As I have pointed out before on vortex, neutrino harvesting is impractical. The 
power density available is at most 80
W/m^2, while normal sunlight is about 1000 W/m^2 (at best, at the surface). To 
compound the problem, it is difficult
(being generous) to extract neutrino energy, while there are plenty of 
relatively cheap methods available for capturing
energy from sunlight.
