In one of their videos [1] the mast can be seen vibrating at a high intensity. There is for sure lots of tension in the material produced, I wonder how durable the masts are. I have the feeling they would instantly break during a storm.

Wind turbines have pitch control to reduce the speed of the rotor and blades. This allows wind turbines to survive most storms. I don't see an equivalent control mechanism with Vortex Bladeless masts.

From their FAQ (https://vortexbladeless.com/faq/#question6):

"Vortex wind turbines are designed to have high performance with most common wind speeds (between 3-12 m/s) and to has a quick response to turbulent airflows changes.

If wind velocity exceeds the device’s working threshold, it will stop by itself due to physics principles."
