Combined Energies of Latham, NY,  has announced they will collaborate with DTI to develop the power electronics associated with their new ducted turbine unit.  Their greater than 95% patented conversion efficiency  DC-DC converter topology, is a low cost, high efficiency, passively cooled platform that will significantly improve the economics and performance of the turbine installations.

The first quarter section for the duct has been produced!  Very happy with our partner Empire Fiberglass!

A mock-up/assembly area for the turbine install is complete!

Once the duct fab is finished, installation set-up and fixture location can be completed here before being installed outside at the test sites with the actual blades.

The molds have been pulled and after final finishing they are ready for fab!

The mold being built by Empire Fiberglass for the duct quarter section is complete! Backside with supports is shown below and if you look close you can see the finish surface underneath.  Looks like we may have the first 1/4 section fabbed in a week!

The plug for the duct is finished! Looks terrific.  Next up: Gel coating!

Work is going well on the plug for the duct molds.  Empire Fiberglass Products Inc. is in the final surface finishing stage and the gel coating is almost completed!  Needless to say, we are excited about getting this unit in the air!

We are making progress on the new duct for the 3m rotor thanks to the great efforts of Tom and his team at  Empire Fiberglass Products Inc.! Thanks folks! Looking good!

This is the core plug for the mold. Once the surfaces finished they will then create the mold from which the ducts will be made.

DTI is happy to announce a collaboration with Vistex Composites (http://www.vistexcomposites.com ) out of Schenectady, NY to develop and manufacture a composite rotor blade and hub system for us! Vistex is a manufacturing innovation company that has developed disruptive technology for the manufacture of advanced thermoset and thermoplastic composite products. Their patented Pressure Focusing Layer™ (PFL) process, reduces energy consumption and CapEx/OpEx by at least an order of magnitude.

Thanks to  Empire Fiberglass Products Inc. for bringing up a prototype section of the new duct.  Looking forward to seeing the full size unit and how we integrate it into the turbine itself!
