This is pretty big news for an AI and Robotics company to move from Austin to Detroit. Granted the owner grew up in the D. This house is pretty amazing but kind of run down. But he is planning on investing $5 million to restore it.

Former Detroit Pistons star, John Salley, of the 'bad boys' era first bought this place from the church. He wanted to do movies after he was done playing basketball. He would invite movie stars, script writers and directors to live in the various bedrooms and that is how he built his network which is pretty shrewd.


The story talks about Dearborn which is adjacent to Detroit but not part of the city. However as Detroit underwent its well publicized bankruptcy fifteen years ago one of the benefits was turning back on the city's streetlights. The entire system was updated at that time and one of the benefits cited was they were spending the extra money so that they could easily add EV charging. To my knowledge it was never implemented, even on a trial basis.

Instead the governor spent millions repaving a short stretch of road that could recharge EV's. But most EV's couldn't make use of it and its such a short stretch of road you couldn't easily get any meaningful recharge.

I am a little sad that there can't be agreement that this type of reform can't be bipartisan.


As I have mentioned on here often I spent twenty years as a fertilizer company agronomist before transitioning to tech. So I know all about NH3 or anhydrous ammonia. If these guys are really able to cut both the price and the pollution generated from manufacture by 40% this is a really big deal.

Where I disagree is using anhydrous ammonia as a power source. I was safety officer at the last fertilizer plant where I worked. We had to identify every home owner within a certain distance according to state law. I knew every house, their phone number as well as the total number of the people at the residence. If we had a leak on ammonia (which is a gas) everyone needed to be contacted to evacuate. If we were unable to reach them we needed to physically go to their house and knock on the door.

Luckily ammonia leaks are fairly rare, the company I worked for had five locations and in their fifty year history had never had it happen. But the stuff is really that dangerous.

The previous company I worked for did have a leak before I worked there. The delivery driver didn't know what he was doing and overfilled the tank. The owner put on a suit with an oxygen tank, shut everything off and then started filling empty portable tanks (that the farmers used for application) until the big tank was below 85%.

So I cannot imagine a train or semi-truck running on the stuff since they do have real accidents each year.

Seems still missing some content but at least it lists the car makers (Hyundai showcased something, Mercedes commented)

This is genius, here in Michigan the city's along Lake Michigan get 'lake effect' snow that is a multiple of what occurs in the rest of the state. Muskegon tackled it with tunnels although most of them are closed now.

Could a data center that was water cooled end up melting snow off streets and sidewalks? It would be an easier sell to the public imho if it did.


Roadway heating to reduce snow melt costs sounds like a good use for waste process heat, for example from datacenters.

FWIU typically it's necessary to amp up waste heat in order to get it to move through a heat pipe under a street.

There are LEED Green buildings that are heated by datacenter waste heat.

From https://news.ycombinator.com/item?id=42694570 :

> Most datacenters have no way to return their boiled, sterilized, [demineralized] water for water treatment, and so they don't give or sell datacenter waste water back, it takes heat with it when it is evaporated.

> "Ask HN: How to reuse waste heat and water from AI datacenters?" (2024) https://news.ycombinator.com/item?id=40820952

A sustainable thermofluid would increase the efficiency and sustainability of heat recovery and reuse operations


It would be great during the cold months, but Michigan does have four seasons and summers do get hot.

You could potentially pump the heat into the ground to use as a seasonal energy store, or otherwise switch to air cooling when you're not in district heating mode. Perhaps sell the heat energy as ConEd sells steam service in NYC [1] (serving 3M people).

Given the age on here it is doubtful you will see the virtue in what these guys are doing. But as someone older who has had friends fall and break hips, it's one of the worst things that can happen to a person. I cannot prove it but am absolutely certain that breaking a hip will shorten your life.

I think they need to lose the LED's and bring the price way down but I am watching this one.


I thought it was still up in the air whether the majority of the time geriatric people fell and then broke their hip. Or their hip breaks first, causing them to fall.


Although I absolutely love the line - Goodbye Torque. Hello TeraFLOPS! Somehow I don't think TeraFlops will ever be much of a reason why people chose one car over another. But I can believe AI and self driving might be. Got a friend who writes a full blog post every single time Tesla updates his beta version of FSD. So for some that can be the defining factor.
