As mood-boosters go, it's hard to beat giving out free things to nice people. Throw loud music, fancy dress and a giant wicker dragon in the mix, and you can kiss the late summer blues goodbye.

I'm backstage at Bestival 2010; Simian Mobile Disco's set is unfolding a few metres away, and I've spent the day with Bestival's unstoppable green team giving free solar and bike phone charging to the nicest bunch of music lovers you could ever hope to meet. It could be worse.

Tsega tries out the bike chargers

With a tent decked out in 10:10 finery and a giant solar array from our friends at Firefly, we were charging (and chatting) at full capacity right up until closing time. As the solar panels soaked up the rays, the more energetic Bestival-goers plugged into  special bike chargers and pedalled their phones back to life. As we shut up shop for the day, the new 10:10er tally stood just shy of 500.

We'll do it all again tomorrow, so keep a look-out for more words and pictures as the weeked unfolds. In the meantime check out the 10:10-themed video that played on the big screens today, and a few of my favourite photos from the festival so far. I'm off to catch the end of Simian Mobile Disco, then giving my long-suffering voicebox a rest.
