Inventions That Wouldn't Make Sense

I thought that this would be a fun thread. Here we would post, well, the title explains everything. Here some examples:

Dry Clean Only Bathing Suits
Inflatable Dart Boards
Solar Powered Flashlights


You got any good ones?

A machine that turned red apples into red apples.

a butt scratching, nose picking couch that you can drive

here are some patents for anti-terrorism tactics/devicec that are a little less than brilliant (and yes these are existing patents!):
1. the police dog earphone:
police dogs are a great resource when it comes to terrorists or criminals in general, but if the dog is far away, how can you command it to attack a bad guy?
the police dog earphone!
the problem: If you're too far away to see the dog, how will you know it's near a terrorist?!

2. Kevlar explosion containment net:
cover a suicide bomber with an explosion containment net. it's kevlar so it contains the effects of the bomb.
the problem: you have to get close to the guy to use the net... if he detonates it before you get to him, you're screwed!

3. Airplane sleeping gas system:
terrorists love hijacking airplanes. so let's outfit all commercial airplanes with a system that pumps sleeping gas into the ventilation system...
the problem: Everyone gets knocked out, including the pilots.

4. In-flight passenger control system:
make passengers wear armbands that monitor for signs of stress. There's also a syringe attached to the band filled with a tranquilizer.
Problem: do you really want such easy acces to a bunch of tranquilizers to all the passengers, including the terrorist?

5. Airplane trapdoor:
a trapdoor outside the cockpit which will open to a cage in the lower deck.
Problem: the terrorists have to be on that one area to be captured. if they have bombs strapped on, you're just encouraging them to detonate them sooner.

6. Biohazard suit with built-in toilet:
you put on a biohazard suit to protect from biological threat... but it can take a while for the danger to pass, and in the meantime, you may have to go. so it has a built in toilet. just squat, and a bladder drops out and when you're done, it seals shut.
Problem: no real problem, just... come one, people... *sigh*

7.Mobile crematorium:
if the terrorist is successful in killing you, your body will need to be disposed of quickly...
the mobile crematorium is basically a combustion chamber on wheels.
Problem: it's just as awkward to lug around as a lifeless human body, and after you're cremated, your family can't pay their last respects.

An electricity-powered bathtub.
