Shane Wright

Seattle and Shane Wright have reportedly agreed to part ways this summer via a future trade. What would you think of the Hawks adding him? Obviously hasn't lived up to his draft slot yet but curious if people think he can still be worth a look at a presumably cheap price.

Recs for Young and Old in/around Rocky Mountain National Park?

I'll be visiting RMNP in early August with my 6-year old and my in-laws (70+ years old). Does anyone have specific recommendations on things to do/see which would be good for that age range? We can do some hiking but nothing too long or strenuous.

[Self] Baobab Waterfall Prison/Power Plant, An unimaginably bad idea.

A submission for an architecture competition gained some attention and got posted to a few subreddits.
https://amazingarchitecture.com/visualization/baobab-waterfall-madagascar-by-ahmad-eghtesad

It's meant to be a prison/power plant (like the electric nightmare prison from Andor)
There are soo many obvious problems with this idea it's genuinely staggering.
The architech who designed it doesn't seem to know how hydropower (or anything else tbh) works and the whole thing would flood with in minutes, as there's no way to get the water out, once it's fallen in and generated power.

However there is a mechanism by which it could "work". The plants within the strcucture can absorb the water through their roots and then transpire it into the air. So if the water flowing into the structure and genreating power is equal to the transpiration of the greenery then the system is in a sustainable equilibirum and could fucntion as a power plant, like the architect proposes.

The render shows tropical rainforrest, however the salty ocean water would kill that immediatley. The best plant for this would be Cordgrass, which is occasionaly used to drain saltwater mashes. According to a 2018 paper by David Miklesh et al. Cordgrass can transpire 5mm of salt water per day.

The strucutre is 13 stories tall, and about as wide as it is tall, so I assime it's hieght and diameter are 180m.
With that we can calculate i it's area (180m/2)^(2) x Pi which is 25446m^(2)
That area times by the 5mm/day of transpiration gives us a total evaporated water volume of 127.2m^(3)/day, or about 1.47 L/s, not exactly enough to have a waterfall.

So that gives us the daily volume of sea water that can "fall" into the structure to generate power.
The hydro electric power equation is fairly simple: Power = Efficiency x density x flow rate x gravity x height.

We'll be (extremely) generous and give the waterfall generator a 90% efficiency
The density of sea water is 1030 kg/m3
Out flow rate is from above is 127.2m^(3) per day which is 0.00147 m^(3) per second
Gravity is 9.81m/s^(2)
and the height as estimated is 13 stories or 180m

0.9 x 1030 x 0.00147 x 9.81 x 180 = 2406 Watts

So as far as I can tell the absolute maximum power this could possibly generate, without external power to pump out the water is 2.4kW. Which is about 8 solar pannels.

Probobly not appart of the green energy future.

What's your favorite place for tacos in or around Skokie?

I will want tacos tomorrow. Where should I go? I typically go to My Little Kitchen but open to new suggestions.

Any Chicago Bandits fans here with advice on going to games?

I'm considering taking my 6 year old to a Bandits game. I've never been so I figured I'd ask if anyone here had any advice like best spots to sit, random things to be aware of, and how entertaining it is for younger kids.
