Metal hot. Make food hot.

Think a bit deeper. How quickly is that heat transferred, and at what peak temperatures? Does the metal keep any heat of its own and impart that into the food, or does it just convey the heat from the burner to the food? And how quickly does it do that?

but my wife seems to think cast-iron is necessary for certain things (searing a prime rib roast, for example.).

Look at the thermal mechanics of this.

Take the cast iron pot. You can throw that on the stove and let it get ripping hot, like the metal itself is carrying a ton of heat energy. When you put the prime rib in it, the metal dumps its heat into the meat much faster than a flame alone would. This helps you get a strong sear on the outside, without dumping in too much total quantity of heat to cook the meat on the inside more than you want.


then I gotta figure out gas vs. electric vs. induction vs infrared…

Heat can be transferred 3 ways- conduction (flows between two touching objects), convection (hot object heats air, air blows against cold object, air heats cold object) and radiation (hot object radiates energy through space and it warms cold object).

Electric- coils get hot, the pan touching the coils transfers heat by conduction. Downside is uneven heating- neither the pan nor the coils is perfectly flat so you get hot spots.

Infrared- coils under the glass get hot and radiate heat through the glass. This works pretty well.

Induction- coils under the glass but they don't get hot. Instead they create a magnetic field modulated at low radio frequencies (15-150 KHz). This fluctuating magnetic field interacts with any ferrous metal close to it, creating small but powerful eddy currents inside the metal and thus heating the metal up. So the stove doesn't create any heat at all, it's the pan that actually gets hot. This by the way is neither conduction convection nor radiation, because heat isn't being transferred, it's created inside the pot.

Gas- flammable gas (usually propane or natural gas, which is mostly methane) burns creating high temperature exhaust gases that rise against the pot and thus heat the pot. Many chefs like this. Gas stoves should ideally be used with an overhead hood as gas stoves have been proven to drastically reduce indoor air quality.

Of the options- induction is usually the best these days, because it's the most efficient, cleanest, and also in many cases has the highest output (in terms of watts of heat pumped into the pot).

When cooking, you want a stove capable of very high output. The more output you have, the faster it will boil water for example.

I couldn't agree more. Acting like a million dollar company is important.

A million dollar company would recognize that reliable, continuous production and sales is more important to growth than the occasional hickup or a few extra bucks in the payroll budget. Thus, the million dollar company would hire sufficient staff that an occasional absence, even at a critical moment, would not harm production or sales.

And a million dollar company would recognize that hiring sufficient staff is a wiser and more cost effective strategy than a possible labor lawsuit along with the associated bad PR.

Exactly!

If releasing a list of people who raped children would hurt those people, then I say too fucking bad maybe they need to be hurt a little bit.

There a saying-- only do one crime at a time.

This guy was growing weed and doing just fine at it. Only because he decided to steal power also, he got caught.

If only that was a legal cause of action...

What's there to sue for? Companies shut down product lines and brands all the time.

Or that Ukraine is holding them off with basically scraps of obsolete Western military equipment, very little first line hardware. Attack Europe and you find the full weight of NATO's first line military hardware shoved up your ass. Somebody pushes a button somewhere and a few dozen Tomahawk missiles destroy your ability to wage war in an afternoon. Nukes not even needed if every airfield and military supply depot within 500 mi of Europe is a smoking crater.

Except the Democrats have basically just announced they are going to do nothing because their efforts wouldn't go anywhere. So better off not trying.

[–] SirEDCaLot@lemmy.today 13 points 5 days ago (1 children)

And this is why I have no faith in Democrats. When it comes time for the fundraiser they are all red alert sound the alarm Trump is destroying our country, when it comes time to actually fucking DO anything it's excuses and business as usual.

If the guy literally did order a war crime, then file the fucking paperwork and dare the Republicans to quash it. Make sure that every one of them who fights against this does so publicly, on the record. Make sure they know that if/when the truth comes out, be it tomorrow or years down the road, their vote today will be known to the world. And they can bet their asses that 'senator whatever chose not to investigate war crimes' Will be part of their opponents' campaigns.

That's why I said, different approaches.

My approach is targeted at somebody who just wants to get clean as quickly as possible, and the machine can help them do that faster and with less effort than a manual shower.

If you are going for luxury, or if you need help doing it like an elderly person, then the sit-down submerging spa is absolutely the way to go.

How so?

I think there's two different approaches to this. This chair is obviously designed as a luxury experience, as the process takes a full 15 minutes.
My idea is designed for efficiency, to reduce the amount of time it takes to bathe in the morning without reducing cleanliness.

Interesting idea. Seriously over-engineered though.

If you want a 'human washer' you don't need a $350k fancy chair with heart rate monitors. Just take a page out of the automatic car wash.

Human stands in a stall. Shower allows human washing of hair and face. Then just hold arms out making a diamond in front of you (think TSA body scanner position, but with arms forward instead of upward) and a 360° robotic sprayer starts at the neck and goes down spraying soapy water, then back up again with a slight up angle to get the groin and armpits. Shower comes back on to de-shampoo hair, then the same 360 robot does two passes with clean water to rinse everything off.

If you get fancy with machine vision and body position sensors, the 360 wand could flip 90° to do the hair and would be angled backward a bit so it doesn't get water or soap in your face.

You could build this for a lot less than $350k. And instead of $1500 worth of body sensors you have a $50 waterproof emergency stop button.
