Because I saw the Bay of Fundy prototype on vacation, I was impressed. Another session at MIT was called "From lab space to marketplace: bridging the valley of death for emerging energy technologies" which spoke to the current absence of venture capitalists in that sector. The cost differential between a hand made prototype and a production model can be quite extreme, so current cost comparisons can be illusory. As you know, sea water is extremely corrosive and waves can destroy most any structure, so working models need to be observed for quite a while to prove reliability.

Adding some links to tidal generation of electric power in the Bay of Fundy, Maine coast. http://singularityhub.com/2012/11/01/first-offshore-turbine-for-u-s-begins-feeding-power-to-maines-grid/ http://en.wikipedia.org/wiki/Bay_of_Fundy Coincidentally, I'm attending an energy conference at MIT. Some take homes- for battery power to smooth out the irregularities of wind and solar power forget lithium batteries. What is needed are batteries as cheap as dirt and made from local dirt. Prof. Donald Sadoway on his "liquid battery". Also, "Nobody cares about energy efficiency, but they can be made to care about saving money", from a group of entrepreneurs partnered with utility companies to decrease demand. One of their clients is the GSA.

Irish anti-British sentiment does merge nicely with that Kenyan anti-colonialism. It's at least faintly possible that the IRA and the Mau-Mau traded a few rifles now and then.

Kharris is correct on morality. The absolute winner in the moral repugnance sweepstakes is the prohibition of abortion to save the life of the mother, the as in the Republican Party platform. This standard has been enacted into law in a few Latin American countries. Women have died from ectopic pregnancies which are non-viable for the fetus. Women have died from cancer that went untreated because the fetal life was prized above the mother's.

No opinion on statistics, but at least in the North, October with winter kicking in is not the ideal time to start digging holes in the ground. Are these builders counting on a mega spring selling season?

Historical note: the French aristocracy was exempted from all burdensome taxes. Due to foreign policy over reaches, the kingdom's financial situation had so totally deteriorated that the Estates General were convened in 1789 to raise taxes. Simultaneously, a weather caused famine was in effect in Paris. The resulting events are well known. The brilliant Ryan financial plan seeks to reproduce some of those historical circumstances.

Bush must be happy now that N.Korea has at least baby nukes because that make missle defense "necessary". So it doesn"t matter if it works.

Finding leaks in very old houses. Wait till it rains heavily and then go around looking for puddles, drips, and damp spots. Once the puddle is found, it's origin must be traced upwards to the missing roof flashing, the hole in the roof, or the toublesome window. I own a elaborate Victorian >100 years old and have called a roofer at least five times since I got a new roof 20 years ago. In New England one or two days of drips are harmless, weeks or months will cause expensive structural damage.

Gary Student dentists going for a DDS are OK, but graduate student dentists - for bridge work, crowns, gum surgery- are superb! So if your teeth are in terrible shape you may be lucky enough to get a graduate student dentist. In any case all the work is checked by professors. Re: Hiltzoy's desire to mix with other classes; after I was suspended from college I worked as a waitress, an experience which gave me the resolve to finish my degree and always tip lavishly. Alternatively, we made a point of living in a racially integrated neighborhood.
