synthetic enzymatic pathway Nature Communications 5, Article number: 3026 doi:10.1038/ncomms4026 Received 09 July 2013 Accepted 26 November 2013 Published 21 January 2014
Abstract

High-energy-density, green, safe batteries are highly desirable for meeting the rapidly growing needs of portable electronics. The incomplete oxidation of sugars mediated by one or a few enzymes in enzymatic fuel cells suffers from low energy densities and slow reaction rates. Here we show that nearly 24 electrons per glucose unit of maltodextrin can be produced through a synthetic catabolic pathway that comprises 13 enzymes in an air-breathing enzymatic fuel cell. This enzymatic fuel cell is based on non-immobilized enzymes that exhibit a maximum power output of 0.8 mW cm−2and a maximum current density of 6 mA cm−2, which are far higher than the values for systems based on immobilized enzymes. Enzymatic fuel cells containing a 15% (wt/v) maltodextrin solution have an energy-storage density of 596 Ah kg−1, which is one order of magnitude higher than that of lithium-ion batteries. Sugar-powered biobatteries could serve as next-generation green power sources, particularly for portable electronics.

According to the developers this batter could possibly outdo a lithium battery. There is no end to cleverness.

Which is why I am semi optimistic about the future.

I'm optimistic about the future too, but not because these good folk think they've solved electricity storage from solar and wind sources. What is really being said is that current capital expenditures on these "renewables" have not yet been justified. Frankly, for other reasons they never will be. For instance, there is no way to increase the amount of sunlight that hits any square meter of ground. That's it! (And don't forget the degrading variables.)

The sugar batteries were intended to run you cellphone and computer.

Just read it. Good news. A decent battery with large energy capacity per unit mass that is cheap to manufacture is what it will take to make so-called renewable energy sources practical. That would be solar (mostly p.v.) and wind. The only way to tame intermittent energy sources is to store their output so that the energy can be brought in on demand.

The amount of energy from the Sun that hits the ground in one day could keep the U.S. running for something like two years.

We only need to harvest a very small part of this energy.

That's what we do--already.

"a very small part"

how many more small parts do we need to equal your small part?
