British boffins say aircraft could fly on trash, cutting pollution debt by 80%

I think they were talking about Ryanair...

Do not know how it it supposed to cut pollution though, maybe through coin operated toilets?

Re: Who left the gate open?

He had probably read about prof. Lippisch coal powered jet interceptor https://en.wikipedia.org/wiki/Lippisch_P.13a.

However, the way I read his memoirs, prof. Lippisch mainly used this project as a means to keep his students from being sent to the front until Germany collapsed.

Do note that, once they had figured out the problem with the rounded leading edges, this project lead straight to today's delta winged aircraft, so it was not all for naught.

Re: Why not just cut out the middle man?

You say it in jest, but methane has a lot of potential as a fuel, especially for fuel cells.

Re: I was right, then

Generally speaking, unreinforced thermoplastics are not very useful in aerospace outside of non-stressed stuff like glide bearings.

There are alternatives that are sooo much better.

On top of this, expect fdm printed plastics to (in the Z-direction) have 1/3 of the already abysmal tensile capacity of the basic thermoplastic material, and you know for sure that this is not how to make flight-worthy parts.

Now 3d printed metals are interesting, however, I continue to look for good / certifiable data on fatigue.

US task force to look into how military could use generative AI

It is all about imagery

Which is why el Reg should take care to use more AI when generating teaser pictures, rather than using real (stock) photos of RUSSIAN aircraft ( https://regmedia.co.uk/2019/05/14/us_army.jpg) when writing a report about US military forces.

Re: It couldl all have been so very different

"t's a shame that when Medvedev tried to bring Russia in from the cold"

Medvedev never had any power. He was just keeping the chair warm for Putin until he could arrange his permanent precence as head of state.

The West, especially Germany, tried to include Russia into western society. In return they got chemical weapons attacks and civilian airliners shot down. The chickens coming home to roost are Russian, and so far we have been very polite about it.

Quit fiddling about in St. Petersburg and go fertilise a field of sunflowers instead. Your parents may get a Lada.

Don't shoot! DARPA wants to capture future spy balloons in one piece

Re: Prototype High Altitude Recovery Vehicles (HARVEE) exist already.

20mm exploding rounds may result in balloon burst.

I suspect that developing shotgun (dispersing) rounds for the M61A2 20mm Gatling gun to create small leaks and then using aerial capture when the balloon is lower (or just waiting for it to land) may be a spectacular but cost effective solution.

A laser may allow for a more standoff capability, but I am not sure that this is needed.

Aspiration to deploy new UK nuclear reactor every year a 'wish', not a plan

Re: Technical marvel, but it's the economics, stupid

For once, I have nothing to complain about your post :)

May I suggest that you stop bombasting with the repeated use of "unreliables".. It is easier to have a discussion without name-calling.

edit: bombasting, not bimbasting. I can not imagine Bob as a blonde..

Re: Technical marvel, but it's the economics, stupid

Yes, but they have also had to import when the nukes that codejunky insists on as being the only reliable option, could not work due to climate change.

Oh.. and what I was thinking of was last year. Are you saying that it happened this year as well? How can this be?

..And with regards to all end customers electricity price comparisons: Through the unified grid and common market, most of the price differences that you see are political.

Different nations apply different levies and taxes. This is happily being ignored throughout this thread.

Re: Technical marvel, but it's the economics, stupid

"France uses nukes and keeps the lights on for the surrounding countries that use unreliables."

..except for those occasions when the river water is too hot to cool down the unrenukables, and France has to import solar and wind from Germany in order to keep the lights on.

The trick is to have a common grid and diversified power generation. What is really missing right now is storage. This is something we can work on.

Dismissing all renewables as unreliable, and insisting on the expanded use of a power source which can not come online in time, and which, when all aspects is entered into the equation, tends to show up as uneconomical, is something that you may want to think about again.

Personally, I am not against properly conducted nuclear power. However, I am coming to the conclusion that current nuclear technology may not be up to the task on hand.

I do have one or two "pie in the sky" technologies which I hope will surface in time, but for now, I think we will have to create diversified power generation wherever possible.

Bosch goes all-in on hydrogen with €2.5B investment by 2026

Re: Again?

"I have a Proof of Concept that fuel-cell oxidation of hydrocarbons, to electron flow, can reach near thermodynamic theoretical limit. At room temperature. Without the use of heavy stainless steel, in fact with very low cost using no rare metals or elements. It’s a coffee cup stood in front of me, growing mould."

What ARE you trying to say with this sentence?

Re: Again?

Fuel cells have the potential to replace internal combustion as a much more efficient and less polluting way of turning fuels into energy.

If you need to travel far, then there is basically no way around fuel cells.

As things stand, fuel cells capable of using anything but hydrogen still need a lot of development in order to become viable in mobile applications.

On-Board steam reformation of ethanol, methanol or DME suffers from the low gravimetric energy densities of these fuels, and have issues with cell lifespan.

Solid Oxide Fuelcells capable of running on methane, LNG as well as a number of the currently available liquid hydrocarbons struggle around 30% efficiency, and tend to be very heavy (high temperatures tend to require the use of a lot of stainless steel).

Ammonia, as mentioned by others below, does have potential but it comes with it's own issues with regards to handling.

Mature hydrogen fuel cells exist today. the infrastructure for re-fueling has been developed. Storage is an understood science, which still has room for improvement.

F-cells will not beat BEVs for your daily commute anytime soon... But when it comes to vehicles that have to earn money by moving all day, hydrogen fuel cells will be hard to overlook in the coming decades..

747: Creating the World's First Jumbo Jet and Other Adventures from a Life in Aviation -by Joe Sutter, "Father of the 747"

https://www.amazon.com/747-Creating-Worlds-Adventures-Aviation/dp/0060882425

Re: less-noisy maybe but still un-sound

While the Concorde was in development, the US government was also sponsoring the development of supersonic airliners. Boeing SST got the furthest, but I believe thel Lockheed-martin also did substantial work.

The Boeing 747 program was an afterthought, and it very much ran on what was left over in development capacities. The faith in the program was so low, that the aircraft, from day 1, was designed as a freighter. Fate had other plans for the machine.

Also; without the first generation of bypass engines, I do not think that the 747 would have become the sucess that it became.

Bosses face losing 'key' workers after forcing a return to office

This is quite possible.. but if WFH had no effect, then there should be no change between "before WFH" and >"after WFH", and we are observing this effect.

It seems to me that the combination of the stress of the yearlong mortal fear thet Covid was for many, and the multimonth forced "vacation" experienced by many (I hear that people had time to binge-watch netflix and learn to bake sourdough bread) has changed something fundamentally in many.. ..and not for the better.
