Prototype History

1. PROTOTYPE No. 1 1981 Designed to put in practice Pat: 4,205,943

2. PROTOTYPE No. 2 1984 Designed to study the Augmentor ring effect
3.

4. PROTOTYPE No: 3 (1984-85) Designed & Built Under Contract, NYPA

5. PROTOTYPE No. 4 1987 Designed to study a regular 3 blades new first stage

turbine to replace the Wells turbine of Prototype 2 & 3

6. PROTOTYPE No: 5 (1988-1990) Modified Prototype No.3 with design of No.4

Prototype

7. PROTOTYPE No: 6 (1990-1993) Designed & Built to study proper ratio between

first and second stage turbines

8. PROTOTYPE No: 7 (1995) Designed & Built to study proper ratio between

turbine & Augmentor ring© (Shroud). This system met our goals in output, cost
and design simplicity. Now, the next step was getting the device free of any
support, pylons, barges, bridges or other civil work at a competitive cost.

9. PROTOTYPE No: 8 (2000) Designed & Built to stand free of support,

transportable by highways, simple as possible in "Stand alone" installation and
Utility interconnected with trails at Ontario Power Generation

10. Pre-Commercial 2005 Incorporated design changes from lessons learned from

OPG trial to increase reliability and further reduce costs. Went from 2 generators
to one and adopted the UEK patent pending speed increaser solution. Also
incorporated solid conditioning vanes to replace the tensioning cables.

Chitokoloki design
11. First Commercial Units 2007, two twin turbines for the Chitokoloki Mission in

Zambia Africa
