More than half of all personal aircraft accidents occur during takeoffs or landings. That’s why inventor JoeBen Bevirt is intent on making runways obsolete.
Now he created a personal electric airplane called 'S2' that takes off vertically, like a helicopter, and flies aerodynamically, like an airplane.
No full-scale prototype exists yet, but his team have built about two dozen 10-pound models to demonstrate their concept works.
Supercomputer simulations of a full-scale, 1,700-pound S2 suggest it could fly two people about 200 miles (New York City to Boston) in an hour on 50 kilowatt-hours of electricity, or roughly equivalent to 1.5 gallons of fuel used by a typical two seated airplane ― which would make the new aircraft about five times more efficient.
Michael Dortch was building video surveillance trailers for industrial parks. At that time, his clients wanted to see intruders in the dark from all angles, but such coverage required up to seven thermal infrared cameras and cost more than $100,000.
So Dortch and a colleague spent four years developing a cheaper, more capable alternative. Their system provides 360-degree infrared coverage that can spot people, fires, vehicles, and more.
The heart of the invention is a single, spinning thermal sensor. Onboard processors constantly stitch images together for a refreshing panoramic video feed, and intelligent software finds threats. It will cost about $16,000 and should be ready for its debut later this year.
Yet while helmets can reduce the risk of head injuries by 85 percent, only few bike share riders wearing helmets. 92% of bike scheme cyclists don't wear a helmet. A traditional helmet’s bulk is a major turnoff for casual riders.
So Jeff Woolf invented a model that’s as handy as a bike itself. Called the Morpher, his creation is a full-scale helmet that folds to the size of a textbook.
The helmet collapses to just 1.4 inches thick. The thickest model collapses to 2.5 inches. It’s compact enough to fit in a laptop bag.
Is it safe enough? The latest prototype has passed European-grade safety tests at a factory.
Each thud of a hiker’s heel releases enough energy to illuminate a lightbulb. Rather than waste that power, an engineer Matt Stanton created a shoe insole that stores it as electricity.
Instead of using piezoelectric and other inefficient, bulky methods, the pair shrunk down components similar to those found in hand-cranked flashlights. The result is a near standard？size removable insole that weighs less than five ounces, including a battery pack, and USB.
The current version requires a lengthy 15-mile walk to charge a smartphone. But the company is working toward a design that can charge an iPhone after less than five miles of hiking.
When bullets or shrapnel strike a soldier, standard first aid calls for stuffing gauze as deep as five inches into a wound and applying pressure for three minutes.
But Military doctors estimate that, during the most violent years of the wars in Afghanistan and Iraq, blood loss killed about 90 percent of the wounded.
To save more lives, RevMedx has created a pocket-sized device called XStat: a faster, more effective way to plug wounds.
The polycarbonate syringe slides deep into a wound. When a user pushes down on the handle, it deposits dozens of pill-size sponges that expand to stem bleeding. Meanwhile, a substance in the sponges fights infection while clotting blood.
The team is currently seeking FDA approval.
