An airless ‘energy return wheel’ working concept by designer Brian Russell:

…instead of air, it uses rubber stretched over a series of carbon nano tube reinforced composite rods to provide its cushioning. these rods can be adjusted, changing the tension of the rubber to suit different types of terrain, improves flexing and recoil cycling. with the intention of reducing weight, a 29er wheel made from carbon fiber is incorporated. further improvements include the possibilities of implementing a thin sidewall to keep mud and trail debris out for a more consistent ride.

I know you don’t normally do this but I guess there’s no harm sending this in…yesterday my house [Dublin 6] was broken into and my bedroom and my housemate’s bedroom were pretty much destroyed. They took the main things like our laptops, cameras, iPod, jewellery, etc., (and random stuff like make up and my shoes) but the worst part is they rifled through my personal stuff and threw it around and took some really personal things…Anyway the chances of getting these back are most likely zero BUT I did have a very distinctive laptop. It’s a Dell Inspiron 15R. The lid (above) got shipped from the US and is pretty hideous to most people I’m guessing, so I doubt there are many like it in the country. I’m hoping someone comes across it…
