Ducks for Desalination

ducky thingWater is becoming more precious round the world, yet the oceans are filled with the wet. If someone found a way to turn salty water into potable water easily and cheaply there would be a lot less thirsty people out there.

Stephen Salter at Edinburgh University has found a way to use the power of waves to remove salt from water. Desalination takes a lot of energy and by using waves, the energy cost obviously is a lot lower. The system is shaped like a duck and works by popping in the water and using that force to steam water for clean, drinkable goodness.

THe inventor also invented the first system to use wave energy for electric power and he was inspired to make this system from a trip to India.
“I visited India just after they had missed two monsoons and water was becoming a worry,” Salter told New Scientist. “I thought that using wave power for desalination would be a neat idea.”

Gender Bender in NYC

New York City is moving ahead with a proposed change in the rules of birth certificates. After much campaigning from activists who argue that gender is not merely physical, NYC will soon start letting people change their gender on their birth certificates (NYT link, to bypass registration try bugmenot). Reader mkb also points out this article .

Once it’s approved people will no longer have to have sex-change surgery to proclaim what gender they are.

“If approved, the new rule would put New York at the forefront of efforts to redefine gender. A handful of states do not require surgery for such birth certificate changes, but in some of those cases patients are still not allowed to make the change without showing a physiological shift to the opposite gender.”

Thanks, mkb!

AIDS Fighting AIDS

A new, but very small, study has found that AIDS can be used to fight AIDS like a vaccine. The US experimenters used gene therapy techniques to tackle AIDS in the five test patients. The results are promising and “hint at something much more,” according to Dr. Carl June of the University of Pennsylvania School of Medicine.

The article points out in the second paragraph that AIDS has no cure, something that many articles fail to do when talking about proposed new ‘cures’ for HIV/AIDS. So that acknowledgment is good, because there is (for some bizarre reason) people who think that HIV/AIDS can be cured. This article talks about fighting AIDS, and in doing so also fights ignorance.

Build Your Own Solar iPod Charger

For those of you with iPods, you may want to ensure that you never have to worry about the battery dying. This is a neat use of small scale solar power, it’s a homemade solar panel that attached to a backpack using velcro that connects to an iPod.

The instructions are easy to follow, and one step is sipping on some coffee (which is hopefully fair trade and organic). If I had an iPod I would try making this, not just for cheap power, but for solar style.

The UK, so advanced

In another move that proves its not all about the GDP, the UK is moving forward to regulating energy effeciency. The Department for Environment, Food and Rural Affairs has been working on replacing “ineffecient” goods. This would set minimium standards for 14 energy using products, including commercial lighting. With a competative advantage such as this, the UK stands to make real progress in the environmental, financial and social fields.
