I'm surprised auto-drive is not at commercial levels for highway driving.

The white lines should be easy for a computer to identify, any unknown hazard and you just slow to a stop and beep and flash the driver, speed would be min (100km/hr, speed to keep 30 meters from ahead car). Practically no intersections or turns.

I guess sitting behind the wheel doing nothing is boring on the highway, and being a lot more difficult problem to solve in cities - it's somewhat practical but not desirable to only solve the easy half of the problem.

But robot cars will around long before Hydrogen / Electric cars take off, see how safe they are and at what speeds their safety starts to drop.

On a pristine road in good conditions, with disciplined other drivers, and I dare say it's quite feasible to have an automatic vehicle.

Throw in unmaintained roads (including missing and altered lines), bad weather, difficult lighting and idiots, and the task becomes a lot harder.

Reliability is also an issue. Producing something that goes wrong less often than human beings do could be quite difficult. Humans have quite good self-monitoring. Sudden failure with no warning is quite rare.

Yeh plus the red tape, but while driving 1000s of kms last month it crossed my mind it would not be much more difficult technically than cruise control, veering left and right between the solid line on the left and dashed line on the right, but only on highways. An alarm would solve most unforseen conditions for a prototype alteast. Not sure your human reliability argument is apt here.

the right,

I'm drawing a distinction between making errors, and simply failing. Anyone whose had much experience with electronic equipment (and these days, that means all of us), will know that it has an unfortunate tendency to stop working, abruptly, and with absolutely no warning.

Humans can do that, for example with strokes, and to a lesser extent, heart attacks. But most of the time there is at least some warning which gives a driver time to stop.

When the automatic control system on your vehicle fails, your knowledge of that failure could be limited to the few seconds between the failure and the moment you're obliterated by the truck coming the other way into whose path you've strayed.

Even aircraft control systems, with multiple redundancy, and arguably a rather easier task, still manage to fail in unexpected ways. Fortunately, the crew have time to sort things out. A car driver won't have that luxury.

It's still 100X more reliable than a person prone to falling asleep, being distracted.

A double redundancy independant system that detected unsafe driving could simply make an alert. Airplane cruise control must be 100X safer than 30 years ago. NASA probes use 3 independant computers and vote on what to do!

**I disagree. Self-driving autos are not far away (for highway conditions). Multiple redundancy of control systems and power is easy enough. Redundancy of servos is another problem. That said, a controlled shut down, in the event of a servo fault is easy enough.

Or just a "beep" and "flash" to return to manual driving.

But there are problems even now, when my engine stalled last month I tried to turn into a street but the steering locked up aswell. Not just loss of power steering but unable to move the wheel at all. I rolled into the side street on the right hand side of the road and landed perfectly in a car park, facing the wrong way, under a shady tree!

There was a petrol station, mechanic and motel 5 minutes walk away!

**It's not about size. It's about location. The size of the antenna relates to the frequency of operation. Your TV enatenna, for example, sucks a minute amount of energy from the TV transmitters. Think in terms of pico Watts (10^ -9 Watts). And a TV antenna is not a small device. Location, OTOH, is vital. It you (could) run an antenna a few hundred kms straight up and anchor it (somehow) in orbit, you could extract significant amounts of power by virtue of the antenna 'cutting' the magnetic lines that surround our planet. Scientists are working on just that. It is WAY beyond the home constructor. Even the guys at NASA can't yet develop the technology required. The hurdles are significant.

I believe they are making a tether of carbon nanoparticles that will be 
strong enough to resist the earth's rotation. The earth becomes one huge 
generator.

Won't that weaken our magnetic field and maybe screw us up completely?

Anyone noticed that just about all the free energy schemes you see advertised on the Net require you to buy a book. Dont you think its a bit odd that no one has actually bothered to put the details on the Net .

Actually no. That's one argument I think doesn't hold water. If I had a technology for obtaining free energy I certainly wouldn't go sharing with all and sundry on the internet. Woud you? Really? If so, why? It's an easy assumption to make - if it really exists someone, sometime, will have made a video and popped it on YouTube, taken photos and stuck them on Flickr and boasted about it all over usenet/ Geocities/Facebook* - but it's an assumption that doesn't follow from any logic I can see. There are lots of things that are real but have no internet presence at all.

• Whatever happened to Geocities?

size matters. You can't recieve more broadcast power than is incident on your antenna.

Yet a larger antenna (eg a phase array) can produce multiples of that output power. but 4 times stuff all is still not a lot.

probably just extract energy from the earths spin (by deforming its magnetic field and causing drag vs the solar wind). There's an awful lot of energy there, it's been powering the tides and lifting the moon for billions of years

if the earth stops spinning we're probably screwed

If you put a coil of the right design for the frequency right next to the transmitting antenna, you might then be able to extract a usable amount of electrical energy, though its hardly practical and probably illegal.

Start going further away from the transmitter and a thing called the "square law" tends to rapidly eliminate any practical energy collection

No.

e they have seen too many incompetent, mismanaging, money-wasting Labor gov= ernments"

Don't know, there may be some old enough to remember that the Labor party back then actually stood for the workers, and did some positive things for them.

The ones that vote for them would still be naive enough to believe that they still do this,vote for them because they always have done, or are still living in the old days.

Some may just hate the liberal/national/green parties more than Labor. ;)

You are dead right on those - probably more right than you realise.

I heard about someone in the mid-80's who'd erected a large complex antenna to harness radio signals, and then modulated them down to 240V 50Hz to power his house. Apprently he was caught because no-one beyond his house could pick up 2WS.

I don't know if the story is true but it's technically feasible. It's just like a transformer except the secondary winding is some distance from the primary winding. That's pretty much how a radio works anyway...

It seems highly implausible. He'd have to be capturing a significant proportion of the total transmitter output. It's certainly an urban myth created by someone with some knowledge, but not enough.
