiel is talking about but here is what i took for the keywords. (Your solution should be cheaper, or more sustainable, than your current power source.)
hmm kinetic might work

hmm this is a interesting challenge for one reason we have to show a working model. so far we have not had to show a working model by us but i like it. you can see my page here http://www.urgentevoke.com/profile/steveward

Something interesting is that the sun provides the majority of energy here on earth, like Boudewijn said. It powers the wind and the water cycle and plants and by extension things that eat plants, and many other things too. We really would be a dead planet without it.

im thinking using potatoes and oranges to power small toys and things like game consoles with a universal jack that you can use for cell phones, consioles, and even small appliances.

There is only one source of sustainability and that is the sun. As long as the sun lives we have power. Powered by solar collectors which become more effective every year. (But the require rare resources like gallium or tellurium)
The sun also powers the wind. Unfortunately wind energy powered by windwills has been proven inefficient.
I think that powering something with human motion (like a bike or this merry-go-around) is not exactly what we are looking for. Human bodies need power. Power attained by food.
But here creative minds can come in to play.

Hand crank flash light, instead of using a night light, keep your hand cranked flash light ready by your bed side. Crank up as needed.
Another type is the "shake" and shine flashlight, as shown here, which lasts 10,000hours due to use of led.
