My cousin bought a crappy electric supercharger the other day, and I must say it looks like a piece of crap. There is no way these things can work, right?

If you spin them up to ~100,000 rpm, maybe. Otherwise, they're just noise makers. The law of conservation of energy says its extremely hard to do, as any load on your electronic system will make the alternator harder to spin. Because its only XX% efficient (not even close to 90%), same for the eSC's motor, you'll have to draw lots of power from the battery to see any gains. Essentially, you may produce a couple more HP from a tiny bit of boost, but all gains are a wash since the alternator needs that much more HP to spin it.

IMO 0.5psi is not worth $29.95 + $69 s&h.

Actually Thomas knight makes an electric supercharger and I'm not talking about that stupid E-RAM thingy...it would actually run off a modified charging system with maybe multiple batteries...like the ones they use on high powered stereo systems.

As long as you don't mind only having 15 seconds of boost before you have to recharge the batteries.

that's really only a DRAG Race friendly setup.
capacitors, extra batteries, and 10-20 seconds of boost.
definitely not really useful for a street or roadrace car.

for the money might as well just get a JRSC setup.

The only problem with that unit that uses a root-style blower is that airflow doesn't change, so you see boost decrease as rpms increase.

Seeing as how it costs a lot, requires more maintenance, and adds more than a jrsc... I can't really see a big benifit. For a car that would be impossible to make a blower manifold for, maybe, but not for a honda.
