ARCA Space Corporation has announced its linear aerospike engine is ready to start ground tests. Designed to power the world’s first operational Single-Stage-To-Orbit (SSTO) satellite launcher, the engine took only 60 days to complete from when fabrication began.
The new cooling system, which uses no electricity, could make future air conditioning and refrigeration cheaper by sending heat up into space.
Carbon dioxide–splitting techniques could store excess electricity from renewable sources
Nanotube weave can light up an LED when pulled
The green-tech guru is backing an energy storage breakthrough that could power the future.
Today’s soldiers need to carry pounds of electronic equipment, and that much again in batteries to power it all. Now a chance discovery might help lighten the load. The US Army Research Laboratory has created an aluminum-based powder that produces a high amount of energy when placed in water.
Batteries powered by bacteria could prove highly useful in providing spurts of electricity where it isn’t readily available. The latest breakthrough in this area calls only on bodily fluids, and was able to power an LED light using a single drop of spit.
Eco Marine Power is preparing to put its rigid solar energy sails through their paces next year. The EnergySail from EMP can harness the power of the wind and sun at the same time, for high-efficiency transport on the high seas.
If there’s a bottleneck in today’s smartphones and mobile devices generally, it’s battery life – or, rather, the lack of it – but a new innovation from researchers in the US could mean an end to constantly staring at that sad-looking little red…
Last year, Lithium Cycles launched a 1,000-watt e-bike on Kickstarter that married funky retro styling with modern motorized tech. The Super 73 is now up for pre-order as the Scout, a slightly different beast to the crowdfunded model, and one that could be had for less than a thousand bucks..
