Uranium from seawater idea boosted with shrimp shells

BBC News – A report at the 244th meeting of the American Chemical Society described a new technique using uranium-absorbing mats made from discarded shrimp shells. The oceans hold billions of tonnes of uranium at tiny concentrations, but extracting it remains uneconomical. Although these trials proved the principle of uranium extraction from seawater, the cost …

SpaceX flight opens door for U.S. military payloads

The recent successful Spacex test flight means they can start working off a $1.6 billion contract with NASA to fly cargo to the space station. It also clears a key hurdle for SpaceX to compete for Department of Defense business as well, which would mean launching military satellites. Flying three times successfully was among the …

Friedlander’s Idea For A Nuclear Hopper

What if the most economical use of a nuclear powered spacecraft is not direct to escape but just to get above the atmosphere? The economics of nuclear thermal rockets A guest article by Joseph Friedlander Brian Wang has covered many nuclear thermal rocket ideas from gas-core reactors to NERVA and DUMBO to Liberty Ship and …

Making Stargates: The Physics of Traversable Absurdly Benign Wormholes

Extremely short throat “absurdly benign” wormholes enabling near instantaneous travel to arbitrarily remote locations in both space and time – stargates – have long been a staple of science fiction. The physical requirements for the production of such devices were worked out by Morris and Thorne in 1988. They approached the issue of rapid spacetime …

Carbon nanotube muscles generate giant twist for novel motors

Researchers announced new artificial muscles that twist like the trunk of an elephant, but provide a thousand times higher rotation per length. These muscles, based on carbon nanotubes yarns, accelerate a 2000 times heavier paddle up to 590 revolutions per minute in 1.2 seconds, and then reverse this rotation when the applied voltage is changed. …
