"We found that when people broke the rules, teams were less likely to win games."

This seems like a prima facie bad conclusion to their hockey study, considering that the Panthers won the cup while being effectively tied for the lead in penalty minutes, with #3 not being particularly close. Yes there's a weak correlation between penalties and losing, but considering that the absolute best teams usually have a high rat index, there's a big lost opportunity to go into the rat factor in hockey and how it translates to the corporate world!

if this is due to that specific manufacturer having battery fires, i don't hate it as it seems like the battery replacement option is basically the same as a recall. completely different from a random bug causing it or an across-the-board EOL update. pixel longevity isn't great, but at least they're relatively easy to maintain and the device protection program is acceptable.

This isn't really accurate, they're targeting industrial wastewater yes but they are working with and have tested brackish water up to several thousand TDS. They had a working EDR system for drinking water installed in Gaza until relatively recently and several in India as well. I'm also skeptical they can make it work with seawater, but it absolutely works with undrinkable brackish water in many other cases too.

This is a questionable way to present what's an excellent project and hopefully soon to be commercialized technology. The big deal here is it's a presumably installation ready application of EDR for desalination instead of RO which most systems use. This is a big deal because the membranes use electricity instead of pressure as the filter, which means everything can run at low, normal plumbing, pressures instead of the crazy high pressure RO stuff. For seawater it's borderline whether or not it will match RO for performance, but for lower salinity groundwater and industrial wastewater, it should be significantly higher performance for the same power as well as lower maintenance and capex.

The no batteries thing is basically irrelevant to the innovation, and in fact Genius Water already offers no battery RO systems, also with questionable benefit (as well as being difficult to work with).

I run a solar and water focused EPC in East Africa and will hopefully be working with these guys in the future when they're off the ground with a commercial system. The potential is extremely high, particularly if the maintenance overhead and operational complexity can come down in practice.
