What do you think about our new web site?

Love it, indeed
Really good solution
Same as old one
The old one was better
This is a new option

Quote of the day

People say we're running out of energy. That's only true if we stick with these old 19th century technologies. We are awash in energy from sunlight.

An environmentally friendly, energy-dense sugar battery

RATE THIS! +39

A Virginia Tech research team has developed a battery that runs on sugar and has an unmatched energy density, a development that could replace conventional batteries with ones that are cheaper, refillable, and biodegradable.

 
The findings from Y.H. Percival Zhang, an associate professor of  biological systems engineering in the College of Agriculture and Life Sciences and the College of Engineering, were published in the journal Nature Communications.
 
While other sugar batteries have been developed, Zhang said his has an energy density ten times higher than others, allowing it to run longer before needing to be refueled.
 
In as soon as three years, Zhang’s new battery could be running some of the cell phones, tablets, video games, and the myriad other electronic gadgets that require power in our energy-hungry world, Zhang said.
 
“Sugar is a perfect energy storage compound in nature,” Zhang said. “So it’s only logical that we try to harness this natural power in an environmentally friendly way to produce a battery.”
 
In America alone, billions of toxic batteries are thrown away every year, posing a threat to both the environment and human health, according to the Environmental Protection Agency. Zhang’s development could help keep hundreds of thousands of tons of batteries from ending up in landfills.
 
This is one of Zhang’s many successes in the last year that utilize a series of enzymes mixed together in combinations not found in nature. He has published articles on creating edible starch from non-food plants and developed a new way to extract hydrogen in an economical and environmentally friendly way that can be used to power vehicles.

Energy demands are getting bigger all the time and we could running out of resources - this battery could be a good solution at least for some devices - promising Reply

Great use of enzymes and application of a biochemical, catalyzed reaction to get energy. They constructed a non-natural synthetic enzymatic pathway that strips all charge potentials from the sugar to generate electricity in an enzymatic fuel cell. And the main byproduct is just water

Another good think is that the fuel sugar solution is neither explosive nor flammable and has a high energy storage density. Reply

This is exactly what rapidly growing, portable electronics need: high-energy-density, green, safe batteries. Highly desirable! Reply

Recently there was a serious attempt to reintroduce nuclear energy at a large scale. This is a proposition that urges a crucial discussion on the role of nuclear power in fighting climate change.

I think that this is not the case. Solar and wind have scaled up enough already to make nuclear lose in the market place. Reply

The "nuclear" vs "renewable debate is open and different countries are adopting different policies. I believe we need both Reply
