News / Nuclear Power in Poland? Yes, please! Absolutely nobody disagrees! [73]
There is common thing between "green" freaks - once they beleived in something, they not spending their time to research consequences, they starting their missionary job immediately. ;)
Well. Lead is poisonous. "Green" freaks was unable to pass by... Their RoHS initiative already passed into law. Now electronics manufacturers cannot use any lead-containing solders or components. But, unfortunately, pure tin is not usable as solder, it produces microscopis whiskers that cause short circuits on PCBs and at low temperatures slowly transforms to gray powderish substance. So, lead-free replacements of well proven 63Sn36Pb eutectic alloy now in use - and it is MORE TOXIC than original one due to added Sb, Cd, etc... In addition, higher melting temperatures and not so good adhesion of lead-free solders create a lots of problems to manufacturers and shorten average life of electronics (creating additional waste) - but who cares? They won their battle with lead, they really happy!
Another beloved toy of freaks is "carbon footprint".. Will not comment on this...
Now, when I heard that someone tries to say that "everyone should do at least something to protect environment", I always want to say that safest thing that he/she can do is to kill yourself. ;) This for sure will not create any additional harm to environment, will save a lot of resources, and specialists whose work is to determine safety of something will work under slightly lower pressure from crowds that didn't understand what they really want to do. ;)
Oh, Poland could go for the tidal waves! What tidal waves? The Baltic sea tides are perhaps the same as the thickness of a hair. OK, a pubic hair, but that's still not enough to power the country.
