Comments I have an idea how you can keep constant pressure in the fuel tank without any complicated moving parts. The main fuel reservoir is an air-tight container. A tube reaches into a small cup-shaped pressure equalizer located lower than the main fuel tank. Air pressure keeps the fuel level at a constant level in the equalizer as more fuel can only enter it when the fuel level drops below the connecting tube to the main reservoir and air can enter it. Take care, Christoph

Comments Neat! Just discovered Make magazine. I admire the cleverness and laid-out-plain workings of this simulator. Far better than software where, even if it's open source, seems like made-up magic. May many of these be built and basic flight physics grokked! BTW, i was in CAP, way way back in 8th/9th grade.

Comments Part 2) [alternately titled: Character cap passed] This is the same manner that my carpet cleaner uses to push the clean water to the top feed on the water bucket. You put clean watter into a bag that is suspended in an open container, and when the machine sucks up used water, it puts the water into the outside of the container. Therefore the water outside the liner is pushing the water inside the liner towards the center, causing it to move up. I have a Bissell, if you want to look at it in the stores, similar to the Bissell Powerheat series http://www.bissell.com/Products/Product.asp?catalog_name=BISSELL&category_name=UprightDeepCleaner&product_id=7901+CVUDC, and the part you want to look at looks like this http://www.bissell.com/images/Products/0159041-L.gif which is part of this http://www.bissell.com/images/Products/0159043-L.gif

Comments The MAKE article mentioned trying to think of a way to force the pressure on the feed but only allow so much water to recycle into the actual original tank or limit the amount of used water so as not to have an infinite fuel supply. I think I have the solution. In the top of your energy reserve tank, insert a thick mil garbage bag, and line the tank with it. Now, tape two sides of that bag in such a way that the tank is lined when empty. Preferably the rear side and either the left or right. Now run the hose and pump from your energy sink tank into the garbage bag, and when it's time to "refuel" the sim, use the pump to cleanly move the fluid from inside the bag to outside the bag (that's why I said only secure two sides, so you can fold the flap back, and so it has room to move up and down without creating a vacuum). Therefore as water enters the lined area, it's not refueling the tank, but it is supplying pressure back into the feed system. This is the same manner that my carpet cleaner uses to push the clean water t
