Yeah - I'd love to have the geothermal heat pump, but I just have a regular one that exchanges heat with outside air.

There's not a lot of heat to be pulled from the air when it's 5F outside. My electric bills were atrocious this winter from using what is effectively a giant toaster inside my air handler to heat the house. I'll be having someone coming by to "weatherproof" the house this summer in order to try to increase efficiency, but I'd love to put a nice whack of PV panels on the roof, and one of these batteries on the wall next to the electrical panel and water heater in my utility area.

And as noted by others in reply to your note from others, your own fucking wayback machine link states:

"Even under ideal conditions, Apple Watch may not be able to get a reliable heart rate reading every time for everybody. And for a small percentage of users, various factors may make it impossible to get any heart rate reading at all."

Clearly, having a tattoo counts as one of the "various factors"

From your own god damn wayback machine link:

Even under ideal conditions, Apple Watch may not be able to get a reliable heart rate reading every time for everybody. And for a small percentage of users, various factors may make it impossible to get any heart rate reading at all.

So they just added another point of detail. It clearly says that it won't work for some people, and apparently people with wrist tattoos are included in that set. Try again, yourself.

When the profit is $0.70 per can, you're still looking at being +$7M at the same volume. And, if this change does what they're hoping, which is to preserve sell-through and maybe increase market share against competition that is still using aspartame due to whatever consumer belief may exist, $200k is a tiny investment for growth.

Unless you're soaking in a hot tub that is:

A. actually using chlorine (most use bromine because it's much more stable at hot tub temperatures, doesn't cause people's eyes to burn, and doesn't fade bathing suits) and
B. being Dichlor-shocked while you're sitting in it,

you're talking about a concentration of 3-6 parts per million if the maintenance is being done properly. It's enough to kill off single-celled organisms, but not enough to do jack shit to your skin.
