yes it is an interesting project the old chap has been testing...NO mention 
of sun light being used  A Cable is used up thru the conduit pipe and into 
the sphere...as he places the spere in the water vessel no rise of water 
height..this would mean the water has gone inside the sphere ball 
thingie...any electics regardless of frequency would be in contact 
withwhatever hes got inside....any flow of electrical current heats water 
the same as having a heater element...old wizard zip water heaters just used 
probes in water for heating...didnt work well in southcant because of 
scaling of probes....hope he takes care with it and runs it thru isolator 
transfrmr...hope iam still like him at his great age   george zl3pn
