Why do TV reports about global warming and carbon emissions always show images of steam rising from giant cooling towers?
Presumably because to the uninitiated it looks like s
tloads of smoke.....although the heat that's been generated to create the water vapour will have probably been created through the burning of coal or oil so there is a loose visual relevance.

In Top Gear’s ‘challenges’ where Clarkson drives the Bugatti or Mustang across Europe and the other two take public transport, you always see the LR Discovery camera car in front of Clarkson.
Do they use several camera cars or is the Disco always in front of the Bugatti etc therefore doing the journey just as quickly?
They do the interior shots with Clarkson going out, then go back to do the outside shots later with one of the production crew driving.Do they use several camera cars or is the Disco always in front of the Bugatti etc therefore doing the journey just as quickly?
Most cars will be just as fast as a Bugatti on those trips because going much faster than the speed limit will attract attention from the police.

Something quick and easy thst the plebs can easily relate to I'd guess.

How do steel pans (steel drums) work?
I don’t understand how hitting different parts of the same thing produces different notes.
If you look closely at one you'll see that they are faceted. Each facet is tuned to produce a different noteI don’t understand how hitting different parts of the same thing produces different notes.

Reminds me of the times when Michael Palin is in Africa, travelling with one cameraman: We see Palin get on a train and train drives off, leaving camera crew behind... next shot is inside the train, crew is with Palin... I bet 1,000 people in a hurry to get to Timbuktu were really happy the train had to stop and reverse back to the station to pick up these timewasting foreigners.
That happened to me in India with an American film crew. The locals thought it was great fun and did everything possible to make it look good. Personally I didn't care; I was getting paid either way. But it took all day.
I loved India with all my heart FWIW.

I would imagine that each strike produces two (at least) notes. One being that of the whole pan vibrating, the other being that of the particular facet which has received a hit and is resonating. The resonance of the tuned segment thus being the louder tone and the one your mind focuses on. The other tuned segments of the drum are sized to resonate at different frequencies and thus will not resonate with the frequency added by the section you've just hit.I don’t understand how hitting different parts of the same thing produces different notes.
In a similar way, if you play and quickly damp a note on an acoustic guitar, you'll hear the rest all humming in some form of sympathy, but nothing like as loud as the string you have just directed the energy to.

By the way, agree fully on India, I lived there for a bit and miss it every day.

Some years back when Lotus were still in F1 (as in the Grosjean era), they were doing a filming day at Brands Hatch and I happened to be nearby so dropped in for a look.
They had a Merc' GLE AMG with a boom arm and a £50k RED camera dangling from the end. Whoever was driving it, Lotus would have done well to have signed the guy (or girl) up. Seriously, seriously quick even with all the gubbins on the top and dangling - proper tyres trying to pop off the rims stuff. I doubt the F1 car got out of 2nd but the speed was still mightily impressive.

Same with all the roadside shots. They don't have a bunch of crews on the route to hoping to get a decent shot real time, they film it later with one crew and a bunch of takes.
We watched the filming of episode of Mock The Week some time back, the bit where they go across to the other side of the studio to do the standup bits is filmed twice as they don't have separate cameras there, so film them getting up and walking across, and then move the cameras and do it again to show them arriving

After Fred's death, the producer of those shows wrote a book about their work together. It revealed that in most cases Fred was driven between venues by car, while the traction engine went on the back of a low-loader and was unloaded to film a minute or two of Fred driving past a particular landmark or in through a museum gate. (Though as steam engines take hours to get up to working temperature, this was still probably very time-consuming.)
