I'm very interested in the small-scale residential application of this.

That thing's cool.
Reminds me of the opposite of a ribbon speaker |

| You see this sort of thing all the time. Not saying that it won't work, but most alternatives never amount to anything. Once again, I'll believe it when they start selling this thing in large quantities. Until then, it's a scientific curiosity. |

The guy who invented/designed this thing seems to have a good track record.
And his intention was to make something simple and inexpensive for under-developed parts of the world. It may never power your electric car but it might make for a few hours of light or radio in a village high in the Himalayas. |

I think the orientation of the band might be a real problem. Getting the flow to hit it correctly that is. Could be useful along roof peaks and such where large mechanical interference already orients the flow however...

I am sure some clever engineer can design it to swivel to catch the most wind possible based on direction of the wind. |
I'm not a clever engineer and I can see an easy solution.
Pivot the frame, top and bottom, and stick a rigid vane on the top. That will cause the frame to face the wind. Just like wind gens do.

One problem that I've read with this device is that the mylar 'ribbon' might not be long lasting.
That's not a big deal on a small scale (think small village in Booneyland). As long as the ribbons are cheap then someone can switch them out.
Might be harder to do on your roof. (Sure as hell would be on mine.) |

| It does look like the ribbon won't work well if gets wet or loses elasticity. |

Mylar? Wet?
Might loose its elasticity, might stretch over time.
If so, tighten or replace.
This is low, low tech. Designed to be maintained by just about anyone. |

They does?
And here I am, thinking that the blades go 'round and 'round.
Who knew they jerked?

Well hold your finger against fan blades, you feel vibrations right? Because it's not a continuous surface, therefore pulses. I don't know if it would make a difference, but it might.

I suppose you mean "hold your finger really close". Holding your finger against fan blades, well, you'll feel something all right. ;o)
I suspect that what one would feel by holding their finger close to the blade is a higher pressure area coming from the blade area close to ones finger. Get a bit away and the pressure will have dissipated, I suspect.
I'd be surprised if there was some sort of intact burst of energy a distance from the fan.
Non-the-less, you might be correct.
That said, don't you think this guy has done some 'real world' tests and not relied on just fans? Wasn't he most likely just making a quick demo and it was easier to turn on a fan than to turn on the wind.... |
