Sugar batteries could be greener, cheaper and store more energy than lithium-ions

Sugar batteries could be greener, cheaper and store more energy than lithium-ions | Tools & Other | Scoop.it

Even today's best rechargeable lithium batteries do lose their ability to hold a charge after a while, and are considered toxic waste once discarded. In just a few years, however, they may be replaced by batteries that are refillable and biodegradable, and that will also have a higher energy density yet a lower price ... and they'll run on sugar.

"Sugar is a perfect energy storage compound in nature," says Virginia Tech's Prof. Y.H. Percival Zhang, who is leading the research. "So it's only logical that we try to harness this natural power in an environmentally friendly way to produce a battery."

Zhang's isn't the first experimental sugar battery, although he claims that its energy density is "an order of magnitude higher than others."

It's actually a type of enzymatic fuel cell. For fuel, it utilizes maltodextrin, which is a polysaccharide made from the hydrolysis of starch (polysaccharides are chains of sugars). The catalyst in its anode is made from inexpensive enzymes, as opposed to the costly platinum that's used in regular batteries.

When the maltodextrin is combined with air, water and electricity are produced. Unlike the case with a hydrogen fuel cell, however, the sugar battery is non-explosive and non-flammable.

Zhang envisions users refilling the batteries with sugar when they need refueling, "much like filling a printer cartridge with ink." He hopes that they may be powering electronic devices in as little as three years.

Can we build an artificial superintelligence that won't kill us? | Tools & Other | Scoop.it

At some point in our future, an artificial intelligence will emerge that's smarter, faster, and vastly more powerful than us. Once this happens, we'll no longer be in charge. But what will happen to humanity? And how can we prepare for this transition?

Sugarbox is a free web app which allows you to share any web app you are working on with anyone you wish to collaborate with.


To use it, you simply go to the web app, open it and then click on the Sugarbox bookmarklet, and you are ready to invite anyone to co-work with you, in real-time, on that app.


Once you are collaborating with someone you can see their cursor and their name in real time. You can text chat and annotate the screen.


A unique feature also allows you to easily record what's being shown on the screen, including your cursor movements, and can be easily shared with anyone. 


My comment: Excellent resource if you want to collaborate in real-time with someone else on the same app. 


Free to use.


Try it out now: http://www.sugarbox.io/
