Any info on the theoretical capacity of these vs Lithium Ion? I didn't see it in the article. (Obviously it's not a competition, but it'd be nice to have some frame of reference)
The "battery" is actually a capacitor; those tend to have very low energy density compared to batteries, but on the other hand can be charged and discharged very quickly.
It's biodegradable, relatively cheap, dissolves in water (unlike oils) and has a high energy density.
1kg of sucrose has an energy density that is equivalent to 4kW.
A typical daily power consumption of a family home is ~ 11kW
It means that we can power an entire house with ~ 3kg of table sugar.
I have spent five minutes hunting the Interweb for information on the biodegradability of cellulose nano fibres. (I think that is called "doing my research", whatever)
I find a lot of people assuming they are biodegradable, which seems reasonable. But no reports of anybody testing the proposition.
Nanofibres have unique chemical properties and it may turn out that microorganisms cannot process them. I am not a chemist, let alone a bio-chemist...
Does anybody in Hacker News Hivemind know of actual experiments composting nano cellulose?
