Free power- How to convert a washing machine into a water powered generator

25

A step by step guide showing how to convert a smartdrive washing machine into a pelton wheel dc generator making 780 watts, the power is fed into a small battery bank & inverter – generating enough power to live off the grid. All you need is a head of water. I am using water from my stream to spin the turbine.

AquaStar Plus! UV Water Treatment Device
UV in a bottle
AquaStar was designed to be sold to a high-end market to fund a lower-cost application in the developing world. The more expensive AquaStar Plus! is used in the harshest environments by travelers, military personnel, and rescue workers. Unsafe water is placed in the bottle and exposed to UV-C light, which damages the DNA and RNA in the pathogens, rendering them non-infective. AquaStar Flow Through treats water in larger batches. A small water-purification service can generate income while helping out the community.

Design for the Other 90%
February 17 – May 29, 2009
"Of the world’s 6.5 billion people, 90 percent have little or no access to most of the products and services many of us take for granted. In fact, nearly half do not have reliable access to food, clean water, healthcare, education, affordable transportation, or shelter. The exhibition Design for the Other 90% features more than 30 projects that reflect a growing movement among designers, engineers, and social entrepreneurs to create low-cost solutions for everyday problems. Through local and global partnerships, individuals and organizations are finding unique ways to address the basic challenges of survival and progress faced by the world’s poor.

Design for the Other 90% showcases designs that incorporate new and traditional materials, and abandoned and emerging technologies to solve myriad problems—from cleaner-burning sugarcane charcoal to a solar-rechargeable battery for a hearing aid, from a portable water-purification straw to a low-cost laptop. By understanding the available resources and tools as well as the lives and needs of their potential users, these designers create simple, pragmatic objects and ingenious, adaptive systems that can help transform lives and communities.

Narcoleptic Powerbook
Laptop Batteries

Image by Eastenhuh
So… many may remember a time last year when my Powerbook G4 crapped out on me due to a faulty temp sensor under the trackpad on the top case. It gave my laptop a perpetual case of narcolepsy… thinking that it was 130 degrees C and falling into deep sleeps at random points, unable to be woken unless I pulled out the battery and the power adaptor. It was indeed hellish.

"In Haiti, the production of wood charcoal, the primary source of cooking fuel, contributes to severe deforestation and environmental degradation. More than 90% of Haiti is now deforested. Many children die of respiratory infections from breathing indoor cooking fumes. Sugarcane charcoal was developed as an alternative to wood charcoal. Dried bagasse, the waste product from sugarcane processing, is burned in a simple kiln, carbonized, mixed with a binder, and compacted using a press to produce sugarcane charcoal briquettes, which burn as well as wood charcoal. Other agricultural waste materials such as corn cobs are being explored as other “food for fuel” alternatives. Corn cobs do not need further processing after burning, eliminating the need for binders and briquetting equipment and significantly reducing the cost of charcoal production."

These women were standing at the southeast corner of Broadway & 73rd street, at the entrance to Verdi Park.

********************

This is part of an evolving photo-project, which will probably continue throughout the summer of 2008, and perhaps beyond: a random collection of "interesting" people in a broad stretch of the Upper West Side of Manhattan — between 72nd Street and 104th Street, especially along Broadway and Amsterdam Avenue.

I don’t like to intrude on people’s privacy, so I normally use a telephoto lens in order to photograph them while they’re still 50-100 feet away from me; but that means I have to continue focusing my attention on the people and activities half a block away, rather than on what’s right in front of me.

I’ve also learned that, in many cases, the opportunities for an interesting picture are very fleeting — literally a matter of a couple of seconds, before the person(s) in question move on, turn away, or stop doing whatever was interesting. So I’ve learned to keep the camera switched on (which contradicts my traditional urge to conserve battery power), and not worry so much about zooming in for a perfectly-framed picture … after all, once the digital image is uploaded to my computer, it’s pretty trivial to crop out the parts unrelated to the main subject.

For the most part, I’ve deliberately avoided photographing bums, drunks, homeless people, and crazy people. There are a few of them around, and they would certainly create some dramatic pictures; but they generally don’t want to be photographed, and I don’t want to feel like I’m taking advantage of them. I’m still looking for opportunities to take some "sympathetic" pictures of such people, which might inspire others to reach out and help them. We’ll see how it goes …

The only other thing I’ve noticed, thus far, is that while there are lots of interesting people to photograph, there are far, far, *far* more people who are *not* so interesting. They’re probably fine people, and they might even be more interesting than the ones I’ve photographed … but there was just nothing memorable about them.

My initial focus was on the two blonde women in the middle, because I thought the combination of their hair, sunglasses, and water bottles made an interesting composition. But when I saw the result, I was also intrigued by the way they were flanked by the other women around them…

Energy Hog

This hotel has those handy-but-annoying places to park your card key just inside the door. Putting the card in the slot turns on all power to the room. A pain in the butt if, while you’re gone, you actually want to leave your computer on for a download, or have some batteries charging. A folded business card does the trick. (a single layer is too thin for this one, for some reason).

You can see the vents. In typical Thinkpad fashion, the computer doesn’t get hot. Just warm. Lots of vents on this with the main vents being on the sides. Blurry shot but the Thinkpad has the usual drain holes if you spill water on the super excellent keyboard.

Oh, yeah, it has the thicker battery… windows was telling me 5 hours of run time with the screen brightness turned up.

Sorry for the crappy shots! I took them quickly without checking. And the lens distortion is really visible there. The computer isn’t bent like that.

Disposable lithium battery strip reacting in water

25

Disposable lithium camera batteries (and other batteries) contain a strip of lithium metal which can be extracted and dropped in water for a fun reaction. Be sure to do this in a well ventilated area, and stand far away. Given a large enough piece of lithium, it will begin to react violently and eventually “explode”, as seen in the video.
