Validate all parameters with calculations and modelling, including electric and magnetic fields, compliance with safe field levels outside the enclosure, mechanical design, acceptable beam vibration and beam displacement, and tolerance to earthquakes. 

In flood plains, the enclosure will be elevated, like railroad tracks on a gravel berm. 

Complete initial testing at high voltage with Van de Graff generators by March, 2025. 

Hire EPRI or a utility to test a 10-foot, 230 kV line at AC operating and surge voltages. 

Test thermal expansion joints at 3000 amps for 15,000 full cycles (40 years equivalent).

Build a ¼ mile line, fully enclosed, and connect it to a 230 kV sub-station.

Run 100 MW of power from the sub-station into the line, and then back to the sub-station.

Install breakers to protect the sub-station, and a re-connect switch to by-pass the test line.

Install fiber optic cameras to monitor line performance.

Build a 50 – 100 mile commercial line with our utility and/or developer partner.

This will be the first of many commercial Ultra-Compact, High-Capacity, and Low-Cost AC Transmission Lines for Regional and National Electricity Grids.

Once the risk is low, Ultra-Compact lines will become the cornerstone of electricity grid, and enable the U.S. to increase grid capacity fast enough to support renewable energy, pumped-hydro, electric cars and heat pumps.
