When people think about building things with carbon nanotubes or with carbon nanotube enhanced materials they need to know that there is not much production of carbon nanotubes. There is less than 1000 tons/year of carbon nanotubes being produced and most of that is in a form that is like an unsorted powder. The material …
The environment group WWF has a report which says that $17 trillion must be spent on renewable energy between now and 2050 to avoid temperatures rising by 2 degrees celsius and irreversible climate change. Previously the World Wide Fund for Nature funded a climate scorecard with rigged numbers WWF does not consider nuclear power to …
Carnival of space 125 is up at orbiting frog. Superconducting magnets are reaching 30-35 tesla now and appear on track to reach 60-70 tesla. This will enable the superconducting magnets to test a possible superpropulsion theory where the magnets are used to shunt into hyperdrive. The basic concept is this: according to the paper’s authors …
North Dakota oil production has reached new highs and the two month lag in monthly statistics will likely show about 250,000 barrels of oil per day in October or November. The latest monthly statistics are 231,252 barrels of oil per day (bopd) for August 2009. Brigham Exploration Co. on Friday said that one of its …
Prof. Leonid Shvartsman and Prof. Boris Laikhtman of the university’s Racah Institute of Physics have invented a novel design of TeraHertz-ray (T-ray) lasers. They said the novel device will have 400 times higher “gain” (a measure of power) than that of the only coherent T-ray sources existing today, called THzQuantum cascade lasers. “The novel method …
After seven years of theoretical work and raising money, five months of design, five months of construction and assembly, and a week of testing, LPP (Lawrenceville Plasma Physics) now has a functioning dense plasma focus, Focus-Fusion-1. The first shot, using helium as the fill gas, was achieved at 5:29 PM today, Oct.15, and the first …
United Nations health agency said that more than 4,735 deaths attributable to H1N1 had been reported, and that influenza activity in the northern hemisphere was much higher than usual. WHO spokesman Gregory Hartl said it was too soon to draw any conclusions from the death toll as experts needed to monitor a full year of …
Iraq is close to finalising deals at three of its largest oilfields that could nearly triple output and make it the world’s number three producer after Russia and Saudi Arabia. Two deals have been sent to Iraq’s cabinet for ratification. It is unclear when the cabinet will ratify them. There are no guarantees that the …

New Scientist reports that Technical University of Delft researchers have found that carefully focus light arriving on an exposed memory chip, the charge stored in every cell corresponds to whether that cell is in a light or dark area. The chip is in effect storing a digital image. This technique can increase the pixel resolution …
