Lockheed Martin has been getting its feet wet in the renewable energy game for some time. In the 1970s it helped build the world’s first successful floating Ocean Thermal Energy Conversion (OTEC) system that generated net power, and in 2009 it was awarded a contract to develop an  OTEC pilot plant in Hawaii . That project has apparently been canceled but the company has now shifted its OTEC sights westward by teaming up with Hong Kong-based Reignwood Group to co-develop a pilot plant that will be built off the coast of southern China. OTEC uses the natural difference in temperatures between the cool deep water and warm surface water to produce electricity. There are different cycle types of OTEC systems, but the prototype plant is likely to be a closed-cycle system. This sees warm surface seawater pumped through a heat exchanger to vaporize a fluid with a low boiling point, such as ammonia. This expanding vapor is used to drive a turbine to generate electricity with cold seawater...

The architects responsible for the Panorama House have made a staircase of epic proportions that acts as a functional centerpiece of the house. The staircase serves as a multifunctional hub, not only providing a way to get from downstairs A to upstairs B, but forming a central element of the house's library, cinema, and play area. Designed by Moon Hoon, the Panorama House is located in Chungcheongbuk-do, South Korea, and while the whole building is magnificent, it's the staircase that really stands out. It is gargantuan, with the stairs themselves representing just a small part of the structure (as can be seen in the gallery). Those heading down to the lower floors can take the stairs or use the slide instead, with kids and adults alike invited to experience the latter. The individual steps provide storage space for books, while the space underneath the staircase itself is used as an office, with plenty of room for a desk and chair. Last but not least in this staircase's ...

Since humans are responsible for much of the damage to coral reefs, it makes sense that we should try and help repair them. That’s exactly what a team from the Herriot-Watt University’s Centre for Marine Biodiversity and Biotechnology is attempting to do with the development of underwater “ coralbots .” Now anyone can add their support to this worthy effort with the launch of a Kickstarter campaign that will help make the robots a reality. The research team has already built a couple of prototype coralbots that can be equipped with onboard camera, computer, and flexible arms and grippers. These would come together to allow the robot to reattach healthy pieces of coral back onto a reef to help speed up the healing process. This time-consuming task is currently performed by scuba divers – or not at all. It also makes repairing reefs at greater depths difficult or impossible. The team’s plan is to develop a swarm of robots that would autonomously navigate across a damaged coral ...

When you have plenty of bicycle to work with, such as is the case with a mountain bike, it’s not such a big deal to design it with front and rear suspension. When the bicycle in question is a diminutive folding city bike, however, it gets a bit trickier. That’s why UK industrial designer Sam Pearce has created Loopwheels. Instead of relying on a suspension fork and rear shock, it lets the bike’s 20-inch wheels absorb the bumps. Each wheel incorporates a regular hub, with a hub brake and hub gearing. Instead of spokes, however, three looped carbon composite springs run from the hub to the rim. Whenever the wheel hits a bump in the road, the energy is absorbed by those springs. This causes the hub to momentarily dip down within the wheel by up to 45 millimeters, so it’s actually a bit off-center until the springs flex back into their regular state. For this reason, the wheels will only work on bikes that already have sufficient space between the fork/frame and the tire – otherwise th...
