> They failed because of the basic economics of EV rentals: maintenance costs and depreciation That sounds like a Tesla problem, not an EV problem. There's no particular need for body work on an EV to be particularly expensive, and

Travelers are in a particularly poor position for charging. You're on a schedule, you don't have the accounts, you don't know where things are, you don't know how the car works, etc. But your latter group is a fine match

The world worked fine before 1908-1967 when DST was introduced.

That requires imaginative ideas for paying for such missions.

Pis are expensive? A Pi 4 and all accessories is about $100. Where am I going to do better? Every time someone says this I go look at NUCs and other minis and I don't see anything cheaper.

Well, it's a service for banks that will allow them to offer their customers realtime transfers between banks. Just like ACH. I don't use ACH directly, but I do use it through my bank all the time.

Thrust to weight of a nuclear engine is fairly poor, so they are best suited for upper stage or in-space work. A heavy-planet rocket might use chemical propulsion in a lower stage just like we do and a high-energy nuclear upper stage (or tw

Alfred was styled "King of the Anglo-Saxons"; his grandson and (indirect) successor Æthelstan was first styled "King of the English". The same kingdom was taken by William I, who also styled himself "King of the Eng

I suspect Apollo spent a great deal more money in quality assurance than this $120 million-ish project.

Yep. Basic rigging procedures would have prevented this several ways.

If you know GPS is unreliable in specific areas, it's not hard to get around with rough accuracy. There's still a compass, after all.

Almost any filter will handle cat hair. You probably want to find something with a washable pre-filter (usually a stretch fabric) so you don't waste the expensive actual filter. If that's your only concern, a t-shirt over a box fa

This article is looking at "apps" on the consumer side. While not an excuse for being as terrible as it is, consumer shipping is not where the money or focus is in package delivery.

Tolkien would have had at least a pretty good instinct for the feel of the post-Roman world as he was heavily exposed to primary sources... and lived in the turn-of-the-century English countryside, which would have still felt recognizably p

Seems that the Earth's shadow is 1.4 million km, and the Hill radius around 1.5 million. That ratio won't be the same for different size planets, as they scale differently with mass, but I doubt you'll get eclipses in any pla

Yes. Deliberately. While not explicitly against the guidelines, jokes are generally considered to not contribute to the conversation.

At certain phases. It will not have enough thrust to survive that at low speed/altitude.

AFTS activation indicates deviation from planned trajectory. It's unusual, being so late in the burn. Could be a guidance issue, but SpaceX should be pretty good at that by now. Could be engine underperformance, but we got nominal call

I would be shocked if it were measurable. The launch is 5 miles away and the breeze blows inland.

You won't be able to park at the park anytime near the launch; it will be full. But you can just walk down the beach to the jetty from anywhere else on the island.

A bomb truck is a cost-effective way to get cruise missiles and such in range from safer out-of-theater air bases. Making it survivable in a contested environment (stealth) opens up lots more mission profiles and lets you use even cheaper m

Looting was in large part the payment for soldiering. Whomever raised the army might pay a bit regularly for maintenance, but all the real money was in the spoils, and everyone involved knew it. Many is the army that failed to destroy a def

Notable that the Edison houses aren't form-cast like we do today, which is just structural and rather rough; the concrete was meant to be the finished wall both interior and exterior, including the roof and all interior and exterior or

US energy mix is 60% fossil, 18% nuclear, and 1% biomass, which are all basically steam turbine. The remaining 20% is "renewables", about half wind. World mix is similar. Is 80% "nearly all"? Dunno, that's semantic.

One of the benefits of Hollywood is rental and studio stock. Many of these sets are one-off or occasional, and the furniture would return after the shoot.

An explicit renewal regime with some reasonable fee would allow most works to pass into the public domain, and avoid objections from owners of still-valuable properties. (I like the concept of renewal fees escalating each period, a kind of
