Well, trials are there for a reason. Battery-only-powered trains could be a good idea or a bad idea.

Remember the trial project for overhead wiring for trucks on the motorway? It ran for a couple of years, and the end result was that it wasn’t feasible, despite some interesting benefits. But if it weren’t for the trial, some people would still think it was feasible, while others would think it was unfeasible.

I’m leaning more on the unfeasible side with this train, but let’s just see what happens.

Thanks, glimpsed over that line too fast. So durability concerns are most likely the limiting factor, hence the trial run. If, say, the battery can’t keep up wih continuously getting topped up and fails after a short time, it’s impractical/expensive. But could be the other way around as well.

Makes me wonder if this is cheaper than refitting a train line with overhead wiring and if not possible, power rails.

On e cigarettes specifically, after having watched bigclive dismantle lots of them, showing that they are practically just a few tiny cheap components away from being rechargeable and refillable (and they can indeed almost all be recharged and refilled), I guess manufacturers simply saw a market for it. It’s stupid from start to finish, but then again cigarettes as a whole are stupid.

Actually, some of them aren’t remotely placed correctly.

I wish I could do that. Unfortunately my rented flat requires 23°C of heating to prevent mold thanks to bad windows that cannot be fixed due to the house community not wanting to pay for replacing them. And yes I’m practicing proper venting, supported with several devices for timing. I’m so glad I’ll be moving out soon.

Many reasons actually. You more than likely have something on you and use something daily that only exists due to things implemented for space travel. Those “side products” really add up, since space is so frigging hard on everything, which forces human innovation to go beyond the current limits. That new ground is what fuels innovation, fuels economies, fuels wealth. And that in turn should power things like space travel, since that helps growing the space for innovation even further.

While I could point out obvious stuff like PV-panels or smartphones, how about thermoacoustic refrigeration? Invented for the James-Webb Telescope, they are currently evaluating entire new fields where this cooling method saves lots of power - remarkably, the Telescope was planned with this technology even though it did only exist as an idea at the time, not even as a working prototype. That created lots of jobs and now keeps creating new ones as it opens the field for cooling things to near-absolute zero that are highly sensitive to vibrations. They are still trying to understand the technology, since it works.
