Geoengineering

Geoengineering involves changing our environment to suit human needs better. This article looks at ways geoengineers have thought about reducing global warming by not reducing greenhouse gasses, but by proactively doing something about it. Some pretty far out ideas, such as floating white plastic islands in oceans, space mirrors and lacing the atmosphere with sulphur are brought up. Science is starting to look at these options more seriously and trying to get funds for them at a small scale.

Wireless FM transmitters

This is a device you attach to your mp3 player, either through a port or via the headphone output, which then allows you to select a frequency and transmits the music on FM on that frequency. This allows you to tune your radio to your mp3 player.
In the Netherlands they are finally legal (since about one month) so I decided to get one.
Walking through town I couldn’t find any, except iPod dedicated units (which use the port, so are only iPod compatible). There are 2 Apple versions: one which only works for a dedicated model (eg. only for the nano) and one which works with all iPods except the very first model (and presumably any model they release in the future). These both look slick and work with the ipod seamlessly. Unfortunately they are expensive and iPod only.

If I’d had time I would have gone for the Linex FM transmitter, which connects via the audio jack. It’s bigger than the iPod thing, but it’s around a third of the price.

Computers reading emotions

Our faces express our emotions – apparently there are around 20 key facial movements expressed around 24 facial feature points, which betray our emotions. By scanning these points intelligently, and detecting things such as facial form, computers can read the emotions of those using them.
Ideas posited in the article: websites advertising products directed at the emotional state, detecting boredom or sleepines in cars and helping people with Asperger’s syndrome (difficulty in recognising emotions and facial expressions).

Measuring gravitational waves

2 gravity wave detectors have been switched on, trying to prove and discover waves posited by Einstein as part of his theory of general relativity.

The Americans have a huge isolated lab called LIGO (Laser Interferometer Gravitational-Wave Observatory) run by a few people from the LSU and California Institute of Technology in the middle of Livingston Parish, LA.

Britain and Germany have their Geo 600 Detector in Hannover, run by scientists from Glasgow, Cardiff, Birmingham and Hannover Universities.

Apparently there’s also a similar experiment in Japan, but I couldn’t find the links to that.

Beijing to shoot down rain

Using an arsenal of rockets, artillery and aircraft, China will try to blast the clouds out of the sky, a meteorologist told a Beijing magazine, through a technique which falls under the umbrella of “cloud seeding.”

“We can turn a cloudy day into a dry and sunny one by shooting the clouds less intensively than when we make rain,” head meteorologist Mian Donglian for the Beijing municipal weather bureau told Time Out.

Giant crossbow to shoot man 20 miles into the air

Brian Walker, mad scientist and all around crazy person, plans to shoot himself 20 miles into the air in a homemade rocket launched from the world’s biggest crossbow. The rocket, which has a jet turbine with 1,350 pounds of thrust, will shoot off the track of the giant crossbow shown above, which is equipped with a 24-foot carbon-fiber bowstring. At the peak of his flight he’ll be traveling at a comfortable 10 Gs, and he’ll be wearing a $15,000 surplus Russian space suit to stay safe, because everyone knows the Russians will sell anything for a price.

SSTAR – small, sealed, transportable, autonomous reactor

http://www.newscientist.com/article.ns?id=dn6344

The aim is to create a sealed reactor that can be delivered to a site, left to generate power for up to 30 years, and retrieved when its fuel is spent. The developers claim that no one would be able to remove the fissile material from the reactor because its core would be inside a tamper-proof cask protected by a thicket of alarms

http://www.newscientist.com/article.ns?id=dn6344

The 100 megawatt version is expected to be 15 meters high by 3 meters wide, and weigh 500 tonnes. A 10 megawatt version is expected to weigh less than 200 tonnes. To obtain the desired 30 year life span, the design calls for a moveable neutron reflector to be placed over a column of fuel. The reflector’s slow downward travel over the column would cause the fuel to be burned from the top of the column to the bottom. Because the unit will be sealed, it is expected that a breeder reaction will be used to further extend the life of the fuel.

Futurama will be back

Comedy Central has resurrected the former Fox animated SF series Futurama, ordering 13 episodes to debut in 2008, Variety reported. The deal builds on the cable network’s acquisition of the 72-episode library last fall.

Discussions about a revival of the half-hour show began in earnest earlier this year between Futurama producer 20th Century Fox Television and series creators Matt Groening and David X. Cohen. A sticking point, which has been resolved, had been bringing back the cast, who hadn’t worked on new episodes for the show since it left the air in August 2003.

Voice actors Billy West, Katey Sagal and John DiMaggio are on board for the new episodes, which will continue the story of Fry (West), a pizza delivery boy who was accidentally frozen for 1,000 years and who wakes up in the future.
