Title: Graphene membrane harvest hydrogen from the air
Post by: Nink on December 02, 2014, 11:57:51 AM
Scientist are working on a membrane to harvest hydrogen.  I think we need more information anyone have a copy of the actual peer reviewed article and what is the energy cost of harvesting hydrogen. http://rt.com/news/209555-graphene-hydrogen-discovery-fuel/

One can catalyze hydrogen rather inexpensively by producing Graphene in a cheap LighScribe DVD drive, cutting strips, soaking strips in distilled water with nickel plates for the purpose of electroplating the Graphene with nickel ions.  Then one can produce hydrogen quite inexpensively.....

Compare the output from a 1.5v AAA battery as shown, to the high voltage setups of the past.

Nice find @techstuf I wonder how long the 1.5v battery lasts and how many moles of hydrogen per joule is created.

The fact that it produces hydrogen bubbles visually at that voltage is significant.  Also, check out what they're doing with 'Hemp Bast'....
