alex_h commented on A battery has replaced Hawaii's last coal plant   canarymedia.com/articles/... · Posted by u/toomuchtodo

Fun fact - the exhaust cooling tubes at that old plant dump out into the ocean and create a really warm environment that is rich in sea life and a very popular diving/snorkeling spot. It's even called Electric Beach. https://www.snorkeling-report.com/spot/snorkeling-electric-b...

I lived there for a few years and tried to snorkel there - but my submechanophobia prevented me from getting more than a few feet into the water. Seeing those big spooky tubes scared the ever living shit out of me.

The Kahe (oil powered) plant at electric beach is still operational. The coal fired power plant that shut down is a little further south of there, closer to Barbers point.

Yes, but water coming from the cold water tap has spent less time sitting in that accumulated stuff.

Seems like the presence of the accumulated gunk in the cylinder means the hot water must be cleaner by definition? The accumulation being the net difference between what was dissolved in the incoming water and what is dissolved in the outgoing water.

With the exception of gunk that is from the lining of the cylinder itself of course.

Well, there's a selection bias in LPL's videos: If he can't pick a lock today, he doesn't make a video until he can.

But you're right at a higher level: 99% of buildings have glass windows. Paying $$$$ for locks that go beyond "keeping honest people honest" is pointless if they can be bypassed with a rock.

alex_h · 4 years ago
LPL has discussed locks without being able to pick them, eg the Bowley lock

How would one go about trying to get this law enforced on a company? I live in California where this tactic has supposedly been illegal for 3 years already, but when I go to cancel my AT&T internet subscription, I still can not do it online and am forced to call.

wouldn't large scale usage of a device like this essentially increase the planetary albedo and help fight climate change? especially if you just skip the "environmental heat transfer" part

There's some numbers here for what it would take.

Basically we need 1W/m^2 of cooling for the earth, so if you could get a radiative cooling device with 100W/m^2 you'd need to cover about 1% of Earth's area

I think the sentence is meant to be read: "As many Jews as [the number of] Signal readers" i.e. equating the size of the groups, not saying that they were the same group.

Looks like we're currently hovering around 21.39% and were at 15.26% on 2021-01-31.

6% in ~22 days

At what level are we considered herd immune? When 50.1% of the population is immune/recovered?

alex_h · 5 years ago
It depends on the r value of the virus. A more transmissible virus requires a higher level of population immunity. Most common estimate I've seen for covid is 70-80%

Can it turn a well written email into a short list of facts? That seems more useful.

Interesting, are you able to share more? Or if you know where I might be able to read more about this?
alex_h · 5 years ago
I'm definitely not an expert on options contracts, but the examples of clauses I've seen are:

(In the options exercise agreement): "All certificates evidencing shares purchased under this agreement shall bear the following legend: "The shares represented hereby may not be sold, assigned, ..., except in compliance with the terms of a written agreement between the company and the registered holder...""

(On the share certificate): "This certificate and the shares represented hereby are issued and shall be held subject to all ... bylaws of the corporation, to all of which each holder ... agrees to be bound"

Either of which seems to give the company the ability to unilaterally reject any transfer/sale of shares.

How does something like this mesh with selling common stock but the company having right of first refusal?

Say I want to sell common stock that I own, to someone who meets the SEC accredited investor definition. It seems that right of first refusal means that the company could buy the stock instead, but it would have to be at the price that I set with the external investor. In that case, don't I as an employee get liquidity either way, since it's being bought at the agreed upon price?

alex_h · 5 years ago
I learned the hard way that options agreements tend to have additional clauses allowing the company to unilaterally restrict sales. The contract might look like it has a straightforward process for employees to sell, with a company first right of refusal (with the company purchasing the stock instead). But there is usually additional fine print that basically gives the board veto power over any transfer of stock.
