Isingeniso: Amashubhu we-vacuum elanga ashisa avele njengomdlalo wokushintsha umdlalo embonini yemishini yokukhiqiza. Kulesi sihloko, sihlola isayensi ngemuva kwala mashubhu amasha futhi sihlola ukusetshenziswa kwawo okungaba khona. Hlanganyela nathi ekutholeni izimfihlo ezisemuva kwale mpumelelo yezinguquko. Ukuqonda iPipe Solar Vacuum Tubes: Ukushisa kwepayipi elanga kuyi-vacuum ingilazi ye-cylindrical t
