A real-life use today when some-one asked me for advice about buying a mechanical watch as a gift, an area I know nothing about:


Me: when buying a mechanical watch, what should one look for

CHatGPT: When buying a mechanical watch, there are several key factors to consider:

Movement: Look for watches with a high-quality mechanical movement, such as those made by Swiss manufacturers like ETA, Patek Philippe, and Rolex.

Build quality: Look for watches that are well-constructed, with attention to detail and finishing.

Brand reputation: Consider the reputation of the brand, and research customer reviews and ratings before making a purchase.

Functionality: Consider the features and functions that are important to you, such as a chronograph or a power reserve indicator.

Design: Mechanical watches come in a wide range of styles and designs, so consider what you like and what will suit your personal style.

Serviceability : Consider if the brand or model you're looking at is easy to service and if the parts are readily available.

Price: Mechanical watches can range in price from a few hundred to several hundred thousand dollars, so determine your budget and stick to it.


Me: which brand of watch is recommended for between £250 and £300

CHatGPT: There are several watch brands that offer high-quality mechanical watches at a price point between £250 and £300. Some popular options include:

Seiko: Seiko is a well-known Japanese brand that offers a wide range of mechanical watches at affordable prices. The Seiko 5 is a popular collection that offers a variety of styles and features at a very competitive price.

Tissot: Tissot is a Swiss brand that offers a range of mechanical watches at a variety of price points. The Tissot Visodate is a popular collection that offers a classic look at a reasonable price.

Hamilton: Hamilton is a Swiss brand that is known for its high-quality mechanical watches at an affordable price point. The Hamilton Khaki Field is a popular collection that offers a classic look and robust construction at a reasonable price.

Oris: Oris is a Swiss brand that offers a range of mechanical watches at a variety of price points. The Oris Divers Sixty-Five is a popular collection that offers a classic look and robust construction at a reasonable price.

Bulova: Bulova is a well-known American brand that offers a wide range of mechanical watches at affordable prices. The Bulova Moon-Watch is a popular collection that offers a variety of styles and features at a very competitive price.

These are just a few examples, and there are many other brands and models to consider within that price range. It's always a good idea to read reviews, check ratings, and compare features before making a purchase.


Me: which one do you recommend for someone who does electrical engineering

CHatGPT: For someone in the field of electrical engineering, I would recommend the Seiko SKX009. This watch is a part of the Seiko's dive watch collection and known for its rugged construction, reliability and precision. It has a mechanical self-winding movement, a water resistance of 200 meters, and a unidirectional bezel, which makes it ideal for someone who works with electrical equipment and may need to measure time underwater or in other demanding environments. Additionally, the Seiko SKX009 is known for its affordable price point and it's easy to service and maintain.

Furthermore, for an electrical engineer, a watch with a chronograph function could be useful as it allows for precise timing measurements. Watches with chronograph function can be found in the same price range as the Seiko SKX009, and with a bit more budget some options like Tissot T-Race, Hamilton Khaki Field Auto Chrono, and Oris Divers Sixty-Five Chronograph are also available.

It's important to keep in mind that watches are also a personal preference, and you might have a different preference in terms of style, size and features. It's best to try on different watches and see which one feels the most comfortable and suits your needs the best.

Wow, that is amazing. Not quite the same idea, but a quick answer for people who ask where is all the electricity for the EV revolution will come from.

I like that the solar panel is pretty large - the idea is serious and not just for show. https://www.youtube.com/watch?v=a0WujevWAhM

Even better would be to charge at work from cheap solar and then return it during the duck curve.

I just had an interesting business idea - make a parking garage for cars with V2G capability (probably best at a Park and Ride facility) covered with a solar roof, charge the cars in the day and deliver the energy in the evening using a virtual battery. People get cheap parking, you get a cheap battery and the grid gets cheap energy. Win,win,win.

This bit is unnecessary and wrong. Cars will be replaced automatically over the next 20 years in any case - there is no need to extend the life of ICE engines.

eFuels will continue to be necessary for airlines and cargo ships, so there is a good enough reason for them to exist.

The important line for the doomsters:

> “Electricity is the largest demand sector for fossil fuels,” said Bond. “The peak here marks a key turning point in the energy transition and gives us hope that we can hit the goals of the Paris Agreement.”

You should take your hope^2 since its exponential growth and renewables have always grown faster than predicted.

I'm just going to post this for you again, since you obviously did not read it:

BTW, in your estimation, what percentage of cars on the road in Norway are electric?


We know EV sales have hit 90% market share in Norway, but there has always been a question of whether they are an outlier and if the rest of the world will follow. Multiple European countries are now showing that Norway was just the forerunner and are rapidly following in their footsteps.

In December 2022, new passenger car registrations in Germany increased by 38% YoY to 314,318, the highest monthly result in 42 months. The most significant result was the massive surge of plug-in electric car sales, both all-electric and plug-in hybrid. In December, 174,126 new passenger plug-in electric cars were registered in Germany, 114% more than a year ago, and a new all-time record. The market share of rechargeable passenger cars in December amounted to 55.4%, a new record, far beyond the previous one of 39.4%, and a true sign of the times that plug-ins are now in the majority.

The reason behind the surge is largely related to the reduction of incentives for BEVs and elimination of incentives for PHEVs from January 1, 2023, meaning January numbers will likely be a lot lower, but there is little doubt that ICE cars are now legacy cars increasingly relegated to the second-hand market.

Notably, the UK also saw record numbers of new electric car registrations in December 2022, with 42,284 all-electric cars (BEVs) and 8,367 plug-in hybrids (PHEVs) registered. This led to a market share of 32.9% and 6.5% respectively or 39.4% combined. The total number of new plug-in electric car registrations in December was 50,651, an increase of 41% YoY. For the year 2022, more than 368,000 new passenger plug-in cars were registered, reaching an average market share of 22.8%. This is a new record and notably better than 2021 (305,281 and 18.5% share).

Given the 14-20 year replacement cycle of passenger cars, it appears likely by 2050 there will be no ICE cars on the roads at all, which should go a long way to meeting CO2 emission targets.

> Norway is an outlier.

And Germany just had a 55% plugin market share and UK 39%. An outlier no longer I guess.

> Also what is the worlds lithium supply (maybe 130million tonnes?)

That was 10 years ago. Currently, it's 220 million tonnes. Are you surprised it actually increased, not decreased?

> As you use it and other metals class 1 nickel, copper, chromium as demand grows so will the price

And then you skip to alternatives, such as aluminium instead of copper, and LFP batteries instead of NMC.

> Also the Japanese are working

Japan is about to go bankrupt because they won't admit the EV revolution is happening.

Because wind and solar tend to be seasonally complementary.

I like the idea to turn it into jet fuel - the most difficult area to electrify. Maybe also fuel for cargo ships.

There is no need to guess - check the US government's report:

https://www.usgs.gov/centers/national-minerals-information-center/lithium-statistics-and-information

>Four mineral operations in Australia, two brine operations each in Argentina and Chile, and two brine and one mineral operation in China accounted for the majority of world lithium production. Additionally, smaller operations in Brazil, China, Portugal, the United States, and Zimbabwe also contributed to world lithium production. Owing to the resurgence in demand and increased prices of lithium in 2021, established lithium operations worldwide resumed capacity expansion plans which were postponed in 2020 in response to the global COVID-19 pandemic.

> Lithium supply security has become a top priority for technology companies in Asia, Europe, and the United States. Strategic alliances and joint ventures among technology companies and exploration companies continued to be established to ensure a reliable, diversified supply of lithium for battery suppliers and vehicle manufacturers.

> Brinebased lithium sources were in various stages of development in Argentina, Bolivia, Chile, China, and the United States; mineral-based lithium sources were in various stages of development in Australia, Austria, Brazil, Canada, China, Congo (Kinshasa), Czechia, Finland, Germany, Mali, Namibia, Peru, Portugal, Serbia, Spain, the United States, and Zimbabwe; lithium-clay sources were in various stages of development in Mexico and the United States; and a searlesite source was in development in the United States.

Stop being such a sceptic - it does not make you sound smarter.

Leave it to the people whose job it is to solve these problems.
