Sheerwind-Invelox, a ducted-turbine fiasco, officially went bust in early 2018. Incredibly, there are a number of promotional videos still on line at youtube.com and on vimeo. The latter is even more surprising since it’s a pay to use platform. Sheerwind-Invelox’s subscription must still be in force. That won’t last forever.
Daryoush Allaei extolling the wonders of his device in his native land. Note the location of the device–down below the ridge on which they are standing. Also notice that there are some real wind turbines in the background.
The Nature Conservancy (TNC), one of the nation’s premier land preservation trusts, isn’t talking about its failed investment in a ducted wind turbine debacle 1,000 miles from Hawaii.
The following are comments to Another Ducted Device Dead: SheerWind-Invelox Bankrupt. They were so insightful I decided to repost them here where they are more easily archived.
Is the end near for SheerWind’s Invelox ducted wind turbine? The problems with SheerWind’s design are coming to a head as its signature clients lose faith.
Sheerwind makes radically inappropriate comparisons between their long-disproven approach to wind generation and actually useful wind generation. The numbers show that they are likely about eighteen times worse at generating electricity from moving air than a truly equivalent wind turbine would be, and will require an order of magnitude more material to achieve that.
