The “‘Lobster Eye’ X-ray focusing optics” device is a hand-held optical device able to see through walls, even shipping containers. Their target market is law enforcement. Great. I love how they list “contraband hidden behind walls” as a use for this device.
“Anything behind walls” sounds too invasive…
Physicists at the Bhavnagar University in Gujarat, India, have discovered a way to trap, store, and release laser light in a fluid on command. The fluid operates at room temperature, and is controlled with magnetic fields.
[The scientists] coated micron-size magnetite spheres with oleic acid and dispersed them through a ferrofluid, which is a suspension of much smaller magnetic nanoparticles (in this case held in kerosene). When an external magnetic field was applied to the fluid, which was held in a glass cell, laser light passing through the medium was trapped inside. Photons escaped when the field was switched off.
Could this be a solution for an optical storage medium, to complement an optical processor?
“SCiB” touted to be safer than today’s Lithium Ion, lasts 10 years, charges in minutes (@ up to 50 amps).
1/3 pound (150 gram) cell is
- the size of a mobile phone
- provides 4.2 aH @ 2.4 volts. (devices)
4.4 pound (2 kg) cell is
- the size of a small paperback novel
- provides 42 aH @ 24 volts. (vehicles)
If they are able to deliver in mass production at a profit, this could be a major new development in both transportation and electronic devices.
