#TruthBeTold #time #day #solstice #astronomy #sidereal #ISS #relativity

The truth is...

A day is 24 hours long, plus or minus about 20-30 seconds. However, during the winter the days get longer. At the winter solstice the days are the shortest.

But the southern hemisphere is different. In the southern hemisphere the days are nearly always 24 hours (+/- about half a minute).

And on the equator it gets really weird, because a sidereal day on the equator is only about 23 hours, 56 minutes year-round. And at the north and south poles, occasional the day is a second longer (leap second), due to climate change, among other reasons.

In space, astronauts experience time differently because they are in an area of lower gravity due to general relativity. For example, the International Space Station experiences 16 sunrises and sunsets per Earth day.

In areas where there is daylight saving time, on the day those areas enter daylight saving time the day is 23 hours, and when it switches back to standard time it’s 25 hours. These short and long days only occur in the areas where there is daylight saving time which you’d think would cause massive geological strain on the Earth’s crust and upper mantle, but for some reason it doesn’t.

**** movie spoiler - Looper (2012) ****

In this film a crime syndicate in the future sends people, who they want to kill, back in time to the present, where they have hired present-day assassins who kill them. The assassins kill the victims, whose heads are covered, as soon as they appear after the time-travel trip to the present. (Apparently the bad guys do this to avoid having bodies to dispose of in the future.)

A twist to the plot is that if any of those present-day assassins live long enough to be alive in the bad guys' future, the bad guys will kill the assassin to make sure there are no loose ends. The way they kill the assassin is to send him back in time to have him killed by his own younger self. They call this "closing the loop".

Yeah, this has been going on for a long time. Ever since the industrial age started. I think it's build in to DNA of economic competition.

I think it will become less so as we shift toward distributed manufacturing, 3D printers in every home, replicators, etc.

You know, it's ironic that the term "quantum leap" is usually used to describe something that has advanced significantly. But quantum is mostly associated with small things so "quantum leap" really means a small jump.

Also, electric cars take much less energy to manufacture than putt-putt cars do.

Putt-putt cars also use more energy to maintain them.

Here's an idea. Instead of virtue signalling, celebrities like Rainn Wilson could, you know, actually reduce their own horrifically huge #CarbonFootprint if they really care about #ClimateChange or think there is a #ClimateEmergency

@taz I agree the name change thing is dumb, but I don't think *anyone* changing their own footprint is gonna solve this, so that's also really just virtue signaling as well.

Maybe. It depends. But even in the extreme, where all of it was produced with gas/oil, an electric car is still much more efficient than a putt-putt car.

Also, going forward, more and more electricity will come from renewable sources.

Renewable technology has a long way to go. It will get there but it's going to be a while yet.

When you take into account the ecological impact of creating and later disposing of the batteries in EVs, they don't fare much, if any, better than the current internal combustion engines in cars today. That's without even beginning to take into account the batteries used to store renewable energy for later use.

Besides, you don't really own that electric car. It is permanently tethered to the home planet and they can shut it down or lock you out remotely.

Actually, they don't. I get 4-5 mi/kWh. Work it out -- it's just fraction of CO2 footprint of a typical putt-putt car.

@Pat @taz 0.08 gallons of petroleum per kWh. At 4 miles per kWh, you're at about 50 miles to the gallon. Which is directly comparable to pretty much every hybrid available, and not that much worse than the traditional economy vehicles.
Now, if you get solar panels installed on your house to charge your EV, that's *actually* doing something. But the sad part is, it still isn't enough, because the earth is really really big and our individual choices don't make a bit of difference. The change has to come from the top and apply collectively.

That eia number is not for cars, it's just energy. Cars mostly turn the energy from gas into heat, not miles. The EPA number is 33.7 kWh/gal, which accounts for the inefficiency of putt-putt cars.

>"We're talking about how much petroleum *power plants* use to power your car. They burn the gas just like my car does."

First, a lot of the power doesn't even come from oil/gas, it nukes, wind, solar and bunch of other sources, depending on where your electricity comes from.
Second, they "...burn the gas just like my car does." They don't burn gasoline, they burn natural gas usually, and they don't use inefficient pistons, they use turbines to power the generators. It's not the same at all -- it's much more efficient than burning fuel in a putt-putt car.

And if what you say is case, why does it cost so much less money to power an electric car? If the power plants have to pay for the fuel, why is it so much less to use electricity? Ans: Because they are not wasting all that fuel like a putt-putt car does.

Plus now solar is much less than other sources, so the market will switch over quick enough.

BTW, if you live in CA where the cost of electricity is second highest in the country. Your $3 only buys you a little over 11 miles of range making it almost exactly on par with $7 per gallon gasoline.

EVs are the future, maybe. But they aren't the nirvana you wish them to be.

I'm there already, for years now. I've been driving my electric for years now and it's just great:

- it's pennies/kWh instead of $4.00/gal
- Virtually no maintenance
- Very quiet
- Better performance (high torque)
- I don't have to stop at a gas station to fill it, I just plug it in at night like a cell phone
- I don't get smelly gas all over my hands and clothes
- I don't have to breathe in those smelly fumes at the gas station
- I don't start it up or warm it up, it just goes
- Don't breathe in that smelly exhaust

@WilliamRamsey

I was thinking about maybe putting the filter on the outside to filter the air as it went in, so as not to disturb the airflow within the case. They plan out air flow pretty carefully so it keep the right components cool enough. If the filter is on the air going in, then all you'd have to do make sure the cfm of the fan/filter combo was the same.
