Re: Methanol as a store of energy for a fuel cell
It's also quite toxic and easily absorbed through the skin. But it's an ongoing area of research. Ethanol is also a contender, and blends of various hydrocarbons are also being developed.

True. Cask temperature is best. But that seems to be considered warm beer by most of the rest of the world's standards.
And something nicely malty, nutty and brown. I miss the old Whitbread Forest Brown Ale... Timothy Taylor's Landlord is close-ish, but less nutty.
I have a large box of old hard drive under my desk - I remove them from machines that are being retired for security purposes. The central IT lot want them ground up... they take up only the space of a small lockable filing cabinet that doubles up as a coffee machine stand, and it still has plenty of room in it.
When I was 15 I applied for funding to buy one of them and a BBC plus a specific model of video recorder that was easy to hack. The idea / purpose? To code a method of setting a VCR programmer using Ceefax/Teltext program listings and adjust the start and stop times automatically if the program start was delayed by say an over-running sporting event. I had a rudimentary 6502 machine code program already written to handle the user interface and control the tape transport system - I just needed real teletext data, a BBC to work on at home instead of writing it all at school during lunchtimes and a VCR with full solenoid control instead of just a prototyping board stuffed with optoisolators and LEDs.
Funding request was rejected but two years later the first PDC VCRs were launched followed shortly after by VideoPlus+ program code machines. Im not sure if this was connected or not!
Which is complete bullshit because only last week I had to upgrade a 2014 iMac and could only get it up as far as 10.13. Which fixed about 80% of the websites that wouldn't work correctly but of those that still wouldn't most of them were for our corporate intranet. I may have exaggerated the life span in my first post but not that much!
And we never had any students paying for a full print run on the Heidelberg either! They only saw their work come off there as part of a teaching exercise, and we usually had to do those as individual A5 pages with imposition up to an SRA2 sheet size ready for print finishing to turn them into exhibition booklets for the end of year show.
We did have quite a few who paid for a print run on the digital press though... custom wedding and party invites and the like. That only went up to SRA3 though, so it was no good for big posters.
I find that with laser printers too. It's rare to find a series of printer which use interchangeable toners for a very long time - it's like every new model has a new shape of toner. We've got a number of semi-independent groups here, so funding comes in in drips and drabs. They all want their own printer, and buy one when they get the funding, but it will use a different cart to their neighbour, which means you can't keep a stock of one type and if it runs out in the middle of the night, there's no nicking one from someone else and replacing it later!
The longest chain of compatibility I found was in the HP 3000 series, where the 3600 went through about 4 or 5 revisions over a 5 year marketing life and was replaced by the 3800 which used the same cartridge and lasted another 5 years of currency or so... after that, the next model at that price/use point lasted about a year or two of being current and it used a different cartridge format again - repeated to this very day. I've given up trying to standardise all these different groups - reliable just-in-time ordering meant I could get away with it. With current logistics problems we may see longitudinal service life become a plus point again - it allows you to keep a stock of bits in to absorb any hiccups in the supply chain.
Cost and size, essentially. Our dye sub (a FujiFilm proofer, can't recall the exact model now) would set you back £18.00 for an SRA3 print (maximum size), whereas the inkjet was only £8 for the same size. We didn't do a lot of photo printing either - mainly graphic - large blocks of solid colour. Even a dye sub can have problems holding big areas of even colour.
If you wanted an SRA2 proof on the inkjet it was £20.00, but if you wanted me to run off a SRA2 film and a Chromalin, that would cost you about £80... £10 for the film, £70 for my time and we threw in the Chromalin toners, laminate and board for free (we had a number of very generous donation of surplus stock from various manufacturers, stockists and pre-press houses who decide to get some shelf space back when they finally went fully digital)!
I've always encouraged people to use proper coated papers for inkjets - the regular papers and worse still the ones that have been minimally calendared if at all have a surface pill of fine fibres that can poke up and block the nozzles. I worked for the best part of a decade in a college of print and design and saw thousands of students through their various courses. We ended up having to lock the (expensive photo quality SRA2) inkjets away to prevent students using regular laser paper scavenged from the paper trays in them. It cost a fortune to maintain the printers - we only used manufacturers inks and papers - it was the only way to maintain the quality. The ones that were nearing the end of life we used to use for more esoteric duties - printing onto weird surfaces like foiled paper, waterslide transfer and vinyl.
Do you mean a printed poster? Do you know the carbon footprint of making paper, ink, printing etc?*
*Answer - it's a lot, lot, lot less than one of these Digital displays. Not so sure on the carbon footprint of sending a Jo-in-a-van out to change them once a month, though. Mind you, given the amount of printed paper that last came in the box with a computer & Windows installation... in every language possible...
No need to be insulting.
Some good ideas. however, about enabling persons with various physical conditions to make use of technology.
The invisible scroll bar DOES do exactly what you say anyway! Try it with the BBC News app - scrolling down with your finger too near the right edge of the screen causes the page to leap about.
I was also talking about the computer OS, not the mobile OS.
This.
The aim is to allow research questions to be answered - the method proposed it to essentially sell the raw data, suitably tagged so as to prevent the same individual from being double counted.
The other way to do it is to run an "air-gapped" service which will perform the analysis and present the results, but that's likely to be far more expensive. Those interested in buying the data will no doubt complain that it's too much, and appeal to the powers of capitalism.
So you have to know what the ACTUAL question is before you can understand the answer...
Makes sense. If the root of the root of the question was "How can I stop my children getting COVID?" then the condom answer makes sense. After all, there's a billion things a person could avoid worrying about if they didn't have any children in the first place!
