Boffins laser print flexible transistors

Re: No mention of how fast these transistors are

"Sure, it doesn't give a solid number in Hz, but you can't really claim there's no mention of how fast they are when it clearly says their performance is just as good as regular transistors."

Wrong again. Mobility is a property that contributes to high speed.

But size and defect density are just as important and if they are printing those transistors they will be huge relative to those on a chip.

So to give the same results their materials properties have to be much better to achieve the same result.

Re: No mention of how fast these transistors are

"Given that they state that their primary application would be in sensors and the like, MHz range would be good enough."

True provided you can avoid using any kind of modern high frequency comms protocol.

People use GHz transmission frequencies because the aerials are much smaller.

Odds on bet slooooow.

The problem with this tech has always been if you use the really low cost methods you end up with really slow transistors. IIRC the record is something like 20Mhz.

OK so that's a pretty sporty PC, back in the mid to late 80's.

Now how do you do WiFi, BlueTooth etc with those sorts of frequency?

Smart meters are a ‘costly mistake’ that'll add BILLIONS to bills

John Smith 19
Gold badge
Unhappy

"I assume this started as an idea with good intentions. "

Why?

AFAIK it's main benefits are a) Eliminate human meter readers (because they still have to be paid, so short range systems won't cut it) b) Re-price your utility prices to consumers by the second c) ability to run fine grained power cuts "demand management"

None of these have any benefit to actual consumers.

A small note on Windmills

While they won't hit the 100 000 RPM+ of an enrichment centrifuge they can still store a fair bit of kinetic energy.

Back in the day the IBM test team were reputed to have found a pattern of start/stops that got a mainframe tape drive (reel to reel) hopping about the floor.

You wouldn't want it to start raining turbine blades (even small ones), would you.

Fix gap in development process

Identify the code pattern of the failure.

That structures is something like 10 layers thick and *very* tough.

Keep in mind by deforming (slightly) on impact it absorbs some of that kinetic energy rather than letting it penetrate.

Such modules can change the whole basis for things like L2 habitats in Lunar orbit, Mars moon exploration or Mars missions in general.

You get a lot more volume for mass than with a solid wall design.

Re: Bulk interception of net traffic is not mass surveillance...

"I have said before that it's no good complaining about mass surveillance if we want to stop mass collection; the government will otherwise simply continue to say they don't do mass surveillance while continuing mass collection."

Re: Pure sophistry

"They can observe selected people using time-honoured techniques: by bugging their phones, their computers and watching their houses. Modern technology means that none of these activities requires a 'spy' to sit in a car across the street for hours on end any more. And more to the point: modern technology means that none of these activities requires a vast, information slurping infrastructure that spans the globe, with everyone's communications being shared amongst the 5 eyes."

True.

But that would require judgement of who is a real threat.

They prefer the view of Comrade Stalin "Better a 100 innocent men to to prison than one guilty man goes free."

Hated smart meters likely to be 'a costly failure' – MPs

Re: Hated smart meters likely to be 'a costly failure'

"All this kit was designed when worries about security were supposedly reserved for the paranoid. If it is ever deployed it will be a hackers' paradise [PDF]- spoofing readings and remotely disconnecting supplies."

And note the first paragraph in the report.

"The European Parliament mandated the replacement of electricity meters with

new ‘smart’ meters by 2022, except in Member States who certify this year that it would be uneconomic. "

Which I think includes Germany.

Runways have other uses

Like delivering the payloads and support equipment to the site.

Near term you're talking about sounding rockets, allowing UK universities to do what German and other Continental universities can do and give their students hands on experience of sending a paylod to space. Sounding rockets could let students do a launch as an end-of-course project.

The other near term option is for Virgin Galactics sub orbital space ride, as possibly XCOR's Lynx.

REL's Skylon is the big one of course.

Euro spacemen clear Ariane 6 for liftoff

John Smith 19
Gold badge

A few notes.

Part of the justification for the mostly-solid A6 was its commonality with the SRB's on the Vega, which is already flying.

Part of the A5 problem is that the upper stage is not relightable. This means that when Ariane try to get 2 sats to launch together they have to close to the same part of the GEO orbit.

While I can sort of understand this for the LH2/LO2 US Astus propellants are hypergolic and ignite on contact.

The other issue is that sat weights have been creeping up and getting a heavy + medium weight pair together is getting harder. However the payload rise is not beyond the bounds of an upgrade starting with the Vehicle Equipment Bay . This thing is in carbon fibre and is less than 1/2 the diameter and no taller than the one on the Saturn V (whose computer weighted about 50Kg and whose gyros weighed another 50Kg without the GN2 to spin them up) yet it weighs the same (the Saturn one was built in Al honeycomb by IBM, not a company known for their light weight structures engineering). The Saturn V Instrument Unit was also designed to carry a 100 tonne Apollo stack on top.

IMHO there is something seriously wrong with this design.

3) Call up the CO of 617 Sqdr and tell him there's a bunch of dams that need demolishing.

And roughly 800miles (rounded down - 4 races per engine) overall before something can be replaced.
