Yes, I meant celluloid film for projectors. I suspect most paper fires in offices were due to people dropping still lit cigarettes into wastepaper baskets. I have actually seen a waste skip catch fire for a similar reason, and even when the flames were out it continued to smoulder, so we had to fill it with water and then drill a hole in the bottom to let it all drain.Quote:

Hi,
Celluloid film. Hmmm, at the risk of sounding old, I have worked with it. But only to try and recover some images from decaying rolls of 35mm movie film. Most of the 400ft rolls were too crumbly to get much off. Even the filmcanisters were fragile with rust.
The legacy of the flamability of celluloid nitrate film lasted long after its demise. The design of projector booths reflected the risk of running movie film through a focussed beam of light from a carbon arc well into the 1960s.
Small bits crammed in to a matchbox and lit from a smouldering cigarette made a marvelous smoke bomb if it didn't burst into flames.
So much mischief that we got away with, so long ago too.
Cheers
Big news perhaps? I added a Science Versus re bad news on beer, wine and more recently- Happily found a bright one for Alcohol[biggrin]
Happy Easter all- If My RAT tests are negative Disco is off to West Coast of Vic soon. ( Two covid + in my room yesterday- DOH)

Speaking of Science, but a tad OT, I happened upon an elderly bloke yesterday out side our Coffee Shoppe busting his pooper trying to Jemmy Bar an olde tangled Agapanthus bush out. 5 days beard growth, crappy old clothing etc.Quote:

I'm a plant Scientist etc etc etc I cant recall all his other qualifications & probably he was thinking "Hello, I've got a right plonker here".[bighmmm]
I guess he could have been a Rocket Scientist (you know "It ain't rocket science" stuff.
You can never tell a book by it's cover right? RIGHT.:rolleyes::blush:
OOPS! T i C of course.[bigrolf]
Does VIC. really have a North/South running West coast? More your South Coast I'd reckon, although some inlets do face West.Quote:

Yep, Cape Bridgewater just West of Portland has a North/South West coast - small maybe but it’s there and it’s in the West of the state not far from where ND is heading. [emoji4]
excuse the pun on Alternating Power or AC,
High Voltage Direct Current is not new. Making it work via software is and it is rather interesting Science
deleted wrong link sorry
What it is in a nut shell of cut and paste[biggrin]
"High-voltage DC power lines can transport significantly more power over greater distances than high-voltage AC lines. The two primary reasons for this are: HVDC lines can carry a higher voltage than HVAC lines with the same wire thickness due to the corona discharge and the skin effect. It's also possible to transmit about twice the amount of voltage in an HVDC power system in comparison to a high-voltage AC power system, which explains most of the advantages of overhead HVDC lines compared to overhead HVAC lines.
The ability for HVDC lines to transmit more power over greater distances gives it two main advantages over HVAC:
- HVAC transmission systems are limited to shorter power lines, meaning that more power towers must be created, which boosts the costs high-voltage AC transmission systems.
- Not only are there more power towers in HVAC systems, but the power towers are also bulkier and more expensive to construct than power towers in HVDC systems. The support needs to be stronger, wider and taller than HVDC transmission towers in order to accommodate for the heavy mechanical load on AC transmission towers, which makes them more expensive.

Australia is already using it!
- Basslink is HVDC
- Terranora interconnector is a underground HVDC

in theory "Dark matter is a hypothetical form of matter thought to account for approximately 85% of the matter in the universe. Dark matter is called "dark" because it does not appear to interact with the electromagnetic field, which means it does not absorb, reflect, or emit electromagnetic radiation"
that we cannot see it yet is very cool science Nasa suggestion of proof from the 1930s is still a great study
New telescope shoot up yesterday for research
"The Euclid telescope has successfully launched into space on a mission to understand some of the universe's greatest mysteries.The €1.4bn (£1.2bn) space telescope was primed to go up on a Falcon-9 rocket from Cape Canaveral in Florida on Saturday.
The launch is part of a mission that will make an immense 3D map of the cosmos in a bid to better understand so-called dark matter and dark energy.
Researchers know virtually nothing about these phenomena, which appear to make up the vast majority of the universe.
Although primarily a European Space Agency project, the mission has significant scientific and engineering inputs from the US space agency Nasa."
