Hi Jim,

Yes, inflation would definitely be a factor. Guess about 50% over the last 10 years?

Probably not that much (CPI 1998:CPI2008 is 1.3), although.. copper prices are 4x what they used to be.

Fortunately, the last 10 years have also brought us significant advances in switching technology, greatly reducing the projected design cost [the original design used rotary gaps and supersonic-air static gaps.]

Also, there are notable 'economy of scale' factors in migrating towards larger power levels.

My current estimates put the NLL at just under $1/watt, in modern dollars. However folks with actual experience in planning large commercial projects feel the project will exceed $1.5/watt, although they've already shown amazement at how much lab capability and skilled resources have come to focus on this project through donations, refurbishing, and volunteer efforts.

Of course, as a commercial operation, Jeff can't really rely on volunteers, refurbishing old gear, etc. And so much of the coils that most folks build has a goodly component of both of those.
