To hit 1 megawatt you either need even higher voltages, or higher current- both of which require stouter cables and connectors.

Higher current requires thicker conductors to limit resistive losses and heat buildup.

Higher voltage requires insulation to prevent sparks or leakage, but that's easy to handle and doesn't require a whole lot. The wiring in your house is usually rated to handle 600v, even though it will never see more than a 240v potential difference.

The quote in the press release is "the first civil supersonic jet made in America." Which is true.

Am I the only one who has no idea what a "URL Breadcrumb" is?

All I see in my Chrome browser's URL bar is a URL.

The one place where Level 1 charging makes a lot of sense is airport parking lots.

If I'm on a week-long vacation, then a 40-hour charging time is perfectly acceptable. And the lower cost would allow the airport to install a lot more stations. Level 2 charging at airports is just overkill.

The only thing Starship might do is bring down launch costs, but you're still talking about billions of dollars here.

For something like James Webb, probably. But that's because we're so used to the "we can only afford one so over-engineer it" approach.

Starship launches should be cheap. And it can put a lot of stuff in orbit. So take the starlink approach instead of the Webb approach. Every university and college - and even community college - will be able to afford to put a small telescope in orbit that will last a year or two before the orbit degrades and it burns up in the atmosphere. Don't try to overengineer these things. Make them cheap and just launch another every few years.

For something like James Webb, Starship is large enough that it wouldn't have had to bother with that fancy mirror-origami engineering. It could have been launched as a single mirror instead. That would have greatly simplified the engineering involved. Starship is so big that the entire mass of the International Space Station would have only taken two launches to create. It's really going to be game-changing.

Is it just me who finds it hard to concentrate when standing?

I started using a "walking workstation" at work (basically, a desk with a treadmill) for an hour a day, because they have them available here and it seemed like an easy way to get a little exercise. I found it very difficult to concentrate on anything at first. But as with many things, I got used to it and now it's pretty much just as easy for me to concentrate on stuff on the walking workstation as it is sitting at my desk.

Absolutely.

Starlink isn't meant to compete with existing broadband in well-served communities. It's competitive in under-served areas. People in urban and suburban areas shouldn't bother getting it.

"Compared to the faintest astrophysical sources that we observe with LOFAR, UEMR from Starlink satellites is 10 million times brighter.

The only Starlink satellites I've ever noticed in anybody's photographs are the recently-launched trains of satellites that are still maneuvering into their final orbits. SpaceX has done a good job of keeping the albedo down once they're in a stable orbit.

So, I wonder what more noise they're gonna add.

Next, they should launch telescopes.

Once Starship is able to launch commercial payloads, it will become very cheap to put all sorts of telescopes in orbit where you no longer have to worry about atmospheric distortion and various satellites photo bombing your nighttime sky shots.

There aren't NEARLY enough non-Tesla EVs in North America (except perhaps in California) for this to cause any additional congestion at supercharging stations.

GM may have a lot of EV models now, but none of them are being produced in quantity.

The fact is, we've pretty much reached the limits of space observation from the earth's surface. The earth's atmosphere distorts and dissipates most of what is viewed. What we need are more space-based telescopes. SpaceX is bringing the cost of launching things into space down. When Starship is operational, it will drop the cost of space travel by another two orders of magnitude. At that point, the cost of putting small telescopes into space will be within the reach of every college and several smaller institutions. Then we'll really begin to see some great discoveries being made.

And a lot of that development is going to be supported by starlink revenue.

Microsoft, like all modern software companies, became a data broker company. It is what Google is, what Facebook is, what Netflix is... Probably the only big company that isn't a data broker is Apple, and that's because they keep the data to themselves.

Google also keeps the data to themselves. They don't share or sell it. What they sell is ads. They'll show your ads to users for a price. They'll display ads on your website for a price. But they keep that data to themselves and use it to determine how to target all of these ads to users.

If you're a fan of TOS, and you haven't already discovered Star Trek Continues, you owe it to yourself to watch it. It's a continuation of the original Star Trek, with the same characters (different actors, obviously). The acting is on-par with the original series, and the filming style is exactly the same. James Doohan's son plays Scotty. The late Grant Imahara (of Mythbusters fame) plays Sulu. A few actors from TNG make appearances (as different characters). It's really well done. I especially liked how they bridged the TV series to the first movies in the final episode.

Star Trek Continues

Given each time someone comes back it uses up a launch module...

Starship doesn't get "used up". It is completely reusable.

That's exactly how SpaceX plans to bring spaceflight costs down by a couple orders of magnitude. They won't be throwing any part of the rocket away.

Also, I'm not saying "don't work on researching new technology until you've fully solved all of the problems at home". I'm saying " "don't work on researching new technology that isn't aimed directly at addressing the existential threat we're faced with". Yes, I'm aware that work on space travel has granted us numerous important 'spin-off' advances and benefits. But we can't afford to spend effort on space exploration in the hope that the benefits therefrom will somehow help us to either solve AGW or mitigate its effects.

And that reply just goes to show that you have ZERO understanding of the reply that Rei wrote to you.

There's a simple way to solve the existential threat that you believe exists - force everybody to become Amish. Give up air travel. Give up automobiles. Do you remember reading about the huge reductions in CO2 that resulted from travel and manufacturing shutdowns that were enforced during COVID? Oh yeah, give up computers, and phones. All communication has to be written into letters and books.

The fact that you're here on Slashdot just goes to show that YOU PERSONALLY are wasting time doing things that aren't aimed to directly combat that existential threat. Yet you think everybody ELSE should be doing so. Why is that?
