COMMERCIALIZATION
- Company sales as a result of
SBIR were $200K and growing
- ITFT increased from a few employees
to 12 full time and 8 part-time employees
- Phase III monies totaled $4.7M
from several government and private sources. The DOE National
Renewable Energy Labs (NREL) is the largest government contract
- Private investment provided
the financing of a just completed production facility
