Diversity is important, but it's still better to go after larger sources of energy first. There's just not much energy to be recovered from falling rain or waste from cars.

Make the cars waste less energy, or the transit system in general is much easier and will actually save money long term.

The actual paper https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11100893/

It's still a preprint, and I didn't see the exact figure but definitely concerning.

Ehh it's still a rubbish idea, that money would be much better spent going after primary producers of energy, like solar, wind, geothermal, or nuclear.

Some napkin math and an equivalent area of solar, say over a road or parking lot would produce 3.5 million kwh in a year.

Honestly I'd wonder if the wear on brake pads could be cheaper than the additional strain on the battery.

Honestly given how Frank Herbert wrote other female characters in the books, I interpreted chani as a satirization of settler/colonizer wife.

It's rather subtle, and would not likely come across well with a movie audience.

I'm a bit surprised at a lot of the criticisms for the movies here, and I say this as a huge fan of the Dune novels too.

Villeneuve has a particular film style like blade runner 2049, and Arrival.

If you don't like his style you won't like the 2nd movie.

But on the other hand part 1 sets the stage for everything that happens in part 2, and overall I think it is an excellent adaption. Dune is not an easy book to adapt to film, and some changes had to be made, but they're aren't any glaring changes that make me go "why the hell did you change it that way?"

It's extremely faithful to the book, and in cases where it's not, I can see the reasoning for the change.

You can't slow down with regen without putting the energy somewhere, and that's the point of brakes, they convert kinetic energy into thermal to slow you down.

The point of regen is to not waste the energy and put most of it back into a battery. At the scale of an ebikes, the additional components electronics, battery thermal management, and so on for regen are more expensive than just adding 20% more battery.

Unless you wanted to make an expensive, super efficient or very light ebike, it just doesn't make sense at the moment.

That will not likely always be true if we ever use different battery chemistry and the cost of regen electronics goes down.

It's not a common feature.

It doesn't make as much sense to do on an bike, mainly because regenerative breaking requires more expensive electronics and stresses the battery more.

My family has 7 ebikes, all different models and none has regen.

I am confused, the gear s3 came out in 2016, so even 2 years ago it was already 6 years old.

That is not what I would consider new smartwatches these days.

I imagine they have value because they can be used to buy things from the federation itself.

It's the same for any currency. Voyager had to barter for goods since credits don't mean anything in the delta quadrant, but that is less convenient for both parties than a standard currency.

Even if it's not bullshit, from what little I understand it's essentially unprovable. Which makes it useless in science.

I mean the books are great too, apparently they're even better in it's native language.
