As an owner of the complete History of Middle Earth series, these books are not for the casual fan, or probably even the average fan. They really are more designed for Tolkien scholars, and anyone picking up The Nature of Middle Earth expecting ripping yarns filled with Hobbits and wizards is going to be very disappointed.

Disruptively protesting in the workplace is pretty much exactly what their cause demands in this scenario.

Sure, and they should expect that they're putting their jobs on the line for their cause. Without that risk, their protest isn't particularly meaningful. If they were to "win" by getting Google to cancel the contract, they'd actually have little effect because Google is almost certainly right that this contract has little to no effect on the war.

Generating headlines by getting fired from their $500k/year jobs is the most effective thing these Google employees can do for their cause. So, good for them, they succeeded!

If they expect Google's decision to generate significant public or internal backlash, though, I think they'll be disappointed.

Comment costs of generation vs distribution (Score 2) 268

From what I've seen mentioned on this they are getting high electric bills not because of high generation costs but because of high distribution costs.
So someone is out blaming solar when it's hardly the problem and if it really were the problem the solution is spreading out 7-14kWh batteries on homes with solar.
But instead, we see massive mega battery stations getting funded by State and Federal agencies and being put out in the boonies so expensive distribution lines need to be installed or upgraded. A win for the utilities and even more costs to the consumers.

Home storage using LFP batteries are the way to go for flattening the solar output curve and eliminating the 4-9p high energy usage bump.

Too costly and they tend to catch fire, also needs a big footprint for very little energy. You're much better off storing water but that is something California already has trouble with so unlikely to be viable. There is a reason battery banks in eg. datacenter only provide 15s of power, despite having the same footprint as the generator.

Titan's atmosphere is rather calm; not an issue. At the surface, the winds measured by Huygens were 0,3 m/s.

You actually can use solar power in extreme environments - even Venus's surface has been shown to be compatible with certain types solar, though you certainly get very poor power density. Dragonfly, as noted above, uses an RTG.

Yes, they show you non-EV tires, but as you said, the load rating is different because the vehicle is different, the rubber is harder etc etc. look up the difference before stating something you know nothing about.

240V @ 80A for a single circuit is the problem - 100A is the house breaker in many rural places. 200A is an average home and you haven't electrified everything. I have a fully electrified double home with now 400A worth of service and I don't have enough, especially not in winter when the heat pump doesn't work.

The Model 3 is a small sedan for $50k, I am driving an SUV or family sedan for half that price. A lot of people's electric panels are not in the garage, mine is literally on the other side of the house. Most people electrical panel's are central to their home, whereas garages are on the edges or more often around here, detached. Garages attached to home are more expensive for builders (there are extra code requirements) and electrical panels are centrally located for the exact same reason, cost.

Comment Re:Second flying drone to explore another planet (Score 3) 43

Planetary scientists frequently refer to moons that are large enough to be in hydrostatic equilibrium as planets in the literature. Examples, just from a quick search:

"Locally enhanced precipitation organized by planetary-scale waves on Titan"

"3.3. Relevance to Other Planets" (section on Titan)

"Superrotation in Planetary Atmospheres" (article covers Titan alongside three other planets)

"All planets with substantial atmospheres (e.g., Earth, Venus, Mars, and Titan) have ionospheres which expand above the exobase"

"Clouds on Titan result from the condensation of methane and ethane and, as on other planets, are primarily structured by circulation of the atmosphere"

"... of the planet. However, rather than being scarred by volcanic features, Titan's surface is largely shaped..."

"Spectrophotometry of the Jovian Planets and Titan at 300- to 1000-nm Wavelength: The Methane Spectrum" (okay, it's mainly referring to the Jovian satellites as planets, but same point)

"Superrotation indices for Solar System and extrasolar atmospheres" - contains a table whose first column is "Planet", and has Titan in the list, alongside other planets

Etc. This is not to be confused with the phrase "minor planet", which is used for asteroids, etc. In general there's a big distinction in how commonly you see the large moons in hydrostatic equilibrium referred to as "planets" and with "planetary" adjectives, vs. smaller bodies not in hydrostatic equilibrium.

Why?

NASA's obsession with Mars is weird, and it consumes the lion's share of their planetary exploration budget. We know vastly more about Mars than we know of everywhere else except Earth.

This news here is bittersweet for me. I *love* Titan - it and Venus are my two favourite worlds for further exploration, and dragonfly is a superb way to explore Titan. But there's some sadness in the fact that they're launching it to an equatorial site, so we don't get to see the fascinating hydrocarbon seas and the terrain sculpted by them near the poles. I REALLY wish they were going to the north pole instead :( In theory they could eventually get there, but the craft would have to survive far beyond design limits and get a lot of mission extensions. At a max pace of travel it might cover 600 meters or so per Earth day on average. So we're talking like 12 years to get to the first small hydrocarbon lakes and ~18 years to get to Ligeia Mare or Punga Mare (a bit further to Kraken Mare), *assuming* no detours, vs. a 2 1/2 year mission design. And that ignores the fact that they'll be going slower in the start - the nominal mission is only supposed to cover 175km, just a few percent of the way, under 200 metres per day. Sigh... Maybe it'll be possible to squeeze more range out of it once they're comfortable with its performance and reliability, but... it's a LONG way to the poles.

At least if it lasts for that long it'll have done a full transition between wet and dry cycles, which should last ~15 years. So maybe surface liquids will be common at certain points, rare in others.

Comment H19 (Score 1) 77

The machine I had was a HeathKit H19. This had it's own OS called HDOS. Not sure what the quality of that was or how it compared to CP/M. However the hardware also had ROM mapped to the first 2K or so (to run the program controlling the front panel display) which made it incompatible with CP/M. I somewhat remember it was already clear that all the good software was only for CP/M and I had the wrong machine and HeathKit screwed up. Anybody else remember these, have any comments on them? It does sound like creating HDOS was not a trivial amout of work, was anything interesting lost with it?

It's not morons.

It's people overwhelmed with multiple crisis scenarios that they can't handle. Most of us wish for a stable society and environment because it makes it easier to plan a future. You wouldn't build a house if you're not sure it's still going to be there in five years.

Calling people morons instead of understanding the actual problem is also a way to avoid looking at it too closely, probably because the complexity is overwhelming to you, too. Easier to just call people morons and be done with it.

Climate change is very much a social, cultural and political problem and the scientists have only looked at the meteorological and biological side of it.

Europeans are suffering with unprecedented heat during the day and are stressed by uncomfortable warmth at night.

Maybe some are, but both in my place and where my parents live (1200 km away, that's 750 miles for the metrically challenged) temperatures have plummeted to near freezing at night and single-digits during the day (in Celsius, that's the 35 to 45 range in Fahrenheit for the temperature scale challenged).

I don't doubt climate change at all. But shoddy journalism that creates headlines where those allegedly affected go "what? not at all, why are you lying?" only helps the deniers.

If you look at a weather map of Europe, like this one stuck in the early 2000s - https://www.weatheronline.co.u... - you'll see that at least right now only the very, very southern tips of Europe (in Spain and Greece, that's in the bottom-left corner and the bottom-right corner, no not the very corner that's already Africa, damn where were you in geography?) has temperatures above 20ÂC predicted for today, and that's not unusually hot for those regions.

We did have unusually hot weather 2-3 weeks ago, but they were unusual only for the season and still well below ordinary summer days.

Please get your reporting right, or you're only feeding the trolls that claim climate change is made up.

Depends on the records you take, there are older records, they are intermittent but demonstrate much higher temperatures in the past as well, the problem is that none of the equipment was calibrated to modern standards nor are the records continuous so it masks the peaks and valleys into an average with large error margins.
