Bi-metalic strips: power aint your problem. Just install more. The problem is temperature: in the winter the panels are going to stay facing east while in the summer they are going to stay facing west.

From my experience: fear usually inhibits creativity. Thus a FDD shop is probably not really innovative. This may seem suitable for run of the mill work, even there I wouldn't advise FDD. All your good programmers are going to wise up and get a new job, in a company like Gazzonyx's.
I remember the Tower of Babel, all 37 feet of it, which I suppose was impressive at the time. And when it fell, they howled divine wrath. But come on, dried dung can only be stacked so high.
They give away Athlons for 10 bucks nowadays. If you could burn your custom asic into that, even if you wasted most of what used to be the Athlon; it would be fast as shit running your FPGA program natively. One you paid to lay it out, seems to me it might be cheap as shit to run a few thousand of them, and saturate the area with these detectors. Which feed already vastly condensed data that we would be capable of capturing.
That is just not how it works. You can't convert an athlon to a custom ASIC. The part that is the Athlon is the hardware. To make a custom ASIC you need to make different hardware. That means making masks (cost a few million $), testing, making new masks, testing, running a batch, testing, testing testing. With this batch size it isn't really interesting unless they need the additional speed ASICs bring.
FPGA's and CPUs are different enough that it is hard to compare the speed. For some tasks FPGA's are way faster, for most tasks CPU's are way faster. Think of the FPGA as a hummer and the CPU as a Ferrari. Most driving is done on roads, where the Ferrari is faster. However, in rough country I would bet on the Hummer.
Take your final FPGA and burn chips from it (I know they do that). Run a hundred, and CERN might pay 20 grand a chip if they're good enough. I made that number up'; I don't have a clue, but that's where I'm going with my question.
Converting FPGA programming to chips means you need to invest millions to produce masks. You ain't gonna do that for a few hundred if you can avoid it. Those chips are called ASICs. They are usually faster then the FPGA. And if you need many then they are cheaper.
That the models predict an amount of lithium with narrow error bars. It's a really neat prediction, it just happens not to agree with the measurements.
Since the cars drive 11 mph according to TFS the bikes are the fast ones. They have to limit their speed to match the slow cars. The pedestrians are even slower than the cars so the speed delta is bigger for bike-pedestrian accidents. Besides, dunno about the US but here the sidewalks are often paved with 30x30 cm (1 footx1 foot) concrete tiles. Those are unsuitable for bikes because they are just not flat enough.
'Round here (NL) better bike paths do usually increase speed for cars, because a percentage of drivers start biking. Then there are less cars on the road and thus less congestion.
Helium leaks slowly through a fully welded vessel. Really slowly. If they use fully welded vessels the leak rate is around 10^-12 mbar*l/s. That means half the helium will be gone in approx 5 million years.
Still, that is approximately what happens. Partial pressure put simply: Forget absolute pressure. What matters in leaks is the pressure of each gas individually. There is 0.00052% of He in the atmosphere. Assuming 1 bar of absolute pressure this means there is a partial pressure of 0.0000052 bar of helium in the atmosphere. If the drive is filled with 1 bar absolute pure helium the difference will be 1-0.0000052 = 0.9999948 bar. That is the pressure that is important. There is no way the helium will not leak out. There is no such thing as a closed system. The system will also leak air in but far less. The result is a vacuum in the drive. In the end that vacuum will be filled with air but that takes far slower.
Now how long will the loss of helium take?
A 3,5 inch drive is about 0.3l. I assume that half of that is filled with hardware so I assume 0.15l He. A properly welded system without any connectors is probably in the range of 10^-12 mbar*l/s He leak tight. If I assume the drive will work at 0.5 bar helium we can take 10^12*500 mbar *0.3l = 150 * 10^12 seconds. A year has 3.15 * 10^6 seconds. That is almost 5 million years. Not really something to worry about. Yes there is a leak. Yes the helium will escape. No it doesn't matter because it just takes extremely long.
With a bad weld the time would drop significantly. However, the detection is easy. Helium leak detectors are commonplace, to detect minute leaks in high purity systems.
Sources: Dimensions drive: Wikipedia. Leak rate: I can get connectors to 10^-11 as standard items (Swagelok VCR full metal seal). Fully welded systems are probably better than that.
When the helium is gone the drive will be high vacuum. The drive should include a breakaway disk (with shrapnel filter) to prevent collapsing of the enclosure. The system should detect that break and slow down the drive to 5400 RPM to fail gracefully. SMART should report the pressure inside the drive and the status of the breakaway disk.
Then you can get the data off while the drive is in degraded mode.
Those subterranean sources are being replenished by natural alpha emitting sources. When those sources are gone the sun will have gone red giant, absorbing the earth. We should have enough helium by then.
Then please upgrade the door to an airlock. If the bouncer throws someone out we have a problem with the current setup.

Actually the airco is easy.
The airco is mostly needed during the hottest moment of the day. The moment with the most sunlight.

The contracts should include a simple number "you must pay us $X each month". Then the customer can check if they can pay it.
Ah to live in a perfect world...
That doesn't mean Coca cola can solve those problems.
Stop looking. I am big foot.
I would love an app that can tell me wich of the myrad of threads a pipe connection has. Is it NPT? Is it BSP-T? Is it metric?
I expect it's protection against invasion of privacy is limited.

Any important data should be backed up.

Assuming that list is accurate it is less than 8.3%.

Thank you. At least there is one who reacts like I do.
Dump soil on coral reefs to make islands is evil. Especially for such a stupid reason.
Why are you proposing to build islands at a nanometer scale?

I really should have done the calculations before posting that. It takes almost 5 million years to lose half of the helium, assuming a proper weld.
Helium loss is no issue.
Calculations are in my reply to this post
