Microsoft runs a data centre on hydrogen for 48 whole hours, reckons it could kick hydrocarbon habit by 2030

Re: Hydrogen is a solution and its own worst enemy

Good point on the PM2.5.

We've dealt with one emission problem with catalytic converters, could some form of filtering, perhaps a vortex filter instead of a mesh or maybe an electrostatic method to separate out the dust could be developed to ameliorate the problem.

Shouldn't be a huge problem on fixed installations, might be trickier on mobile ones like cars.

Re: Hydrogen is a solution and its own worst enemy

You missed out the energy requirements in compressing Hydrogen for storage and the massive costs that would be entailed in rolling out Hydrogen distribution infrastructure.

Biofuels are a far superior "green" fuel, no storage problems, can use existing distribution infrastructure and as second generation biofuels use agricultural waste instead of primary food production the the valid argument that biofuels displace food production no longer apply.

I was going to post a snarcy comment along the lines of so they've hooked a fax to an acoustic coupler and invented Radio-Fax but thought I should perhaps do 5 or 6 seconds of research first.

It seems from the 1930's to 1970's there was a system called "Radio-Fax" which was indeed the precursor of SSTV.

"Government pledge"


The current government has failed to keep a single promise or pledge.

It's the tried and tested "Tory way", make a big announcement and get lots of favourable press from their tame poodles at the Mail, Telegraph, Sun etc, Blow a few million to a tame "consultant" who will tell them exactly what they wanted to hear and then do absolutely nothing.

Anybody remember "The Great Nothern Forest"? £13m to a consultant and then, fuck all.

Just like Johnson was held to account for wasting over £1billion on failed vanity projects when he was the mayor of London.

Re: Worst American president ever

The USA has solved the deaths problem with a system that doesn't count the all deaths accurately

That'll only work for a little while, the benchmark is comparing the average total death rate for the preceding few years with the current total death rate, the difference can be attributed to C-19 and related issues.

Very difficult to conceal the total number of deaths even if you do fudge the cause of death.

Re: "ADT failed to monitor consumers’ accounts"

No, all it takes is ADT to design a system where abuse is both possible and able to remain undetected.

Yes you are going to get "bad players" but surely we all know that, you know that, I know that, ADT know that so it is inexcusable for them not to have taken that into account when designing their systems.

But they are wholly responsible for allowing it to happen in the first place and not having protocols to prevent and detect abuse of their system, for that alone they should burn.

Re: Wow

Hydro-electric is a steam engine powered by the Sun

Nicely put, an excellent analogy - wish I thought of it first.

DJO Silver badge

Re: Wow

Tidal lagoon hydro-electricity is using gravity.

In the same way as hydroelectric does. It uses gravity as a tool to get at the potential energy it is not directly tapping gravity which is what the OP was suggesting.

Gravity is a function of mass, it cannot be "consumed". As long as the mass is constant the gravitational attraction is constant so it cannot be an energy source.

DJO Silver badge

Re: Wow

If we ever want unlimited free energy, we really need to harness gravity

No, it doesn't work like that. The only way to harness gravity is things like Hydroelectric where gravity is used to get the potential energy out.

Getting energy directly from gravity is the same as getting energy from a stationary permanent magnet; perpetual motion and the universe does not allow that.

However (in physics there's always a "however") should we ever work out how to do anti-gravity then all bets are off.

Re: Copper foil

Cupronickel, bronze, and brass surfaces as bactericides can be almost as effective as copper

True but there's also the frequency of contact with coinage to consider. 100 years ago it was cash or nothing, maybe a cheque if you were posh. Now with electronic transfers, credit & debit cards, pay pal and other similar schemes people can go for days without ever touching a coin.

DJO Silver badge

Re: Copper foil

Wondering about that.

Both silver and copper have anti-bacterial and anti-viral properties, back in the days of Spanish flu coinage was still copper & silver so most people would be handling one or both metals daily.

Now with cupro-nickel instead of silver and plated steel instead of copper people don't receive that benefit. Also many hospitals used to have copper door knobs which helped in restricting the spread of infections - it was years before they worked out why modern hospitals with automatic doors or shiny chrome plated door knobs had a slightly higher infection rate to older hospitals.

Re: Still not convinced

Hydrogen is probably the worst possible fuel imaginable, apart from containment issues which are a nightmare you have to get the damn stuff from somewhere, yes it's the most abundant element in the universe but here on the Earth almost all of it is chemically bound to other elements.

Currently there are 2 industrial scale ways to make it:

Electrolysis, really inefficient and the power has to come from somewhere.

Catalytic breakdown of natural gas, produces just as much CO2 as burning the gas and needs a lot of energy because the reaction (with super-heated steam) needs to run hot.

OK so you've got your gas made, you now need to compress it and guess what, that uses a shit load of energy.

There is research ongoing for biological production of Hydrogen but scaling that up will be tricky.

DJO Silver badge

Still not convinced

I don't think electric cars are the future of transportation, they have their place but it's not at the top of the sales chart.

Biofuel would seem a better but, more specifically the new second generation biofuels which use agricultural waste instead of food as feedstock like the first generation (mis)used.

As I see it a big obstacle to wide scale adoption of electric cars is that a lot, possibly the majority, of homes in the UK do not have parking close enough to the house for a safe power lead and we really don't have the generating capacity for really widespread adoption. Also biofuels can use the existing petrol & diesel infrastructure which would save billions in costs.

Also as soon as electric cars make a noticeable dent in the duty the exchequer collects on fuel, they will introduce a mileage tax or some similar way to recoup the lost income which will remove a major incentive driving the sales of electric cars.

"I'm Graphics Artist. Not a Chemist!"


If you have been told all this by a chemist, he's trolling you. 250K is the current limit for superconductors. An improvement to say 275K would be massive news all over the physics world.

One at 453K would be the biggest science news for decades. It's not been news, not a tiny hint anywhere, not even a discredited rumour, nothing, nowt, not a peep - except for you.

Re: Still a problem though

Hi, me again..

It's obvious you have no idea of what you are going on about because of (at least) 2 obvious and glaring mistakes:

"180 Degrees Celcius or 453.15 Degrees Kelvin"

You cannot introduce accuracy on unit conversion, you should say "453 Kelvin"

Nobody ever would say "Degrees Kelvin", it is just "Kelvin" - It's an SI unit, there is no room for personalisation.

Yttrium Copper Garnet Gallium Nitroxide Ceramic

Nitroxides are cyclic radicals which are completely unsuitable for ceramics, they would break down long before the ceramic was formed.

Garnet isn't even a chemical, it's a group of gemstones, the most common ones are:

Almandine: Fe3Al2(SiO4)3

Pyrope: Mg3Al2(SiO4)3

Spessartine: Mn3Al2(SiO4)3

Th only common bit is the silicate part, silicates are not among the chemicals known to superconduct at any temperature, much the opposite in fact, silicates are insulators.

DJO Silver badge

Re: Still a problem though

Sorry but you are wrong.

Anybody with a superconductor that works up to 180C would have a fleet of gold Ferraris as a superconductor working nearly boiling point would solve a million problems from energy storage and transmission to efficient motors, levitating trains and, well, everything.

A 180C superconductor would be world breaking news, Nobel prizes guaranteed. Such news has not broken therefore it didn't happen.

TBH a superconductor at 180K is pretty damn impressive and that's where the work is now.
