An expensive gimmick...

As for heat, not terribly sure if that would be effective as you would have to heat up then cool down the device so it can be touched. All that in less than 90 sec? Put your oven to 100 C then stick a metal object in it for 90 sec, then take out and touch it with bare hands.... Not to mention some would survive.

UV remains the most viable killing method in this day and age, other than employing some sort of Star-Trek like tech....

But you know what, I can see private hospitals buying into this big time. There are no issues with money and if they can show their clients the level of commitment this shows to the layman, im sure they can pass on the cost quite easily while making a profit.

I can come up with more, but I'm lazy and its Saturday.

As for "The right thing to do". It was, but that was not the reason the US Government at the time (not the people so much as always) had gone to war.

"It is a popular misconception among Americans that the US voluntarily entered WW2, at least against the Germans. In fact, the US didn't. The US entered the general war as a result of the attack on Pearl Harbor. But the US entered against Japan and did not, repeat not, declare war on Germany." http://wiki.answers.com/Q/Why_did_the_US_become_involved_in_World_War_2

That was my "quick Google" attempt.

Don't get me wrong, Americans are a good people in my book, but they blow their own trumpet a bit too much. All governments on earth are screwed up to some degree, America is one of the better ones.

I agree with you that US only entered WW2 due to pearl harbour, but I'm curious, would you prefer a Russian or German Europe to what it is now? And if anything Japan showed US that it is not untouchable.

US profited big time from WW2 in various ways, I'd say that European countries (UK included) have more than paid their debt to the US by now.

What I'm trying to say is that the world of politics is a little bit more complicated than "I helped you, be grateful". There are a lot of fingers in the same pie, I'm absolutely sure than the US gets more than their fair share.

I'd also be careful what you wish for. Despite appearances, European economy is a lot larger than US Economy. US needs Europe more than Europe needs US. And we all need China and Russia more than most people realise.

So how about we all try and get along without bickering about who helped who 70 years ago. It's starting to sound almost as bad as complaining about the crusade.

Did you actually look up the keyboard or do you think its back-lit with UV???

As per the article you linked, "significantly higher" could just mean x2 or x3 more than a regular cell which is designed to cope with little to no UV at all. The article you mentioned a maximum sample height of 41km, which is still inside the ozone layer (right about at the point UV-C is absorbed) http://en.wikipedia.org/wiki/Ozone_layer . I think 2 lamps designed to pump out UV-C is going to beat our sun at that height within the atmosphere (I could be wrong).

Also, life evolving to survive in such hazardous conditions rarely does anything other than survive. Meaning if it is put in a different environment it dies. These colonies may actually need some ozone within the cells to survive and reproduce (after all, they swim in the stuff), something that does not naturally occur in hospitals.

I suppose that 66% is automated, after every user.

As opposed to the user having to remember to throw the disposable top away after use. You may as well make nurses type in latex gloves that are binned every time you walk away from the computer. That's even cheaper, but few will do it, making it less than 66% effective in the end...

However I see you point about the expense, but from a different angle. Now that the keyboard is 66% "safer" should they be investing electrical appliance switches that are bathed in UV after every press? Or door handles? Or anything else that a nurse will touch after/before using the computer.... The keyboard is not the only thing different people constantly touch.

I suppose you have to fight it somehow, but I don't see how you can 'win'.

And only UV-A reaches earth and gives you sun burn.

The Earth's ozone layer blocks 99% UV. Of that, 99% is UVA.

Its the UV-B (0.001% of UV that hits earth and reaches the surface) that causes damage on a molecular level. This is bad for big molecules like DNA.

Cells already evolved a repair mechanism for dealing with UV-B to deal with the meagre levels that does reach the surface.

UV-C is even more nasty than UV-B and none of that reaches the Earth's surface at all

These lamps are pumping out UV-C and UV-B to disinfect. So the cells ability to repair is completely overwhelmed... A bit like having a fire extinguisher to fight a pyroclastic flow...

So, no we don't have to worry about cells evolving, but not because the human-produced lamps are 'meager'.
