Wouldn’t that be 60 Hz without a rectifier, and 120 Hz with one? If the voltage crosses zero twice per cycle, but goes negative only once.

What sort of horsey reasons? Now I’m curious.

The range and charging leave a lot to be desired for many applications, but the bikes themselves seem to be quite nice.

My concern is that finding chargers will be even more difficult than it already is since I don’t think there is any DC charging support. So none of the side-of-the-highway EV charging stations will work, and you’ll specifically have to seek out a level 2 charger next to a coffee shop or something. Just makes any travel longer than the ~130 km range even more hopeless.

If I didn’t already commute everywhere locally by bike, I would definitely consider something like this though.

Do we get to make the argument that if they’re not worn on their backs, then they’re not backpacks? Chest-packs maybe?

Definitely agree on the recycling. Carbon fibre is a whole can of worms there.

In general, agree with your explanation here, but would disagree on the repairability point. Lots of carbon repair shops will repair carbon parts. Often just needs paint sanded off and additional carbon bonded on. Generally doesn’t bend and deform like metal parts, so the cracked bit can just be cut out and reinforced.

On the other hand the aluminum alloys a lot of car parts and bikes are being made of end up quite difficult to weld and re-heat-treat in practice, so no easier than carbon.

Makes sense.

In that case better for efficiency than interior blinds, but still blocking your view out.

Would be handy for an especially hot day or week, but I wouldn’t like to have to keep my windows covered all summer.

Interior blinds are mentioned in the video: basically since they’re behind the glass the energy is still getting in and green-housing a bit. Blinds heating up is heat inside the room. Also block the view out, which awnings don’t.

In the PinkBike video, they mentioned that the full-face helmets didn’t perform as well in at least the rotational impact tests due to their higher mass and moment of angular momentum.

I think it always ends up being a bit of a trade-off, depending on the types of riding and impacts expected. In a low-speed impact to the side of the head a regular bicycle helmet will often do better than a big heavy motorcycle one. Obviously the opposite is true for a motorcycle crash at 80 km/h.

Run energy changes sound like a good idea. IIRC this is already similar to how RS3 does it; Iwonder when it changed there. Though weight feels like it has no impact in RS3, so that’s probably a good way to balance it.

I’m not sure I see this one to be honest. As bad as a car-dense city is for everything else, it’s probably the best option if the whole city had to be evacuated.

A large portion of alternate transport is focused within the city (trams, bikes, subways, etc). I suppose at least busses could be re-purposed for evacuation, but it requires a whole lot more organization.

Furor might be too, sibling.

Lol

I mean there will still need to be spring-loaded pins somewhere in order to make good connection. And tiny pins means someone will bend them by accident at some point. And the pins are still a little involved to make, so taking them off means the RAM can be made cheaper. So this means:

• if just replacing/upgrading RAM, then no need for extra pins to be made
• if adding ram to a slot that didn’t have any before, then can also buy pins or they can come in some kits or whatever
• when someone bends pins, then just the pins can be bought for a reasonable price, instead of replacing expensive RAM, or very expensive motherboard

That was one of the things that excited me most from the iFixit video; the (LGA?) pins are a separate part that can be replaced as well. Simplifies the motherboard because then there are just flat pads on there, which means they don’t need to include the whole array of fancy pins for a second module if it doesn’t ship with one.

Did they attach a PDF of an envelope?

I think this is the correct link for the SpaceX official feed on X/Twitter: https://twitter.com/i/broadcasts/1LyxBnOvzvOxN

Looks like it’s scheduled to start at 6:56 CDT now that launch is targeting 7:30 AM CDT.

Looks like some sort of fuelling is underway. Or at least chilling lines in the OLM and tower in preparation for filling.
