Hi Rupert and Mark:
Here I am again after my hollidays. Rupert have reason about the generall lack of funds for innovation projects, but fortunatelly here in Chile we have a governmental well operating institution named INNOVA BIO BIO who provides funds for innovation projects, only for our Bio Bio Region (VIII Region, Chile), and so I am studying the presentation of a project for picohydro and local electronic regulators production. About blades falling from cross-flow machines I had only one experience: in a 25 kWe SKAT T-13 model working with a 20 m gross head, a flat and circular stone about 35 mm diameter came in by the penstock and stay a few seconds between 2 blades after "marking" some other 14 blades at the meedle, so the runner became suddenly stop and one blade was cutted just aside de weld in the external plate, in spite off the sloted disc constrution. The runner was taked off and the damaged blade was replaced in our works. Owner goes on again without any future troubles.
