Graphene
the Foundation of the
New Generation of Learning Computers

by Dr. Maria Kuman

Book cover 'Quantum Mind & Quantum Growth - Ways of Spiritual Growth'This is my dissertation on graphene published as a book. Why did I decide to publish it as a book? It is because graphene, which is one layer of graphite, recently became a very hot topic.

Recently, the first computer with graphene chips was created at the University of California at Berkley, in collaboration with the Massachusetts Institute of Technology. This new generation of computers can learn and improve themselves. Also, the new computers with graphene chips are many times faster and many times lighter than the silicon-based computer we use now. One of their integrated circuits can contain up to 2 million graphene chips.

Since the new computers with graphene chips can learn, they will be the basis of the future artificial intelligence.

Also, graphene-based solar panels were found to have the highest efficiency of transforming solar energy into electrical for the lowest price.

The first digital camera with graphene chips was created in Spain.

And this is just the beginning. There will be many new technologies based on graphene.
