Our Products

Alternative Sustainability in New York, NY is the first and only company in the nation to develop a way to capture the  current energy in every building in this country and use it to produce meaningful, clean power.

Our Patent Pending devices use a one of a kind, patented turbine, described as the first new generator in 100 years.  They can be installed in or on any type of building, large or small, and produce clean power, thus reducing your dependence on electric company grid power.

Turbine Slide Frame

Today, buildings spend tens of thousands of dollars bringing air into buildings and exhausting air out of them. 

Now you can capture all this air power to create as much energy as you want.

  • Create large amounts of power using existing building mechanical systems.
  • Will operate inside of any HVAC unit or ductwork.
