those links are about stuff going on in red china and i'm not sure they can be trusted coming from a country that has yet to 'fess up about june and the other two links are in the hopeful class they have lots of ads seem to have little info and are a bit difficult to downloadnews sources generating revenue in the st century huh presumably there are many stick and concrete houses built with and without such additional things further both stick houses and poured concrete houses have been with us for millennia and decades and if a lack of the other things were issues they would have been long noted given the hucksterism of much of the emerging technology talk i don't think it's being too pedantic to describe if they have these other things or not
