Neat. Now for questions and comments. Often people have a requirements.live.txt, or other packages depending on the environment. Is that handled somehow? Can we use different files or sections? [ED: yes, different sections] Still wondering

Mining, shipping, and human transport driver jobs have all been lost to robots. There's giant trucks in WA Australia, the ports (again in Aus), and trains in airports. The big new train line in Sydney also has no drivers. (Not just the

This used to be true. Modern machine learning needs way less data. The classic example is taking images and then transforming them in hundreds of ways (scaling, rotation, skew, etc) for training. Big data is no where near as much a competit

An interesting aspect of these is that they are very quiet. Maybe they will allow flights past midnight, when the noisy planes are not allowed. With a range of 750-1500km, that puts most of Germany within range. However the speed (200km&#x2

Yeah, you're probably right... generation on board ship doesn't make much sense. Unless the ship is stopped for some time I guess. Storage for hydrogen can be really large, in the TWh size. Because they can use natural gas storage

For sure EV are a thing, and I don't think they are going away. But I don't think they'll be the only game in town. There are quite a few hydrogen cars driving around in Japan, and infrastructure there is almost rolled out. F

The current Toyota car being sold can go 312 miles per 'tank', and takes 5 minutes to refuel. Which is better than Tesla EV cars. It's much easier for trains, and larger vehicles to bring the infrastructure online. Existing n

For the German trains, luckily there is plenty of hydrogen that is a waste product of existing chemical industry in Germany. In many places there is extra power from wind, solar, and hydro which is wasted when production is too high. So the

Toyota seems to be the only ones able to do it in small vehicles well. Whereas it seems to be much easier in larger vehicles, since many more companies are bringing big vehicles to market. They use lithium batteries with the hydrogen chargi

Tesla is quite good at PR, and adding Tesla in a headline gets clicks. The article does say it's all the car companies, not just Tesla though. Also Hydrogen vehicles are a thing now. Trains coming online in Germany, and Toyota are sell

Some thoughts about recent developments which may change your mind about solar panels being useless in Finland ... Hydrogen production is now possible with renewable energy. There are some trains going into service in a few days in Germany
