Inventors: Feast your eyes on fuel cell tech that'll power up Internet of Thingies

When I saw "fuel cells" I *hoped* someone might have gone with sugars.

Sugars are everywhere in nature, they don't need fermentation and there are plants specifically bred to optimize their production.

Maybe one day.

"I can't understand how anyone can support data which only exists because people are compelled by law (under threat of punishment by the state) to provide data to government, being used by commercial companies."

Because they see the "Easy money" aspect and not the extortion (by the State) that makes it possible.

Re: Calling Elon? He's busy fighting ULA

"Elon Musk held a press conference on Friday 25th April where he accused (or pointed out, depending on how you look at it) ULA of ridiculously overcharging the DOD for their launches and how odd it was that the more-expensive service provider got the lions share of the next wave of launches. Expect fur to (gradually) fly over the next few month"

That was part of his anger. What really p**sed him off was the Air Force said Spacex could bid on EELV launches, which to that point they bought one at a time. Spacex set to work to demonstrate they are capable of launching USAF payloads below a certain mass and delta V requirement.

Then the USAF turned around and said they'd done a 36 core block buy from ULA and they were cutting the launches they think Spacex can do by 1/2.

The Secretary of the Air Force's behavior in this shall we say seemed "anomalous"?

Is the *idea* of "outsourcing" the best scam MBA types ever thought up?

It must be in the top 10, right up there with the idea of "Collateralized Certificates of Deposit" where banks convinced suckers depositors that

9 parts s**t + 1 part Gold --> 10 parts Gold.

instead of 9 parts s**t.

I wonder if some (probably MBA) type will make their fortune by developing a proof that outsourcing can never deliver the scale of savings expected without grossly unrealistic starting assumptions (and what those assumptions are).

Probably not.

They'd be killed by all the other MBA types to protect the golden goose.

Re: What are we going to do when the super-solar flare arrives?

"The earth is extremely well protected against many kinds of radiation, including solar flares. The only way for a solar flare to do damage is to capture the energy with a big antenna array. Stringing wires up on poles spanning long distances will do nicely. But it's not like everything connected to those wires will instantly explode. The rise times are far slower than a lightening strike, and most equipment survives a nearby strike."

That's very comforting.

Small point.

How many satellites will be cooked by this? BTW GPS sats are just under the inner Van Allan radiation built so it's fair to say they are on the outer fringes of effective magnetic shielding for the Earth.

Algorithm ramps up genetic computation

John Smith 19 Gold badge
Unhappy

It's a classic string pattern matching problem

The trouble is that most algorithms that do that like big alphabets so a failure can skip the pattern string further along the main string.

But DNA is a 4 character alphabet unless you can assume that the pattern and main string will only align every 3 positions (IE a codon), giving you a 64 set alphabet. But I'm not sure if that assumption is always reliable as it's been a while since I read on this.

DNA is fascinating in that some amino acids have several codes. They are therefor "robust" in transcription errors (mutations), while others are fragile and any mistake knocks out a different amino acid.

The question is did this code assignment develop early and never change or has it also evolved? Likewise does the "fragility" of certain amino acids transcription have some sysetmatic effect on the compounds they form?

Sadly that's all above my pay grade.

Re: Is this a joke?

"Why not lock us all up straight away just in case?"

To these people the answer is not "Because that would be a police state where due process and the right of trial by jury has gone down the gurgler."

It is "Because we don't have enough space (yet)."

But you're quite right surveillance without warrant --> imprisonment without trial --> world without crime.

Clearly the law needs to be changed alright.

To mandate the destruction of the metadata as well.

And you'd think the word that the EU Data Retention Directive is being binned had not reached the antipodes.

Let's be clear. This has (as usual) f**k all to do with "fighting crime" and is the usual data fetishist obsession with knowing (and storing) more data about everybody, because they can.

"Fighting crime" is just the excuse de jour.

Theoretically a hardware RNG is best.

"By the way, those bad boys use 386SX-16s with a separate math coprocessor. Zoom!"

AFAIK the ISS MDM's are split into "tiers."

Only the Tier 1 MDM's have processors.

The rest collect (multiplex) and distribute (demultiplex) data from the network, 1553b on the Shuttle, Ethernet (I think) on the ISS. The clue is in the name. It's just that NASA's ideas on architecture have changed over time and things have become "smart."

"And for that matter, why isn't it being used for rail vehicles? I can remember "Booster Electric" locos in the 1950s which used big flywheels to store energy. They were later converted to electro-diesels."

Well there is at least one UK train line that uses a small LNG car engine to pump energy into a flywheel. The flywheel does the heavy lifting.

It's been running for years IIRC somewhere in the Midlands.

Re: @ John Smith 19

""Perhaps so yet in other countries with other religions some how the religion doesn't seem to get in the way of a technical education."

I think you conflate hatred of the West with a hatred of technology. If I were brutally honest I'd say the Palestinian / Israeli conflict is a land war that persists due to the massive funding of exterior parties for their own reasons. Large personal fortunes (either made or being spent) and efficient lobbying (to continue US involvement on the "right" side) make this a very difficult problem to resolve. Whenever a bad situation never gets any better follow the money.

Antisemitism has very little to do with this issue.

The effective theft of $13 T from the Iraqi economy might have upset a few Iraqis as well. "My enemies enemy is my friend" is a principal the US has long followed (like the CIA's support of Bin Laden back in the day. What could possibly go wrong with that plan?)

Hatred of the West didn't stop the Afghans down loading unencrypted drone video or building cost effective IED's.

"The reason the space shuttle cost so much was because it was operationally crippled by requirements imposed on it by the US military. They wanted cross-range capability and cargo return abilities that the shuttle never actually ended up using."

Getting closer.

The real question of course is what were the impact velocities, roll rate and angle at sea level.

"Roll rate" is very important because it was the stage spinning on it's long axis that was causing the fuel to centrifuge away from the engine inlets, starving them of propellant on the last flight.

The other point is if the stage was at M1.1 at 8.5Km what was its trend?

If it was slowing down IE Drag > gravity force that's a good thing. Drag < gravity force --> stage accelerating. Not so good.

What really happens at this stage is collecting a rich crop of data, which seems to have been 100% successful.

Re: I thought Space-X were supposed to be making space flight cheaper...

"Joking apart, it does seem somewhat odd. When SpaceX first got going their aim seemed to be to have a very cheap way of manufacturing rockets, meaning that the rockets themselves could be disposable yet profitable. That was even reflected in their engine design."

No. The F1 was very much a "starter" vehicle to gain experience.

AFAIK Musk has always known reusability was the way to go and that means regenerative cooling.

"I'd rather have a hydrogen leak than some of the other propellants like hydrazine. At least it's effectively non-toxic (with a lower toxicity than oxygen) and disperses quickly, leak detection is probably a pain in the arse though."

True, although GHe is not actually a propellant.

"Are SpaceX using LHe to cool the LO2 tanks?"

No. Helium liquifies around 4K, 1/5 that of Hydrogen. Gaseous Helium is mostly used for tank pressurization (although O2 tanks can be pressurized by boiling some in a heat exchanger on the engine) and providing the driving force for activating valves.

Re: Helium is *very* hard to seal systems against

"For me, that is the reason why hydrogen powered cars are perhaps a bit of a dead end. But maybe the problem can be solved somehow - we will see."

Looking at some of the diagrams it looks like

They make up graded alloy strips where one or more of the elements varies along the length.

The strip is then laid on top of what looks like a plate with holes in it. At this point I'd guess they put the whole lot in a furnace and connect it to a high pressure supply.

They then try to blow bubbles with the metal.

Biggest bubble seems to win.

BTW I suspect the problem with quantum chemical tests is 1 simulation will take hours and the effect is (I suspect) non linear, so extrapolation does not work.
