DailyDirt: Cool Graphene Tricks

Carbon is an incredible element. It comes in the form of diamond, but it also forms other allotropes such as nanofoam, carbyne chains, buckyballs and chaoite. Carbon also make graphene, and that's a material that could have a lot of potential, if we can figure out how to make large quantities of it economically. Here are just a few properties of graphene.

Graphene is one of the strongest known materials. Its strength doesn't actually scale very well as a bulk material, but on a very small scale, graphene is super strong. [url]
Saltwater flowing over a sheet of graphene can generate electricity. Researchers have only generated very small voltages (eg. 30mV), but if this property can scale, it could create another kind of hydroelectric generator without complex moving parts. [url]
Graphene could be useful in super-capacitors (or ultra-capacitors), as sheets of graphene can be made into flexible, durable and highly conductive electrochemical capacitors. It's just not that easy to manipulate single layers of graphene and create stable devices (yet). [url]

Graphene as Water Filter
You forgot to include one of the most potentially beneficial features of graphene yet if things go to plan. Quick and cheap water desalination.

  Re: Graphene as Water Filter
  Actually, I didn't want to cover that twice: https://www.techdirt.com/articles/20100427/1659259202/dailydirt-separating-salt-seawater.shtml

Fair enough, was on vacation and thought I had gone back to the articles I'd missed that week.
