Actually, if Vince were to do that muticamera setup I was tossing around there, he'd need a video switcher. And that's where the waveform monitor comes in, because as soon as you add a video switcher to the mix, it opens the door to all kinds of timing problems. PAL's nicknamed Problems Are Lurking for a reason!
Once it's all sorted out though, he can have some "talent" in front of the cameras doing a debate about whether tap water can be considered 100% ethically sourced vegan or not.
I am set to bid on this Racal Dana 1998 Counter:https://www.ebay.co.uk/itm/393856305682no photos of the rear panel. I am assuming it has the least desirable options.

PAL's nicknamed Problems Are Lurking for a reason!I'd rather have that than Never Twice (the) Same Colour. For a multicamera setup one needs sync distribution, or the switching will be rolling. The W/V meter will help with signal quality and integrity, and will be useful to EQ the DA for the blackburst, but sync is a timing thing more than anything else.

Now chemistry is not my strong suit, in fact I know almost zero about it, but some of you do it seems, so what are your thoughts about this Aluminium-Air Battery, does it actually work and if so, is the possible future for EV vehicles?
Even with good sync to all devices that require a reference input to be genlocked, video switchers are notorious for introducing timing problems into NTSC systems due to propagation delay. If Vince moves here, he can have fun with nice, even frame rate numbers that are ruined by multiplying by 1000/1001
while trying to figure out why the flesh tones on the reporter in the studio have suddenly turned purple while they were hyping up the audience by telling them that even if they're all feeling ok, it doesn't mean they're healthy, it means they're asymptomatic and that if COVID-19 doesn't kill them, something else will, so keep watching - details coming after the next commercial break - DON'T TOUCH THAT DIAL!
I may be vile and perniciousBut you can't look awayI make you think I'm deliciousWith the stuff that I sayI'm the best you can getHave you guessed me yet?I'm the slime oozin' outFrom your TV setYou will obey me while I lead youAnd eat the garbage that I feed youUntil the day that we don't need youDon't go for help . . . no one will heed youYour mind is totally controlledIt has been stuffed into my moldAnd you will do as you are toldUntil the rights to you are soldThat's right, folksDon't touch that dial!
fun and games and Murphy hitting me in the crotch ...coolant warning light came back on yesterday on that Volvo again. Coolant missing.all that while I still had to return the trailer ...my former neighbor gave me his car and I was able to get rid of the trailer. scrawled back to the Mechanik who said that he was refusing further work on the car. he said that he suspected a ruptured head or head gasket. that would coincide with the white fog coming Out of the exhaust.FML

For the german speaking crowd, there is this new podcast called "Geladen" about battery technology from university karlsruhe:https://geladen.podigee.io/They had already some intresting facts in the interviews with experts, like:- recycling LiPo batterys does get you stuff like nickel, copper & cobalt but not the lithium itself back(it goes into the slag when melting)- H2 cars (like they are shilled in germany strongly) need to go for a safety checkup of their 600 bar gas system every 10k kmand so on. Good stuff!

What could possibly go wrong!Start by thinking of a puncture/cut in a collision. If that doesn't raise red flags, consider a grease monkey repairing it afterward...
I see no problem with H2 powered vehicles.
That would have been helium, as per the original design, if the US hadn't refused them an export license for the helium which caused a redesign. As Michael Caine would apocryphally say "Not a lot of people know that!".
Also re: petrol vs diesel torque, the way they output torque is quite different. Petrol engines do it at a much higher rev range which means by the time the torque is there, the angular velocity is such that it breaks traction very easily.
