Teen Invents Flashlight That Could Change The World | This Could Be Big. Ann Makosinski was just another teenager with another science project when she joined her local science fair in Victoria, Canada, last year. Her invention, a flashlight that is powered solely from hand heat, took second place at the competition. Ann, 16, and her parents, both of whom are HAM radio operators and like to fiddle with electronics, were satisfied with that result. “It’s a very simple project,” said Arthur Makosinski, Ann’s father. “It has four electrical components. But had Ann left her project in Victoria, situated just 25 miles north of Washington State, the world may have missed out on a light source that doesn’t use batteries, solar power or wind energy. Think about that for a moment: a flashlight that shines for as long as you hold onto it.

Stunningly, no one on record has thought to use thermoelectric technology to power a flashlight. Two years ago, Ann, who is half-Filipino, was corresponding with a friend of hers in the Philippines who didn’t have electricity. The Genius Who Plays For A Living. Just before he was old enough to vote but after he'd begun a doctorate in computer science, Erik Demaine arrived in New York City for the annual OrigamiUSA convention. He'd recently taken an interest in the hobby because he thought the math behind it might make for a compelling dissertation topic.

Walking the aisles of the convention, Demaine saw the usual paper artistry—delicate insects, puffed-up bunnies—but he also learned of more elaborate forms, such as a three-car model locomotive crafted from a single sheet of paper. That train, like many intricate works of origami, sprang from a basic folding pattern called the box pleat.

Developed in the mid-1960s, the box pleat is a grid of vertical and horizontal creases combined with some well-placed diagonals. A Swiss physicist named Emmanuel Mooser popularized the pattern when he used it to create what's now known as Mooser's Train, one of the great achievements in origami. 13-Year-Old Designs Super-Efficient Solar Array Based on the Fibonacci Sequence. Plenty of us head into the woods to find inspiration. Aidan Dwyer, 13, went to the woods and had a eureka moment that could be a major breakthrough in solar panel design. On a bleak winter hiking trip to the Catskill Mountains, the 7th-grader from New York noticed a pattern among tree branches, and determined (as naturalist Charles Bonnet did in 1754) that the pattern represented the Fibonacci sequence of numbers.

Aidan wondered why, and figured it had something to do with photosynthesis. In a pretty innovative experiment, this intrepid young scientist set about duplicating an oak tree, comparing its sunlight-capturing abilities to a traditional rooftop solar panel array. First he determined the ratios representing the spiral pattern of the leaves and branches on an oak tree, using a cylindrical double-protractor tool of his own design. You can read Aidan's award-winning essay here, which walks you through his experiment design and his results. High School Inventors 2011. In between pep rallies and history tests, these 10 brainy students are refining cancer treatments, cleaning up car exhaust systems, and improving communication between humans and robots.

High School: Millburn High School, Millburn, N.J.Invention: Smartphone water-quality tester When Alison Dana Bick was in middle school, a downpour swamped the streets of her hometown and flooded its well. Public officials warned that flooding might have carried sewage into the water supply. "My friend called to ask if there was a way to check the safety of the tap water," Bick says. When a Google search revealed that there wasn't any fast and easy household test, she decided to create one.

Four years later, she completed work on a cellphone application that determines the concentration of bacteria in a photographed sample of water. College: Bick starts her freshman year at Princeton University this fall. Ryan Erickson may live on a high desert mesa, but he has big plans for the ocean. This Amazing Invention Is Saving Countless Lives After Typhoon Haiyan. When natural disaster strikes, one of the first and most significant casualties is clean water: Humans can only go so long without liquids; as days pass without functioning infrastructure, bacteria spread and multiply, as does the threat of disease. Large aid organizations’ answer has often been to send 747s stocked with cases of bottled water to the affected areas.

But drop-offs like that can cost hundreds of thousands of dollars and leave behind a stream of plastic waste. Enter WaterStep, a Kentucky-based aid organization that says it’s come up with a clever solution: the M-100 Chlorine Generator, a football-size water filter that allows survivors to produce up to 10,000 gallons of potable water per day. Sixty of the devices are being used in the Philippines, says WaterStep CEO Mark Hogg. The generator’s byproducts—chlorine and sodium hydroxide—are valuable resources for locals, says Hogg.

Go Green || Sustainable Design - Buildipedia.com™ Upgrade your home’s insulation and air-seal gaps and cracks sooner rather than later.

This is one home improvement that will pay for itself relatively quickly and then continue to generate savings for as long as you live in your home. Even if a full upgrade is not in your budget this year, you can tackle several low- or no-cost improvements right now. Here are 10 tips to keep your home comfortable this winter. 1. Use the passive solar heat that’s available to you. If you have a sunroom or enclosed porch with a southern exposure, it can collect a great deal of heat. Use a small fan or natural convection to move air through a doorway from solar-warmed rooms to adjacent interior spaces. 2. In winter, a surprising amount of cold air can leak into your house around window and door openings, due largely to the fact that the framed (or rough) opening of a window or door is bigger than actual size of the window or door. 3. 4. 5. 6. 7. 8. 9. 10. THIS NEW GREEN HOUSE" Bees and Permaculture Article and Film- Brigit Strawbridge.

We are very proud to have a guest post this week by Brigit Strawbridge on Bees and Permaculture…. First up we have a film of a great talk that Brigit did about bees at the Sunrise Off Grid festival in 2011, followed by a article by Brigit on Bees and Permaculture, a great resource for all bee lovers out there. A quick note, Brigit contacted me to say that at the start of the film she says, there are 200,000 types of bees, but actually it’s 20,000, but it would be great if there was 200,000 Bees and permaculture: I have to admit to being just a little obsessed with bees. They have fascinated and enchanted me since my childhood, but it is only since the decline of the honeybee began to make headlines a few years ago that I fully realised the magnitude of their importance as pollinators – and how much I had always taken them for granted.

The Seemingly Simple GO Home is a LEED Platinum House That Packs a Green Energy Punch. Photo credit: Trent Bell The bright red GO Home in Belfast, Maine was recently selected as the LEED for Homes Project of the Year for 2011. Completed by GO Logic, the seemingly simple house packs an impressive renewable energy punch and is a LEED Platinum and Passive House certified residence. Because it is a passive house, the home’s owners will see a 90% reduction in their heating bill, resulting in a cool $300 dollars per year for space heating, while enjoying all the comforts of the super insulated building shell during the winter months.

With a roof clad in solar panels, The GO Home is also net zero, creating all the energy on site that it needs to provide heat, hot water and electricity for the home owners who will not see an energy bill for the next 25 years. + GO Logic Homes.
