Instead of having pipes going into the house, a lorry pulls
up outside and brings in heavily insulated containers with
blocks of hydrogen and oxygen ice inside them in the
appropriate proportions. You put these in a heavily
protected and evacuated chamber and pile them up
adjacent to each
other, then apply a spark. There is an
explosion, providing energy to the house, and the chamber
fills with steam which condenses to form water, which you
can then use for heating, washing, flushing the toilet,
cooking and drinking. When you're done, you store the
water, urine and the like in a tank outside the house which
is emptied by the company which provided the hydrogen
and oxygen ice into a water tanker lorry, which takes it
away, distills it, separates it into its component elements
and freezes them into blocks, which are then delivered
back to you. Obviously you pay for all this.

Why not pipe the elements? |
|
| |
Let's assume that you start small on this, with a cube
of hydrogen 10cm on a side. This will have a weight
of about 80 grams. |
|
| |
To go with it, you will need about 700g of solid
oxygen, which will be about 8cm on a side. |
|
| |
When these react, they will liberate about 100MJ of
energy, and they'll give you two large glasses of
water. |
|
| |
No, one large volume of steam, and a violent explosion. [+]. |
|
| |
Ideal for a "hydrogen economy". Electrolyse water with nuclear or
renewable energy. Distribute the hydrogen to consumers. It can be
used in CHP units, burnt as heating fuel, fed into fuel cells, or used to
fill pretty coloured balloons. |
|
| |
//one large volume of steam, and a violent
explosion.// |
|
| |
I believe the chamber is intended to act as a pressure
vessel. Hence, ultimately, you'll have water. |
|
| |
Seems fairly pointless, My Dear Sherlock. |
|
| |
Perhaps every home should have pipes for each element. Then by selecting an appropriate combination of nozzles, you could create whatever substance you wished for, in an explosion. |
|
| |
Forget the delivery trucks. Can't I just pull hydrogen and oxygen out of the air to make my own water? |
|
| |
Oxygen, yes. Hydrogen, no. |
|
| |
// you could create whatever substance you wished for, in an
explosion. // |
|
| |
What could possibly go wrong ? |
|
| |
Let us know how that works out for you, |
|
| |
I want delivery. Big refrigerated lorries full of blocks of exotic
ice. They could do it with the gas supply too. It does also
store energy and move it around, you realise? |
|
| |
I would like my water delivered as elements. But not
oxygen and hydrogen. |
|
| |
Hydrogen ice? Even Hydrogen liquid would be unlikely. It
would be shipped as a highly pressurised gas. That's why
you don't see many Hydrogen fuelled vehicles, because
Hydrogen is a pain in the arse to compact, except by
perhaps combining it with something else, like Oxygen. |
|
| |
I'm just very attached to the solidity and coldness. I choose to
have my water delivered as frozen elemental gases not
because it is easy but because it is hard. |
|
| |
//one large volume of steam, and a violent explosion.// As
long as the reactants are solid, I would think it would be
quite difficult to generate much of an explosion. |
|
| |
tsk, I waited around all day, nipped out for a pint of milk, get
back and there's a card on the mat saying I should wait 24
hours and collect from the post office. |
|
| |
explosions and silliness [+] |
|
| |
It should be possible, with suitable fusion technology,
to just deliver the hydrogen. |
|
| |
Add fission to save on deliveries. |
|
| |
Depends if they ship by weight or volume. |
|
| |
This seems a wee bit complicated. I may not be able to do
this. |
|
| |
Can I have mine with extra French Carbon Dioxide, please?
{I'll taste the difference if it's English!} |
|
| |
// French Carbon Dioxide // |
|
| |
Certainly, if you are desirous of a lingering oudour of Gauloise,
garlic, defective drains, institutionalise corruption, and endemic
cowardice … |
|
| |
English Carbon Dioxide has the unmistakeable odour of
upstanding righteousness and courage, inedible school dinners,
honesty, stiff upper lips, rum, sodomy and the lash … * |
|
| |
* Check the box for "Public School" for the inedible school
dinners
and, err, the other options. |
|
| |
Hi [Dub], want a drink. Very long time no see. Yay. Hi. |
|
| |
You could provide carbon dioxide by just adding diamonds to
the oxygen. |
|
| |
Hiya, [blissy] :P) Yes, please. {Offers the wrong glass.}
French diamonds, right? |
|
| |
What's not to like about this? |
|
| |
Apart for the 118 pipes that would be needed. |
|
| |
And how could you be sure the utility company is really putting in hahnium at their end? They could be putting any old crap like Lawrencium in there and just saying "Oh, it must have decayed on the way" |
|
| |
If you're just going to stick to boring old hydrogen and oxygen, you could add entertainment value by running them through a pipe organ afore the combustion |
|
| |
When I read this idea and the annos I thought; couldn't hydrogen be delivered in solid form through insulated vacuum pipes and then, as it sublimates, be burnt in the presence of atmospheric oxygen to produce water as a by-product of combustion? |
|
| |
I can't find any information about the burn rates of solid hydrogen... in fact there seems to be an awful lot of things not known about solid hydrogen. |
|
| |
I don't understand, is solid hydrogen not an ice like solid carbon dioxide? |
|
| |
Supposedly piping gaseous hydrogen is pretty tricky.
Not sure where I read that, but there was some
article about hydrogen powered cars talking about
how the seemingly simple idea of having a
compressed hydrogen tank with tubes to the car like
a standard gas station is pretty impractical at this
point. |
|
| |
Not sure: A) where I read that B) if it's true C) if I
dreamt it. If it was a dream I need to start having
more interesting dreams. |
|
| |
"Not sure: A) where I read that B) if it's true C) if I dreamt it. If it was a dream I need to start having more interesting dreams." |

I'd like to bun that anno. |
|
| |
I've long found it a little puzzling that except for mercury,
everything whose triple point is colder than that of water
seems to be an ice. Some things hotter than ice also seem to
be ices, e.g. quartz, but it just seems a bit of a coincidence. I
suppose it's because water is peculiar due to the polar thing. |
|
| |
Under enough pressure Hydrogen turns into a super conductive liquid metal even at room temperature? What?!! |
|
| |
How friggin awesome is that? |
|
| |
I can see it becoming reality that people will use their fuel
cell cars to generate electricity for their home during
network peak hours. But keep in mind that it will always be
less efficient than a big optimized electricity plant. |
|
| |
This is the best idea I ever heard (in this moment)... OK, I'm over it now. Well Done, [nineteenthly], zee beeg bun I have for you [+]. (Don't bake it all in one place) |
|
| |
// How friggin awesome is that? // |
|
| |
You should see some of the party tricks you can do with the stuff,
particularly liquid metallic Deuterium ... oh, how we laughed. |
|
| |
Perhaps, instead of working on solid adsorbents for fuel-cell vehicle tanks, they should try liquids - run it into your house (or car), heat to a certain temperature to release the H2, send the empty working fluid back. |
|
| |
//There is an explosion, providing energy to the house [...]// |
|
| |
Guy Fawkes: "I was just providing energy to the House!" |
|
| |
That reminds me, what are the theoretical objections to
magnetically decelerating shrapnel, and then using the recovered
energy to recharge your phone? |
|
| |
//I'm just very attached to the solidity and coldness. I choose to have my water delivered as frozen elemental gases not because it is easy but because it is hard.// |
|
| |
Melting temperature of hydrogen : -259.16 °C |
|
| |
It's doable, it's just not easy.
Absolute zero is only around -273 °C.
Interestingly, the boiling point is -252.879 °C, so it's only liquid for 6.3 degrees at standard pressure. |
|
| |
How much energy is there? Using Max's value of 100MJ, that would be enough to boil - that is, raise the temperature of liquid water from 20 °C to 100 °C : (100,000,000/ (80*4.2*1000))= about 300 litres of water. |
|
| |
// what are the theoretical objections to magnetically decelerating shrapnel, // |
|
| |
You would need a very large linear motor with a very intense field. It would also need to be correctly aligned to the path of the projectiles to be effective.
You would need superconducting magnets, refrigeration plant, and a suitable suppy of electrical energy. The equipment will not be portable in any meaningful sense. |
|
| |
// and then using the recovered energy to recharge your phone? // |
|
| |
There are probably more cost-effective ways of doing that, like using a tiny steam engine made of solid platinum, fuelled by burning cut diamonds and using vintage burgundy as the working fluid. |
|
| |
Yes, I think it would form as superheated steam, but that's a
plus because the heat from that can then be used to warm
the house or maybe run a steam turbine. |
|
| |
And, well, it was me who thought of the rose absolute
powered internal combustion engine so I'm at peace with
financially expensive energy generation. |
|
| |
I think this is a good opportunity for "Cut-me-own-throat" Dibler to
supply a DIY kit. |
|
| |
Hand crafted by Monks, this device gives you access to Hygrogen
and Oxegene in large quantities, and it only weighs a few Ankh
Morpork bacon and sausage sandwiches.
Not only that, the Hygrogen and Oxegene are copiously available after
a good testing of the local ale houses.
One end of the string is tied to a bucket full of piss..er water...and the
other end is attached to a kite. A thunderstorm makes it work even
better, or I'll cut me own throat. Stand well back. |
|
| |
//fuelled by burning cut diamonds // |
|
| |
Ah, now that would be the Mark II Lavoisier Engine (see link). I'd
heard you had a few of those on your hands after Buchanan
Towers sent theirs back because it didn't match the curtains of
the south-west groyne. But that might just be a rumour put out by
a rival in this brutally competitive business. |
|
| |
Of course, what Lavoisier needed was a device to magnetically
decelerate the falling blade of a guillotine, to provide just enough
juice to send a text to his friend Benjamin Franklin. A tricoteuse
selfie would be attached. |
|
| |
// But that might just be a rumour // |
|
| |
We had just one returned as "faulty". A better description would be "damaged by gross misuse" - it wasn't eligible for repair under warranty ... |
|
| |
// Dibler // Sp. "Dibbler" |
|
| |
Could I get away with it if I said I used the American
spelling? |
|
| |
You could get away with "al-D'blah", or "Disembowel-myself -honorably..." but not "Dibler". |
|
| |
I've just realised this is the opposite of Thales' idea of delivering
the element supply as water. |
|
| |
That's pretty warped.
...and more than a little bit weft. |
