SUNSTOP writes to tell us that a relatively unknown Maryland scientist has proposed a public patent that he claims could combat global warming. The proposed plan would require massive amounts of water to be sprayed into the air in an effort to bolster the earth's existing air conditioning system. "First, the sprayed droplets would transform to water vapor, a change that absorbs thermal energy near ground level; then the rising vapor would condense into sunlight-reflecting clouds and cooling rain, releasing much of the stored energy into space in the form of infrared radiation. Kenneth Caldeira, a climate scientist for the Carnegie Institution's Department of Global Ecology at Stanford University whose computer simulation of Ace's invention suggests it would significantly cool the planet. The simulated evaporation of about one-half inch of additional water everywhere in the world produced immediate planetary cooling effects that were projected to reach nearly 1 degree Fahrenheit within 20 or 30 years, Caldeira said."

mallumax writes "Obama has launched Change.gov. According to the site 'Change.gov provides resources to better understand the transition process and the decisions being made as part of it. It also offers an opportunity to be heard about the challenges our country faces and your ideas for tackling them. The Obama Administration will reflect an essential lesson from the success of the Obama campaign: that people united around a common purpose can achieve great things.' The site is extensive and contains Obama's agenda for economy and education among many others. They first define the problem and then lay out the plan. Everything is in simple English without a trace of Washington-speak. The site also has details about the transition. According to many sources, Obama's transition efforts started months ago. The copyright for the content is held by 'Obama-Biden Transition Project, a 501c(4) organization'."

An anonymous reader writes "For those with a stake in the opposition of Jim Prentice's C-61, the Canadian DMCA, this previous week's election results will be displeasing. The Conservative Party, which promised to reintroduce the DMCA if elected, gained 19 seats this election, mostly at the expense of the flagging liberal party, a mere 12 short of a majority government. The increase in Conservative representation, as well as the relatively low profile of this issue amidst other, more pressing concerns, increases the likelihood that the son of C-61 will come to fruition. On a positive note, the number of MPs supporting Geist's copyright pledge has increased to 34. Given the Conservative Party's historic disregard of public opinion, however, the efforts of the copyright-pledge MPs will have to rally the full opposition across three major parties in order to defeat the bill. A mere 12 MPs now stand between the Canadian public and the MAFIAA's hungry maw."

theodp writes "Is Google preparing to launch its own Navy? In its just-published application for a patent on the Water-Based Data Center, Google envisions a world where 'computing centers are located on a ship or ships, which are then anchored in a water body from which energy from natural motion of the water may be captured, and turned into electricity and/or pumping power for cooling pumps to carry heat away from computers in the data center.' And you thought The Onion was joking when it reported on Google's Fleet of Naval Warships!"

katicli writes "Geohashing, an obscure xkcd pastime which involves going to random coordinates generated by md5 hashing, the date, and the opening status of the stock market, appears to have just gotten far more interesting. The official wiki reports a warning for other geohashers intending to go to the spot designated for June 14th in the San Francisco area, as several avid fans of xkcd were met by an angry rancher and firearms."

PRB_Ohio takes us to Space.com for a story about NASA's plutonium shortage, and how it may affect future missions to the far reaches of the solar system. The U.S. hasn't produced plutonium since 1988, instead preferring to purchase it from Russia. We discussed the U.S. government's plans to resume production in 2005, but those plans ended up being shelved. If NASA is unable to find an additional source, it could limit missions that take spacecraft too far from the Sun. Quoting: "Alan Stern, NASA associate administrator for science, ... said he believed the United States had sufficient plutonium-238 on hand or on order to fuel next year's Mars Science Lab, an outer planets flagship mission targeted for 2017 and a Discovery-class mission slated to fly a couple years earlier to test a more efficient radioisotope power system NASA and the Energy Department have in development. To help ensure there is enough plutonium-238 for those missions, NASA notified scientists in January that its next New Frontiers solicitation, due out in June, will seek only missions that do not require a nuclear power source."

An anonymous reader writes "Google is reportedly looking into investing in or buying a company called Space Data, which provides wireless voice and data services to remote areas with a fleet of weather balloons fitted with transceivers." My mind is sorta tripping over how something like this could work, but I gotta admit that the idea is really cool.

Ant writes "MSN UK has up an article that looks into the 'downfall' of the joystick: 'Sometimes technology disappears completely, but often it just fades into the background — still existing, still being used and sold and, occasionally, desired, but probably looking wistfully back on past glories. Which neatly described the joystick's steady slide away from its role as THE gaming peripheral to a fondly remembered also ran. But the joystick's tale is a long and convoluted one — and it is worth looking back into its often mysterious and ill-studied history before explaining why it will rise from the ashes like the mythical phoenix.'

An anonymous reader writes "Animals use pheromones to attract each other for sex, and warn each other of danger. Now, Wired reports, military researchers are working to harness the 'human fear' pheromone to create a scent of terror. The pheromone could lead to smell-based terrorist sensors, and new weapons that rely on 'contagious' stress."

wintersynth brings us a story about a group of enthusiasts who made a catapult out of a 2,800lb industrial robot arm. They used it to launch bowling balls, fireballs, and cans of beer toward a stationary target, and they controlled the catapult's aim with a graphical UI on a laptop. "I wanted to be able to control the rotation of the robot so we could aim the robot from the laptop, but I quickly realized that since the desert is so flat, we could do some basic ranging on the target too. I also wanted the targeting to be overlaid in 3d over a photograph of the target area. The software needed to control the robot like an MMO or RTS game. I suspect that video games, in general, have some of the most optimal control interfaces. I wanted to try a control scheme similar to the area effect spell targeting in World of Warcraft."
