Solar sail progress is difficult to assess

Different materials for solar sails with wide variation in capability are all in development. The lighter the sail then the faster it will accelerate. This link has a table which shows the different speeds possible with different accelerations. The carbon nanotube sail has the highest potential. 1 square kilometer 30 kg or 0.03 grams per …

Robotic exoskeleton replaces muscle work

A robotic exoskeleton controlled by the wearer’s own nervous system could help users regain limb function, which is encouraging news for people with partial nervous system impairment, say University of Michigan researchers. The ankle exoskeleton developed at U-M was worn by healthy subjects to measure how the device affected ankle function. The U-M team has …

Discovery Channels view of 2057

Discovery channel has a series on the future of 2057 They are way to conservative on what they are projecting. The chat transcript with series host futurist Michio Kaku shows that he is not up to date on the latest technologies. He thinks that the most powerful quantum computer calculation is 3*5=15. This was the …

Natural Resource Defence council on air pollution

As many as 64,000 premature deaths occur each year from cardiopulmonary causes attributable to particulate air pollution, according to NRDC estimates. Most particulate emissions result from burning fossil fuels — coal, oil, diesel, gasoline — or wood. Old coal-fired power plants, industrial boilers, diesel and gas-powered vehicles and wood stoves are some of the worst …

Bacteria resistant artificial skin

Skin cells genetically engineered to be resistant to bacteria could reduce infections and improve chances of survival among burn victims. A patient’s skin cells, genetically modified and grown in a test tube, could provide the next generation of artificial skin. As a first step in creating such replacement skin, scientists in Cincinnati have engineered bacteria-resistant …

Plasmoid thruster could lead to fusion

Researchers at the University of Alabama in Huntsville’s (UAH) Propulsion Research Center are working on the Plasmoid Thruster Experiment (PTX). It is a stepping stone to a highly efficient propulsion concept which could ultimately change how we travel in space. Larger, more powerful versions can produce fusion for both power and space propulsion. The purpose …

World Future Society predictions are wrong

The World Future Society makes forecasts which show that the forecasters do not seem to really understand some of the technology that they are forecasting. Forecast #2: The era of the Cyborg is at hand. Researchers in Israel have fashioned a “bio-computer” using the DNA of living cells instead of silicon chips. This development may …

Nanowelding nano-electronics

Researchers in Switzerland have developed a new technique for joining nanotubes. One technique, called “nanorobotic” spot welding, uses molten copper to join up objects in the same way that a human electrician might use solder. They position 50-nanometre-wide carbon nanotube filled with copper inside a nanorobotic manipulator, and run a small voltage through it to …
