Is This Rooftop Turbine the Future of Energy… or an Old Idea?
TLDRThe video discusses the VX175, a shrouded rooftop wind turbine developed by Norwegian company Ventum Dynamics. Unlike traditional wind turbines, the VX175 features a shroud that accelerates wind, allowing more air to pass through and potentially increasing power output. The design has been misunderstood as being inspired by an 18th-century invention by Erasmus Darwin, but the VX175 is actually a modern take on the IMPLUX turbine, invented by engineer Varan Sureshan. The turbine is designed for urban environments, where it can harness energy from turbulent airflows common in cities. The VX175 is stationary except for the rotor, which reduces maintenance costs and noise. While there's no public performance data yet, the turbine shows promise for decentralized power supply in commercial and residential areas, particularly for apartment buildings and industrial zones.

Q & A
What is unique about the Aeromine rooftop wind turbine?
-The Aeromine rooftop wind turbine is unique due to its 'motionless' design, which differentiates it from traditional wind turbines.
What is the name of the new rooftop turbine released by the Norwegian company Ventum Dynamics?
-The new rooftop turbine released by Ventum Dynamics is called the VX175.
How does the VX175 shrouded wind turbine differ from traditional wind turbines?
-The VX175 features a lantern-like shroud wrapped around the body, which accelerates the wind and allows a greater volume of air to pass through the turbine, enhancing its power output.
Who is Erasmus Darwin and what is his connection to the concept of shrouded wind turbines?
-Erasmus Darwin was an English physician and the grandfather of Charles Darwin. He developed a shrouded windmill, which is an early concept that has similarities to modern shrouded turbines like the VX175, although the modern design is not directly based on his work.
What is the IMPLUX turbine and how is it related to the VX175?
-The IMPLUX turbine was invented by engineer Varan Sureshan and represents a 'static turbine' and 'dynamic turbine' combination for higher power extraction. The VX175 incorporates features from the IMPLUX, and Ventum acquired the patent for it, making the two turbines essentially the same machine with the VX175 optimized for manufacturing.
What are the advantages of using a shroud in a wind turbine?
-Shrouds in wind turbines offer several advantages, including the concentration of wind energy, low exit pressure leading to increased airflow and faster wind speeds, avoidance of tip losses, and overall increased efficiency and power output.
Why might shrouded turbines like the VX175 not be economically practical for traditional wind turbine applications?
-Attaching a heavy shroud to an already massive traditional turbine tower could threaten structural integrity, and the cost of such components has historically been a consistent drawback, making them less economically practical for traditional applications.
What is a DAWT and how does it differ from a traditional wind turbine?
-A DAWT, or diffuser-augmented wind turbine, is a type of turbine that uses a shroud, duct, or diffuser to increase speed and power output. Unlike traditional wind turbines, DAWTs are designed to be more efficient in areas with lower wind speeds, such as urban and residential areas.
What are the potential benefits of using the VX175 turbine in urban environments?
-The VX175 turbine can be mounted on the tops of buildings and is designed to capture energy from turbulent airflow common in cities. It can harness the 'edge effect' where wind is redirected upwards and accelerated by buildings, potentially leading to higher efficiencies and power output in such environments.
How does the noise level of the VX175 turbine compare to general environmental noise standards?
-The VX175 produces noise at about 40 decibels in 6 m/s (13.4 mph) winds, which is quieter than the 55 dB considered acceptable for human health by the U.S. Environmental Protection Agency.
What are the potential applications and target markets for the VX175 turbine?
-The VX175 is suitable for commercial buildings, offices, and apartments. Ventum Dynamics is also releasing the VX300, a larger version for industrial areas like warehouses and storage facilities. These turbines aim to bring wind power to more populated areas where traditional wind turbines may not be feasible.
