In order to build scale for renewables we need renewables to be commodifiable. To do the storage and shipment thing we need for these renewables to be pipe ready. Compressed air and hydrogen and oxygen rich compressed air can be the answer. My design for this would be multi utility pipes (water systems galore, natural gas, oil, sewage, broadband conduits, other cash flows) that also do double duty as rail and monorail transit system backbones. The Tripe System, 11 pages illustrated, is a mega-system design that meet all the parameters but one: It is not designed to be an electric grid centric system. It can get us off of fossil fuels people. Hello. We are still trying to fit everything under the sun onto these electric grids, and it's a waste of time. Renewables MUST be configured for storage and shipment of energy, or they can't be scaled. My wind and wave hybrid systems (Georges Bank Mega-Mills) CAN'T ship electricity functionally with any practicality from Georges Banks to Boston or New York. It can't be done. Furthermore most RE sites are remote, geothermal, wind, wave, tidal, solar, and this is a fact we need to zone in on, and dominate. Let's get on with crunching some basic numbers for the Tripe (track+pipe) System: How much horsepower is contained in a three track line one mile long? Solving this thing will be about conversions, and uses (CAES air conditioning and refrigeration, autos, washing machines, etc) and reconversions. This work needs some credibility, because the smart grid is so undeserving of it. I think scaled CAES and hydrogen as a backbone is far more credible than praying to the gods of the smart grid for help. The smart grid is aparently a slow learner. I'm a fisherman, and could use some help with the analysis, that is help, not shoot from the hip... "Pipes can't work!". Pipe can ship horsepower, store horsepower, and can be scaled with no problem. 8,000 psi, thirty or thirty six in diameter pipe, times six, what's that for horsepower, for one mile? That doesn't take a subsidy, just work, and some curiosity, and some interest and intellect.
