Plus an injunction to prevent further infringement, which is of some use...

How can that be? The cost of physically producing a copy of OS X is tiny. There may be a huge sunk development cost but - no matter what it is - Apple will make money off each sale. Whether this is increasing Apple's profit from OS X, or reducing its loss doesn't change that.

OK, but bear in mind the electricity may have been generated from fossil fuels at efficiency of 50-60%, and then transmitted across the distribution system at efficiency of 90ish%, and then used to charge the capacitor (which will have an efficiency of less than 100%, but I've no idea what it will be)

All of which will likely end up better than 20% efficiency, but some way short of 90%.

This is not necessarily correct - in construing laws and contracts it's often corrrect to interpret "entitled if" to mean "entitled if, only if". Well drafted laws/contracts make this explicit. I don't know enough about the specifics, or indeed anything about Texas statutory interpretation, to say what the correct result is here.
