  1. Invisco Tornado gravity rooftop ventilators out perform those from Greenheck, LorenCook, Twin City and PennBarry.
  2. Invisco Tornado hybrid rooftop ventilators offer far better performance than the CSR Edmonds ecoPOWER hybrids.

In 2015 I was selected by CSR Edmonds in Australia to be their US distributor – a huge opportunity. I learned about their Hurricane rooftop ventilator and their ecoPOWER hybrid rooftop and I built a company, EdmondsUSA, to be their distributor. In late 2016 Edmonds canceled my contract. Shortly thereafter  wrote a patent application for the world’s first high performance hybrid rooftop ventilator.

In November 2016 things got even better – IdeaBuyer.com offered to invest $20,000 of their money in my new invention – the first and only residential rooftop mounted whole house fan. Their team of attorneys, designers and sales people are working to file a patent, design packaging and a logo and brand and present my invention to their contacts at 22 retailers with 38,722 stores.
