The dish is composed of a set of 10 inch by 12 foot curved mirrors, like the one seen here. The students easily mount the mirrors to the aluminum framework using simple hardware like washers and zip ties.  (Source: MIT)

The mirrors incredible power makes short work of a beam of wood, disintegrating it in flames and smoke. The focal point can melt steel.  (Source: MIT)

And they call wind turbines bird-killers?!

What would happen if a bird flew in front of that? Mmm... roasted duck.

I doubt it can convert ANY bird to a roasted DUCK :)

And that's exactly why they'll try and stop this too...

Slightly more legitimate concern: If there a lots of little fields of these around the country, what do they look like from above? Ie, 500ft and higher.

Pilots can't exactly help but to look at the ground, and if it's really right at that distance, well.. you don't have to look directly at the sun to be hindered by it.

Not that its a show stopper.. if it's cheap and highly efficient, then perhaps it would just be something indicated on aeronautical maps as a navigational hazard. Again, if its a concern at all.

One would assume the point is to aim these at some medium on the ground to extract energy, meaning if a pilot got the sun in his eyes they're doing it wrong.
