1903 six HP steam engine powers modern off grid power system

Looks like Mr. Desai is now making steam engines by modifying industrial air compressors. Based on the photos, it looks like he is mounting double-acting steam cylinders and valve assemblies to existing air compressor systems using the stock air compressor piston as a crosshead. Looks like the quality of his steam engines just went up.

I see on this page... http://tinytechindia.com/Template/in...POWER%20PLANTS
(9) STEAM POWER PLANT 10 KVA (FOR ELECTRIFICATION) COST US$ 9000/- with CD
Not a bad price for so much.

Any videos of the new units in action?

I haven't seen any videos of the new units. I see no reason why the new units should not be superior to the old units. Funny, but I think I may have first suggested this modification to Mr. Desai after he informed me that the city in which he lives is known for the manufacture of Diesel engines, but I can't be certain as that was more than a year ago. You see, modifying engines in this manner is not new. Either way, it seems a good decision to have done this. Now, if he would only concentrate on increasing the efficiency of the unit, then he might end up with a good product.

BTW, at first I mistakenly believed Mr. Desai used an air compressor for the mod, but he is in fact using a two stroke Diesel engine.

NOTE: I believe it's worthwhile for someone with the inclination to acquire a small unit with the goal of modifying it for better performance, especially higher efficiency.

Internal Combustion engines are blasphemy

Just making a general comment. With the price of natural gas so low and projected to remain relatively low for some time, I expect residential scale absorption chillers to become available over the next few years for air conditioning applications. There has been some discussion during the course of this thread about providing for air conditioning (i.e. space cooling) in the off grid setting, and I have mentioned several possibilities. Now that I've done a fair amount of research on many alternatives, I am convinced that absorption chillers using water as the refrigerant and that operate at a high vacuum are the most practical and effective solution. Well, "practical" might be a questionable term to use as cost effective units are not available on the market. Besides, those that are available are not only expensive, they are also complicated (unnecessarily so in my strong opinion). I'm convinced that the working principle is so fundamentally simple that a functional unit can be built by an individual with sufficient dedication. In short, if anyone starts down the path of considering how to provide a/c in the off grid setting, then I highly recommend you take a long hard look at absorption chillers. Once you have a good understanding of how they operate, then I think you'll settle on that option. Again, I expect units to become available in the near future. Perhaps a good solid unit will become available at a good price, and such a unit might be suitable for off grid use. If not, then I truly believe that building a unit is not unreasonable for those with sufficient incentive.
