Because the current van and truck experience for me is a tracking update at 6am saying "Your package is out for delivery" and then it actually gets delivered sometime in the next 12 hours. As a customer that's a crappy experience. Hopefully flex will push everyone to up their game with regards to delivery experience. If vans and trucks are more efficient then they should win out in the long run because they can opera…

I don't understand your comment. Do you mean that we should back to the 4-6 weeks delivery or if you're just annotating the notion that things have improved in the the last few decades?

There is a datacenter in AZ that takes advantage of low cost night power. They have giant underground tanks full of a proprietary solution that they cool down at night, and then during the day the use it to keep the DC cool. My guess is it's just antifreeze and water, mineral oil, or something similarly boring. It turns out this is pretty cost effective.

It should be almost trivial for a refrigeration mechanic to build a home scale system like what you have described to take advantage of free / cheap night time electricity. It's just a heat pump with the cooling side heat exchanger immersed in glycol & water,storwge tank and a pump. Maybe some insulation. Add a heat a set of heat exchanges fir a secondary loop in to the house.

I know absolutely nothing of cooling and refrigeration, but it is an area I've been thinking of transitioning my career towards (burned out SysAdmin) and learning as a trade.

What you just described is something I actually overheard a couple of guys talking about at a neighborhood pub. A/C and Energy efficiency are bit topics in Central Texas as other posts mentioned.

Do you have any articles you'd recommend for someone with a passive interest in renewables that may cover residential projects like this?

What about the controller? Also, why not use ammonia? I can imagine that condos could also use this in places like SF.

Amazon Citizenship: 1) They setup an offshore corporation for you in a low tax jurisdiction and give you payment processors to take checks and credit cards over the internet. Every few years, they move all of these corps en masse to lower tax jurisdictions, if any. More efficient competition among tax regimes. Amazon will file all pertinent taxes and paperwork and connects to your quickbooks to make that even easier.…

You print your passport yourself, because Bezos is proud of the cheap culture he creates.

I'd swap cheap with efficient.

One of my previous jobs was infrastructure maintenance in a data centre, I've worked closely with refrigeration mechanics quite a bit.

I'm at work at the moment, let me get back to you when I'm home.

Is there any energy market in the US where you can offer/buy "positive/negative operating reserve"? Probably more related to AWS: I could imagine Amazon getting in the energy market and trading negative operating reserve. The scenario would be: - offer cheaper AWS compute instances on the AWS spot market - sell the excess energy consumption as negative operating reserve on the energy market

What is negative operating reserve?

It still does - I'm in Australia.

The press release itself reads "Amazon will purchase about 90% of the power generated by the wind farm." so I assume the primary purpose is their data centers.

Interesting because there is no Amazon DC anywhere near that area.

Yet. I wonder if there are plans to open an AWS DC in Texas.

Industrial refrigeration components are very modular, controllers capable of handling this sort of set up are available off the shelf.

The whol set up is pretty much identical to a chilled water data centre cooling set up but with a smaller chiller and a larger chilled water reservoir.

Ammonia would probably be better, I was just thinking on terms of something a fregierstion mechanic could hack together as a proof of concept in a couple of weekends.
