     As I said the GT inverter already has shut down circuits and can't by code.   There isn't a way for it to hurt a lineman.  Please show in actual gridtie equipment how that can happen?   And as I said even if it did it would short out.  Basic physics.

         I live in Fl and would have went into production of RE but only utilities can sell electricity here by our gov bought and paid for.  Not only that but the ratepayers have to pay $.03/kw for 10 yrs to buy Progress and FPL 2 new nukes each for free!  So I'm doing EV's instead.

Jim, that's incredible. Although back in the 70s and 80s we experienced similar resistance, to put it mildly, from utilities here in California about buy-back, it's now an established practice.

It took a really long time for the polycrystalline wafer-based PV market to achieve the solar power holy grail of volumes high enough to drive down cost-per-watt. But then it seems like a very short time elapsed before it went to oversupply. This isn't atypical of semiconductor-based markets, but it is disappointing.

Grid parity is certainly a worthy goal, but questions remain about the real cost of building back-up systems to prevent blackouts when the sun's not shining. A recent editorial in The Wall Street Journal stated that renewables need "up to 90% of their capacity back up to revent blackouts." As long as we pay twice (or at least an extra 90%) for our power generation, solar will be a niche.

FPGAs are the glue logic in today's systems, but what they glue together are a variety of diverse sub-systems with different interface requirements.
What should be the perception of a product’s real-world performance with regard to the published spec sheet? While it is easy to assume that the product will operate according to spec, what variables should be considered, and is that a designer obligation or a customer responsibility? Or both?
Procurement actually means well. There is no question that procurement can do a better job of phrasing their questions or making connections between engineering’s goals and the processes underway. And if you are using the right deciphering code, the result can live up to -- or surpass -- your expectations.
Internal combustion engines are ruling power generation applications even today, and improvising them to churn out every slice of power is still an area of research for the engineering community.
If you are interested in adding FPGA technology to you engineering toolkit, grab some free tools and an evaluation kit and get started on your own FPGA project. It never hurts to expand your engineering toolbox, and FPGAs are only going to become more popular over the next few years.
