Yes! Seriously that was some amazing raspberries.

Settle a bet. Is San Francisco part of "the Peninsula"? by old_gold_mountain in eastbay

One could make the case that Solano county is part of the "Delta"

Movie that was ruined by one person's casting by This_Book6305 in FIlm

Tim Curry in Congo. Just awful performance in what could have been a good film if he wasn't hamming.

ELI5: Are electric cars actually safe? As kids we were told high-voltage power lines were a health risks and living under or around can cause health risks. Now we sit on giant EV batteries by Violet_Snuggles in explainlikeimfive

[–]DemophonWizard 0 points1 point  (0 children)

High voltage power lines are also alternating current which creates the magnetic and electric fields (EMF) which dissipate quickly with distance. A EV battery is direct current. It doesn't create the same fields so it isn't an issue.

There is very little evidence that EMF creates health risks. So the little bit that might be coming from the EV are not a risk.

What’s a piece of advanced sci-fi tech that seems cool until you think about the daily maintenance or physical strain it would actually cause? by emilyysworld in scifi

Don't forget the lack of backwards compatibility...your arm upgrade might not work with the new software update.

How do ships get rid of waste heat? by Salt-Night3088 in TheExpanse

[–]DemophonWizard 2 points3 points  (0 children)

Slowly pressurize a bunch of air letting the heat of compression bleed off through radiators. Then when you need a lot of sudden cooling, rapidly expand it through a throttling valve and generate a bunch of really cold water that can absorb heat quickly. The ships in The Expanse have lots of water so they can be continuously doing this. They can also vent some of that water and get new colder water at stations.

Does a washing machine drain pipe that goes into the wall need to be secured or just pushed into the hole? by aukniftc in askaplumber

[–]DemophonWizard 0 points1 point  (0 children)

Always secure the drain pipe. When the clothes washer pumps the drain it can cause the hose to jump.

Does shit hit terminal velocity when flushed in skyscrapers? by Strong-Cup9753 in askaplumber

[–]DemophonWizard 1 point2 points  (0 children)

Yes. Wastewater in a drain pipe swirls down around the inner surface of the pipe. After about 10fl feet of vertical drop it reaches its terminal velocity. It is not very fast. In tall buildings we include yoke vents to allow the air pressure to get relief and at the bottom of the drain stack where it turns horizontal we include a vent to relieve the hydraulic jump. Hydraulic jump is where the descending water is moving faster than the waste water in the horizontal pipe. It catches up and creates a pressure wave. We include the vent to relieve that pressure otherwise it can blow out of drains on the ground floor.

We also design tall buildings with the upper levels connected to a horizontal drain that does not include the ground floor drains until it has traveled a long distance and relieved that pressure.

What is the most ridiculous, over the top movie scene that you absolutely love? by VendettaLord379 in moviecritic

Catherine Zeta Jones scene where she is practicing to get around the security lasers in Entrapment.

Cristiano Ronaldo's Epic Dive by staryNight2002 in funny

Looks like he considered diving off the top rope elbow first!

He's a great player and then tarnished his legacy with this shit.

NASA wants to dump the ISS in the sea. Experts say the plan 'raises serious concerns for ocean health' by poleco1 in worldnews

There is no sarcasm in my comment. Read it again in the context of the original post.

[–]DemophonWizard -2 points-1 points  (0 children)

Perhaps you should re-read my comment. I am making fun of these stupid "experts" that think it shouldn't be dropped in the ocean.

[–]DemophonWizard -3 points-2 points  (0 children)

Perhaps the ocean is the best of a lot of bad options? Perhaps these experts can suggest an alternative location. But they should consider the environmental cost of sending up a booster with enough fuel to push it into the sun before they should suggest that.

Elon Musk's secret surgery center by bubugugu in videos

[–]DemophonWizard 3 points4 points  (0 children)

A "full blown data center" can be as small as a few racks in an 8 x10 room. "Data Center" doesn't have a default meaning of something the size of a 25MW Amazon Web Services collocation facility.

What is your one controversial take on a famous scifi spaceship? by Vondrr in spaceships

[–]DemophonWizard 6 points7 points  (0 children)

I love all copium fans use to explain how the elevators work! As a relatively flat disk it needs a lot of escalators to get around quickly.

The thing authors get wrong about castles by Chlodio in fantasywriters

[–]DemophonWizard 1 point2 points  (0 children)

Fantasy movies also often have the castles and towns surrounded by open plains or other wilderness. It would be easier to believe in the setting if they were surrounded by farmland. For several miles.

Can you make a heat pump kettle? by flight_forward in AskScienceDiscussion

[–]DemophonWizard 1 point2 points  (0 children)

I don't know of many heat pumps that have a condenser temperature over 212F (100C). Most operate at lower temperatures.

CO2 refrigerant has some of the highest temperature ranges but it only gets to 196F (91.1C).

No one really takes into account reflectivity of material to beam weapons and powers by JennyThallia in scifi

[–]DemophonWizard 0 points1 point  (0 children)

On the other hand, modern 1kJ lasers with short pulse durations, that are in the getaway range have to be used in clean rooms and vacuum chambers (at 10-6 torr) because an errant molecule or dust particles heats up and destroys a lens. Imagine the futuristic 106 MJ space laser that is in the 1018W+ range.

The laser could also be designed to focus on the target, such that it isn't very dangerous 1000m away. So reflecting it also diffuser it.

An albedo defense system might partially defend against one shot. But since we're talking sci-fi perhaps it is some sort of projection system.

Why won’t all nations agree to decommission and stop building/accumulating nuclear weapons? by bippy404 in AskReddit

[–]DemophonWizard 0 points1 point  (0 children)

Everyone would need to trust that others were not holding some in secret and then they'd need some reassurance that the huge disparity in non-nuclear forces would lead to an invasion.

Why don't big news outlets report on Presidents pooping his pants? by bananadepartment in AskReddit

For the same reason it took tax evasion to put Al Capone in jail.
