Yeah, something more like a shell filled with explosives, something that would fragment and cause damage when the C4 inside explodes. The image on the link is for comedic effect I believe.

The image fits the literal wording of the question pretty well I think, but perhaps not the spirit of it.

True, but then again, the turbine on the rain gutter is not accurate either. Why is the turbine attached after the gutter curves outward, as opposed to free falling water? Where Mr. Wright? Why can't I find Mr. Wright?

Outstanding!
My favorite is the C4 strapped to a boomerang.

The way he computed the elctricity vs. rain is quite mysterious. Somehow, the quantity of falling water transforms into kWh, but how ? I assume it is simply the work value of the falling water weight turned 1 to 1 into electricty (which actually assumes a efficiency of 1 from the turbine).

You're right - it is a matter of energy transformation. The potential energy given up by the water in falling from roof height to ground level is transformed into electrical energy, less the losses in conversion. That's where it all falls down (pun intended). A rain gutter downspout is rarely a full pipe, if ever, and probably always a turbulent flow. Turbines are best operated using laminar flow, and even then are probably less than 70% efficient. I'd expect a conversion efficiency of less than 50% in the best of times, far less most of the time.
