Re: And there was me wondering
Beardy doesn't own it any more.
.. I respect their continuation with the project.
SpaceX will probably have it's Mars rocket in orbit, before this goes into commercial operation.
And I thought they'd come up with a way to fry chips with plasma.

Re: Electric cars are a deadend
Where is all this energy coming from.. power stations
No, because you can produce hydrogen by many ways
The bulk of that energy is in the compression and cooling, which will be electrical in source
Hydrogen is an energy transport medium, not an energy source!
Absolutely, therefore the idea to use whatever source of energy to produce and store hydrogen, something you can do locally without having to be connected to a grid.
The main sources are either hydrocarbons or water, all requiring energy input to create the "fuel", all will need to be compressed and as result of that compression cooled, all requiring energy. I noticed you conveniently ignored that I pointed out that it is incredibly inefficient!
If it is to be off gird, where is your miraculous energy source coming from to create all this supposed magical energy solution?
Re: Electric cars are a deadend
Some have mostly covered this, but not quite:
Hydrogen is an energy transport medium, not an energy source! It takes roughly 35x the amount of energy to create, compress, cool, store and transport the hydrogen as you get out the other end. So as you can see it's an incredibly inefficient one.
Where is all this energy coming from.. power stations, so you think the electricity grid would suffer with batteries it would suffer much more with a hydrogen supply.
Baseload is an issue yes, but Hydrogen is not the solution.
Re: Wheels in the Wings Design Flaw
The SR-71 and it's predecessor the A12 leaked fuel on purpose.
The Airframe was designed for operating at sustained Mach 3+, the resultant heating of the Airframe (even with Titanium) at those velocities resulted in quite an expansion of the Airframe.
So panel gaps were set such that at Mach 3+ the heating would seal the Airframe and subsequently the fuel tanks.
Re: Nearly right ( re:CV rejection)
Negative £50-60k when you add living costs (assumes not at home).
Proxima Centauri, is a Red Dwarf, not a Red Giant.
So it's the first thing to be cut...
Actually the A10 was designed around the Gun, they designed and developed the gun and tried to find a use for it.
I think you mean broadcast system.
Re: Once was a Fan ...
Different regs, in the US it was in breach of the regulations, in Europe it wasn't 'in the spirit' of the regulations.
The US regs specifically state no bypass mechanisms, the EU ones don't.
Re: Hey, really neat!
If there's a way in, you can get in.
Re: Neutron radiation?
Depends on the energy level of the neutrons.
10nm I would guess from the article
Style over substance...
The original is and will always be a classic.
The BMW MINI is a sell out's wet dream
In classic mini circles they are not called Bini Pooper Shit without reason.
This plasma wake disrupts signals, therefore it lasted longer than anticipated, the craft didn't deploy the Chute in time, so once it reached it's desired release altitude it let go (early), the rockets were meant to fire for 30secs, but as the ship was travelling faster than expected it reached 2m early and cut the engines, BOOM!
Shouldn't this have Promo in the title

Re: Why not the Moon?
That and a day on the moon is 28 days, 14 light/14dark.
Lower gravity = bigger medical issues.
Tomorrow's world is now the name of some religious program, guessing the beeb sold the rights to the name.
However your car is capable of doing 140Mph
In your analogy the car would ONLY be capable of XMph, due to the fact the fuel tank is a mile down the road from the car and that's as much fuel pressure the pump can handle.
Ogi, for 99% of vehicles they are still multiple controllers, typically running over a CAN bus.
Mainly due to weight, a controller is usually lighter than that massive bundle of wires and from the OEM's perspective easier to build than adding 200 miles of wiring.
The main priority after getting a vehicle to "work", is making it cheap to assemble.
Re: Checking online might be difficult if...
Actually the cheaper vehicles see more investment in their development as a general rule of thumb.
Simply because they sell more of them, the margin is smaller, but the total profit is higher.
Re: There is no security issue
Prior to the current shambles the NHS was reasonably well funded and generally very effective, albeit not perfect.
From my perspective as I wasn't paying at point of use it was very effective for me.
Now roll in the Tories and their "We have no plans to modify the NHS" and proceed to perform the biggest top down reshuffle since the NHS was founded.
Removing all the political power at the top of the structure.
They also then pushed all the nurses and other essential staff to outsourcing companies, by stating that you cannot have a pay rise.
And subsequently nosed dived the economy, forcing inflation sky high (they needed the push don't you know), with "Austerity(TM)" (i.e. Take from the poor and give to the rich).
Which put additional squeeze on NHS budgets from below and above, with no more money coming in from the top and rising costs from below (private contracts and huge outsourcing wage bill).
They are attempting to do the same with Junior doctors and this so called "7-day contract".
This is all aimed at running the NHS into the ground, to justify pushing it into private hands (flogging it off cheap of course).
Re: 3.5Mb? Floppy?
2.88MB in ED format
But there were also 120MB and 240MB in LS120 and LS240 formats respectively.

@Graham Marsden, Actually the first priority with a roundabout is give way to traffic already on the roundabout.
It's an independent Lock-step micro.
Re: Tesla's progress is amazing
S'ok, give it a couple of years and all cars will be £40k+
"But, what amuses me about these cars is that they are road cars, and road cars are about safety and efficiency, not about high cornering speeds and facebending acceleration off the line (people who test their 0-60 times in public always look like complete dickheads to everyone else)."
Golf car park bragging rights...
Re: Units, not numbers
One potential solution, but you need to add the capacitors and they are still big and heavy. Then they need to be integrated into the system, more wiring, more complexity, more weight, more cost.
A processor that may be able to run AUTOSAR.
Might not be able to do much else, but what the hell, the Manager has their AUTOSAR box checked.
"Flight 20 wasn't the first rocket to successfully reach space and return, since Jeff Bezos' New Shepard rocket managed that a month before"
Nope... SpaceShipOne did it first. (From a non-governmental perspective)
Some may argue the Space Shuttle did it first.
Bezos achieved the first Earth bound powered landing, which is a different thing.
Think we need to make the turd polish more toxic
Re: Sorry how much?!
"Obviously it's more than just helium, but what the hell has cost $100 million?"
Engineering cost + nice fat pay off for military contractor.
Ford usually spend around $2bn developing a new generation Transit van.
VW spend ~$13Bn/year on R&D.
Boeing spent $32bn on the Dreamliner.
So $100m for a prototype is cheap TBH.
Custom malware to put backdoors in their system, hunt for the victim/payments db, refund all the victims and corrupt the DB.
Re: "required to make disclosures of their engine software"
At which point all the Tier 1 suppliers will start legal action.
About 10 years too late...
Re: Not the first though..
Also Virgin have been offering pure BB with no phone line for quite some time.
Power draw indeed
Most LASERs are 10-20% efficient, so your 100kW unit is going to need IRO a 500kW to 1MW power supply to run it, not mentioning chemicals etc. Depending on the type.
Re: Just so long as jealous yanks....
They are already in talks with US aircraft manufacturers for supplying pre-coolers.
No the air is slowed to subsonic speeds, that is why there a inlet cones on the front of the engine.
Slowing the air causes compression and resultant heat. Hence the need for the pre-cooler.
There is a compressor stage which feeds the rocket engine with air.
It does not compress and cool to liquid, for the icing problem.
HOTOL is a LACE engine Liquid Air Cycle Engine, this is a VACE Vapour Air Cycle Engine.
It is not a Jet in the traditional sense, that is just poor understanding on the part of the reporter.
It's an air fed rocket engine. They just happen to use a turbine to put the air into a format the rocket can use.
It's all waiting for the folding screens, until then nothing much will change.
There is a political issue as well, the extreme greenies want a much greater reduction in emissions (for obvious reasons) than can realistically be achieved with the technology available at a cost effective rate.
Automotive OEMs are driven by their markets and cost.
The purchasers (in general) want a fast, cheap car, that doesn't break down and does 100mpg.
Most governments are being pushed on AGW, which is pushed on the OEMs, who want the cheapest solution that appeases the regulators and their market.
Re: I have yet to figure out why people are afraid that an AI would want to kill off humanity
1. Radiation out in space is much more damaging to electronics than under this nice atmosphere and magnetosphere.
2. There are a lot more computers on Earth for the 'AI' to infect and make use of, greater power, from the perspective of the AI.
Some of it yes.
Re: What's the current estimate of the computing power of the human brain?
Current estimates are 100PFlop equivalent (brain is mostly analogue with digital elements), and 20-40w.
So have they actually made a word diff tool that actually works?
