A high-tech running shoe is worthless if it is two sizes too small and gives the runner blisters and pressure sores. The same goes for prosthetic limbs, according to David Sengeh, a 26-year-old graduate student from Sierra Leone who was honored Wednesday with an award for his work on an innovative socket that makes prosthetic limbs more comfortable and thus functional for amputees.

“Whether you have a robotic ankle or a wooden peg, if the socket is not functional you wouldn’t use your leg,” he told NBC News, explaining why he has focused his energy on developing next-generation sockets, or interfaces, for prostheses.

Algae converted to crude oil in less than an hour, energy department says

The day when planes, trucks and cars are commonly revved up on pond scum may be on the near horizon thanks to a technological advance that continuously turns a stream of concentrated algae into bio-crude oil. From green goo to crude takes less than an hour.

The goo contains about 10 percent to 20 percent algae by weight. The rest is water. This mixture is piped into a high-tech pressure cooker where temperatures hover around 660 degrees Fahrenheit and pressures of 3,000 pounds per square inch in order to keep the mixture in a liquid phase.

Students, prompted by massacre, design emergency lock to thwart shooters

The killing spree at Sandy Hook Elementary School in suburban Connecticut last December sent a chill across America. If the unthinkable happened there, it could happen anywhere. The concern prompted a team of high school students in Washington, D.C., to design an inexpensive and effective emergency door-locking mechanism to prevent active shooters from entering their classrooms.

Like many schools around the country, the doors at Benjamin Banneker Academic High School lack classroom-side locks, a building code regulation leftover from a time when fire was the biggest threat to student safety. Unlockable doors mean students can escape a burning classroom quickly. Yet in today’s world, students also worry about intruders coming into their classrooms and firing bullets.

Girl power! 9th grade girls developing electricity-generating desks

A team of 9th grade girls is developing a system of interconnected desks that turns the nervous foot-tapping energy of school kids into electricity to power study lights, laptops and fans. The young students aim to bring the desks to school children in Africa.

“In order to get a good education, one of the basic foundations is electricity,” Rose DelleFave, the team leader at Providence Day School in Charlotte, N.C., told NBC News. “So we decided it would be good to start there and give them that basic tool.”

Noise-cancelling window sensor helps you enjoy this silence amid cacophony

The cacophony of any city’s hammering jack hammers, beeping buses, and relentlessly yacking citizens can make anyone long for an oasis of silence. Enter the Sono, a futuristic noise-canceling gadget that sticks on the window and turns even the noisiest of rooms into a chill place to think. The pebble-shaped device, a finalist in a prestigious design competition, serves as a reminder of the power of quiet.

“From time to time, I just want to escape the noisy world for a while to reset my mind,” Rudolf Stefanich, an industrial designer who created the Sono device while a graduate student at the University of Vienna in Austria, told NBC News in an email. The gadget was selected as a top-20 finalist for the annual James Dyson Award. The famous designer will hand pick and announce a winner on Nov. 7.

Pummeled kite surfer dreams up new way to harvest wave energy

Publication: NBC News   Date: October 11, 2013   View Article

Samuel Etherington first hit the waves with a board and kite in hand, the waves hit back with a bruising vengeance. But in learning to harness their power for his kitesurfing adrenaline rush, he found inspiration to design a next-generation wave energy harvester. The contraption scored him a coveted finalist spot in an engineering design competition and could serve as a viable alternative source of energy to boot.

“The waves would just roll and smash over you and then you would tumble and try to get back up on the board and try again and try again,” the mechanical design student at Brunel University near London told NBC News about his early days kitesurfing. “That then really physically hit home. There is a lot of power to be had here.”

11-year-old designs a better sandbag, named ‘America’s Top Young Scientist’

Publication: NBC News   Date: October 10, 2013   View Article

An 11-year-old boy from Florida has designed a new kind of sandbag to better protect life and property from the ravages of saltwater floods. His invention took top honors at a science fair this week, earning him a $25,000 check and a trip to Costa Rica.

“Living in Florida, I’m keenly aware of hurricanes and saltwater flooding,” the Discovery Education 3M Young Scientist Challenge grand prize winner Peyton Robertson, who is a sixth grader at the Pine Crest School in Ft. Lauderdale, Fla., told NBC News.
