solar cooker, washing nuts so the house becomes a "green"
Here are the seven most ingenious ideas to combine domestic utility and minimum environmental impact of SARA Ficocelli
home also means saving and clean energy production. Throughout the world, is a hive of competitions, and then ideas. We selected seven highly innovative.

The solar cooker. To put the sun in a box he had never thought anyone. There could Jon Bohmer inventing Kyoto Box, the solar cooker for which he won first prize in the 2009 Climate Change Challenge, a competition for the invention more "Echo" organized by Forum for the future. The stove (cost of project: $ 5) is small, it produces heat and solar energy will be very helpful to those two billion people live on the edge of survival and have the sun as the only heritage. Allow them to disinfect water and make it drinkable, warm at night and cook.

tissue-light. Renewable energy leader also in the Portable Light Project, created by MIT (Massachusetts Institute of Technology) with an idea of \u200b\u200bthe scientist Sheila Kennedy. Again the principle is simple, flexible solar panels based on the integration into fabrics and curtains to create free energy and free. The pilot project, developed with input from architects, anthropologists, engineers and doctors, was created to meet the needs of the indigenous population of the Mexican Sierra Madre, which has no access to electricity. The "Solar Fabric" is made from semiconductors that absorb the sunlight convert it into electricity. The end result is a lightweight, portable, and soft, capable of storing the sun's rays and light return, becoming a sort of nomadic lamp.

The bike rechargeable batteries. And after the solar energy between the stove and tissues, could not miss that for the means of transport. The system on two wheels Ubicycle, Design Continuum created by the agency, will travelers to Montreal (the first city where the bicycles will be distributed), a new way to walk the city, using a bike which, if necessary, by solar energy, scooters become greener. To recharge just place them to the racks. Fine invention, but how many chains in Italy, we should build in order to prevent someone steal?

boats to thermal energy. Dell'universitàdi Berkeley scientists have also developed water machines, from small, solar-powered "direct", able to exploit the surface tension of liquids. These tiny "boats" are made of plastics and strips of carbon nanostructures: when the sun's rays are concentrated on the device, the nanotubes are heated by releasing thermal energy also to water molecules that surround them and thus causing a decrease in surface tension. In the absence of obstacles, the object is directed towards a heated area to the most moving on the surface tension of the liquid. In short, the ship sails without throwing a drop of pollution at sea. The printer

coffee. Among the renewable raw materials, however, is not only the sun. Even the coffee remnants can be recycled and become such as ink to print documents: this is the idea behind the futuristic Printer RITES, a label printer with a kind of glass in which to pay the remains of drinks Dark (tea or coffee). E 'was conceived by Korean Jeon Ju Hwan, who has entered the last edition of the Greener Gadgets Competition. The glass must be moved to the right and left hand and the drink is deposited on the sheet, saving the environment, in a long-term perspective, tons of chemicals are not biodegradable.

The washer nuts. Same goes for the E-Wash Washing Machine, created by the Hungarian Levente Szabo, winner of the fifth edition of the Electrolux Design Lab 07. This small and compact appliance has the capacity to load and spin equal to those of modern equipment, only instead of the classic powder detergents using the "nuts cleansing" of the tree Sapindus mukorossi, cleaner whose power has been known for millennia in India and Nepal. The merit is all the shells, rich in saponin, a substance present in small percentage in industrial products but also that in this case is used pure, it melts on contact with water and functions as a normal detergent, disinfectant, moreover, also. Drinking water

wind. Thanks for renewables is also possible to get potable water from the oceans without using electricity. The project developed by the Universityof Technology, Delft, The Netherlands, has succeeded in developing a windmill reverse osmosis, which pumps salt water using wind power and port from the sea to osmosis membrane, a pressure of about 60 bar. The salt content in the solution is then issued, making it possible to obtain fresh water. The mill is capable of producing five to 10 cubic meters of water per day, depending on the capacity and speed of wind available, and allow tanks to conserve water for five days in situations of extreme drought or shortage wind. The alternatives to help the planet then there: just have the urge to go and look.

change the borders with Switzerland

lines established in 1861 will be modified based on the movement of glaciers on the peaks. The Parliament will authorize a joint committee to define the new frontier of Vincenzo Nigro
For millennia Nature has imposed his authority over a man. Then the man started to change the nature, to require that its reasons for helping to change the world. Moving the course of rivers, mountains, puncturing, removing or building entire islands. Every now and then nature takes its revenge, and forces the man to change many things. Even the borders between states.

But as for changing the boundaries need to change the treaties, now change the nature of the Laws of the States, those enacted by parliaments.

Italy and Switzerland are preparing to change their boundaries because global warming is melting glaciers. And at high altitude, if they change the profiles of the glaciers, change the lines dividing a State other. Everyone knows that glaciers are retreating, are reduced: alarm, however, must be serious even if the bureaucracies Swiss and Italian governments are asking to amend the Treaties establishing the boundaries. It means that the joint technical committee of the Military Geographic Institute of Florence and "Swisstopo," the federal agency map of Bern, pointed out that the reduction of glaciers is so substantial that the legal boundaries no longer correspond to reality. And that is why the Italian Parliament on the proposal of Minister of Foreign Affairs Franco Frattini, is preparing to authorize the Joint Committee to do its job of grinding. "Once the boundaries established themselves with weapons, now with the experts," said the rapporteur of the design ADNKRONOS Franco Narducci of the law, a member of the Democratic Party.

The head of Italian technicians is General Carlo Colella, commander of the IGM in Florence. "In the Seventies I changed another border between Italy and Switzerland, to Brogeda," said the officer, "but it was a change due to man, to build the motorway Lugano-Como was diverted the course of a stream" . Now the glaciers are to impose the changes: "On the Plateau Rosa del Monte Cervino, Monte Rosa, the Piz Bernina ice has decreased a lot." If the boundary is the watershed of the glacier when the ice comes down the watershed on the ground moves for tens of meters. "With the Swiss borders were never changed, virtually are those recognized by the Italian Constitution of 1861, "says General Colella:" Now sembratutto moving, everything could be different. "
