Ads worse than begging banner?
When I think I once gave 25$ to WPF. Now, I'd rather have ads than a begging banner. Or maybe I should add it to AdBlock...

Yes. Active 3D TV glasses are prone to losing sync, provoking eye strain and eventually a headache. Now let's hope Panasonic won't restrict its 32" screen to Europe like LG does (LG must be assuming every North American home runs a DIY movie theatre; I just want to look at my own 3D photographs in my living room.)
I take 3D photos in caves using a pair of Canon G11 compact cameras. I normally view them as a left-right pair with a stereoscope. A 3D screen would be most welcome! I'd be happy with the regular 3D model (I got plenty of circular polarization glasses from Avatar at Imax;) I'm afraid a glass-less 3D screen will be very expensive while offering a very narrow field of view.

An electric motpr has an excellent energy efficiency at varying speeds, while a gasoline engine is only (yet still less) efficient at constant speed. It is thus more efficient to burn "stuff" in a constant-speed generator to charge a battery and use that electricity to power an electric motor that will handle well the speed variations than to power the wheels directly.
