Can someone invent these?

My current anime obsession is 'Getbackers'. One of those shows where you have very humane super humans. Its about a couple of guys who start a retrieval agency and all their friends and foes. As I watched the show I realized that it would really be fun and profitable (not to mention the service to mankind blah blah blah!) to actually mimic some of their powers in the real world. For example, Ginji's power to generate electricity. Of course we cannot generate electricity buy a shock producing glove that can be turned on at when needed should be great to fend of men and women who lean too closely to us with harmful intent. Dr. jackal's bloody sword could be a dangerous thing but his pesky little knives can keep muggers at bay. Himiko's monkey poison will come in handy when the neighborhood not-so-friendly thieves decide to pay a visit. And it would really be fun to use Ban's evil eye on nasty auto drivers who think people equal to bags of money that can be tossed around during the ride and fleeced after that.

In-fact we can create Ginji shields that provide an electromagnetic shield around our vehicles that will slow down other vehicles that speed in within a few feet. Imagine the number of accidents that can be averted (well, at least I think so).

hum, if only I was good in physics, I would at least know if these ideas were hare brained. Unfortunately, even today, I find it difficult to believe that I actually passed that subject in high school.
