Reduce drag for faster and more efficient ships

The New Scientist, examines the efforts to reduce ship drag using tiny bubbles, slippery polymers and trapped sheets of air. As a ship moves through water it encounters three types of drag: wave drag, pressure drag and frictional drag. Wave resistance is mainly a problem at high speed, and can be minimised with a carefully …

Swarmanoids

Swarmanoids are a follow up to swarmbots Will initially have eye-bots, hand-bots and foot-bots Swarm robotics is inspired by the social insect metaphor, and emphasises aspects such as decentralisation of control, limited communication abilities among robots, use of local information, emergence of global behaviour, and robustness. Most current studies in swarm robotic systems have focused …

Slingatron and magnetic launchers

The US army has some small funding for a Slingatron. Initial studies have demonstrated the fundamental feasibility of the Slingatron concept. This program will explore the concept’s bounding limits and seek to develop uses for the technology within those limits. Included in this program will be studies of the key technologies that will allow the …

Cooling technology and ultimate limits of computing

In Dec, 2005, Fujitsu announced that they were able to connect carbon nanotube bumps to the miniature electrode of a high power transistor. Carbon nanotubes have thermal conductivity of 1400W/(m-K) – a level much higher than that of metal(4), and because it is possible to connect carbon nanotube-based bumps very near to the heat-generating miniature …
