This article pretty high on the hype, and pretty low on details. One thing it leaves out is that these turbines are specifically for floating farms; the article glosses over this, and espouses its usage on fields and prairies. The 3-fold claim is high, too - the University Professor the CNNGo article on wind lenses claims a 2- to 3-fold increase.
That article also explains - a little - how the technology works: the cowling works as a focus, forcing more air through. Anyone have additional sources for how these things work?
If US power consumption stays linear (currently rising by approximately 65,000 GWh/Year), and we had converted our entire line of power production to LFTR reactors by 2006, we would have required approximately 80,319 tons of Thorium fuel between 2006 and 2100. At ~$107,000 per ton, that’s pretty cheap. Less than $9M. It’s mind boggling that LFTR reactors were killed by PWRs, simply because PWRs can be used as a part of the manufacture of weapons grade fissile material.
