Snuck these piccies on the home run from the last oppo.
Believe it or not, these big buggers flew right under me ol' biplane. Nearly shook it to bits - it's only an old string bag after all!
Anyhow, looks like our boffin type chaps are playing around with solar panel hybrid designs to save the old fossil fuels a tad.
They're definitely quieter, whispering buggers took completely by surprise.
Lucky they weren't the Bosch, what!
