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 ...""

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.

Submitted by

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."

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."

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.""

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.""

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.""

It was intended to deliver a spherical capsule, called Fotino, attached to the end of the tether back to Earth — a relatively simple and cheap technology that could be used in the future to retrieve bulkier cargoes from space.""

Submitted by
Tjeerd
Tjeerd writes "Amazing British invention creates MORE energy than you put into it — and could soon be warming your home. It sounds too good to be true — not to mention the fact that it violates almost every known law of physics. But British scientists claim they have invented a revolutionary device that seems to 'create' energy from virtually nothing. Their so-called thermal energy cell could soon be fitted into ordinary homes, halving domestic heating bills and making a major contribution towards cutting carbon emissions. The project, which has cost the company £1.4million, has the backing of the Department of Trade and Industry, which is keen to help poorer families without traditional central heating or who cannot afford rocketing fuel bills."

Tjeerd writes "A lightweight solar-powered plane has smashed the official world record for the longest-duration unmanned flight. UK defence firm Qinetiq, which built the Zephyr unmanned aerial vehicle, said it flew for 54 hours during tests. The researchers believe it is the first time a solar-powered craft has flown under its own power through two nights. The previous unmanned endurance record was set in 2001 by a jet-powered US Air Force Global Hawk surveillance aircraft which flew for more than 30 hours."

Steorn, an Irish technology development company, will publicly demonstrate a real-life application of its Orbo free energy technology for the first time. The demonstration will take place in the Kinetica Museum gallery, London UK on Wednesday 4th July. People around the world will be able to watch the exhibit via a live web stream. The real-time streaming of the Orbo free energy technology demonstration can be accessed via steorn.com/orbo/demo from 6pm Eastern Time (ET) today.
