Cheap Tubes updates us on their graphene paper R&D. They have produced five samples and sent them to an independent laboratory for resistivity measurements. Cheap Tubes reports that they have achieved milliohm resistivity for graphene paper. Cheap Tubes plans to continue their R&D for both resistivity and scalability (on small scale and large scale samples). 

Cheap Tubes recently bought second hand equipment that will be used in their graphene paper R&D. The company bought this used equipment at an auction (it was previously used by now-bankrupt solar panel maker Konarka) and will install it in its new Rockingham, Vermont facility. Cheap Tubes is partnering with American Graphite Technologies, which supplies them with graphite materials. AGT is a publicly traded mineral exploration and technology development company.
