If you are interested in “free energy” and clean energy technologies, you should pay attention to graphene, an emerging material that has some very interesting characteristics. Some of graphene’s interesting characteristics are its thickness, electrical conductivity, and amazing energy transferring ability.
What is graphene?
Graphene is the thinnest material known to mainstream scientists. To be more specific, it is about one million times thinner than paper. Because graphene is so thin, some scientists consider it to be two dimensional. At the atomic level, graphene is made of a single layer of carbon atoms. These carbon atoms are bonded together in a repeating pattern that is shaped like a hexagon.
Even though graphene is super thin, as a material, it is phenomenally strong. This special material is so strong that it is 200 times stronger than steel. Furthermore, graphene conducts electricity and heat better than any material known to mainstream scientists.
Another cool feature of graphene is that it is very flexible. Because of its flexibility, it can be twisted and curved to a certain extent without breaking. This characteristic of graphene allows it to be used as a material to cover all types of surface.
Graphene and fuel cells
Graphene’s ability to conduct electricity beyond ordinary methods is one of the reasons why it is being studied as a material to be used in clean energy and “free energy” applications. According to scientists, graphene allows electrons, which are the particles that make up electricity, to move 200 times faster than silicon.

Fuel cells, used in some modern cars, react oxygen and hydrogen fuel together, converting chemical energy into electricity and producing only water.
But a major problem is that the fuels leak across the existing proton membranes, “poisoning” the process and reducing the cells’ efficiency — something Geim says could be overcome with graphene.
The team also found that graphene membranes could be used to extract hydrogen from the atmosphere, suggesting the possibility of combining them with fuel cells to make mobile electric generators powered by nothing more than the tiny amounts of hydrogen in the air.
“Essentially, you pump your fuel from the atmosphere and get electricity out of it,” says Geim.
Other uses for graphene
Due to graphene’s unique characteristics, it can be used in many different fields, including but not limited to biological engineering, quantum computers, nanotechnology, alternative energy, and space travel. It can also be used to improve the performance of thousands of products, such as cell phones, TVs, computers, sports equipment, and cars.
