Pavilion of Great Britain at the world specialized exhibition Astana EXPO 2017 presents non-combustible graphene bulbs. They can serve at least 8 years, Today.kz news portal writes.
"They replaced the tungsten filament with graphene which allows us to save energy. The lamps are absolutely cold, barely warm, they can be touched, these bulbs can serve up to 8 years. They cost about 10 euros on the market, they will become even cheaper afterwards", - said the deputy Commissioner for UK Sara Everett.
Graphene is 200 times stronger than steel, despite the fact that it is a million times thinner than a human hair. In 2004 it was discovered by scientists of the University of Manchester, Andrei Geim and Konstantin Novoselov.
They received the new material by cleaning the graphite to the thinnest layer. The inventors received the Nobel Prize in Physics for their discovery.
Graphene is also used in the creation of aircraft. The material greatly saves energy and fuel. In the nearest future the material will be used in air and water filtration. It is assumed that people will be able to purify seawater with a special graphene tube.
"The tube will completely clean water of salt. As for air cleaning, graphene will collect all the polluted air, put it through a graphene filter where CO2 will remain in graphene and clean air will escape the tube. It will be used anywhere. This is such an innovative material. This is all under development", - said Sarah Everett.
Let us remind that the theme of the British pavilion is "We are Energy". The pavilion is made in the form of a Kazakh yurt.
It should be noted that a number of projects of British innovators entered the top 100 start-ups to be be presented at the exhibition in Astana.
