That sounds achievable. I'd inline the relay and several charged tubes in a lightning arrestor and check them when the weather clears.
As a concrete amendment, 6 grams would reinforce 6kg of concrete. Combine that with basalt geomesh reinforcing and
Roman Pozzolanic cement and you'd have something

The pozzolanic reaction is the chemical reaction that occurs in portland cement containing pozzolans.It is the main reaction involved in the Roman concrete invented in Ancient Rome.At the basis of the pozzolanic reaction stands a simple acid-base reaction between calcium hydroxide (as Portlandite*) and silicic acid.

Reduce this to a DIY procedure, and the mass of concrete structures would be reduced by the amendment, the mixture and the lack of need to protect the reinforcement from spalling.
The OP story about power might need a suitable environment. I propose the thermocline just outside the mouth of the Strait of Gibraltar.**

Turbulent Dissipation in the Strait of Gibraltar and ...

The Strait of Gibraltar is a channel with a permanent two-layer flow strongly modulated by energetic tidal currents. Compared with the open ocean thermocline, turbulent dissipation rates, ε, are high throughout the strait. Two flow regimes, however, have particularly intense dissipation: the lee west of Camarinal Sill during strong outflow of ...

The Strait of Gibraltar is located between the southern coast of Spain and the northern coast of Morocco ... several-hour depression of the thermocline with an amplitude of approximately one-half that of the lead soliton exists to the rear of the packet. Over the remainder of the tidal period, the
