Hydrogen engine

[jeremie73]

In fact when I say air booster it is a booster that works with compressed air, what I thought is to feed it with my father's air compressor. And the booster compresses the hydrogen (the pressure can range from 10 to 2500 bars depending on the model). Some are designed to work with dangerous gases like hydrogen or acetylene.
After that I think it is quite expensive. So I would like to make one.

for a very low flow rate, I have a membrane and water compressor manufacturing chatelot: a water pump like a karcher pushes a rubber membrane and compresses the gas on the other side: it must be very slow to avoid overheating : it takes 10 hours to fill a bottle at 200bar

a refrigerator compressor easily mounts to 15 bar and is perfectly waterproof

Ah that's cool! If it takes time to the limit it's not a big deal. Is it waterproof? Wouldn't you have a drawing to better explain how stp works? Even if he is not very beautiful

I started this compressor to compress oxygen, as if by chance from electrolysis ...

the essential point that I miss to go further is the automatic detection of lack of purity of the gas: I am not a suicide bomber!

Yes, I would like to make a subject on gasification. Nobody almost ever talks about it when the majority of our cars were running on gasifier in 1943 ...

Otherwise, hydrogen is a mess:

30% electricity production efficiency
70% electrolysis efficiency
60% on the heat pump or 30% on the hydrogen MCI
60% on the battery
90% on the electric motor
70% on mechanical transmission

which is done:

6.8% efficiency using hydrogen on a fuel cell

4.4% efficiency using hydrogen on an MCI

so-so

against 14.7% with gasifier ...
Make your choice ;)

Otherwise, the individual vehicle is a dead idea in my opinion, because it consumes 5 times more than a good badly screwed up bus. And there we can still gain corners in emissions, with electric, gasifier, biofuel, biogas ... The mix is ​​sufficiently important

Anyway, electrolysis in the trash!

Ok! Neither do I ! I'll think about that too then! Do you already have a little idea on the subject? I think we should make a system with a lambda probe ... I'll watch that!

I would like to make a subject on the almost total suppression of the individual vehicle if you want;)

For the refrigerator compressor drops, it works essentially for a given fluid, and must be "mixed" with its lubricant.

If you want to move from freon to H2 you would have to find an open seedling, and there I still have doubts

Dsl I'm boring, but in addition to the unfounded of the hydrogen industry, I find that tinkering in his garage on such a dangerous fuel is really too risky ...
But hey if you really want to experience a stroke of grisous, go ahead

Why not!

The efficiency of electrolysis is not top I grant you but I left on this idea so I do not give up!

As for the individual car it may not be a good thing, but I don't think it is a dead idea. Go tell people that tomorrow nobody takes their car but everyone takes the bus or the train ... it will not please everyone

To know if we will continue to satisfy the good of all (in any case Westerners) for a few decades, or to ensure the sustainability of our civilization, that is the question ...

It is interesting to see that the engine of life is to say that our children will live as much as we do, but that now it is rather to have as much fun as we can ... And for our kids, you don't care

I don't think we have much choice anyway

In the era of sobriety that awaits us, I find it hard to understand that we still tolerate a means of transport 5 times more consumer. That is all !

The current system has shown these limits and its failure. It is up to us to draw the consequences and to question ourselves.

the fridge compressor works very well for all kinds of gas: as long as it is not too aggressive for the motor winding

it lubricates very well on its own: problem it sends a little oil into the compressed gas: you need a purifier at the outlet, you have to refill the level before it is dry: normally in the fridge spit oil in the compressed gas is not lost since it is a closed circuit

what I don't understand: if 10 hours for 1m3 of gas seems enough to you: what can it be used for a vehicle? that's a derisory amount!

so hurry up and come and open public transport lines that pass by my house

10 years ago there was a train station less than a km away: it is closed and worse they dismantled the tracks to sell the scrap and sold the land occupied by the tracks ...

but stop the pollution: here we are talking about hydrogen

in other post I also talk about gazogene

for me the hydrogen is of no interest for a vehicle, but the pure oxygen is useful for the welding and so expensive in the trade in small quantity that electrolysing and compressing is more economical

as long as producing the oxygen as compressed as the hydrogen: it works almost as well as acetylene
