Teleportation Achieved Over 10 Miles

teleportation_0129

Quantum teleportation won’t be transporting Kirk and his Away Team to the surface of some distant planet anytime soon, but it has seriously practical applications to communications.

Quantum teleportation has achieved a new milestone or, should we say, a new ten-milestone: scientists have recently had success teleporting information between photons over a free space distance of nearly ten miles, an unprecedented length. The researchers who have accomplished this feat note that this brings us closer to communicating information without needing a traditional signal, and that the ten miles they have reached could span the distance between the surface of the earth and space.

Physicist Discovers How to Teleport Energy

First, they teleported photons, then atoms and ions. Now one physicist has worked out how to do it with energy, a technique that has profound implications for the future of physics.

In 1993, Charlie Bennett at IBM’s Watson Research Center in New York State and a few pals showed how to transmit quantum information from one point in space to another without traversing the intervening space…

Ceramatec have created the disk, which can hold up to 20-kilowatt hours

A small disc could be the solution for the efficient and cheap storage of the sun’s energy.  A Utah-based company has found a new way to store solar energy – in a small ceramic disk which can store more power for less. Researchers at Ceramatec have created the disk, which can hold up to 20-kilowatt hours, enough to power an entire house for a large portion of the day.

Batteries Built By Viruses

Power From an Unlikely Source

Researchers have genetically engineered biological viruses to form the anode and cathode of a battery. MIT researcher Angela Belcher and her colleagues manipulated the genes of a harmless virus so that the bug coats itself in tiny iron phosphate particles and connects to highly-conductive carbon nanotubes. From Science News…

Platinum-Free Fuel Cells Eliminates Need For Expensive Catalysts

Platinum-Free Fuel Cells Eliminates Need For Expensive Catalysts 

 A new polymer, shown in powdered form, can be used to make stable fuel-cell membranes that conduct negatively charged ions.

Fuel cells are, in principle, the most efficient way to convert hydrogen fuel into electricity. But they require expensive catalysts such as platinum to split hydrogen into ions and electrical current. Cheaper metals simply can’t withstand the harsh acidic environment of the fuel cell. Now researchers in China have developed a fuel cell that uses a new membrane material to operate in alkaline conditions, eliminating the need for an expensive catalyst. The power output of the new prototype, which uses nickel as a catalyst, is still relatively low, but it provides a first demonstration of a potentially much less expensive fuel cell.
