The Sietch Blog » Watercone – An Ingenious Way To Turn Salt Water Into Fresh Water The Watercone is an ingenious device that can take salty water and turn it into fresh water using only the power of the sun. The nice thing about this device is it is bone simple, uses the sun instead of fossil fuel, and is cheap to make and easy to use. The Watercone is surprisingly a cone, that you place over a pan of salty water (or over a marsh, or any damp ground) leave it out in the sun, water evaporates, the condensation trickles down the side of the cone, at the end of the day you flip it over, remove the cap at the top and drink the water. This device has the potential to really do a lot of good for a lot of people.

Everything I Thought I Knew About Velociraptors Was a Lie Today I found out everything you probably think you know about Velociraptors is a lie. Now to be fair, everything I “knew” about Velociraptors came from the Jurassic Park movies and so I shouldn’t really be surprised it was all wrong. So if, like me, you thought that Velociraptors were slightly bigger than a human; reptilian looking; hunted in packs; were found in what is now the United States; and were ridiculously intelligent. Well, literally none of that is true. Velociraptors were actually only about the size of a domesticated Turkey, being only about 3 feet tall and 6 feet long, with most of the length coming from the tail and weighing in at around 20-30 pounds full grown. More than that, they also looked somewhat like a Turkey as well, but with a long tail obviously.

Solar car The Sunswift solar car eVe, which holds an FIA world record and in 2016 will be Australia's first road legal solar car A solar car is a solar vehicle used for land transport. Solar cars only run on solar power from the sun. They are very stable and can come in different sizes. To keep the car running smoothly, the driver must keep an eye on these gauges to spot possible problems.

C:\IMAGES\OMNIPAGE\DATA\hm2.htm In collaboration with Norman Rostoker from UC at Irvine, we have designed a novel type of fusion reactor, the Colliding Beam Fusion Reactor (CBFR). It uses protons (p) and boron-11 (11B) for fuel. Fusion reactions produce only three helium-4 (4He) nuclei, and nearly 9 million eV energy. Exploring Tomorrow Whether you are baking them at home or buying them from the store, cupcakes seem to be a welcomed treat by many. With the various combination of flavours and the creative designs that bakers have presented the world with, the cupcake trend continues to rise. But how else can a cupcake company innovate to meet the demands of their customers, around the clock?

ChemEngineering - Wind profile power law The wind profile power law is a relationship between the wind speed at one height and the wind speed at another height. The power law is often used in wind power assessments1, 2 where wind speeds at the height of a wind turbine (about 50 meters or more) must be estimated from near surface wind observations (about 10 meters), or where wind speed data at various heights must be adjusted to a standard height3 prior to use. Wind profiles are generated and used in a number of atmospheric pollution dispersion models.4 The wind profile of the atmospheric boundary layer (from the ground surface to around a height of 2000 meters) is generally logarithmic in nature and is best approximated using the log wind profile equation that accounts for surface roughness and atmospheric stability.

Windbelt Micro-wind, 10 Times Cheaper Wind Energy!! [Run time: 2:05 min] I hope you enjoy this short video of Shawn Frayne, a young inventor that has created this device to generate, on the micro-scale, energy for LED lights and radios in developing countries. This is the first approach that uses aeroelastic flutter to create super cheap electricity. We’re talking about changing the way wind energy is harvested and captured. Frayne won a 2007 Breakthrough Award from Popular Mechanics, and he deserves it. This incredible technology is 10-30 times more efficient than the best micro-turbines. So, Frayne hopes to fund third-world distribution of the Windbelt through sales in first-world applications.

Incredible Space Pics from ISS by NASA astronaut Wheelock Go Discovery! It was October 23, 2007 at 11:40am EST when I had my first ride to space on Discovery. She’s beautiful… just sad that this will be her last voyage. Wind power Wind power is the conversion of wind energy into a useful form of energy, such as using wind turbines to make electrical power, windmills for mechanical power, windpumps for water pumping or drainage, or sails to propel ships. Large wind farms consist of hundreds of individual wind turbines which are connected to the electric power transmission network. For new constructions, onshore wind is an inexpensive source of electricity, competitive with or in many places cheaper than fossil fuel plants.[1][2] Small onshore wind farms provide electricity to isolated locations.

How this 12inch miracle tube could halve heating bills Last updated at 21:09 15 September 2007 It sounds too good to be true - not to mention the fact that it violates almost every known law of physics. But British scientists claim they have invented a revolutionary device that seems to 'create' energy from virtually nothing. Their so-called thermal energy cell could soon be fitted into ordinary homes, halving domestic heating bills and making a major contribution towards cutting carbon emissions. Scroll down for more... Even the makers of the device are at a loss to explain exactly how it works - but sceptical independent scientists carried out their own tests and discovered that the 12in x 2in tube really does produce far more heat energy than the electrical energy put in.

4 Rare Earth Elements That Will Only Get More Important Sir William Crookes, a 19th century British chemist, once wrote that, "rare earth elements perplex us in our researches, baffle us in our speculations and haunt us in our very dreams." These weren't easy elements to isolate or to understand, and so there was a very long lag time between the discovery of the rare earths, and the discovery of practical uses for them. It didn't help that individual rare earth elements don't occur by their lonesome—they travel in packs. To get one, you have to mine all of them. At first, industry didn't even bother to separate out individual rare earths, instead using them in a blended alloy called mischmetal. This provided the first commercial applications, says Karl Gschneidner, senior metallurgist at the Department of Energy's Ames Laboratory.
