"Jet fuel that begins life as air and captured carbon, the researchers explained, is completely carbon-neutral because the fuel only produces as much carbon dioxide as went into its manufacturing."
If they are talking about captured carbon from power stations and the like, no, that's not carbon neutral at all.
Most of it comes from fossil fuels.
the full android outlook caned my poor phone so much it lost all free space and was almost impossible to remove once in that state.
I wonder if I might risk it again....
It work want to email me something on my personal phone, well, they can pay extra for the space. So - I don't' do it. Even teams is disabled unless I'm travelling abroad.
Apart from Hydro, maybe we could harness some other type of potential energy?
I was thinking, 7 billion humans times the weight of their middle finger, hovering 2 inches above the shift key???
Anyhow, joking aside, the storage of this renewable stuff to smooth out the peaks is an issue.
Or else - only use it when you have it? So - no smelting or factories running except when the sun is shining or wind blowing? Maybe good old market pricing of electricity will sort that one out though.
Lastly, with this salty idea for air conditioning - what happens if it turns out cool the next day? Your investment in electricity is wasted. And - why do we need anything better than freezing and melting water? it seems like an invention for invention's sake.
I worked for a company called "CommsCo" back in the '90's.
They ran an audiotex bureau in North London, (i.e. dodgy porn premium rate lines - but - that's not the hot bit!)
Anyway one day the directors decided to "but some new kit", which they installed in 19" racks in the premises.
But - they also sold the kit on, removed it from said premises, put some dummy borken PC's in the rack, and set fire to the lot!
Then - they never paid the original invoice!
So - free kit, payout from the insurance, payout from the third party! Trebles all round!
Quite right, in the recent Sputnik auction, Breker wondered why I didn't bid. So I replied:
1. There is no accompanying documentation which would help to verify provenance.
2. Not even a letter from the vendor stating the circumstances of his purchase, date of purchase etc.
3. Only three photographs of the item were provided, and no internal photographs. No 360 degree coverage either.
4. Condition-wise a number of modifications were disclosed, but without more details of the modifications (such as schematics, detailed photographs, notes and/or an engineer's report) it is difficult to know how much of the original electronics remain.
5. Having compared the existing photographs with those of the most faithful reproduction I could find, a number of discrepancies were observed.
In particular around the antenna mountings and possibly the construction of the antennas. This is inconsistent with the requirements for EMC/EMI testing where the sample should be representative of the original.
However, a test report mentioning these differences would have gone some way to explaining this.
6. The construction of the casing shows 4 extra screws that are not apparent on any other photographs of other Sputniks (including those of the original Sputnik 1)
7. The construction of the stand isn't consistent with the 1957 Russian stand. I expect it was made later?
8. The original silver-zinc battery has been removed from the casing, but is not included in the sale. (I know this would have discharged long ago, but nevertheless it's an important part of the history.)
9. The mention of raspberries in your email was quite off-putting! But the whole story seemed to be quite surreal and didn't mention Sputnik once.
Finally, although the opening bid was reduced to 80,000 Euro verbally, the online ask bid was not. Although without documentation as mentioned above, I would have been unlikely to part with anything approaching 80k Euro, this may have deterred other bidders.
My Granny bought me a Philips EE1050. She was ahead of the curve!! Probably because my grandad was a proper electrical engineer working for the leccy board, but had died by then. (I still have his Avery)
I tried getting one on fleabay the other day - for old time's sake! And it would be interesting to see if I could actually make it work!!!
I know a few female electronics engineers, some quite specialist (RF too).
But you're right, the proportion is very low, maybe 5% or so.
I did a computing/electronics joint degree, and did end up mainly in computing, but the electronics side of it has always been present, and now I'm more on the embedded side of things working with pure electronics engineers it does make the whole exercise run more smoothly.
If you want to get back into it I can recommend getting a microcontroller, Pi/Arduino/ESP32/STM etc and then designing some electronics to hang off it, to interface with something, and the power supply etc. Make yourself a nice little project.
how we work, and "fill up" our cars.
Like the old days where you only got flour when the wind was blowing...
Factories and offices only run when the wind blows or the sun shines, and likewise, we charge our cars when there is sufficient excess renewable electricity.
Hopefully, variable electricity pricing to the consumer should take care of this. Use market forces.
When you are paying sensible amounts for your PV installation, the wiring does become a noticeable fraction.
I paid around £600 for 10 panels and an inverter, good for around 2kW.
Cable cost me around £24, which is 4%.
But if you paid (I am guessing) £3000, the cable costs are in the 1% area, not noticeable.
