Are there any other methods other than drip, percolator, french press?!

I think what you're talking about is a vacuum coffee system. Bodum actually still makes one, recently revived, but the ones from Northwest Glass are cheaper and look a lot cooler.

The working principle of a vacuum coffee system is based on the expansion and contraction of gas (water vapor). Water in the bottom globe is heated, creating hot steam which essentially forces water into the air above the water line as well as causing those molecules to move much faster, thus expanding the amount of space it takes to hold the same amount of matter. This causes the water below to be displaced, and the only place it has to go is up the tube, through the filter to where the coffee grounds are. At this point the heat source is turned off, allowing the water vapor and air to begin to cool and contract, the resulting suction then causes the water that was forced up to come back down, now full of caffeinated-goodness :-)

This is similar to but not the same as a coffee percolator which doesn't use suction to force the coffee back down (hence the name vacuum coffee system), but instead uses convection. A percolator forces heated water up a tube through coffee grounds in much the same way, but then there are holes in the basket which contains the grounds and the water escapes through them. Meanwhile cooler water continues to fall, get heated, rise, and the process continues.

There's also a cold water coffee dripper which slowly, in your fridge, allows water to drip through fine coffee grounds apparently creating a more mellow but still full-flavoured brew which is good for iced coffees, cooking or baking. I just came across this and am now very curious. I wouldn't buy one for $265, but you could probably jerry-rig something with an IV drip that would also look pretty cool. You'd probably get some reactions when someone asks if they can grab a beer from the fridge.

theres the vacuum method thats coming back into popularity. The Italian Vespa pots, those wasp waisted two part aluminum thingies. They make good coffee by the way. And then there's cowboy coffee. You need a campfire, a two gallon bluestone coffee pot with percolator gurts removed. You fill it with water and set it on the fire. then you add 1 lb of ground coffee. when it starts to boil you give it a minute and either A: crack an egg into it, B: drop a handful of eggshells into it or #3: drop in a yellow onion, whole. You set it on the rocks next to the fire and then man up and pour a cup. Oh yeah, the egg tricks are suposed to settle the grounds. What the onion does I have no idea. Makes the coffee taste bad, I do know that. Highly optional, the onion. As the day goes on and the coffee level drops you just add more water and returen it to the heat. This is coffee that will grow hair on chrome. It is best drank with copious amounts of real sugar and carnation canned milk.
It's funny, as I sit writing this I'm drinking French roast made with a gold plated filter out of a WWll Submarine captains mug. MM MM good!
But...on a -15 degree morning sitting at the campfire waiting for daylight......cowboy coffee definitely the kickstart that is needed.
