hello

i have been looking for long time how to convert solar heat energy to electricity and found some intresting ideas!

first i was looking how big corporation do it and found that there is something wrong with explanation of the system , for example PS20 Solar Power Plant in spain , wiki says that its convert concentrated solar heat to make steam and power the steam turbine ... but when i look at pictures of this plant i see non of contenser or steam exoust , clouds or other indication off steam !! isnt it streange? steam plant with no steam?? well 20MW turbine sould produce some nice clouds!! that gets me thinking that it needs some further investigation.

and so there is some new technology that converts heat directly to elecrticity its called AMTEC or alkali metal thermoelectric converter
that uses alkali metals compounds also known as salts and works besicaly by heating the salt to ionization temperature (energy) so salt give off electron and when cooled it takes electron so efficiency of the process is 31% but can rise to 40% and i have to say its alot!!

what you guys think about it maybe we sould give it a try !! there are salts that gives off two electrons when ionized !!!! will it double the efficiency ??

hello

im still in research but i can share some links,so if intrested take a look

still looking for something like ion separator by heat or light wave...
