The Press Bot is a French press coffee-maker that fits in a standard-sized nalgene water bottle, so you can make gourmet coffee from your campsite.

Update: Paul sez, "Readers in Canada can pick up a Press-Bot at Mountain Equipment Co-op! MEC Product Number: 5011-315"
Update 2: Joe sez, "Gizmodo had an entry on how the threaded handle of the press-bot exactly matches the thread of most camera tripods. Combined with a filled nalgene bottle, the press-bot makes a perfect makeshift back-country camera tripod. I used this rig on a recent trip to New Zealand and it worked pretty well."
Update 3: Alison sez, "We've taken to using the Aerobie Aeropress when camping instead of cafetieres. Why? Because it's incredibly, hugely, easier to clean: you press out the grounds, then wipe the end of the plunger, and the press is ready to make more coffee. When camping, that's a real benefit."
Update 4: Irma sez, "here's a link on the possible connection between birth defects and the plastic used in Nalgene bottles.
I write books. My latest is a YA science fiction novel called Homeland (it's the sequel to Little Brother). More books: Rapture of the Nerds (a novel, with Charlie Stross); With a Little Help (short stories); and The Great Big Beautiful Tomorrow (novella and nonfic). I speak all over the place and I tweet and tumble, too.
