R2000!!?? Holy crap--just go back into the womb!!! I don't see howmuch of Canada needs that-especially in the south Ontario area-you guys are usually warmer then my part of PA being lower elev and having the warm lake, etc
HRV sounds like a 'good; thing for efficiency, but unless you have a really kickass filter-- like laced with phages or with a UV light--it is bad for constantly recycling bacteria. New buildings in the US have closed hvac systems to save energy money- In places like office bldgs, apartments, schools-all the ppl report having more bacterial (airborne) infections and allergens
It is a good idea but a little fresh air can not hurt anyone
Did the guy who came up with this watch BOY IN THE PLASTIC BUBBLE (A Travolta "classic") and become scarred for life?

One cannot use the 'blanks' used in a rifle (well you could but it would be very stupid) and you would be equally stupid to fire a real round. Since the spring has to be engaged against a solid surface to "fire", you really couldn't use it has a weapon
I have one that you strike with a hammer- the models with a pull trigger-that I have seen-have the same safety to prevent it from being used as a weapon as well
Are all of these permits and licensing for collecting revenue, or actually ensuring safety or both?
