Wim lives in Massachuesttes and love to swim. Unfortunatly, the swimming season is short, and his pool is shaded most of the day. We decided to build a Solar Pool Heater. We found some 4x8 solar collectors (hot water panels) on craigslist. They a
It exploits magnetic reconnection as a fast, high-power ion heating mechanism; natural plasma self-organization as a robust, stable confinement scheme; and passive magnetic compression at modest ratios to reduce overall engineering complexity.
In 2014, no less an authority than NASA proclaimed in peer-reviewed papers that it was getting mysterious thrust from the EmDrive, a strange, brassy trumpet of a thing that its creators claimed could produce thrust with no propellant.
Germany's Lilium has announced a 7-seat version of its gorgeous eVTOL air taxi, as well as plans to have a commercial operation up and running by 2024. Oh, and like approximately every other eVTOL company, it's headed to the NASDAQ through a SPAC.
On Friday, February 14th, 2020: #Jetman? Vince Reffet took off, headed south towards Jumeirah Beach Residence, building speed and height. In 8 seconds he had reached 100 meters height, in 12 seconds 200m, 19 seconds 500m, and reached 1000m in 30 se
Hundreds of millions of children don't have schools to attend around the world, and Grout feels one of the best ways to solve the problem is by bringing down the construction costs of schoolhouses. The initial pilot Thinking Hut in Madagascar is ex
When augmented reality hits the market at full strength, putting digital overlays over the physical world through transparent glasses, it will intertwine itself deeper into the fabric of your life than any technology that's come before it. AR devices
Much mystery surrounds the biological processes that lead to hair loss in humans, but scientists continue to make discoveries that unravel these secrets and lay the foundation for technologies that may one day treat it.
Instead of building community around a golf course or a pool, they argued for making the farm the focal point and to build tiny houses around it so residents would benefit from fresh produce and views of fields and flowers.
A Domino that won't fall come bumps, tips or wind, the latest off-road camper trailer from Australia's Offline Campers features a unique ruggedized teardrop design that creates a quick sleepover or a full base camp.
It's 2021, and although I thought by now there would be flying cars, cities on the moon and the ability to teleport from my bed to my couch instead of walking, I guess I'll settle for a jet pack, or as DARPA is calling it, a "Portable Personal
Discussion of reviving the Passamaquoddy Tidal Power Project has surfaced every few years, with studies undertaken and debates renewed. Each time, most people agree that the engineering plan is sound: the project could be built and it would work. Oth
Wind turbines are a good source of renewable energy, but they typically incorporate heavy-duty towers – thus making them permanent structures. The new Wind Catcher, however, is designed to be lightweight and portable.
