It is a well known fact that penguins and marine mammals are great fuel sources. Amusingly, penguins have even been used as fuel to render down whale blubber to create the biofuels of yesteryear. The swedes have developed a modern twist on animal fuels with their cunning bunny burning system. Scientific american outlines the process here: scientific american

Imagine how much fuel we could generate and the benefits to the environment that could be made by implementing a similar system of burning bunnies, hippies and possums in New Zealand.

I thought I would take the oportunity to bang on about tubeless tires after hearing about Mikes disapointing prerace shenanigans last weekend. I have been running tubeless for a couple of years now and I have never had a flat. While this is the main advantage, tubeless systems also weigh a smidge less than tubes, not much less but it is weight saved at the most effective bit of the bike. 

There are several options but I am only going to mention some cheap ones that dont require fancy rims:

Ghetto tubeless: cut a 20 inch tube down the seam around the outside and stretch it around the rim with the valve in the hole. then stick the tire over the rim, squirt in some sealant and blow it up. Chances are this will need a compressor. then use a sharp blade to trim the excess tube.

Rimskinz: these use a strip of open cell foam that you insert into the rim. I found these really easy to install and they inflate with a track pump. Made in NZ. One of many tubeless conversion kits, though most of these are much more expensive.

Home brew: some people even make their own sealant. this link also has some amusing photos of tubeless tires burping, the result of breaking the seal when pressures are too low of the tire is not tight enough

I am currently using tubeless rims (no spoke holes) with both UST and normal kevlar bead tires, though I ave used rimskins in the past and they were great. 

The next round of the PNP series is on the 11th of october on mt vic. Youse should do it. Details are here

If you do go I suggest getting there reasonably early so that you can enter, which may involve a queue, and still have time for a warmup. The first task is riding up that track from the velo to alex road which would be a right pest on cold legs.
