I hope this helps.  But I expect you want something with much more detail than this

Dear Rick. Thanks for the Information which i  can use and implement in the project. Heliostats and CSP are so far known to me and not far from me built, in the FZ Jülich. I am particularly concerned about Senegal and mini heliostats for decentralized small applications, in Africa, in Senegal. For H2 production. I am interested in prices and application in Africa.

I've read your CV and am very impressed. Perhaps we will work together once? Also with the MIT? I invite you to participate in the Bonn Climate Project. You can find all important information here at researchgate. It will be a pleasure to cooperate with you.

Greetings from the UN city Bonn

Heinz

May be these documents will help you?

Dear Heinz,

I have worked on low-cost heliostats at NASA's JPL in Pasdena. There are some publications, which sum up the major findings. There is also a specific paper on cost estimates. I've attached the files. If you have any questions, please don't hesitate to email me.

Good luck and best regards from Austria, Armin

Sehr geehrter Herr Buchroithner

Vielen Dank für die Infos. Kann ich sehr gut gebrauchen im Gesamtprojekt, für Afrika.

Gerne sende ich Ihnen per Mail eine Kurzinfo darüber ! Wie lautet Ihre Mail Adresse bitte ?
