Well, I don't know what they're planning, but ISTM that if they divide the storage area they can greatly extend the time at which they're generating energy in exchange for nearly halving the peak generation capability...and without much pumping (which adds an additional inefficiency or three).

OTOH, the amount of energy that can be generated by water stored at a particular height depends on the fall distance. So the potential generation capability will vary a lot as the tide changes. Maybe some of the inflow could be used to drive a hydralic ram to lift some of the water higher than max high tide level. But that *does* introduce additional inefficiencies.

All in all, I don't know, but it looks pretty iffy.

You don't need a huge tide, that just makes it more efficient, and cheaper to build, and requiring less land and construction. So perhaps it's only feasible in a few places, but any country with a coast on the Atlantic, the Pacific, or the Indian Oceans should be able to make it work with enough effort and expense. Most of them just wouldnt' find it practical.

Tidal power would seem to have a lot going for it, but there's probably a good reason that it hasn't taken off before now. Of course, that reason may have been solved...

For that matter, cost overruns are also likely on large nuclear plant projects. (Every one I've heard about has had a significant cost overrun, of course there's a huge selection bias...)

The reason we have ISIS is that we were in such a rush to leave IRAQ we didn't bother to finish stabilizing the situation.

Seeing as Vietnam has been mentioned, I'll point out the exact same thing happened there. The war was brought to an acceptable conclusion and we pulled out before stability had been achieved. The cost that time was 4million dead Vietnamese and Cambodians. What do you think it will be this time around ?

That's all very nice, but MS is a software company. I'll admit I was thinking of cross-platform development environments, like their announced open source .NET, about which I know little, and I don't really count stuff they sell as end products. I will acknowledge that this is bias on my part.

OTOH, ... you actually use those things on a tablet? As other than file viewers? (You didn't say you did, so perhaps I'm misunderstanding you.)

That said, if I'd been thinking of consumer end-products I'd never have made that statement. MSOffice for Apple has been out for ages...and MSWord 5.2a for the Mac was the best word processor I've ever used. Far superior to any later versions, and it fixed a lot of bugs from the previous versions. These days it wouldn't be so good as, of course, it didn't handle unicode, but that's still the only improvement that I know about.

While I agree that there's no good evidence that Jesus, per se, existed, there's some evidence that a person somewhat similar existed several decades before the time Jesus is supposed to have lived. Or at least someone who promulgated the doctrines that Jesus is reported to have promulgated. (Ignoring those of his disciples that diverge from the "red letter" text.)

It's been awhile since I looked at this so I can't be closer than "several decades", but it was somewhere between about 40 years and about 400 years. (Not a big help, I admit.) I think it was related to the Essenes.

Also I would be very careful what you wish for here. Anybody who doesn't have the capital or desire to become a participating entity could be screwed over royally here.

It would be far better to take patent trials away from juries. Picking people at random and then pointing them at highly technical patents isn't something that even sounds like it might work.

To be fair, at the time MS adopted the CRLF line ending style there were *four* standards, none of them dominant:
CR, LF, CRLF, and LFCR (called line carriage return). They picked one existing standard, and Unix was already using another. The supporters of the other standards have died off, so there are only two standards left.

So don't blame MS for all the bad decisions. Only some of them. I still wouldn't want to use their software, though. Perhaps if they live up to their current "We love FOSS" line for a decade or so I'll change my mind, but currently it just feels like their latest lie.

Well....... if you'd said the point of human group organiztions is power, I'd agree with you, and as religions are human group organizations, that applies to them, but not any more to them than to the girl scouts or "Citizen's committee to suppor the libraries". The big ones are a bit more successful, of course...

The real questions are "How much effort do they put into accomplishing their ostensible purpose relative to the amount of power they have?" and "Are they a net benefit to humanity?" I wouldn't trust any member of an organization to honestly answer that about the organization he was a member of. Or even to realize that they were being dishonest.
