CO2 increase of 400ppm decreases cognitive function by >20% [1]
I frequently send this medium article [1] to friends + family for a basic dive into how CO2 affects our thinking and abilities at various levels in common areas.
The article cites a study [2] which graphs cognitive score for different activities at different CO2 concentrations. Each activity's cognitive score is worse at higher CO2 concentrations, EXCEPT "focused activity" or "Information search" (up to some point)
Agreed, this protein target is high for likely many people.
Results from this meta-analysis [1] says
> protein intakes at amounts greater than ~1.6 g/kg/day do not further contribute RET [resistance exercise training]-induced gains in FFM [fat-free mass].
Said more plainly: if you're working out to gain muscle, anything more than 1.6g/kg/day won't help your muscle gains.
For those curious about why, see Figure 5. Americans also get too much protein already, ~20% more than recommended [2]. There are negative effects from too much protein (~>2g/kg/day) like kidney stones, heart disease, colon cancer [3]. Going back to the 1.2-1.6 g/kg/day range, this can be a good range if you're already working out, so get out there and walk/run/weight lift/swim/bike!
>So top of the list for us, of course, designing this thing is safety.
Funny issue I learned after talking to a founder at a similar company: although the battery packs were certified safe for cars (passing crash tests, wild heat differences from AK to AZ, people sitting on top of the battery packs in the car)
... the founder had issues re-certifying the batteries for safe use in a static location for grid storage.
The certification process treated his company like the batteries were made from scratch even though they used the same BMS/coolant lines/etc. already proven and tested.
It's clear you still need strong safety regulations and practices in the rare case there's an event, but the founder noted the grid storage industry regulations were adding redundant safety testing and slowing down adoption. The founder also added it's difficult to compete on cost even with effectively free used EV batteries in this startup space of grid storage against the low cost of Chinese made grid-specific batteries due to the added testing + custom hardware + space constraints and other items. (Caveat: I didn't fact check any of their statements)
Also a cape wind proponent here, I got carried away with my comment below reminiscing about the "just one more year" feeling for cape wind for the past 20 years.
My wind energy professor[1] assigned everyone the task of arguing against cape wind as one of our assignments (and later, for it). Of course, we found a few valid arguments for and against, but enormous reasons for it. The professor had a despondent take on utility scale wind, even though it was environmentally + economically viable, partially from the decades of fighting against the often irrational public perception.
Example homework:
"Wind turbines will block our sunset"
> no, dune grass will block more of the sunset for you, many turbines won't even be visible (insert math)
"Wind turbines will be too loud"
> no, they're so far away from shore that even your breathing is louder (insert math)
"They won't make energy cheap enough to reduce costs"
> no, even using conservative payback plans and limited life, it still works (insert math)
"The native's sunset ritual will be ruined by the wind turbines"
It's less about a conspiracy against renewables, you start to feel this conspiracy for pro foreign fossil fuels in the Boston area.
The iconic Citgo sign, core to Boston's image [2]-> maybe
The iconic Rainbow tank for liquid natural gas[3] -> maybe maybe
The fact that Boston receives tanker ships of LNG from Russia[4]-> maybe maybe maybe
[1]I have a Wind Energy Certificate from my university education, but this was not my focus
