If there are updates for your 2006 mid-year Lesotho Africa cogenerative solar thermal and electric power project, would you please advise how I might access same? I believe this project included innovative new uses for very economical automobile power steering pumps, alternators, etc. I've presumed that you used a refrigerant gas to power the rotating power steering pump. If this is the case, was the pump's normal rotation reversed for this new function? In normal automobile power steering use, I assume the pump's internal shaft bearings, etc., were lubricated via the circulating power steering fluid. Was this internal lubrication a problem when you substituted the (? non-lubricating?) refrigerant gas? What is the refrigerant gas you chose? Did this refrigerant gas go through vapor / liquid phase changes just as it does when used normally in a refrigerator / freezer application? What was a typical delta P (pump inlet vs discharge)? If this was a 2-phase use of the gas, what was a typical delta T used for the phase changes? I am very interested because I was issued expired US Patents 4,270,521 & 4,438,758. Please reply. Thank you, Carroll (Cal) Brekke
