The TE items work on vanilla basics without the lag; you can make an infinite water machine using a dispenser and 3 water blocks, but it's laggy and bulky, so the Aqueous Accumulator offers a pricier but more efficient alternative. Same thing with the Igneous Extruder; infinite cobblestone from one lava and one water is available using a block breaker, but TE makes it less laggy.[DOUBLEPOST=1364914597][/DOUBLEPOST]
Ice is solid water, steam is water under the form of a gas. There are some problems with the naming because the different forms were discovered before the states of matter, but non-liquid water DOES exist
