Software Engineer and general technologist. 20+ years experience (majority at Google, working in Corporate Engineering, Energy/Climate, Maps, Search, ChromeOS, and others).

Now working primarily in climate tech and adjacent spaces.

Interests:

- Energy/Climate Tech (especially decarbonizing and bringing resiliency to the built environment, electricity, transportation).

- Applications of emerging tech to solve problems in climate and energy, education, and quality of life for the majority of people.

- Linguistics (especially historical, also computational and social).

The best way to get in touch is to triangulate me on the Internet (shouldn't be hard from my comment history) and reach out over LinkedIn.

I noticed the same in India not long ago. Unlike in the US, there is broad cultural aspiration toward electric vehicles.

Even tuk-tuk/rickshaw drivers (who are largely lower income) have EV choices, while in the US lower income workers - like rideshare drivers - don't have many cheaper electric options, since EVs are mostly priced for upper income people.

It doesn't hurt that India has to import the vast majority of the petroleum it uses, and has unlimited solar resources.

> most customers buying from different US entities

I understood "customers" here to mean companies training AI models, buying human labor to assist with that.

It's interesting that in Europe the customer and the labor appear to be relatively colocated. Any theories as to why?

> AI may be a great calculator, but in business, intelligence is mostly judgment. Judgment depends on context, and the answer varies with which human or which model you ask. Perhaps most importantly, AI does not understand accountability, trust, culture, unwritten rules, ethical trade-offs or fairness, all of which shape reputational risk and ultimately drive revenue growth and profit margins.

All of this is true, but the reality is that LLM agents free up time for people to make judgement by taking care of the grunt work, which means each person can do more. That increased efficiency can mean higher revenues in growth industries and higher profits (through reduced labor force) in stable or declining industries.

> - trading (who knows best when to buy how much?)

That seems odd. Does a local water futures market exist.

> - consumer-facing marketing

If it's all going through the same pipes, what is there to market.

Electricity is a different story - it can be traded day ahead and even marketed, but none of that makes sense for water delivered over shared infrastructure.

> In that counter-factual do you propose that she/her company actually/eventually develops what they said they did? So a fake-it-until-you-make-it gone right?

No, I mean the fraud continuing, and how much of a culture of knowingly cheerleading and gaslighting fraud exists in a forum such as this. Is it the majority, or is it a loud minority.

From Theranos to meme coins and NFTs, there is a long history of shilling for outright fraud here.

The documentary aside, if she hadn't been caught for the fraud, I wonder how many of us (myself included) would be singing her praises. I wonder how many people are operating like she did right now.

What a wonderful illustration of the technofeudalism that many seem eager to push our world into. That doesn't diminish the engineering feat it embodies, in fact it rhymes pretty well.

In parts of South Asia crows are considered messengers to dead ancestors and are hence fed as part of memorial rituals. This role is probably in no small part due to observations of their intelligence.

It's not so much being unplugged as it is sensing whether the mains power is down. If it is, they stop backfeeding immediately, just like hardwired solar inverters do.

If this weren't done, there would be risk of electricution to anyone working on wiring in the house or on the utility distribution network.

Yes, but last I checked the bidi chargers were proprietary - tied to vehicle manufacturer - which is a huge disincentive. I don't want my home's battery connector locked into a vehicle brand/manufacturer.

> Tesla Electric customers report making as much as $150 a day

Only on peak demand days, of which there are only a handful every year.

I have Enphase batteries enrolled in an equivalent program, so I've tracked how much I make. Definitely not enough to make much of a dent in the payoff time for the batteries. But a nice perk nonetheless.

> I still don't get the point of Chromebooks. You need the exact same hardware as a real laptop, you don't get to save on anything, in fact it's worse, since browsers are usually heavier than real apps.

If by "Save on anything" you mean saving files, you are completely wrong.

There is a filesystem that you can save any data to. If you use the Linux VM you can run nearly any typical Linux software (including any of the in vogue coding agents). You can even run llama.cpp or ollama with GPU acceleration, though you might be constrained by the laptop level GPU and Memory constraints.

There are completely offline apps and tools available (via Android, Linux, and even offline PWAs).

You can even write your own apps and run them only locally on the any of the above 3 runtimes.

Of course, I wouldn't do these on a school-specced Chromebook that costs $200, but $700 Chromebook would easily suffice.

If you mean "Save money", then that's wrong too. ChromeOS is by default more lightweight than traditional Desktop OS's because of the relative lack of legacy cruft and the managed runtime. Even the Linux distro it includes is very stripped down by default (although you can bog it down by running too much stuff like any computer)

The only thing you can't do is run Windows or Mac specific software, but if you need that, ChromeOS was never a consideration anyways.
