Brust, you're missing a big bit of how I see it. First off, the ORC's are totally sealed, zero maintenance and don't use steam, but freon as the gas, thus the need for a gas turbine engineer to design a system with the turbo blades and stages optimized for whatever freon is cheapest and/or least likely to be under attack by some enviro-wackos. I had an 'ah-ha' moment a couple weeks ago. The whole turbo-generator system needs to be one single component. There should only be sealed electrical connectors, freon in and freon out lines, and the units should be "stackable" so if you need 10KW, you plug two together. A 7KW generator at Sam's is one large with a Honduh motor. I see no reason an ORC generator should be any more, mass produced. A Garrett turbo cartridge is three bills installed. How much more complicated can it be than that? The turbine side needs to be multi-stage to get the efficiency from the system. Blade design, materials, number, etc., all needs to be optimized by someone that knows what the heck they are doing. The magnets and coils can all be in the same housing, eliminating the need for any type of seals on the turbine. It might even work to put the magnets on the outer edge of the turbine wheels, or maybe cast the magnets as part of the blade design to cut complexity.
These 5KW units should be 220V, just plug them in, with a master/slave for phasing. That way, you could plug them into the grid and get the phase off of that, or plug another one in daisy chained and use the phase off the previous one.
Photovoltaic panels are not zero maintenance. One problem is that they last 20 years, and the price break even is... wait for it... 20 years. For various reasons, the price of photovoltaics has not dropped several orders of magnitude along with everything else made from silicone. Also, the efficiency isn't all that great.
You can buy an off-the-shelf ORC system now. It is just very, very expensive and it doesn't need to be. It's just a turbine and a generator in a sealed can, like a compressor in your refridgerator, which the Chinese are turning out for nothing. I only say to outsource the production to China or India because we have zero ability to innovate or produce anything in this country at this time. Maybe after Great Depression 2 has turned the corner and trade barriers are put up to force us to hire Americans to produce things so they can pay taxes, then we can build it here, but today, it would have to be sourced overseas.
My goal is about a grand per unit, cost. Oh, and no true world changing idea ever profits the person who came up with it and did all the work. Just the way it is. There are plenty of examples and damn few exceptions, if any. So, that's why I say Berkeley it, just sell the things at cost to anyone that wants to cut their electricty bill from $350/month (or more, wait for it) to $0/month for only a two large investment in the ORC unit, a solar collector, pump or two and a radiator.
