This is how I can tell it's hambone because he clearly doesn't visit any other part of 4chan. Don't forget he's been banned and outed on other forums with actual moderators for making sockpuppet accounts.

Guys... As an outsider, this thread is totally lost. You can't, through any social engineering, find out if a poster is habone or if he's just making ham one posts

Why do you bother to try? It's like you want to get pissed off
>>
>>1601230
Hambone has a known history of being an austist and throwing shitfits on any forum he can find (slowtwitch, weightweenies, etc.), then making sockpuppet accounts to defend himself with, which also get banned.

This is all very documented and it's very likely this is him because this is the one "forum" where people won't get mad at him for saying bad words (his victim complex shows though and he accuses people on 4chan about being offended by bad words like on actual forums) and the one "forum" mods won't ban him for making an ass of himself.

This behavior of pretending to not be himself, his unfamiliarity with 4chan norms and memes, his victim complex (who is seriously going to accuse 4chan about being offended by bad words), the attention seeking, and resorting to insults are all very consistent with his behavior on other forums. If you search /n/ history, he keeps spamming shitthreads like this every time he makes a new video. He actually believes all the people that are sick of his attention whoring are a single schizo, and most people here actually like him because he gets a handful of positive posts every thread.

GWR thread

https://en.wikipedia.org/wiki/Great_Western_main_line

The Great Western main line (GWML) is a main line railway in England, that runs westwards from London Paddington to Bristol Temple Meads. It connects to other main lines such as those from Reading to Penzance and Swindon to Swansea.[2] Opened in 1841, it was the original route of the first Great Western Railway which was merged into the Western Region of British Railways in 1948. It is now a part of the national rail system managed by Network Rail with the majority of passenger services provided by the current Great Western Railway franchise.

The line has recently been electrified along most of its length. The eastern section from Paddington to Hayes & Harlington was electrified in 1998. Work to electrify the remainder of the route started in 2011 with an initial aim to complete the work all the way to Bristol by 2016, but in that year the section through Bath to Bristol Temple Meads was deferred with no date set for completion because costs had tripled.

Nope.
Churchward was the high point, a man who could see good ideas and was willing to experiment. Then they got complacent and thought that welsh coal would always be cheap and available.
If they had taken notes from France/LNER with draughting developments or higher superheat their locomotives could have been extraordinary.
Instead we get repeats and variations on designs that are already 20-30+ years old from Collett and Hawksworth never really got a look in before BR took over.

Nah, there have been many small helium and hot air transportation for a few people since the end of the Kike Ages.

There are very few of those with proper research and development done to them for juicy reasons.

About hydrogen safety, and posts about it get deleted for some reason, you can also find a way to eject the gas (maybe quickly disassembling segments of the balloon), avoid oxygen getting in, burn it all using a lot of oxygen so it doesn't explode (inside a flame proof coated material or ejecting it), ...

Hydrogen generators also release oxygen and it can be easily separated. It's also a very efficient process so most of the consumed energy is still available to be used in a heating system, generator or other chemical reaction.

> other researchers also tested this on jet fuel, but most research is about diesel
> the amount of water can be very high, from 5% to 40%, both on diesel and jet A
> if you need a stable fuel for storage, lots of emulsifiers are necessary
> if you have a mixing apparatus onboard (steam emulsifier, shear mixer, ultrasonic mixer, ...), only water and fuel can be used, mixed and sent to the engine
> the results are sensitive to which mixing process, emulsifiers and other details are chosen
> there are many improvements in emissions, temperature, fuel consumption, costs, ...
> it's a very old concept that got "juiced"
> usually unmodified engines are used, but in this research from the 70's it didn't work

There are other methods to obtain pure oxygen:

https://archive.nyafuu.org/n/thread/1536572/#1561493

Metal-Air batteries also need pure oxygen in one of their electrodes, using air filters to obtain it:

https://www.technology.matthey.com/article/62/2/134-149/

Of course there are other electrodes, air filters, metals, electrolytes, ... not mentioned in this overview. And the incomplete list of metals shows there are other promising alternatives to Aluminum, Zinc, Iron and Lithium, which are the most commonly used. Specially when it comes to efficiency and complexity of recharge.

Compressed natural gas requires less changes, but this still looks viable:

http://gjar.org/publishpaper/vol2issue2/d154r58.pdf

The difference between a hydrogen ICE from a traditional gasoline engine could include hardened valves and valve seats, stronger connecting rods, non-platinum tipped spark plugs, higher voltage ignition coil, fuel injectors designed for a gas instead of a liquid, larger crankshaft damper, stronger head gasket material, modified (for supercharger) intake manifold, positive pressure supercharger, and a high temperature engine oil. All modifications would amount to about one point five times (1.5) the current cost of a gasoline engine. These hydrogen engines burn fuel in the same manner that gasoline engines do. The power output of a direct injected hydrogen engine vehicle is 20% more than in a gasoline engine vehicle and 42% more than a hydrogen engine vehicle using a carburetor. Hydrogen internal combustion engine cars are different from hydrogen fuel cell cars. The hydrogen internal combustion car is a slightly modified version of the traditional gasoline internal combustion engine car. These hydrogen engines burn fuel in the same manner that gasoline engines do.

Mazda has developed Wankel engines burning hydrogen. The advantage of using ICE (internal combustion engine) like Wankel and piston engines is the cost of retooling for production is much lower. Existing-technology, ICE can still be applied for solving those problems where fuel cells are not a viable solution insofar, for example in cold-weather applications. ICE has been demonstrated based on converting diesel internal combustion engines with direct injection.
