Ethanol
Could somebody please extent the list with ethanol?

I don't know how to do it technically (how to expand a list in Wikipedia).

26.8 MJ/kg, 21.2 MJ/L

Thank you. — Preceding unsigned comment added by 94.114.202.121 (talk) 09:21, 23 May 2018 (UTC)

Elastic Energy
I'd be really interested to see [Elastic_energy] added to the list. What is the energy density of a metal spring? Of an rubber band? Compressed air? They're all are used to store energy, but how good are they?

Wired had an article recently about rubber bands. — Preceding unsigned comment added by 2001:8003:2FEA:AE00:34BD:5B2D:DEED:A92C (talk) 02:07, 25 March 2018 (UTC)

I'm pretty sure I found a table somewhere on a Wikipedia page about strength or stiffness or something which contained this information for many types of materials. I always have a hard time finding it though. I agree that adding [Elastic_energy] for a variety of materials would be very useful. Anomalistic (talk) 14:43, 24 October 2019 (UTC)
