NASA, the military, aviation, and many other industries use Technology Readiness Levels (TRL) to plan a path to full commercialization of their products. TRL consists of nine rigorous stages, each with its own parameters, that a technology must pass before becoming fully certified. Wind turbine development also needs to go through these different levels.
Wind Harvesters and their earlier prototypes have completed the first six levels. In February 2022 Model 3.1 entered TRL 7 (full-scale prototype in industry-turbulent wind conditions). In 2025 the Wind Harvester 4.0 is expected to begin TRL 8, third-party certification. In 2026, we expect to sell 50+ turbines in order to complete TRL 9 (bank financing of customer loans). This final step should be completed in early 2027, opening the company up to a significantly higher valuation.
