...This article made me realize once again that all religion is man-made and that astronomy has shown us how insignificant our world?and, indeed, our solar system?is. To make this world a better place (as religion has obviously failed to do), it is time to stop blindly following ancient man-made philosophies and come up with new doctrines for human interaction. Royden Hodgskin Johannesburg...
...down a rear ramp. Even if that one proves to be blocked too, it would still be possible to drive over the bags, though that is a risky move since the fabric may have stiffened in the extreme Martian cold and could damage or interfere with the craft's solar panels. In either event, no one at J.P.L. is remotely calling these problems mission-enders--though no one expects the rover to be able to move off the lander much before the end of this week. "We have some very valuable assets on Mars," says J.P.L. director Charles Elachi...
...also pollute the environment and, many consumers feel, pose unacceptable health risks. Entrepreneurs like Lifton are trying to offer an alternative: clean energy from renewable resources that's plentiful--and portable. Lifton's Medis Technologies, as well as companies like Hydrogenics and Nanosys, is tapping into fuel cells and solar panels to give people power when and where they want it, free from dependence on local grids...
What about that other long-promised alternative-energy source, solar power? Technology Pioneer Nanosys of Palo Alto, Calif., thinks solar's day in the sun has finally arrived. The firm is developing tiny photovoltaic cells that can be incorporated into the fabric of roofing materials to provide power to homes and other types of buildings. Nanosys is combining the science of solar cells with the science of nanotechnology, which manipulates items as small as an atom to do everything from switching electricity to storing data to sensing the movement of a bridge that is beginning to weaken. Thanks to this...
...single square meter of the solar-ready plastic will cost about $100 and last about 20 years, so a complete roof would cost a few thousand dollars. Nanosys' co-founder and head of business development, Stephen Empedocles, says that's a good investment, since the tiles will generate electricity at a cost of about 4¢ per kW-h, well below the 20¢ to $1 for traditional solar panels...
