Is there any information out there on timber framed geodesic domes? In particular joinery.

I have access to 4x6 southern yellow pine (4 sides machined) at $1.75 a linear foot and a local machine shop with a 4 axis cnc machine willing to do cuts at $1.15 per angle (each timber needs 8 angles for a 2V dome) on pieces up to 8ft. I can't really do anything useful with such small pieces other than a dome. The longest piece needed for a 24' dome is just shy of 7 ft.

I've purchased the TF Joinery and Design Workbook which is the best subject matter reference around but weight distribution and loads are completely different in dome structures.

You can see examples here.

Questions:

Can a "biscuit on steriods" be used when joining ends together?

How would I calculate the size of the timbers needed to be structurally sound?

Is there an effective way of calculating loads?
