  1. [TT4] I’ve has this thing about rogue waves for a while, probably from all the nautical-themed reading I’ve done over my lifetime. This was fascinating that the cross-wave angles have to be exactly right. It’s almost reminiscent of harmonic signature having to be just right to break glass. From the linked piece consider the first recorded rogue wave from an oil platform, that in 30+ foot seas recorded an 84 foot rogue wave. Awesome, terrifying power of the sea. Imagine an 80 foot wall of water coming at you from nowhere.Report

    TT11: The article states “…and analysis demonstrated heavy metals are largely trapped within the brick.” This raises the obvious questions.Report

      I can think of a few obvious questions, like do we worry about kids (or Presidents) licking the bricks?Report

      Until about 10 years ago, there was a sewage treatment plant that used a melter to turn sludge into granular glass similar to the sparkles on a roof shingle. In fact that was the end use. The technology was also said to pack heavy metals inside the structure, and received all of its environmental permitting.

      It was discontinued about 10 years ago because there wasn’t a market for the product anymore, and the state had passed a zoning law that essentially required this particular melter to be located at its landfill, which lost a lot of the economic and environmental benefits of reduced trucking.Report

    [TT5] It sounds like the studies also showed positive results from a compound that appears to block the negative impact of gingivitis on Alzheimers. The studies are early, but its possible that there wouldn’t be the need to brush teeth at all!Report
