Question 1 of 13

What is proven today, and what is still to come?

Vega proved the core technology, and Pulsar has run 100 fault-free cycles at low speed. High-speed testing comes next.

The full answer

Vega, the first prototype, proved the rotor design, bearings, vacuum and controls. Pulsar, the full-size prototype, is assembled and has completed 100 fault-free charge and discharge cycles at low speed on a steel setup rotor.

Still to come are the carbon-fiber rotor, high-speed testing in the test cell and measured round-trip efficiency. After that, beta units go to a utility pilot with independent data.
