The suppression of free energy by corporate interests has been made quite famous by the work of Nikola Tesla; and our subsequent continued reliance on fossil fuels and other inadequate sources of energy remains a serious hurdle to overcome.
There are some very promising developments coming out of the various open source DIY groups. These groups are utilizing the vast potential of lower-cost research and networking to provide a multi-faceted approach to innovation that is becoming far more difficult to suppress than the inventions of a single genius such as Tesla.
There has been particular focus upon how to increase battery life, given the ubiquitous nature of our digital gadgets and high-tech infrastructure. A German student, Dennis Siegel, invented a device that builds upon Tesla’s maxim that “throughout space there is energy” by capturing modern-day electromagnetic fields like WIFI and radio waves and converting them to stored energy in batteries. Siegel won a prestigious award when he successfully demonstrated charging one conventional AA battery over the span of a day. Siegel’s full story can be found here.
Now, a new technology based upon the amazing properties of graphene to convert light to electricity is showing signs of surpassing silicon as the most efficient path toward potential free energy. And even if it comes up short of that lofty goal, it still might revolutionize computing and electronics.
A new study from Nature Physics journal states the hard science behind this technology:
As hot electrons in graphene can drive currents, multiple hot-carrier generation makes graphene a promising material for highly efficient broadband extraction of light energy into electronic degrees of freedom, enabling high-efficiency optoelectronic applications.
In layman’s terms: graphene generates multiple electrons from each photon, whereas silicon – the current source of solar cells – can generate only a single electron per photon.
Since graphene can fully convert the energy it receives, nothing is lost in the process, thus providing a huge increase in overall efficiency. Cornell University titled their own review, “Self-Charged Graphene Battery Harvests Electricity from Thermal Energy of the Environment” which encapsulates the magnitude of its potential, as well as hints at the elusive promise of free energy.
The development of improved photovoltaics is exciting enough, as it could drive down the cost of all optical imaging and solar applications, but it is graphene’s potential for revolutionizing computing that could eventually lead to Silicon Valley being supplanted by Graphene Valley.
Enter the “Supercapacitor.”
