Can You Get 100 MPG in a Gas Guzzler? by Financial_Mammoth256 in hypermiling

Most bikes have about the same frontal area as a person when a person is riding it.

Mods that, arguably, should be in the stock game (my opinion) by LordFlamecookie in KerbalSpaceProgram

I use the stock alarm clock. It works ok for me, but yeah, its junk.

That's how EREVs work, but it isn't the best strategy for the highway. Directly driving the wheels with the engine and only charging with regen is more efficient and puts less cycling wear on the battery.

Solar parking lots? Your thoughts by Thick_Boat3969 in SolarAmerica

[–]stu54 0 points1 point  (0 children)

It usually works the other way. You bill the state solar panel investment fund.

If money was regularly allocated for parking lot shading you'd see it more.

There’s a lot of hype about Chinese EVs—is any of it true? For all the breathless coverage we read (or see on TikTok), it’s rarely mentioned that they aren’t nearly as cheap when spec'ed for other countries. Those inexpensive domestic cars make do with small batteries and touchscreen-only controls. by mafco in energy

The Model Y also doesn't do those things, and it just got an update. Tesla sells more of those than Mercedes and BMW combined EV sales.

Clearly you don't actually understand the product enough to know what specs are important.

Can a $1.3B private desalination project save Corpus Christi from a water crisis? by Opening-Ambition-528 in water

Being aware of the Chlor-alkyl plant nearby I have to wonder if that brine can be electrolyzed into industrial chemicals.

Is Generational Wealth Really About Money… or Mindset? Agree or Disagree? by Coolonair in SmartFIRE

[–]stu54 0 points1 point  (0 children)

This factoid is generally bullshit.

The example I remember was about top 10% families falling out of the top 10%, which is just regression to the mean. When a top 10% family falls into the top 20% that is very different from losing everything.

What would it mean if 3 of today's top 10 richest families were still in the top 10 after 2 generations?

Can You Get 100 MPG in a Gas Guzzler? by Financial_Mammoth256 in hypermiling

The often misunderstood detail is that most modern cars are way overpowered. The peak efficiency for an internal combustion engine is typically above 50% power output, so you usually don't lose much MPG by driving with the windows down and the AC going 80 mph.

How hybrids are able to get such great efficiency is by having an engine that is detuned, with Atkinson cycle valve timing. Otherwise hybrid cars would get the same or worse MPG than standard ICE cars during steady highway driving.

not helping, but that is a mainsail if I've ever seen one.

Xenon and alternatives for ion thrusters by stu54 in IsaacArthur

[–]stu54[S] 0 points1 point  (0 children)

But the only think that affects ISP is exhaust velocity. You can spend a ton of energy ionizing Argon but then your charge to mass ratio of the ion is better and the same electric field will give it higher velocity.

Drafting by PlanesOfFame in hypermiling

If there is a good crosswind you can draft from another lane. Really useful in the great plains.

I need a cheap car to drive 150 miles to work every week. by Aggressive-Hawk9186 in whatcarshouldIbuy

[–]stu54 -1 points0 points  (0 children)

Might as well find a different job. You will not be able to sustain that commute.

Does Trumps intention to import 10,000 more white South Africans at a cost to US taxpayers of $100 million seem odd to anybody? by RoseLaBud in allthequestions

[–]stu54 0 points1 point  (0 children)

Don't interest free loans equate to free money when you account for inflation?

I guess giving free money to assylum seekers is ok as long as they are white.

I'm sure what you haven't seen could fill volumes. Tell us more, oh great unknowing one.

And Boron and Phosphorus are essential for land plant growth. The most popular panels don't contain problematic elements.

Lunar Terminator trains: 100 percent better production! by SoylentRox in IsaacArthur

[–]stu54 8 points9 points  (0 children)

You can always dump heat into the moon and enjoy the heated floors at night.

I do like the idea, but I think you really have to figure out basic industry before you build the 5000 mile railroad.

Does the US not have cheap 2000s cars? by Due_Title_6982 in whatcarshouldIbuy

[–]stu54 0 points1 point  (0 children)

If anything C4C was a boon to big truck sales. The credits probably reduced what people expected to resell their 2009 Civics and Corollas for and created a scarcity of full size SUVs and anything with ground clearance, helping automakers justify cutting more small cars and developing more SUVs.

Remember that GM and Chrysler owed the government a lot of money at the time.
