one of my main issues for electricity is keeping my cell phone charged. it's endless aggravation and i'm constantly searching for outlets. I know it's not sustainable and I know it's inconvenient.
I have a huge window in my office as well as living in an area that gets a lot of sun, so a natural solution is to look at cell phone chargers that are solo powered.
Two that I like: … Continue

One of my guilty pleasures is bacon.
I buy it organic, farm raised, from Niman Ranch
which is pretty good as meat-raisers go, but still, it's not very healthy and not very sustainable and such a shame that it's so very very delicious.
Like anybody who cooks bacon, or other greasy delights, I've puzzled over time about what's the most responsible way to dispose of the grease. It shouldn't go down the drain, it doesn't really belong… Continue

Okay, is not an invention!... i smoke...and i really feel bad about all my plastic lighters... so now with evoke game i evoke this ancient solution that is just a cord and your finger ...and that's it.. no FUEL whatsoever...and is great in wind!…

we are aware of the road bumps..those semicircular arc shaped piece of concrete..now, when vehicles run over it, they exert some force on it..
Now, can we not use that force to convert it into electrical energy..
Imagine zillions of vehicle producing energy daily just by running over bumps..

Try going through a freezing winter and one of the most common problems you'll run into is hot water. You gotta wait for the tap to warm up, wasting valuable water, your time, etc.
What I propose is modifying a water bed or perhaps a section of the bottom of the bed to hold water in a confined space that could be warmed overnight by the excess body heat from the people sleeping in the bed. While it wouldn't be super hot, it would be warmer than the ice cold stuff that would come out of… Continue

Alright, power design is not my forte, as I don't know how everything works, which I would prefer to before sharing ideas, but as I don't have the time or passion for this right now, how about I just shoot off some random (and probably impractical) ideas for generating small amounts of electricity for things like cell phones and music devices.
- Heel inserts (for shoes) which utilize the natural motion of walking to charge batteries.
- Solar panel which can be put in…

That boy rides his bike 100 mi a day I bet. I intend to secure a type of alternator to the boys bike that will charge a 12V battery that can be used to power the deer feeders that we use everyday. I will post a video of this in action as soon as I complete the project. Unless I blow the boy up, in which case I will send the video to America's Funniest Home Videos first. Either way, yall can see it soon

In california the govenor is wants to use a new energy source and he choose to use solar panels. This got me thinking what if we used water imagine a machine that uses the water to create energy but i know its not knew but what if we took that energy along with the energy from sollar panels wouldnt that create more energy by combining these two things we will have more energy and it will work more effeciently like when their is no sun you can use the energy from water wouldnt that be… Continue

I got rid of my car in October 2009. Ever since then I have been living carfree and biking. My roommate has a car, but I use it only rarely. Whenever I can, I bike to meetings, to conferences, to the store, to the farmer's market. Today we went on a bikeride for fun. Continue
It makes me happy that I don't have to pay for gas or car insurance anymore, though of course I give…

Your objective: Design a new way to power something you use every day.
I'd like to change the way vehicle hybrid systems work by using solar, kinetic and battery power to help raise efficiency and reduce the carbon footprint of vehicles. I think there is a lot more that can be done and I hope to developed these technologies in the near future.

This is some kind of crazy idea, and I am not sure it would work. If someone has good knowledge of mechanics and thermodynamics, please read and tell me what you think about that.
I love the idea of perpetual motion. You have to give an initial force, and then a movement is created that will never stops. Real perpetual motion is hard, but an almost perpetual motion would certainly be enough to power a light bulb. We can use for instance the principle of the Orffyreus… Continue

In 1986, approximately 1,800 people were killed when Lake Nyos in Cameroon 'exploded' without warning
, producing a tsunami and a huge cloud of CO2 which asphyxiated people up to 25km away. Many other lakes around the world face a similar threat, and I've been thinking of ways to turn this problem into an opportunity.Exploding lakes

In the near future i want to plan on making more filters for outlets that enable people to save on their electric bill.

My envisioned design would entail a simple 11"x17" solar film that can adhere to a sunny window. This solar source would supply power to a stick that has ports/plug ins for phones/battery powered drills or anything that can plug into an outlet for a recharge.

I'd like to make a treadle-powered washing-machine generator
. I have no idea how much power it would actually produce, but I'd love to be able to at least partially charge my lap-top battery with it. I often sit at the computer most of the day, and treadle-power would give me some much-needed exercise along with meeting at least some of our energy needs at… Continue

i cant take credit for the design or invention of this but my plan is to generate electricity from my solid fuel stove using a thermoelectric generator
on a smaller more immediate scale im buying a candle powered mobile phone charger from tegpower.com

as a martial artist, i tend to practice most days. while this activity provides benefits both physical and spiritual, the energy spent could be stored and used as an energy source. my proposal is a sort of gym filled with devices that capture this energy. the following is an initial list of devices that might prove useful.
1. heavy bags and striking pads that collect energy.
i got this idea from sOccket; if it works for footballs (soccer balls), it could also… Continue

As I ride my bike a lot, I would really like to be able to power small electrical items by electricity created by cycling in someway. A dynamo would be an obvious choice, however they have a bad reputation for increasing resistance. This is not usually desirable unless you're gunning for the large muscular thigh look. Maybe there is some millage in combining cycling with the generating pavement idea already blogged about (Pavegen Systems). The tyres could be fitted with this technology allowing… Continue
