Spanish company creates bladeless wind turbine

CLEAN ENERGY WITH VORTEX
Vortex technology uses no blades, getting energy from wind through oscillation without gears, brakes nor oil. Its design makes it a nice alternative for a greener on-site generation.
Vortex Bladeless is a vortex induced vibration resonant wind generator. It harnesses wind energy from a phenomenon of vorticity called Vortex Shedding. Basically, bladeless technology consists of a cylinder fixed vertically with an elastic rod. The cylinder oscillates on a wind range, which then generates electricity through an alternator system. In other words, it is a wind turbine which is not actually a turbine.



Vortex wind generators are more similar in features and cost-effectiveness over time to solar panels than to regular wind turbines.

Looks inefficient for generating much power

 

Sort of like the Democratic party.

 

There likely needs to be a lot of development before or if this becomes viable.
In the early 2000s wind turbines were about 1 MW and had reliability problems. Today the sea based wind turbines are 14-15 MW each and last as long as a gas turbine. There’s a lot of technology development required to make these things economical. Wind especially offshore wind has real potential BUT storage technology (batteries) is still lagging. There are some very interesting new technologies including static batteries that are close.
Regardless I believe we will need big block power generation (combined cycle gas turbine and nuclear) always to keep a balance in the grid.

 

Wind turbines kill a lot of birds. I guess environmentalists don't care about birds

 

Not just birds, but also bats and insects.

Which is why a bladeless wind turbine makes so much sense.

 

If they work. That vibrating thing doesn't look like it would generate much power

 

Which produces more energy? Wind turbines or solar panels?

 

This is really cool. Especially once you see pictures of the turbine blade graveyards, this makes a whole lotta sense.

 

For those wondering...

Wind is a more efficient power source than solar. Compared to solar panels, wind turbines release less CO2 to the atmosphere, consume less energy, and produce more energy overall. In fact, one wind turbine can generate the same amount of electricity per kWh as about 48,704 solar panels.
