It's not brightness but spectral irradiance that matters. You need to compare the spectral irradiance curves for the sun at the earth's surface and that of a welding process that a welding filter is designed to block. Only public ref I can find is this which shows some significant UV radiation around 250nm greater than 0.5 W*(1/m^2)*(1/nm). The earth's atmosphere cuts out most of the hard UV, especially at sea level and times away from high noon.
So, in fact, welding radiation is more dangerous than the sun since the earth protects us.
A similar solution is to use a bluetooth to POTS adapter. Xlink makes a few, for instance the Xlink BT Bluetooth Gateway. Locate the gateway where you get a good signal and run a landline down to your basement. Never tried it, but it's got passable reviews at Amazon.
I'm a "Slashdot libertarian" and I think heroin should be an Over-The-Counter drug. Buy it. Take it. I don't care. Go whine at the Slashdot Reagan-Youth leftovers, but don't blame the Libertarians.
The song "Box of Rain" is actually about a son (Phil Lesh) dealing with the slow death of his father. The lyric "What can I do for you to see you through..."(sic) is a lot more personal that just a bunch of hippies sharing dope in Haight-Ashbury.
The B.C. transportation device is known in the
unicycle community as an "Impossible Wheel", see
this
dangerous toy. It's just a wheel with flat pegs on bearings.

GE and DeBeers got together to fix the price of industrial diamonds back in the early 1990s.
Yup, it's by Eisenfunk. Pong: http://www.youtube.com/watch?v=cNAdtkSjSps
