Space Elevator Update

Recently I found a nice round-up of the state of building a tower into orbit, the only sane way to get stuff up there. Here are a few highlights:
  • a space elevator could be built on the Moon using existing materials
  • LiftPort has been resurrected and is working on this right now
  • carbon nanotubes could be the "diamond thread" that A C Clarke described in his novels
  • International Academy of Astronautics says that a space elevator "seems feasible"

Art Tech

Years ago, I saw a documentary by artist David Hockney that argued that the Dutch Masters achieved their extraordinary photo-realism with aid from secret lens-based devices.  Now a new film is being released with a similar theory, in which an American inventor with no art training attempts to recreate a Vermeer painting using advanced-for-its-time lens technology.  Although art experts prefer the "he was just a genius" idea, this seems very convincing as a way to make photos before photography was invented.  What is fascinating is the lengths people had to go for something we all take for granted now.

More Old Computer News

The National Museum of Computing has a new exhibit, a 1960s ICT 1301 otherwise known as "Flossie". Weighing in at over 5 tons, this one only has few tubes but is full of early germanium transistors, along with apparatus for punched cards, tape storage and printing.  It's claim to fame is being the first mass-produced business computer, and as one of the curators says, this meant that no special wiring/ducting was needed in the office where it was installed.  The once cutting-edge looks were apparently shown off in a Bond film, and I also suspect a similar device was the titular star of the second sequel of a certain other spy film series.

Walrus

Having been reading a bit of Lovecraft recently, I was amused by this silly story from El Reg about a walrus buried in a London graveyard.  Rather than a mad scientist's "walrusoid abomination", it was probably just a bit of medical research. The best bit is at the end when a researcher confesses that it's fairly mysterious:
"...we drew a blank.  There was a reference to Prince Albert riding on the back of a giant tortoise, but unfortunately it wasn’t relevant."
As a commenter says, this statement should be quoted whenever anyone references the results of any research.

Clone

The Altair 8800 was an early home computer which came out in 1975.  You programmed it by flipping switches and watching the lights blink.  The picture is actually an Altair 8800 Clone; it turns out that original ones are now super expensive so a guy made a version with modern components.  What used to be a box stuffed with circuit boards is now empty - the work is done by a chip the size of a penny. It's a bit like old tube radios...

Badgers

Cannot resist a badgers/technology story; North Yorkshire residents will have to wait for their superfast broadband connection while the engineers laying the cable figure out if they have to re-route around protected badger setts.  Slashdot has the best headline so far: "Badgers Block British Broadband Buildout".  It is apparently the job of a "badger expert" to decide if there are badgers actually living there. Perhaps the badgers are all getting ready for a parade?
