Encore Next-gen Simputer  - C/Net  The new machine, called Mobilis, is powered by Intel's XScale PXA255 200/400MHz processor and has 128MB of SDRAM, the company said. It features a 7.4-inch VGA LCD screen, roll-up keyboard, touch screen with stylus input, six-hour battery life and a case that opens up as a desktop stand, Encore said. The machine weighs 750 grams, or about 1.6 pounds. Another version of the device, Mobilis Wireless, comes with an integrated keyboard. A third version, the Sofcomp, is an ultra-compact desktop that works with a regular monitor, the Bangalore-based firm said. The basic Mobilis model will be priced at about 10,000 rupees, or $230, while the version with the TFT screen and integrated keyboard may be priced at about 15,000 rupees, or $347.   
Micromachines to Produce Propellant and Air on Mars - Space.com  Were looking at collecting the carbon dioxide from the Martian atmosphere and breaking it down for [crew needs], said Battelle researcher Kriston BrooksThe goal, Brooks added, is to wrangle microtechnology into a usable system that would generate propellant for astronauts aboard a manned mission to Mars by 2030.  With multiple grooves separated by just 200 microns or so apart, microchannel plates offer improved heat and mass transfer rates.

Experts seek clean, green power  - BBC  Scientists are due to take part in a brainstorming session to seek the future's clean, green energy sources. Energy experts from the world's leading economies will join a two-day workshop at Oxford University to find solutions to the global warming crisis. The scientists will present the fruits of their deliberations to a meeting of the G8 of key industrialised nations in Gleneagles in Scotland in July. Tony Blair has made tackling climate change a priority of his G8 leadership. The conference, at St Anne's College, Oxford, will also involve experts from the G8 states and the five largest developing nations; China, India, Brazil, South Africa and Mexico. The government has pledged to cut carbon emissions (at 1990 levels) by 20% by 2010 and energy firms are being required to source a proportion of the energy they sell from renewable sources. It is hoped the sharing of any technological advances with these states will help reduce any environmental damage associated with their economic development. Mr Blair has said he does not want to "shut the door" to nuclear energy. But in an interview in the Guardian, the government's chief scientist, Sir David King, said reports of an immediate return to nuclear power were premature.
