pocket ref website

I want a website thats similar in concept to the Pocket Ref books (and other similar to-the-point all content/no filler references).

Then of course, it should be freely available (for the most part, the information falls into “facts”, and most of what doesn’t could probably be found in public domain works).

And searchable. Then the killer app would be to bundle it up into an app for a Palm or Pocket PC.

Just in case you ever need to calculate the velocity of air in pipe. Or know the approximate tensile strength of a grade 8 1/2 bolt. Or the type of household voltage in Iceland. Or the area of a regular octagon. Or the triple point of water. Or the density of carbon steel.

Seems like it could fall under Wikipedia since at least some of that info is already there.
