Many uses for a lighthouse

You'd think so, but actually lighthouses are just general navigation beacons.

You get big powerful ones that you can spot from far away as you approach the coast from the sea, these tell you basically which part of the coast you're approaching. Then you might get a smaller lighthouse to signal the clear water channel to approach a port. Any dangers they warn about are basically irrelevant to a boat of less than a ton.

Also many lighthouses don't illuminate 360 degrees. If only because then the local villagers can't sleep, but also to only cover a particular danger or channel. So even if it was working its feasible that it wasn't identifiable in the fog.

Reverse engineering is not forbidden by law. Your favorite breakfast cereal can be reverse engineered by your local discount supermarket. So you can look at an existing product, write down the spec of the value it provides, pass the spec to a team that will produce a lookalike, and iterate over the process untill you get a marketable product.

The law says that you can't copy. So the team isn't supposed to see the existing product. That's ensured via copyright protection. The law also provides patent protection, but no only for reverse engineered products.

I was told that 20% of products put to market fail because "they were only coping existing products", and I thought "that's excellent, lets do that!".

The process, shown in Figure 4, involves first coating the part surface with a sacrificial ablative layer (typically paint or tape). Water is then flowed over the part surface and a high-energy laser (1-10 GW/cm2)1 is directed at the target region. A laser pulse vaporizes the ablative layer, creating a plasma cloud that is confined by the water layer. The rapidly expanding plasma generates a pressure shock wave (1-10 GPa)2 that plastically compresses the metal, ...

Re: Bah!

I've seen hotel doors with a big knob to double-lock the door, that make a big "thunk" when they are turned, and that have absolutely no effect whatsoever.

However you need 2 people to test it - one to use the keycard from the outside and one on the inside to lock it. So no-one ever ever tests it.

Yes, its obviously just theater. Surely one of the attendees could have found a way to infer the amount of metal in a room? Or inconspicuous metal detectors in the hallways? Then they could bring the police along to a search when there was an actual suspicion.

National ID cards might not mean much when up against incompetence of the UK Home Office

ciaran

Some things the government should know..

I think the government should know all the people who are legally resident, if for no other reason than to tax them. So there should be government-issued cards with your name and face. From there you can bring along any other documentation to prove anything you need proving like your date of birth. I see no reason to put your age, sex, social status into the card.

The card should have an ID number which should mean absolutely nothing - it should just be an external key into a database, and it should change every time you renew the card. The card should have an expiry date, of course.

Re: I'll have some of that business please

Frankly they are lucky that the older F35B are still usable. The aluminium structural components need a special treatment called "Laser Shock Peening", which is basically impossible after the plane has been built. Of course that only became evident, or even possible, after the testing showed that the plane was dead without it.

I love it when Lockheed Martin claims that the change to aluminium bulkheads from Titanium - only for the B variant - has absolutely no effect on the lifespan of the plane. That kool-aid must be good, but I'll stick to the beer...

Re: and Pigs might fly a.k.a F-35

In any case if you turn on your radar you're not stealthy any more.

No matter how much hi-tech jumping around you're doing, if you outputting 10's or 100's of watts of power, you will be detected passively by anyone in range.

ECM is a good approach. It helps if you're not built like a mirror, so having a small radar cross section is an advantage. How small is an economics calculation vs. the cost of the ECM. In this the french Rafale is a better design than the Eurofighter.

No real commonality in the F35

bombastic bob says "the benefits of having a common airframe "

Sorry bob, there's only about 25% commonality between the different versions.

Each version of the F35 has different wings, for example. The F35-B uses aluminum in the central body while the others use titanium.

The current projected "Total cost of ownership" is so high the USAF is saying its unsustainable.

The actual underlying design is flawed for current needs. Its range is too short, and the body too wide. The US Navy doesn't want it.

WTF?

Cameras or Lidar?

So, ARM chips inside? Don't care. What I want to know is what sensor technologies are going to be used!

Waymo is using Lidar, accurate but impossibly expensive. Lidar is great for close-up obstacle avoidance but gets even more expensive if you want 1-second notice of an obstacle when you're doing 130KM/h.

Tesla is using cameras, which are cheaper and should be similar but better to human eyesight. Tesla add a normal radar, but I'm not sure if they know what to use it for.

ARM has reference platforms for handling video feeds in an automotive environment, I don't know if anyone has picked it up.

GPS is bad at measuring height

Basically no, the height part of the GPS measurement has a much larger margin of error. The lateral measurements are best when the satellites are low and well separated, while the height measurement will be better when the satellites are basically directly above you.

Also you want the height over the ground, but the GPS maps don't have accurate surface height information. The GPS measurement gives your location on a sphere, which the earth isn't.

Re: make the whole MoD military personnel

The Army, Navy and the Air force are all permanently at war... with each other. Why do you think the harriers were scrapped? Kill strike from the Air force.

The MoD is there to try to keep them apart. Their basic tactic is to say 33% each. So actual needs are not considered. If the army wants a budget increase to buy, say, new guns, its going to cost the MoD 3 times the price to keep the other 2 happy.

So if the military were in charge, it would have to have 3 co-chiefs that sign of on every expenditure. War by meetings. With meetings.

Blue sky basic income thinking is b****cks

ciaran

He missed the point

The basic income plan is actually a right-wing libertarian policy. With a basic income (which would only prevent dying of starvation) you can abandon lots of social protections like minimum wage, discrimination, employee persecution. When people aren't scared to walk away from a job it reignites the "free market" for employment - treat your employees properly or tomorrow you won't have any.

Equally you've got a great idea for a new product? Fine, go an live in a garage for 3 years with a few buddies to see if it'll work, no worries if it crashes.

Want some work experience? Fine, go an be an unpaid intern.

Want to restart manufacturing jobs? Since your employees are already getting a basic income, how much will the workforce actually cost?

The author says that people are never happy - of course not, that's why they'll go and get a job!

Laser-zapping scientists will save the Earth from meteorite destruction

Or an anti-matter beam!

My favorite plan for asteroids is to fire anti-matter at them.

Like anti-protons for example. Expensive to generate, and you'd have to do it on the moon, but easy to shoot and 100% of the incoming energy would be absorbed by the asteroid. If it was taken over by a mad scientist they could only attack earth's satellites, an anti-matter beam wouldn't make much of an impact on the atmosphere and would only create some gamma radiation. Same thing if the beam missed the asteroid or was dispersed.

The effect of the beam on the asteroid would be to generate thrust, and should work even if its spinning. So it should be able to deflect the asteroid minutely. You'd have to start early, its not a quick process...
