Meet the “Nuna 5” – the fifth generation of solar racing car built by a team from Delft university to enter the World Solar Challenge.

What is the challenge you ask? It’s a 3000km race across Australia (from Darwin to Adelaide) using a car powered entirely by sunlight.  Cars must maintain a minimum average speed of 50 KM/H between checkpoints, run standard road tyres and have no more than 6 square meters of solar panels. The rules don’t say much about the drivers apart from specifying a minimum weight, but looking at that car I doubt I’d fit…

Wearing a baseball cap at night wouldn’t be my first thought, but this one has a twist: It includes a couple of LED torch lights under the peak.

Using solar power to charge the batteries during daytime, the included LEDs will provide light for 4 hours on high beam or over a day in the low-power mode.

The electronics are stormproof and the light is angled down so you don’t blind the people around you. If you use head mounted lights a lot, this seems like a useful alternative to the conventional “elastic band around the head” approach they usually take.

They’re available for £29.99 from www.solarlightcap.co.uk in a range of colours and styles.
