I am, and yes they had fuel cells for that.
As for the patent - this is shabby in the extreme. Many USA drug patents have had long lists of compounds which were only synthesised on paper but generally not reputable companies.
Even if I'd not seen examples of other mobile devices powered by fuel cells such as laptops ( and 12v supplies for motorhomes plus the Apollo capsule example this would be obvious in the patent sense anyway.
If Apple care to patent a specific design with some demonstrable advantage then that is patentable. But to just claim fuel cell power for mobile devices..........
It could have just been a proton with a very-close-to-light velocity.
Even in the LHC the protons have ~1 micro J energy. They wouldn't have to go much faster to reach 50 J. They would, of course, have had to have been accelerated by a mighty powerful mechanism but the universe is likely to have quite a few of those.
Given that vehicles heights vary up to and beyond 4m a car would have to have enormous mechanism to reach the wires which would probably have to be 5m+ above the road.
As mentioned above overtaking would be impossible with multi-lane roads thus reduced to multiple single tracks moving at the speed of the slowest vehicle.
So either the range is conservative or the something is wrong
I can't answer that except with a diesel example
My 2.0L Touran averages about 55mpg but climbing the 27km from Visp in the Rhone valley to Saas-Fee ( diff in altitude ~1200m )it does ~28mpg. Coming back down it's more like 120mpg. Now, of course, you can't just average the mpg but I calculate that it's about 45mpg overall.
With regenerative braking an electric car might well get quite a lot closer to it's flat value
It's got a 24KWhr battery so if it was flat it would be ~~ £3 for a full charge unless it's done off-peak
I take your point,of course, but I don't see the symmetry if only one has "dangly bits"
You have made the error of not noticing it was a JOKE !
They really ought to discourage PowerPoint usage in science degree courses.
Fixed it for you !
Is that a cousin of the "Somebody-Else's-Problem" field ?
I agree entirely with that.
I worked with an extremely intelligent chemist who could think & rationalize well outside his area of expertize but he thought computers were binary - it never crossed his mind that you could parallel the binary logic and make 8-bit,32-bit etc,. systems.He assumed it was ALL serial.
I believe that GPS based altimeter readings show the SW of England rising and falling each tide by a measurable amount due to the continental crust being pushed down by the increased weight of the sea.
CO2 absorbs outbound infra-red radiation thus heating the atmosphere more than if it were not there. It's totally irrelevant whether this occurs at .003% or 1% - it depends on the gas. In the case of CO2 0.003% is significant.
However HEAT != temperature. Different materials have different specific heats and worse than that ice/water has a large energy involved in it's phase transition ( ice at 0C + lots of heat > water at 0C )
As I've pointed out before rising CO2 levels should cause retention of more HEAT - simple physics
but the relationship between heat and temperature on a planetary scale is likely complex - a very simple example is that you can put lots of heat into ice at 0C and it will stay at 0C until all the ice has melted.
Whilst I agree that it's difficult I do know of 2 people that have had 3 hip replacements. Takes quite a bit of doing and can involve bone-grafts
Good question. It is controlled in normal bone repair but quite how ...
Even more astonishingly normal bone is constantly remodelled by osteoclast cells that attach to the bone, dissolve away the mineral part, enzymatically degrade the protein matrix and then the 'hole' is refilled with fresh protein by osteoblast cells . The protein matrix acts as a scaffold for calcium ions in the blood to deposit and remineralize the bone.
The process may stop naturally as all the protein is covered calcium but I'm not sure about that.
Pity it's just a fictional means of travel !
but UK Parliament is also available as wmv format which can be used by Linux browser plug-ins
Strange - it seems to be from here.
Just harangued http://www.parliamentlive.tv
"Watch" that space
"giant mutant" before space goat
Not for the MoD I'm sure
"The price is about nine times what one might expect" - I'd expect not to be able to buy such a small one anymore
Do you mean 128GB ?
Just use a rotary drier.
( When it's not being used it could make the craft look more like a 'real' spaceship which everyone knows bristles with that kind of antenna)
I think that was Motorola 6800 or 6809 CPUs - I can't remember
this is a laserjet issue I understand
That'd be the fuser used to melt toner onto the media
I've still got a chart of the (gigantic) number of op-codes on my study wall. Spent a long time writing 6809 assembler including a floppy disk driver & formatter for my home-brew Forth system
Simpler days !
Using a sub-set of 6809 op-codes you could write true position-independent code and I think BRA was the JMP relative version of JMP
6809 - yes !
Less and less - they use an enormous amount of water unless a pump recirculates in a closed system.
A lab water pump will get to ~~15mm Hg absolute .
They self-discharge far too quickly
No you were wrong about the arsenic bit.
The reason why carbon seems so important is that it's got a lot of useful properties all in the one element
It can bond with 2,3 or 4 other atoms either with single. double, aromatic or triple bonds. It's reactivity can be altered relatively easily to make or break bonds. Long carbon chains can be relatively stable. Other elements don't have all or most of these properties. I could go on but it would end-up being a text-book in organic chemistry.
on my aging laptop and got a 1GB file in ~15 secs.
How fast can you sidle ?
Shouldn't that be -
"Microsoft is so much better off with the world being forced to have Windows as standard" ?
Ha, ha, ha ......
is Pu 238 which is not fissile but generates a high decay heat
Every time anyone uses a GPS they are getting data that has been adjusted for the effect of spacetime being distorted by Earth's mass.
That I've read in a long time.
No wonder you're an AC
Worst than that.
The two proton beams at the LHC each almost travel at c. To an observer outside the beam it appears that the closing speed is ~2c, but to an observer traveling with a proton the closing speed will always appear to be <c
It's one of the reasons relativity always appears so bizarre to non-relativitists Worth looking up 4-velocity.
That's not General Relativity - it's almost the opposite
The presence of matter & energy curves spacetime - the effect of moving through 'bent' spacetime is *perceived* as a fictitious force called gravity.
Oh, good grief !!
What they will be doing first is to try and duplicate the finding, preferably somewhere else with different equipment
Only on the basis of good hard experimental results that disagree with SR ( which has HUGE existing experimental support ) will there be a need for theorists to get involved.
Anything else is pure speculation for speculation's sake
So was it or was it not regenerated ~5200 years ago ?
Must check the house insurance.
Used extensively in the fine chemical industry - it's a high-boiling point dipolar aprotic solvent meaning it has a high dipole that helps to solubilize materials but isn't capable of ionizing under 'reasonable' conditions.
Reading the data sheet is a bit like looking up your symptoms in a medical dictionary - scary
With correct handling, ventilation and recycling it's no problem. Doesn't mean that you should be using it in a 'normal' inkjet printer though
a pencil !
I don't need to tell you anything - you already seem to know it all
As for Are they moviing faster than C?
Or are they traveling on a shorter path?
Until the experiment has been repeated by independent labs using diff.equipment then there isn't anything to explain.
As several other people have pointed out your understanding of GR's explanation for gravity is deeply flawed.
they'll have already read HHGG and will turn up expecting Bournemouth ( or was it Eastbourne ?) to be 'one of the most exciting places in the galaxy'
