Propellerless Turbines: Promising Innovation in Renewable Energy
Wind energy is always related to large turbines with propellers that rotate depending on the strength of the wind. However, have you ever thought if there was one where these big shovels were no longer necessary?
“Unlike conventional turbines that resemble gigantic white fans, the vortex has a cylindrical design and no propellers. This innovative design allows the device to vibrate with the wind, a movement that generates energy efficiently,” says Professor Fernando de Lima Caneppele from the Faculty of Animal Science and Food Engineering (FZEA) at USP.
Differences
In addition to not having propellers, this new technology aims to innovate in the field of wind energy generation.
“The structure is designed to sway with the wind, a process known as vortex-induced vibration. This oscillation is then converted into electrical energy, a process that quickly adapts to sudden changes in wind, making it ideal for urban environments.”
But not everything is perfect. Because this technology is recent, it is still necessary to identify its challenges and limitations. “As with any innovation, it is essential to also address the long-term viability and integration of these turbines in different environments. Furthermore, market acceptance and adaptability of existing infrastructures are crucial factors for the success of these technologies.”
Benefits
The professor emphasizes that this technology is capable of delivering several benefits. The main ones would be less spending on maintenance and installation and also a notable reduction in noise and threat to birds passing through the wind farm.
“It promises to be around 30% cheaper than conventional turbines. Furthermore, these turbines are capable of operating in locations with lower wind speeds, where conventional generators would not be effective.”
Caneppele comments that the company responsible for these turbines, Vortex Bladeless, is already testing 100 pre-commercial prototypes, analyzing the viability and potential application of this technology.
