Comment Yes and no (Score 3, Informative) 47

Generally speaking, yes... so long as you are still within the effect range.

The germicidal effect comes from an absorption band in DNA. This is (like everything else) a bell curve, where the effect drops off either side of the peak.

This diagram is a good visual.

Note that commonly available UV emitters (including UV lasers and LEDs and the quantum dots mentioned in the article) are so far out of the effective range to be completely ineffective.

And anything that is effective is pretty dangerous to use, so be careful taking one apart.

Comment About 264 nanometers (Score 4, Informative) 47

Peak effectiveness for sterilization is around 264 nanometers. DNA has a specific absorption at that wavelength, so light at this frequency destroys DNA.

This wavelength is in the UV-C band, which is the radiation blocked by the ozone layer, which is one reason people are concerned about ozone: it protects us from DNA-damaging radiation.

Mercury emits UV at around 254, which is close enough to the DNA absorption peak to have good effect. A fluorescent bulb without phosphor and UV-transparent glass will work.

The wavelengths cited in the post, 377nm, are too long for germicidal effect. If the work can be extended, it would result in much more efficient germicidal bulbs by generating wavelengths closer to optimal, and because quantum dots are generally very efficient.

You can get UV bulbs for your furnace that stick into the plenum and disinfect the air as it blows past. You might be able to run one of these from an inverter while hiking. Be sure to cover the bulb and be *very* careful not to look at it when it's on.

Hmm... maybe someone should start up a spin-off called LobbyRoad where politicians can meet to trade kickbacks and favors in an anonymous setting?

Another option is to just tax all money transactions. Anytime money changes hands just charge 0.1% or something like that. For the poor, they'll end up paying an unintended 0.2% tax on the money they make and spend. Something like the financial sector will pay a much higher effective rate, and that is something like a third of the economy.

I support fully. I even posted it on /. a few times before. If we taxed all transactions a nickel, we could raise as much money as we do now, while at the same time limiting the sting of the taxes. When you include bank transactions (think all those HFT bankers) its enormous

and heres how it really works

For example, start with a lump of iron ore.
Bob digs it out of the ground, sells to Pete. Pete pays the closest to a traditional sales tax, cause the value added is the value of going from nothing to something. Pete smelts it into iron, and sells it to Bob.
Bob pays tax for the value added to the lump by turning it from a lump of ore into a lump of metal. In addition to adding in the cost of the tax paid on the lump initially.
Bob works that iron into a shovel head, and sells it to Bob. Bob pays tax for the value added by turning it from a lump of metal into a shovel head, in addition to the cost to make the iron, and the price to dig it up. (which he then uses to dig up more ore).

Hahahaha more powerful than having the source code,

Do you never tire of beclouding yourself?? I suppose not...
Well for the MENTALLY SLOW HERE I WILL EXPLAIN IT REAL CLEAR LIKE.

On iOS, you can easily change the OS AND APPLICATIONS.

On Google you can only change easily what you have source for, which is the OS - not applications.

So I'm pretty sure even the most addle-braned can understand one is greater than two...

I leave any response to your own fevered mind, I shall not read it.
