Comment What is needed to make flying cars viable. (Score 1) 107

1 The ability to park a car, high in the air, and not have it move a millimeter until desired and to consume no energy in that state.
2 the ability to fly at zero speed and maintain position and consume no energy
3 the ability to control the position and velocity of any flying car with precision, so you could have them fly in rows in different directions in the equivalent of lanes in the sky - OR, the ability to control the exact position and speed of a car, all the way down to parked in the air.
4 power used = function of speed, as it is with road cars.

Until we can do this, the idea of a huge flock of cars, all dependant on wings with lift to stay in the air or helicopter/gyrocopter blades to stay in the air is impossible. No self flying car could do it.
The ability to 'park' in the air and use zero power.

I recall the pulp magazines of the 30's and 40's with cities surrounded by enormous flocks of flying cars as a joke until we have full spatial control of position and velocity and zero energy lift to keep them up there

Comment Automakers = conflicted (Score 1) 120

Every stolen car, and every damaged car = $$ for the automakers for a new car, as the cost of parts is so high that a small amount of true damage = writeoff. or for the repair network for damaged parts.

Better security has been easy to implement for decades, but has not been implemented due to this conflict of interest.

Secure handshake key fobs are the way. Hard wired into the computer so they can not be bypassed or copied.

What if a third party, of the other country, who has a contract that they will only release evidence if so ordered by a court of competent domain. A US court will not be a competent athority to order a non resident alien corporation to cough up the data. They could also have the data encrypted by a third party, with the decryption key not under Microsoft's control, who will not release the key if Microsoft reveals they have been ordered to reveal it - in which case once microsoft has revealed the court orders existence, the third party can cite that as a duress and not reveal the key.

Horrible? No they worked quite well, in fact so well that they caused the over priced Apples to lose share to the same systems made by others with lower cost parts.

What apple did was fail to make sure a profit came back to Apple from each clone sold, via that hard wired dongle I spoke of. That way only a true OS buyer could use it = Apple gets its profit.
Look at Microsoft, built on sales of the original OS and the descendants.

Apple is lucky it came out with the series of products it did. It is still a very small player in computers over-all, 2-3% share of that market, but it has 100% of the Apple market, but the X86 market has hundreds of players, most small, so the Apple stand alone % looks higher than many.
A good measure would be measure x86 sales from AMD and Intel and deduct the Apple portion.

Comment What a fatuous, nebulous piece of crap??? (Score 2) 161

All that memo will do (and it did) is to create a regressive hierarchy of backbiting political scum, who devote their energy to their next, larger, paycheck.
Any new ideas will be ruthlessly crushed, to avoid the risk their will succeed and toss those on high into the rubbish heap of history.
So they have done that with the company, and it only survive because of its natural monopolies in a few software fields.

Apple could have killed them ages ago, by allowing their OS to be licensed on any processor, and include a state machine rom with each licenced copy, said state machine being a soldered un-crackable dongle, so that Apple gets ~~$100 per copy - they would slay Microsoft.
As it is Apple clings to their walled garden = dumb, but Apple = richer than me, so what do I know?

Comment Re:Stop throwing good money after bad. (Score 0) 364

I agree with you. This is a fleet of flying garbage cans. G limits on the crews means they are easy targets for the latest missiles that Russia and many others have. All the money spent is wasted in most respects, but a lot of the knowledge base can be used for a new generation of pilotless planes with fight alone capability once they reach an area to respond faster than a remote human can. Remotes can be very hard. but jamming is walys possible, so fight alone autonomy is needed. There is also a need for fight along long range missiles that can hang around and interdict an area, then come back for fuel. They also need higher energy fules, boron derivaties that still use air for these remote missiles.

Comment how can they be made faster? (Score 1) 203

These printers come in 3 broad types, melt a fiber , sinter a granule and cross link monomers.
The melt a fiber you can make fastter with a jet of cold air/gas or water so the print head can pass that way again sooner, or run in a cold box = faster colling.
The trivial answer of a 20 nozzle print head = been done.

The sinter a granule, more power in laser to aggregate more granules?

Monomer cross linking, higher power laser, more reactive monomer?

I find it hard to achieve a ten fold speed ramp with rate limited physical processes standing in the way of speed ups.

Comment Re:One non-disturbing theory (Score 1) 304

The term plastic covers many materials. The ones made from hydrocarbons - polyethylene, polypropylene etc are gradually attacked by bacteria. If they are very thin as in plastic bags they are short lived. it is a little lighter than water, so it floats and gets the cross links broken by UV light unless filled with something heacvy, clay, TiO2 etc and might sink.
These are not long lived, nor are they hard, the scraping tongues with erode them, and a few cyles = gone.

If you replace one or more Hydrogen with fluorine or chlorine you get items that are not metabolized by any complex organism, however bacteris can colonize them and they remove an atom at a time, so they eventually go away.

These are all soft so the scraping of tiny teeth turns them into small particles and the bacteria get at them.

One big problem with small particles is their lack of nutrition, so the small animal wastes energy to gnaw it and gets nothing back. Too many small particles and they starve to death via metabolic losses. People can starve on some foods that take more energy to digest then they yield.

Recently microspheres for cosmetics have been released into the water and they get through filtration plants = starvation again for the small fly if there are too many.

The rise of biodegradable layers has helps plastic go away sooner, if we made bags from starch film, if would be eaten in weeks in the sea

This tells the tail of an inquiring mind that turns it's focus on many things. He reminds me of Fenman, among many similar Nobel Laureates, whose curiosity was not limited by a 9-5 mentality, but was active 24/7.

Comment Re:ICANN has changed (Score 1, Insightful) 73

If the UN is any example, an independent ICAAN will turn into the corrupt instrument of the nations that compose it and will control the new ICANN and then a new regime will levy taxes on the users - and these taxes, which they will call fees, will be spent uncoltrollably to creat an edifice like the UN, 200% corrupt. THE US congress is similarly corrupt, as we see by the FVV and Internet lobbyists.

I do not know how this can be prevented, apart by not letting it fall into the control of these crooks.

That said, ICANN is already a little crooked...
