Multi-Touch with 3D on Nasa World Wind

We developed a multi-touch version of Nasa World Wind on a 7.9 x 6.2 feet tall FTIR (frustrated total internal reflection) based multi-touch wall. This implementation is based on the Nasa World Wind Java SDK and a multi-touch tracking library developed within the Project: Multitouch at the Deutsche Telekom AG Laboratories, which is part of the TU Berlin, Germany. The FTIR multi-touch wall was built from the scratch during a workshop on FTIR multi-touch surfaces in Münster, Germany. All the software is written entirely in Java and the interaction will be hopefully available as an open source project. Please visit the site in a couple of weeks again. Of course, the Java Nasa World Wind SDK and the Deutsche Telekom Labs Multitouch tracking lib are certainly available as open source projects. - Nasa World Wind

Albatron showcases multi-touch LCD panel

In the upcoming Windows 7 operating system, Microsoft will introduce multi-touch finally that basically allows multiple input detection where as XP and Vista is still single.

Albatron had a special driver made for Vista which allows multi-touch and while it is nowhere near fine tuned at this stage, it does work surprisingly well even now.

Albatron’s Optical Touch Panel is 22-inches in size, has a widescreen resolution of 1650 x 1080, has touch accuracy up to 90 frames per second and uses DVI. - TweakTown

Physicists have 'solved' mystery of levitation

Levitation has been elevated from being pure science fiction to science fact, according to a study reported today by physicists.

Beijing saleswoman demonstrates toy which levitates by magnetic force; Physicists have 'solved' mystery of levitation
In theory the discovery could be used to levitate a person

In earlier work the same team of theoretical physicists showed that invisibility cloaks are feasible.

Now, in another report that sounds like it comes out of the pages of a Harry Potter book, the University of St Andrews team has created an 'incredible levitation effects’ by engineering the force of nature which normally causes objects to stick together.

Professor Ulf Leonhardt and Dr Thomas Philbin, from the University of St Andrews in Scotland, have worked out a way of reversing this pheneomenon, known as the Casimir force, so that it repels instead of attracts. - Telegraph.co.uk

Panoramio

We just released a new feature in Panoramio that allows you to browse photos simulating a 3D environment. You can jump from one photo to the closest one, walking virtually around the place or watching the place from many different perspectives. Enjoy the views from the top of Empire State in New York, the last floor of Eiffel Tower or the sights from the Pyramids of Teotihuacan, just by opening the “look around” link under those photos. - Panoramio

What is the Grid?

Well, there's a short answer, and then there's a very long answer.

The short answer is that, whereas the Web is a service for sharing information over the Internet, the Grid is a service for sharing computer power and data storage capacity over the Internet. The Grid goes well beyond simple communication between computers, and aims ultimately to turn the global network of computers into one vast computational resource.

That is the dream. But the reality is that today, the Grid is a "work in progress", with the underlying technology still in a prototype phase, and being developed by hundreds of researchers and software engineers around the world.

The Grid is attracting a lot of interest because its future, even if still uncertain,is potentially revolutionary. - GridCafé

Beaming solar energy down from space

By 2030, India's Planning Commission estimates that the country will have to generate at least 700,000 megawatts of additional power to meet the demands of its expanding economy and growing population.

Much of that electricity will come from coal-fired power plants, like the $4 billion so-called ultra mega complex scheduled to be built south of Tunda Wand, a tiny village near the Gulf of Kutch, an inlet of the Arabian Sea on India's west coast. Dozens of other such projects are already or soon will be under way.

Yet Mehta has another solution for India's chronic electricity shortage, one that does not involve power plants on the ground but instead massive sun-gathering satellites in geosynchronous orbits 22,000 miles in the sky.

The satellites would electromagnetically beam gigawatts of solar energy back to ground-based receivers, where it would then be converted to electricity and transferred to power grids. And because in high Earth orbit, satellites are unaffected by the earth's shadow virtually 365 days a year, the floating power plants could provide round-the-clock clean, renewable electricity. - CNN
