Teen Invents Flashlight That Could Change The World. Ann Makosinski was just another teenager with another science project when she joined her local science fair in Victoria, Canada, last year.

Teen Invents Flashlight That Could Change The World

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. Let’s move on and do something different.” 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.

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. 13-Year-Old Designs Super-Efficient Solar Array Based on the Fibonacci Sequence.

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.

College: Bick starts her freshman year at Princeton University this fall. 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. Utilities Wake Up – Rooftop Solar to Rival Conventional Power. Ecovative Design.

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. 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.

Baseboard and crown moldings that run along exterior walls are also sources of cold air infiltration. 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….
