Click through to watch this fascinating video of US Nobel prize winning physicict Richard Feynman explaining why (and how) wood burns and why trees grow from the air. Along the way he also introduces the thought that the light and heat from burning wood are simply stored sunlight. And he tells us why jiggling atoms are relevant.
Watch this and ask yourself - is wood solid solar energy?
Worth a view - and a link to send to any inquisitive children you know.
