The U.S. Department of Energy has said the main thing holding back a major upswing in the installation of renewable energies like wind and solar power is better methods for storing that power when the wind dies, and the sun goes down.
I’ve seen the race to come up with super small and simple properties that can hold a charge on Discovery Channel’s EcoTec series. One researcher was developing batteries from bacteria as thin as a piece of cellophane. It’s not hard to believe that in the near future we will have super small batteries that hold a mega charge that is if we allow progress to happen and quit running back to a source that will eventually run out like oil.
The latest in new energy storage comes from the University of Texas at Austin. They’ve come up with a carbon structure that is only one atom thick called graphene. Graphene, “could eventually double the capacity of existing ultracapacitors, which now are manufactured using an entirely different form of carbon.” Ultracapacitors are the other means of electrical storage besides batteries. This technology “could greatly improve the efficiency and performance of electric and hybrid cars, buses, trains and trams, even office copiers and cell phones.”
And think of the storage capacity for wind and solar. In 2007, “U.S. wind power installation grew 45 percent.” Rod Ruoff, a mechanical engineering professor that is working on the graphene project said that if installation grew that much every year for the next 20 years, “total energy production from wind alone would almost equal the entire energy production of the world from all sources in 2007.”
That’s impressive. We keep hearing that many of the green energy propositions are impossible but with ever evolving methods, materials, and discoveries happening every day who is to say what is possible? We need to unleash and nurture this ingenuity and quit hindering progress. I’m tired of fueling cars at the pump, and plugging in cell phones constantly to recharge them, basically because I forget to do that until I’m in a hurry. There’s got to be a better way.
