Ping.
That’s all well and good but how much damage will be done to them by cleats; and are they as easy to repair/replace as sod?
Grid - Gridiron
Same thing, right?
This has the sound of a business plan that only makes sense from the standpoint of a state-run neo-fascist economy fed by endless amounts of cheap labor. Like China. Otherwise, giant batteries make no more sense than giant capacitors or giant windmills.
This is interesting. It would be fun to amortize to 20 year total cost of ownership of a coal burning plant, a nuclear plant and a wind farm with these batteries. Let’s also factor in reliability and cost of power produced.
I suspect the wind farm (or solar farm) will still lose.
There is a large wind farm on I-65 north of Indianapolis. Usually when we drive through virtually all the blades are turning. We were driving down from Chicago on the 1st of January on a particularly windy day and maybe one in ten was operating. I assumed they had batteries to store the excess power until I saw that.
It never dawned on me that batteries may be prohibitively expensive. Too bad they can’t sell excess power like Washington state does to California.
I knew a storage facility in the 1970 call Crater Lake. Excess power was used to put water up to a mountain lake, then when needed though Hyrdo generators. Don't know how efficient that was. But how efficient would lake storage be in comparison to batteries? And how long would the storage last in comparison?
These are the engineering questions needed lest we have another Solyndra.
Primary Supply: 138 kV / 187 A / 59-60.5 Hz
DC link Voltage / Current: 3440-5200 V / 12000 A
Total AC Power: 46 MVA
Let see pro football stadiums are used 16 weekends (plus a few playoff cames). For the other 330 days a year should we flood them and turn them into giant batteries. Great idea....
Is the author taking about a kick-ball field size battery?
Liquid Thorium reactors..... We need them.

So wind power is even more expensive?
The whole idea is DOA. Battery economics will never be able to overcome the drawbacks of battery physics. That is to say, the energy produced by ‘renewable’ resources will NEVER be able to overcome the cost of building, maintaining, and eventually disposing of and replacing the battery. ALL batteries are consumable, and you have to factor that cost into the entire picture.
Batteries do wind up failing over time. Internal resistance builds up due to heat. They don’t last forever.
Great!
A giant football pitch sized battery that can go into a violent discharge state.
Wonder what that looks like?
Pumped Hydro storage is the most efficient and economic energy storage system over a long period of time with daily cycles. The efficiency of this system is typically between 70% and 85%.

Obama Energy Department Is Going Back and Changing Solar Energy Loan Press Releases
The Obama Administration spent nearly half of the $38.6 billion ($17.2 billion) set aside for his green energy programs and was only able to create 3,545 permanent green jobs. This comes out to a staggering $4,853,000 per job.
a battery will retail for $1000 a piece with a $995 tax credit available from Uncle Sugar.
