New Patent Purposes Filed for Distinctive Wind Turbine
Davis, California: On April 3, 2023, Briggs IP filed 4 patent functions for improvements on Wind Harvest’s design of its Wind Harvester 4.0 generators. Their prior artwork search discovered that none of those concepts had ever been used earlier than for wind generators.
Being first-to-market within the mid-level wind market with a utility-scale vertical axis wind turbine gave Wind Harvest the chance to interrupt new floor in VAWT design. For instance, a polygonal mast that makes use of nutbars inside on its flat sides has by no means been utilized in a VAWT earlier than and has many benefits over conventional pipe masts.
“It is going to be tough for future rivals to construct a rugged, environment friendly, easy turbine with out licensing the Firm’s pending patents,” stated Kevin Wolf, CEO and co-founder. “There are solely so some ways to place collectively a metal and aluminum turbine and our engineering crew discovered distinctive, price efficient options for probably the most problematic components of VAWT design.”
The Firm launched one of many 4 patents for public viewing. Previous to the “Vertical Axis Wind Turbine with Polygonal Mast” innovation, Wind Harvest and different VAWT prototypes have largely used metal pipe for his or her masts.The pipe and flanges and welding the sections of the pipe to flanges, bolting the flanges collectively and connecting that three piece mast to the drive shaft are costly. The Wind Harvester Mannequin 3.1 mast price greater than $30,000 for a single turbine. The Mannequin 4.0 mast prices lower than $8000 which embody charges licensing the nutbar patent for this distinctive software.
“We’re happy that our nutbar fastener packs (U.S. patent 8,713,896 B2) enable Wind Harvesters to utilize a polygonal mast and drive shaft heads,” stated Jeff Willis, CEO of Northstar Wind Inc. and inventor of the distinctive nutbar. “Six flat sides on the mast make it simple and cheap for plates and flat bent items of steel to be bolted along with nutbars deep contained in the hole mast. That’s the breakthrough that nobody has ever accomplished earlier than.”
Wind Harvest’s Mannequin 3.1 used three items of pipe with 5 cast flanges horizontally hooked up to their ends with costly “full penetration” welds. In distinction, the 4.0’s polygonal mast makes use of two sheets of steel the place all of the holes are made whereas flat. These two items are then bent with a lot less complicated vertical welds bringing them collectively. The one polygonal mast is way simpler to put in as effectively..
“All the new patents we not too long ago filed are much like this in that they make our Wind Harvesters simpler to make, assemble and set up,” acknowledged Dr. Ola Ojala, Wind Harvest’s Principal Engineer. “Two of the patents additionally make the turbine extra environment friendly by decreasing the drag it experiences because it rotates again into the wind.”
