Wind-powered racing car

Tamiya and Loopwing have unveiled a plastic toy car that is powered by electricity supplied via a wind power generator kit. Some assembly knowledge is required before you kick things off, but it can’t really be that hard, could it? The entire bundle consists of a couple of gears, a capacitor, a small steering module, and a wind powered charging station in addition to the said car. It takes approximately 5 minutes of strong wind to provide the tiny car with enough juice to run around for 3.5 hours before being exhausted. Do you think this toy will sell exceptionally well in Holland? At $30, it looks like a potential stocking stuffer candidate.
