"Here we concentrated on the new principal of the waving potential and how to scale it up," says Guo. "Next we are making efforts to amplify the power density." To this end the team have already demonstrated the potential to scale up the electricity induced through connections in series and in parallel. The high-quality graphene required to observe a response also poses challenges for future work.

To start, the stuff is made with the AA-8000 aluminum alloy. This alloy became the required standard for aluminum wiring to resolve the problems of the poor quality aluminum wiring used prior to 1972 (AA-1350 aluminum). Adding the copper cladding allowed the wire to be connected to devices that did not have to be rated for “aluminum.” In fact, brand new, 2014, receptacles that are Tamper Resistant, come rated for both copper and copper-clad wires. This is a testament to the fact that receptacle manufacturers do not see a problem with copper-clad wiring.

 “CCCA is raising the alarm again and cautioning by citing real-life failures with copper clad aluminum (CCA) communication cables offered by low cost, online suppliers,” comments Frank Peri, CCCA executive director. “These suppliers promote and advertise CMR or CMP cables that bear counterfeit certification marks or have no listing or verification marks from independent third-party testing laboratories. Using the lure of low price, some online suppliers can entice customers unaware of the true nature and quality of their cables. ”

An energy recovery ventilator (ERV) is a type of heating, ventilation, and air conditioning (HVAC) equipment that uses the energy associated with the thermally conditioned air being exhausted from a building to precondition the incoming air.  ERVs, which offer many advantages for both improved indoor air quality (IAQ) and reduced energy consumption, are one of the fastest-growing segments of improved IAQ management in buildings.
