Laser Particle Acceleration: Status and Perspectives for Nuclear Physics (12 pages) High power short-pulse lasers with peak powers presently reaching Terawatts and even Petawatt levels routinely reach focal intensities of 10^18–10^21 W/cm2. These lasers are able to produce a variety of secondary radiation, from relativistic electrons and multi-MeV/nucleon ions to high energetic X-rays and gamma-rays. …
James Cameron will direct Avatar 2 for 2014 and Avatar 3 for 2015 (shot back to back and in 3D of course) The first Avatar grossed $2.8 billion, so the new movies will be the top priority for 20th Century Fox. The third Chris Nolan Batman movie will be called the Dark Knight Rises. It …
By using magnetic links between capsules, researchers hope to build a snake-like robot that can self-assemble inside a patient’s stomach.Credit: ETH Zurich There were two advances that accelerate the integration of humans with electronic and robotic devices: 1. Modules that self-assemble inside the stomach could perform more-sophisticated diagnosis and treatment. A collaboration of researchers from …
A simplified picture of the electric sail. An actual system would have 50 to 100 or more 20 kilometer wires. 100 kg spaceships could be accelerated to final speeds of 40-100 km/second. [Further refinement can enable a 800km/s top speed – the top solar wind speed] This site has identified the solar electric sail as …
The Transition “Personal Air Vehicle” is expected to be released in late 2009 and has just shown its operational prototype. The estimated purchase price is $148,000. Owners will drive the car from their garage to an airport where they will then be able to fly within a range of 100 to 500 miles (800 km). …
