Bumped up from first posting on 17 Dec 2007, as I reflect again on sustainability. See also Wikipedia for an introduction, Jancovici for a summary of a classic treatise, and Friedman for an alternative, if now old, perspective. Albert Bartlett: The greatest shortcoming of the human race is our inability […]

Carbon offsetting skydives
It looks like it will cost around 30 pence to offset a jump from an AVGAS-fuelled plane at 10,000 ft. More data required to support turbine aircraft. Not bad.
Read MoreFinishing off the trip and reflecting on carbon offsetting
We squeezed in three jumps this morning: one tracking, one fun and a four way formation. The Porter’s door is small for four big lads: So, despite practising the exit, we broke the formation while upside down and reformed before crossing over and under one another a couple of times. […]

Beautiful morning, but I don’t think I’ll bother with motorcycles or skydiving today.
Read MoreCoskata: next generation ethanol?
Try searching Digg for biofuel: it’s not encouraging, but Coskata may be: Coskata is a biology-based renewable energy company. Our technology enables the low-cost production of ethanol from a wide variety of input material including biomass, municipal solid waste and other carbonaceous material. Using proprietary microorganisms and patented bioreactor designs, […]
Read MoreI’m carbon offset! (mostly…)
Now, of course I’m trying to cut down, but I still have this house and this job… House, car, bikes and flights offset for the year ahead plus retrospective offsetting for the bikes – I’m not about to offset my life to date! Let’s see if they respond to my […]
Read MoreHard-ridden sports bikes vs 4x4s
According to Clear Offset Aggressive riding can halve your fuel economy so much that a hard-ridden sports bike could be as damaging to the environment as a gently driven 4×4! I’m glad I ride so gently! “Could” is quite a word in this context though. Riding a fast sports bike […]
Read MoreMissing sailing
How I miss sailing: exciting and no fuel burnt. Must investigate carbon offsetting against skydives… Update: Clear Offset expressed an interest. I’m collecting data from UK dropzones. We’ll see where it goes.
Read MoreThe Antarctic ice sheet
Stumbled on this article The group of Dutch researchers contends that the new estimate of the mass balance of Antarctica is as reliable as the reliability given to current atmospheric models. The only improvement that could be offered would have to come from new surface mass balance observations from poorly […]

Nanosolar reckon solar power can now be cheaper than coal: Their PowerSheet cells contrast the current solar technology systems by reducing the cost of production from $3 a watt to a mere 30 cents per watt. This makes, for the first time in history, solar power cheaper than burning coal. […]
