Seems very promising.
*If it works*, this could be a truly disruptive technological breakthrough that has the potential to change the economics of our entire energy distribution system.
Energy distribution costs are a function of providing energy to meet peak demand.
With this type of technology, peak demand can be managed by storing energy at distributed sites during off-peak hours. Implementation could be driven by reduction in energy costs for consumers that "bank" off-peak energy to meet peak demand needs.
