Another zero-emissions powerplant emerges – the Dearman Engine runs on liquid air

A new zero-emissions engine capable of competing commercially with hydrogen fuel cells and battery electric systems appeared on the radar yesterday when respected British engineering consultancy Ricardo validated Dearman engine technology and its commercial potential. The Dearman engine operates by injecting cryogenic (liquid) air into ambient heat inside the engine to produce high pressure gas that drives the engine – the exhaust emits cold air. It’s cheaper to build than battery electric or fuel cell technology, with excellent energy density, fast refuelling and no range anxiety. http://www.gizmag.com/dearman-zero-emissions-engine/21201/

Thinking Aloud: The #1 Usability Tool

Simple usability tests where users think out loud are cheap, robust, flexible, and easy to learn. Thinking aloud should be the first tool in your UX toolbox, even though it entails some risks and doesn’t solve all
problems. http://www.useit.com/alertbox/thinking-aloud-tests.html

Defend Your Rights To Non-Drug Alternatives

Herbs and vitamins prevent diseases on which drug companies would like a monopoly so the drug companies want to ban access to herbs and vitamins.
If you take vitamins and wish to continue doing so,
If you take herbal teas and wish to continue to do so,
If you feel freedom of choice in health care is important,
If you feel you know what is best for your body better than a drug company schill in a parliament half a planet away,
Please take the time to send a petition protesting the application of codex alimentarius to prevent access to herbs and vitamins.
