Why Coconuts Could Be the Hydrogen Storage Material of the Future (technologyreview.com)

This is hilarious! They're already using coconuts in ITER (the fusion reactor) http://hplusmagazine.com/2009/10/27/coconut-futures-and-ther... It seems coconuts are the hi-tech fruit of the future!


If we use the term drupe, it sounds slightly less crazy. Drupe enabled reactors seems like a phrase I could get behind. Fruity Reactors, or the Coconut Reactors do not inspire confidence. Though a bag of fruity reactors does sound tasty.


Sounds very exciting. MetalHydrides have been a "promising" material for hydrogen storage for decades now but haven't really proven to be a practical material. This entirely new direction of research is very promising.

From the original paper on arxiv ( http://arxiv.org/pdf/1409.7219v1.pdf ), sounds like that desorption (release) of hydrogen gas from the material requires extreme low pressures to be created. I'd be curious to learn the energy equation there... that is, how much energy needed to be consumed to recover the gaseous hydrogen back from the material (say, as percentage of energy stored in H2).


whenever i read about great new carbonized material and it great absorption/porousness and multiple cycles mechanical resistance the first question comes - have they tried it for batteries as current carbon electrode's limited ability to absorb lithium is among the main factors limiting the batteries capacities (and lifespan)


We can use sparrows to import them from the tropics


I'm sure that we've got other means of transporting coconut that are less seasonally dependent.


African or European?
