Speaking of cool Canadian stuff in metal boxes....The company I plan to buy my cedar hot tub from (you know, soon, right?) now has heat exchangers that will cool and or heat so it can be a cold tub too (but not at the same time wiley)! Well, they range in size and cost three or four thousand each (not to mention the cost of the rest of the tub). Anyway, that doesn't seem expensive. And they can't detect the virus that causes covid. So no, Biocloud isn't overpriced (especially to sell to the US government which notoriously overspends). Things are looking up.
