1 per vestibule

Given 3 hours per charge time of iPhone 5s, and 0.1 pence cost of doing so, we have a daily cost, at full utilization, of 0.008 GBP per vestibule per day. Assuming 2 vestibules per car, and a car in constant operation, with the outlet constantly occupied by a charger, we're looking at a cost of roughly 5.84GBP per car per year. Given the overall car maintenance and railway operation costs, that's noise not worth paying any attention to.

Any "solution" to this imaginary "problem" will cost more than this. Even having someone qualified write a report as to why a solution is unnecessary will cost more than the yearly cost of electricity here.

TL;DR: Making a problem out of this makes one look very, very dumb.

The best engineering is the type of engineering that realizes that the scale of the problem is such that even having anyone qualified think long enough about the solution will cost more than the yearly "losses" due to the problem not being solved. The cost, to fully recharge (from flat battery) 1000 iPhones is about 1 pound. That's a very conservative figure. I don't know how many outlets are there for them to worry about, but even if a million phones get fully recharged per year that way, we're still talking about amounts that are, for a major rail operator, not unlike rounding errors. What's 1,000 pounds yearly of extra electricity cost for them? Nothing.

You meant 0.1 cents worth, perchance?

You're overestimating the cost by 2 orders of magnitude.

Assume we were to recharge an iPhone 5s from a flat battery. You're storing 5.3Whr at, conservatively, 50% overall efficiency. You'll be taking ~10Whr, or 0.01kWhr from the outlet. At 20p per kWh, we're talking 0.20p, or 0.3 US cents. At industrial rates, it'll be less than half that.

Isn't the real GPL violation that the sources don't include the keys that are needed to obtain the binary? The sources are essentially intentionally crippled, and are not the full source necessary to obtain the binary as distributed through the app store. IIRC, mac app store doesn't do DRM of any sort.

So, hybrid and electric owners magically wear the roads less? I don't think so.

I personally would love a per-mile tax at such a rate. Heck, I'd be OK with 2 cents. I pay more than that, per mile, in taxes at the pump. I drive about 400 miles per month, so that'd be $8. As far as I'm concerned, my and my wife's road use taxes wouldn't even zero out my state tax refund, and I'd be paying less at the pump. Win-win.

There has been much improvement in lowering thread and sync primitive overheads since 10.6, as well as improving the scheduler. About the only thing OS X really doesn't like is mechanical hard drives - it performs much worse from 10.9 onwards than Windows when you have a mechanical hard drive.
