	RAFT System for Vegetables
		In the typical float bed system, the plants are in trays floating in the water and the cells of the trays are saturated with water constantly.
		In the RAFT system, an absorbent fabric, known commercially as capillary mat, is laid over the floating polystyrene trays with about 2" to 6" of the mat hanging down in the water all around the raft of trays or insulation board.
		The key to success with the RAFT system is that growing medium in the pots placed on the surface of the float table have good contact with the mat.

	Floating raft system - Wikipedia, the free encyclopedia
		Floating raft is type of foundation, invented by John Root, that protects against settlement and the Soil liquefaction of soft soil due to seismic activity.
		It was a necessary innovation in the development of tall buildings in the wet soil of Chicago in the 19th century.
		For a floating raft foundation, or floating foundation, the foundation has a volume such that were that volume filled with soil, it would be equal in weight to the total weight of the structure.

	RAFT System for Vegetables
		The RAFT system uses a commercial growing medium that allows the water to be wicked up through the bottom of the pot from the mat.
		The RAFT system allows the seed to stay constantly moist, not water logged, and not dry out during the germination process.
		The RAFT system allows a fertilizer to be placed in the water so there is a constant supply of nutrients to the plants.

		Hasan and his fellow seaweed growers use the floating raft system, with the seaweed remaining in the water regardless of tidal changes.
		The raft is then towed to a suitable farming area along the coast and fastened to iron stakes driven into the seabed, stones, or other materials to keep it in place.
		The seaweed hanging from the floating raft benefits from an uninterrupted flow of nutrients and is not directly exposed to sunlight.

	Improved Float Bridge (Ribbon Bridge)
		The term "assault float bridge" is strictly a colloquial term generated by years of not utilizing the proper name for this bridge.
		The ribbon bridge is a modular, aluminum-alloy, and continuous floating bridge system consisting of interior and ramp bays that are transported, launched, and retrieved by a transporter/launcher vehicle.
		Ribbon bridges and rafts provide the maneuver commander with a reliable and responsive means to cross wet gap obstacles from the march.

	Rafting
		Rafting has become highly specialized, with designs and equipment for different conditions, from calm water paddling to extreme whitewater rafting.
		Barefoot feels great inside the raft, but you should be prepared to be walking on river bottom in case of a spill or when getting out of the raft at streamside.
		This allows a floating child to be pulled back into the raft easily by the collar handle; the crotch strap ensures that the child will not slip out of the life jacket.

	Conservation Ecology: Sustainability, Stability, and Resilience
		If a weight is added suddenly to a raft floating on water, the usual response is for the weighted raft to oscillate, but the oscillations gradually decrease in amplitude as the energy of the oscillations is dissipated in waves and, eventually, in heat.
		Such a system is not suitable for a discussion of possible collapses of natural systems, since such collapses are excluded by assumptions such as (Eq.
		There is a mathematical theory that shows that systems such as (1) are good approximations to general systems with a stable equilibrium, but that theory implies that the approximation holds only in the immediate vicinity of the equilibrium, i.e., that the approximation is valid only locally.

		Either a pump system w/ a pressurized discharge onto the water surface, or some type of mechanical agitator sitting on the surface, or other designs that introduce the ambient air into water circulating in a system.
		Floats at first until the last 2" of nutrient is used, then roots hang in the air, just a mod to improve oxygen intake, I know of instances where floating is all the way down.

	HOW TO BUILD
		The wick system is the simplest of all hydroponic systems.
		A raft system is a floating part(usually styrofoam) floating on a container of nutrient with the plant roots extending downward through a small hole or cup, or other container held by the float.
		An aerator is usually necessary in a raft system in order to maintain oxygen levels in the nutrient high enough for healthy plant growth.

	Sevier Thrust System - Utah Geological Survey
		The thickened thrust wedge overloads the earth’s crust, which flexes in response, similar to loading rock on a wooden raft floating on water.
		The Sevier thrust system is a typical thrust system consisting of, from west to east, a thrust belt, a foredeep basin, a forebulge, and a back-bulge basin.
		The tremendous load of the stacked plates depressed the crust under and in front of the thrust belt (visualize forcing down the end of a raft floating on water by loading it with rock) forming a “foredeep” basin into which thousands of feet of coarse synorogenic sediment was shed.

	Microfarm Newsletter: This Issue's Project: A Raft System
		On the site, the author provided instructions for what I now know is called a "raft system." It involved cutting some holes in a sheet of Styrofoam, floating the Styrofoam in a container filled with water, and sticking seedlings into the holes.
		My mind was quickly changed about a year later when I saw a picture of one in Growing Edge magazine, and I learned that this technique is actually very widespread among commercial growers, especially for the cultivation of lettuce.
		I've since built many raft gardens, and the results have been great, but at the risk of sounding cliché, the raft garden's greatest strength is its simplicity.
