I do think that the 21st century will have some sort of "green revolution", it's just a name which everyone quickly understands. It's not a perfect term. I myself don't own - and never had - a car and do everything by bike or by using public transport, so that already helps a little bit in saving energy I think. Furthermore I was also thinking about production/transport/etc. of the solar panels which might also cost quite some energy. So in the end a solar energy panel wouldn't differ that much from electricity coming from the grid. The idea was/is to solar recharge my Asus EEE (~25 watts) while I am not at home/working. And in the evening use the netbook for a few hours. Total energy usage in combination with my LCD monitor - which would use the grid - would be about ~90 watts. In ideal conditions. I should make a calculcation to see the real difference it makes compared to just using normal electricity from the grid. But besides that, I think that solarpanels still need to become more efficient. I read already a few times about new technologies discovered, but the hyperlinks I gave are the only systems I know of. And which might be not worth it perhaps. But hey, if *everyone* keeps waiting, current solar companies won't earn enough money to start making more/better solar panels. It would be ideal if I could just put my mobile at my desktop and it recharges via the solarpanel integrated in the backside. And while for other people a car is a toy - which doesn't really help the environment - I think playing with (portable) solar energy is not that bad at all.

Is time slowing down?->

Submitted by
Tjeerd
Tjeerd writes ""When astronomers observed a decade ago that supernovae are apparently spreading apart faster as the universe ages, they assumed that something must be causing the expansion of the universe to speed up. But so far, nobody has been able to explain where the "dark energy" causing this acceleration comes from. Now José Senovilla at the University of the Basque Country in Bilbao, Spain, and his colleagues have a radical answer — we are fooled into thinking that the expansion of the universe is accelerating, because time itself is slowing down. Senovilla's work, which will appear in Physical Review D, is based on speculative string theory models in which our universe is confined to the surface ...""

Police force keeps supervision from zeppelins->

Submitted by

Tjeerd writes "The police force will use in the coming spring in the Region Rijnmond/Rotterdam, zeppelins, both and manned unmanned. It concerns a test, which must expel if the quiet air ships can take over tasks of noisy and also with regard to emission less environment-friendly police force helicopters. Zeppelins equipped with cameras will be used at events where many witnesses on to descend, as football game, Red Bull Air-race, the Bavaria city race and the world port days.

Reading paralysed man's mind->

Submitted by
Tjeerd
Tjeerd writes "Electrodes have been implanted in the brain of Eric Ramsay, who has been "locked in" — conscious but paralysed — since a car crash eight years ago. These have been recording pulses in areas of the brain involved in speech. Now, New Scientist magazine reports, they are to use the signals he generates to drive speech software. Although the data is still being analysed, researchers at Boston University believe they can correctly identify the sound Mr Ramsay's brain is imagining some 80% of the time."

Within two years robot with artificial cerebellum->

Submitted by
Tjeerd
Tjeerd writes "Sensopac brings together electronic engineers, physicists and neuroscientists from a range of universities including Edinburgh, Israel and Paris with groups such as the German Aerospace Centre. It has 6.5m euros of funding from the European Commission. Its target is to incorporate the cerebellum into a robot designed by the German Aerospace Centre in two year's time. The work at the University of Granada is concentrating on the design of microchips that incorporate a full neuronal system, emulating the way the cerebellum interacts with the human nervous system."

Start-up warms up personal robots->

Submitted by
Tjeerd
Tjeerd writes ""A Silicon Valley start-up is developing a hardware and software development platform for personal-assistant robots, autonomous boats and unmanned cars. The privately funded company, quietly started almost a year ago by eGroups founder and veteran Google architect Scott Hassan, plans to make its robotics software open source. That way, it hopes to draw a community of developers to build applications in these respective fields.""

Brain-computer-interface for Second Life->

Submitted by
Tjeerd
Tjeerd writes ""A research team led by professor Jun'ichi Ushiba of the Keio University Biomedical Engineering Laboratory has developed a BCI system that lets the user walk an avatar through the streets of Second Life while relying solely on the power of thought. To control the avatar on screen, the user simply thinks about moving various body parts — the avatar walks forward when the user thinks about moving his/her own feet, and it turns right and left when the user imagines moving his/her right and left arms.""

Dark Matter Of The Universe Has A Long Lifetime->

Submitted by
Tjeerd
Tjeerd writes ""New research from the Niels Bohr Institute presents new information that adds another piece of knowledge to the jigsaw puzzle of the dark mystery of the universe — dark matter. Signe Riemer-Sørensen has analysed the one of the two clusters of galaxies that are in the process of colliding. The analyses show that it is a very heavy cluster with many galaxies, and measurement of the gravitation show that there is a very big amount of dark matter, up to 85 per cent of the collective mass. However, no x-ray of any consequence was measured.""
