Before clicking on the article, I thought it would be a fruit or vegetable with some electrodes stuck in it.

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)

sucrose can be a great battery.<p>It&#x27;s biodegradable, relatively cheap, dissolves in water (unlike oils) and has a high energy density.<p>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 &quot;doing my research&quot;, whatever)<p>I find a lot of people assuming they are biodegradable, which seems reasonable. But no reports of anybody testing the proposition.<p>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...<p>Does anybody in Hacker News Hivemind know of actual experiments composting nano cellulose?<p>Assumptions or reasoning do not count
