New bladeless wind turbine

I thought I would share this link.

I have done a little research and think that they would make an excellent DIY project. Easy to build, not very expensive, and low maintenance. The question remains "How much power can it produce"?

Hmm, but where the heck would you find a linear alternator with the appropriate piston length?

Don't know anything about this, but it does look cool. Maybe even could replace the carbon fiber rod with a hardwood.

I was thinking of it like a lever with a two axis fulcrum between the collector and the alternator. The alternator would be comprised of a permanent magnet (as the rotor) at the end of the rod hovering over a pancake coil (as the stator). This should produce a near constant voltage and variable frequency alternating current. A simple AC to DC converter should provide a usable and store-able power source.

I realize that this is very simple description but I have not yet explored the options or details.

I was thinking the alternator worked like those shake flashlights, with the rod connected to a permanent magnet inside a coil, the vibrations of the rod transferring to up and down motion of the magnet.

But you know what, I've got a problem with this concept. When you're close to the ground, most places, you don't get consistent winds. Will the baseball bat (heck if I now what it's called) get to oscillating with intermittent winds? I looked on their site, couldn't find any mention of that problem, would feel better if they addressed it.

Thanks Bryan

At a closer look in this link. https://www.youtube.com/watch?v=WqcNc9bKlNY

I was able to see that you are right, it is a vibration alternator that they use. I am pretty sure that they have to convert it into DC though.

Good point about the intermittent winds being a problem.
