Some day specific materials we find in plants and animals will be able to be grown artificially, making then even more sustainable since the time and resources that go into raising, culling and processing livestock for harvesting won't be part of the process

And moreover, when we are at that point, we will be able to develop improvements on those materials and tailor suit them to various industrial applications

Made from chitin. How boring. Call me when the figure out how to turn baby seals into jet fuel. Then we'll be on the right track.

Q. What's the fastest way to eliminate crustaceans from planet Earth?

So the prophesized war with the crab people is indeed coming?

FTA: This design means that two-thirds of the battery is biodegradable; the researchers found that the electrolyte broke down completely within around five months. Compared to conventional electrolytes and their thousand-year lifespans in the landfill, Hu says, these have little downside.

Um, I would say having to replace a battery every 5 months would be a downside?  Maybe I'm missing the point (it's happened once before, and will happen again)

But that's a pretty interesting concept if it can scale.  Genetically breed the crabs/similar organisms to grow the needed components, harvest and use.

im fairly certain they mean that after the usable life of the battery is over and it is put into a landfill it breaks down in 5 months. not that the entire lifespan is 5 months

Breed more Marylanders?  We've spread the gospel of Old Bay across the country (to the annoyance of fark), perhaps we can do the same with crabs and other shellfish.  Convince the rest of the country that your trash food (lobster) is a great delicacy?  Note that researchers are located in the University of Maryland (land of crab eating, even if all the crabs are gone) and the University of Houston (where they come from now).

I'm getting a little impatient for one of these "revolutionary" new battery types to finally hit the market. As someone who recently discovered the battery in their old laptop has started to swell, I've become somewhat fed up lately with the inherent downsides of lithium ion battery tech.

There are few things more broadly and deeply studied than battery technologies. There will be a million of these stories for every one that makes it into broad commercial usage.

Not saying you're wrong... but that's a whole bunch of science I don't understand.  How would the battery know to not break down when it's charged?

How long would the battery last if it had a charge in it before breaking down?

My head hurts.  :)

So a battery is based on a chemical reaction. That reaction is outside and independent of the overall decomposition of the object itself. Kind of like if you have a chair and it breaks, its still pieces of a chair that arent gonna just stop existing because they no longer function as a chair. in this case, after the chemical reaction thaty give the battery power has been exhausted, the chemical remnants of those reactions will take 5 months to break down as opposed to the loooong time things like lithium ion and lead/acid components of regular batteries take

But presumably they don't know they've been discarded. I guess it's more like "leave this battery open in the sun and it will disappear in a few months without damaging the atmosphere"

The bit in TFA about the danger of potassium hydroxide is BS. Yeah you don't want it on your skin, but it's not toxic at lower concentrations. And if you dumped it into the ocean it would actually help the planet, reducing acidity and helping to draw CO2 out of the atmosphere.

in use theyre not exposed to the same level of elements as in a landfill. a piece of iron doesnt know when its in a scrapyard per se because its not sentient but it does react differently between a controlled temp/huidity environment where it doesnt touch much besides some plastic directly and an environment where its covered by organic matter and bacteria and going thru wet/dry cycles

It'll take years to develop this tech

if they're interested, they can send me the fresh crabs, and I'll be more than happy to return the shells they'll need for their research

/I'll even pay shipping
//both ways

Lots.  They actually catch them, drain some blood and release them.  Doesn't wipe out the stock.

Really, the biggest danger to a species is being an ingredient in traditional medicine boner pills.

Their Delaware Bay population -- the largest in the country -- had plunged from around a 1.24 million to ~a third of that. It has rebounded a bit.
