Fuligin technology on the way

This is the message as the crawl holds it, before anything here touched it. What the conversation shows has been through ingest: transfer encodings decoded, attachments dropped, quote markers repaired, and the archiver’s ? resolved into quotation marks and dashes. Those repairs are judgements and some of them are wrong, which is what this page is for. Email addresses are obscured here as they are everywhere else on the site, so it is before our repairs rather than byte for byte.

'Anti-laser' Traps All Incoming Light"

"Call it the anti-laser. Instead of amplifying light, it would soak it 
up completely, leaving utter darkness."
[snip]
"A paper-thin slice of silicon would normally absorb about 20 per cent 
of the incoming light, but the team showed that in this set-up it would 
cancel nearly all of the light at 945 nanometres, in the near infrared. 
So far the effect exists only on paper, but team member Douglas Stone 
says "ongoing experiments are extremely promising, and I have total 
confidence it can be realised". The energy from the cancelled beams is 
converted into heat, but if it could somehow be turned into current, the 
effect could allow pulses in fibre-optic cables to be converted with 
high efficiency into electrical signals."
