Intelligent Revolution

EXRO Technologies Inc. is a clean energy company that has invented, designed, and prototyped the world's first Variable Input Electric Generator (VIEG, pronounced veej). VIEG re-defines the economics of renewable energy generation (big and small wind, run-of-river, tidal). It represents the first truly innovative electrical generator to be introduced in 175 years, representing a critical part of the solution the world is seeking to economically reduce green house gas emissions. EXRO is seeking funds to commercialize this technology.

Unlike traditional generators, which were designed to convert stable energy sources (coal/hydro/nuclear) into electricity, the VIEG has been designed from the ground up to more efficiently convert variable energy sources into electricity. In today's carbon constrained world, the benefit is material, because traditional generators cannot self-adjust to the input swings inherent in renewable power sources. The root of the problem is that traditional generators rely on mechanical systems (gearbox, “pitch & yaw”, linking multiple generators) that artificially adjust shaft speed to match the operating band of the generator. These mechanical adjustments make it possible to use a traditional generator in a variable application, but they also reduce the overall economic output of the machine.
