For a little extra power generation. The fact that the blades are
turning shouldn't make a difference, so long as light can reach the
solar cells (light travels lots faster than windmill blades).
Lots of space available

Windmill blades have lots of surface area that could be covered with solar cells. [Vernon, May 13 2016]

Solar cells are compatible with MOVING airfoils. [Vernon, May 13 2016]

// shouldn't make a difference // |

Wrong. The incident photons will experience frequency shift due
to the Doppler effect. |
|
| |
This will be quite small, however. |
|
| |
[8th of 7], I just knew some pedant would just have to
mention that. Solar cells are not so wavelength-sensitive
that the Doppler shift matters, and therefore what I wrote
remains true, not wrong. In other words, the "quite small"
effect you mentioned doesn't make a difference. |
|
| |
Being pedantic is essential to this place..... I'm very concerned about that Doppler shift effect on the moving solar panels as pointed out by [8th of 7]. This needs a detailed examination to determine the viability of the idea, and I call upon Max to carry out the required tests and report back. |

//I call upon Max to carry out the required tests

<5min later> OK, here's what I found. For
windmills located at the North or South poles, the
Doppler shift may be significant at wind speeds in
excess of 2.5 x 10^3 m/s and blade-tip speeds in
excess of 8.888 x 10^4m/s. On the other hand, it
may not. |
|
| |
For windmills not located at the poles, the
rotational speed of the Earth produces an effect
greater than that experienced during all but the
most alarming storms. As a result, it turns out
that solar panels of _any_ type cannot possibly
work, except at the poles. This will come as a
heavy blow to countries that have erected solar
panels over most of their prime agricultural land. |
|
| |
<10min later> That's odd. I just found a decimal
point lying on the floor next to my chair. Not sure
where it came from but it must have worked loose
from one of my numbers. |
|
| |
^ It's better to find a decimal place lying on the floor next to
your chair rather than a colon I suppose. |
|
| |
If you watch long enough, the head of a woodworm may emerge. |
|
| |
//.....lying on the floor next to your chair rather than a

|
| |
// a woodworm may emerge // |
|
| |
You'll just have to hope it IS just a woodworm, not a .303 Bookworm ... |
|
| |
This idea is out there (link) but might not yet be WKTE. A
blade feathering system could angle the blades for maximum
exposure during low or windless days. |
