Thanks for everyone’s comments, relevant or not. Concluded that 200’ in this situation isn’t viable. Didn’t find any pumped hydro under ~280’. Could increase flow to account for lower head but that requires more turbines/pumps – so greater capital equipment and operating costs. As pumped volume...
There is a huge need for hydrogen in the Midwest for the production of anhydrous ammonia for use as a plant fertilizer AND potentially as a direct fuel. Yes, a fuel - http://www.energy.iastate.edu/Renewable/ammonia/index.htm . The UP has a locomotive running on anhydrous ammonia and the ag...

Don't know enough to factor efficiencies into theoretical calculations so extrapolated from the Salilna Pumped Storage Project in Oklahoma. 100...
Yes, lots of unknowns but one must start somewhere - land availability, soil permeability, electricity cost for pumping, water availability, etc. Would 12,000 acre feet at 200’ of head make pursuit worthwhile? Can find nothing similar in the Midwest. The closest in concept is a proposed...
A large wind farm is going in ~1 mile from an incised river valley with 180 to 200 feet of fall from the surrounding land to the riverbed. Does this represent a viable pumped energy system?
Jbartos,
1. Please reread origninal post. 1,400 fixtures/bulbs per acre, each at 1150 watts which is why I'm interested in power distribution.
2. Not in the formations we are looking at, even after rare earthquake events (Mew Madrid fault).
3. Yes.
4. Not enough light, the seedlings die. No CO2...
Ares - Lots of problems, all of which can be solved. We're not at the point where there is concurrence that this ia d viable project. We've dealty with heat, ventiallation, worker safety, water control, biocontainment, equipment, etc. I am just trying to get a handle on the power distribution...
Started there. From their perspective, these are abandoned mines and they have no authority. Found the same respones at the state level in 4 states we have looked at. In some locations where the mine is under a town/city, an abandoned mine being repurposed will be considered a building and hence...
Am working on the design of an underground farming operation for the production of transgenic agricultural crops that have been genetically engineered to produce pharmaceuticals. Think of this facility as a totally contained very large growth chamber (or greenhouse). Facility will be built in a...
