A Down-To-Earth Wind Turbine
The wind is faster at higher altitudes and wind power is directly proportional to wind velocity cubed. But mounting a turbine up high makes it more expensive to install and maintain, and requires a stronger tower to support such a top-heavy structure. Engineers at SheerWind have a solution: “scoop” the air from up high and bring it down low to drive a ground-level turbine. Oh, and while they’re at it, how about amplifying the wind speed too?
SheerWind coined the term INVELOX - INcreasing the VELOcity of wind - to describe its innovative design. Using a giant omni-directional funnel whose mouths are mounted at the top of a tower, INVELOX brings the wind down to ground level and sends it out through a narrow neck, which increases the wind speed, much like putting your thumb over the end of a garden hose and leaving a tiny opening will increase the water velocity. This makes the turbine smaller, decreasing its cost. And because the turbine is on the ground, routine maintenance doesn’t require climbing a tall tower. Funnel mouths facing all directions eliminates the need for the turbine to rotate towards the wind, resulting in fewer moving parts, less complexity, and increased reliability.
Since traditional turbines have relatively high start-up speeds (8 MPH or 3.6 m/s is typical), they can’t generate electricity at lower speeds. Because the INVELOX design increases the speed of the wind before it reaches the turbine, it allows the system to generate power at wind speeds as low as 2 MPH (0.9 m/s).

Solar Power Windows Fast Approaching Commercial Production
Commercial production of solar windows, using the patented SolarWindow spray-on solar power coating system, may be just around the corner. A recent announcement from US building integrated photovoltaics (BIPV) developer New Energy Technologies Ltd. (which we’ve been following for years) has us feeling that the time may soon come.
As per New Energy Technologies’ recent announcement, the big news is that the fabrication time of the technology has been greatly reduced. The fabrication process, which involves methodically spraying layers of extremely small solar cells onto glass, has been reduced from a couple of days to only a couple of hours. According to the company, the process has been cut to 1/6 of the previous fabrication time.
And perhaps as significantly, New Energy has also reported that it has achieved “a two-fold increase in power conversion efficiency” and improved the transparency in the glass.
