Plunger Toilet   (+6, -1)  [vote for, against]
Airtight toilet lid incorporates plunger to flush contents.

This idea is the opposite of the Load Capacity Determining Toilet. The former proposes to use technology to ensure the plunger is never needed.

Instead, I propose to ensure the plunger is ALWAYS needed. The toilet lid is airtight and incorporates an air plunger with a one way air valve. To plunge the toilet, either the human or an air pump pumps air into the chamber, forcing the contents of the toilet down the tube. After completing the flushing operation, only enough water to refill the toilet to the desired level is added.

This method uses an absolute minimum amount of water, and the human powered version consumes no electricity either. Also, it forces men to lower the lid after use. (Actually, it doesn't..but ewww!)

This toilet is suitable for use in portable systems such as on RVs and other places where running water is limited/unvailable.

I like it. I'm not going to go look, but there may be something like this in old submarines, maybe. [+]

I like it. But what if there is an air bubble down the pipe? And you apply greater and greater pressure, compressing the bubble, but the contents just won't flush? And then you have catastrophic toilet-seat-seal failure?

Because of the one way air intake, you'll be progressively pushing more and more air into it. Sooner or later, the blockage is going to flush away!

As it is, there should be an air bubble in normal operation. The way existing toilets blocks smells from the sewage system is a pocket of air in a curved pipe section. This doesn't stop plungers from working (but of course, existing plungers lack the one way intake valve so they're not very efficient).

You could make tea with it as well. [+]

Not sure why air would be preferable to water. The pump idea has been around for a long time in marine toilets, both manual and electric. [link]

There are marine toilets with sealable lids, but they use suction to pull through fresh water,rather than positive pressure to push through waste. I assume you'll be screwing the toilet lid down every time you flush? The consequences of a toilet seat seal failure would be pretty, er, redecorative.

The russian roulette involved in the "Toilet seat failure" adds a sporting element to toiletries.

Good work. I award you my first muffin!
