The voters hate Google. Heeeeyyyy... how about a 'Google Tax'?

Too Simplistic

I think your conclusion is based on a too-simplistic view of how Amazon operates their retail business (the cloud is a wholly different pan of eels).

Whilst the customers order is taken on the web (just what country is that in? ), the order is delivered from a gigantic warehouse in the UK - it takes 5 minutes to drive past their warehouse outside Glasgow ON THE MOTORWAY. So the revenue is declared at the website operation, but most of the cost is incurred in Blighty. I daresay that sufficient revenue is assigned to the UK to cover operating costs, CAPEX depreciation etc., but not enough above that to incur corporation tax.

So the key here is how the revenue is assigned. If it were assigned to different centres in proportion to their (genuine!) costs, no taxman could complain; however it isn't.

Perhaps the real problem is that megacorp s.a./ltd/inc. can do this, but Bloggs the plumber (or indeed I.T. contractor or employee) isn't allowed to.

Re: Bluetooth woes?

Wow. I was confused by your BT requirements, let alone the phone & cars. I take it your cars won't connect as full BT speakers then (mine won't either)? Surely you could transfer/copy the audio onto USB stick(s) to plug into the sound system, leaving off the earphone jack connection?

Consensus & Modelling

Examples of "scientific consensus" from history:

1. The Earth is flat and you'll fall off if you go too far.

2. The Earth is at the centre of the universe, and everything else revolves around it.

And my favourite:

3. Nothing heavier than air can possibly fly (there was probably a bird floating by in a balloon at the time).

The current condition of the climate change issue seems to me to be strikingly similar to number 2 above at the time of Gallileo: The "consensus" view is rigidly supported by dogmatists (religious back then) who subject unbelievers to legal and bodily sanctions - being burnt at the stake. Meanwhile, genuine science was progressed with difficulty, as observations were progressively refined, until the new theory eventually became orthodox. Here's hoping that proper climate science can also progress in the teeth of "religious" dogma.

I've spent my career (o.k., in the oil industry) running, and supervising others running, computer models of physical systems. Just because a computer says down is up, it aint necessarily so. The idiot machine can be wrong in so many ways - and this is on much simpler systems than an entire planet's climate!

Garbage In Garbage Out (GIGO)

Convergence errors (one oil co. I know nearly built an offshore platform far too small, because the convergence criteria were too relaxed. Many others had units which had to be replaced or removed after startup. This is always a good one).

Just because the computer is precise - to 16 digits- doesn't mean its accurate.

and many more. Lets not even look at the problems with equations of state...

So from experience, models are ALWAYS wrong. You just try to get them as close to right as is possible. For climate models, after a mere 20 years or so of development, they will not be very good; and development is hampered by the surrounding religious fervour. Computer models are an ENGINEERING tool, not a SCIENTIFIC one. Human interpretation is still required

That gives wriggle room for bureaucrats to demand stupidly simple conclusions that allow them a wonderful excuse to regulate a whole area of human activity they had hitherto been prevented from interfering with.

Bloody Advert!

There's a bloody advert in the top right hand corner which obscures the article text down that side. It won't go away & can't be closed. If this is what the Reg is heading for, I'll be off!

Radiation & Convection

Lets get your understanding of heat radiation up to speed:

Heat radiation takes place even in a vacuum (obviously, otherwise we couldn't see/feel the Sun).

Heat **convection** is what drops as the ambient density goes down, because the currents of air wafting past your heat source can carry away less heat because of their lower density. I remember 1 of my lecturers commenting that heat loss is dominated by radiation for a small temperature difference like 4 deg. C. Hence the results of your REHAB experiment are what I would have expected: Now, if you had put a more powerful heater in your hyperbaric chamber (bigger delta-T) maybe the result would have been different...

I just checked. API 521 (520 is for sizing of relief valves) 5th ed. states solar radiation = 790 to 1040 W/m2. My previous nos were in Btu/h-ft2, for other criteria.

It gives time-to pain thresholds of 1740 W/m2 for 60secs, 6940 W/m2 for 9 secs and 19870 W/m2 for 2 secs, amongst others.

In Aberdeen yesterday the sun was acting as a heat sink, so 3.5 W/m2 for Newcastle sounds about right...

It so happens that 790 W/m2, impacting on yer ear, gives about 2.4 W/ear

Solar radiation is taken to be up to 500 W/m2 when doing sizing calculations for oil platform flares (350 W/m2 max in UK).

API 520 has an interesting list of how long it takes to burn at different radiation intensities.

Oh yeah, that's mostly IR rather than microwave, of course, which is more energetic (IR that is). Although IR doesn't excite the molecular bonds in water like 2.4 GHz microwaves do...

@millifortnight

Erm - no. A millifortnight is about the time it takes a normal person to walk a mile. If Usain takes that long for 200m, I'll have a go against him, for the right money...

Isolated human genes can be patented, US court rules

Wrong!

That sounds like the wrong outcome. If I understand correctly, this ruling would mean that nobody else can develop a process to look at the particular chemical sequence that is patented without negotiating a licence with the patent holder. So the holder might have a monopoly on testing for breast cancer via DNA checks.

A better outcome would be to grant a patent on the *process* used to look at the sequence. Then anybody who develops a better process to look at the same sequence can get a new patent and hey presto, we have competition!
