[ Filed under Science or in the New Materials category ] When we think of peak oil and how best to cut down on our fossil fuel consumption, most of us only think of transportation alternatives. But the fact is that producing plastics also uses up quite a lot of oil. Could finding an alternative to plastic be a solution to our dwindling oil supply? Researchers at the University of Tokyo think its a step in the right direction, and they think that their new invention could be just the alternative material we need. Takuzo Aida and his team created a hydrogel thats strong enough to support itself on a self-standing bridge (see above), flexible and maybe best of all self-healing. The material is composed of around 95 percent water mixed with small amounts of microscopic clay disks, sodium polyacrylate, and a special molecule called G3 binder. The gel is very easily formed and is ready to use within three minutes. The strength and elasticity of the material depend on how much of each component ingredient is included in the mix. Due to its high water content and ability to heal itself, the new material could be highly useful in tissue engineering and prosthetics. As of now, the components used are still derived from fossil fuels, but hopefully non-petroleum sources could be found to make the compound more environmentally friendly while maintaining its beneficial qualities.

It's also about increasing the efficiency of existing machines. One of the simplest (yet most challenging) ways to do that is to decrease the friction created by machines. Friction decreases energy efficiency and makes parts wear out quickly, meaning that replacement parts have to be manufactured and installed...

http://feedproxy.google.com/~r/Gajitz/~3/EIpOuSrcego/?utm_source=feed... [ Filed under Gadgets or in the Various Gizmos category ] Not everyone can be a gourmet chef, but we all still need to eat, right? What that means for most culinary-challenged people is lots and lost of fast food. But in the future, maybe youll be able to give the drive-through a rest and get a healthy, delicious meal in your kitchen with just a few button presses. No, were not predicting pizza delivery were talking about high-tech food printers. Just like 3D printers, which have quickly gone from sci-fi to reality and now to almost mundane, the 3D food printer may soon become an everyday sight in kitchens. There are actually several designs being developed right now, but this one, called Cornucopia, is from MIT grad students Marcelo Coehlo and Amit Zoran. The contraption works by storing and cooling a variety of ingredients in the containers on top. When the user initiates meal-making, the machine goes to work combining ingredients _layer_ by _layer_, then heating or cooling them in the chamber below. According to its creators, the machine can produce textures and flavors that wouldnt be possible through traditional cooking. A big part of the design is the health factor. Ultimately, the user controls the quality and origins of the ingredients but doesnt have to learn the fine art of preparing the food. Users can customize foods and entire meals _base_d on parameters like calories, carbohydrates or fat content. For those of us who want to eat healthier but are a bit lost in the kitchen, being able to effortlessly prepare a nutritious meal could be life-changing. The designers have included a user-friendly interface that has intuitive controls and allows for a large degree of customization. The machine is even smart enough to know when a particular ingredient is running low and automatically order more. If all of this sounds a little far-fetched right now, maybe its because this is an entirely new direction for food preparation that hasnt yet been explored, either in real life or even in science fiction. But its not only possible it actually seems likely, given the success of 3D _object_ printers.
