turboplanner Posted December 3, 2023 Share Posted December 3, 2023 (edited) WS00275.pdf Here's some information as of two days ago on a Hydrogen refuelling station for HICE. These are the vehicles the Chief Engineer of Toyota was talking about, where the technology allows ICE car and truck platforms to use the existing ICE tooling, so a much simpler otion available much faster. Note the size of it - too big for just an extra pump at a petrol/diesel road house, so Infrastrucure is a factor in a future of ICE as it is with EV where people so far have been telling us they were able to pull in to a petrol/diesel roadhouse and thier car was charged while having lunch. There are already stories out there about queues and broken chargers, but the big elephant in the room is that if there was a big take up of EV, even with the 30 minute charging that's being boasted about, the real estate footprint of a roadhouse trying to park the same number of cars which will take up the charge point from half an hour to several hours in not viable where the existing footprint copes with an average 5 minutes per fill of petrol. Infrastructure killed LNG and that was just a small conversion. Edited December 3, 2023 by turboplanner 1 1 Link to comment Share on other sites More sharing options...
LoonyBob Posted December 3, 2023 Share Posted December 3, 2023 HeyCarbon Canary, that SiBox sure is interesting; but I'm pretty sure a gram of SiBox weighs more than a gram of lead! 😛 I thought drag coefficient was a convenient equivalence, based upon the ratio of the maximum cross-section of the body in question, to the area of a flat plate of negligible thinkness which would create the same turbulent (accelerated) wake; except in the case of an airfoil, which is irrelevant to car design... Road vehicle power requirements are generally considered to be the sum of the fluid dynamic drag, the rolling resistance, and any effective acceleration/deceleration due to slope or pilot input. The efficiency of the powerplant per powerplant is a seperate issue. 46.5MJ/kg is the target for batteries, and we ain't there yet... Link to comment Share on other sites More sharing options...

Interesting that people use words like "de-carbonising" when for every atom of Carbon we eliminate, we also eliminate two atoms of oxygen. I am blown away at the intellectual sophistry to make such a comment. Having a science background was clearly a waste of 40 years of study and in-depth interest.

Where does CO2 come into this "elimination" concept? What do you mean by eliminate?. Nev Actually, there are so many allotropes of carbon, they are divided into classes.

And here was me, thinking that Duramold had been made obsolete by carbon fibre and Kevlar? Any wood/phenolic material cured under heat and pressure, exhibits a fatigue limit, unlike any Carbon or Boron/Epoxy. Also, it is not susceptible to post-impact fatigue, unlike etc. Check out the TC'd "Micarta" prop for Bonanzas... ANYway, that there Goose has a big negative carbon footprint, AND is big enough to lay a coupla acres of solar cells on top... how Green do you want???

And if you do a bit searching you will find the latest designs under development are quite different to whats out there now. But I should add a disclaimer. I don't know much about anything,I just read what I can . Edited December 4, 2023 by BrendAn 1 Link to comment Share on other sites More sharing options...
facthunter Posted December 4, 2023 Share Posted December 4, 2023 Far fetched you think? Solar arrays are hard to wipe out enough for the attempt to be worthwhile/ Only Nuclear spreads the degree of poison that makes it a really good idea from the attackers view point, really. You wouldn't be able to go near the Area for years. Look at the cost of power from nuclear and the time to build one 2 Link to comment Share on other sites More sharing options...

Look at the cost of power from nuclear and the time to build one we are in australia not eastern europe. things have come a long way since the first nuclear power stations . you can't even tell me what will replace coal for industrial power. its not solar or wind. maybe hydro but thats pretty limited in australia. 2 Link to comment Share on other sites More sharing options...
onetrack Posted December 4, 2023 Share Posted December 4, 2023 The only thing I can see in my crystal ball is that our power/energy sources will become a lot more fractured/diverse in the next couple of decades - and that's not a bad thing. Nuclear power stations means we're putting a lot of eggs into one big basket. 1 Link to comment Share on other sites More sharing options...
facthunter Posted December 4, 2023 Share Posted December 4, 2023 Solar is SO cheap here and plentiful. that we could use it to produce hydrogen or concentrate it to achieve otherwise unachievable temperatures. with NO nasties.. One sub with 5 warheads is all it takes to end the Power stations We don't have to be IN Europe to have the lot knocked out in one go.. Plenty of ways to store energy. A Funicular railway, Big flywheel Pump Hydro. Batteries are instant. Changing output on a nuclear plant ISN'T. Nev 1 1 1 Link to comment Share on other sites More sharing options...
