My head hasn't been functioning at full capacity recently. I made some suggestion that there may have been a blog in the works last night, but it never made it to completion, it's part way there though.
In the mean time, you may like to keep yourself occupied by checking out part of what I call my day job. I'm collecting people's opinions on transport fuels, the link to the survey is https://www.surveymonkey.com/s/sotonphd, it shouldn't take more than 10 minutes and I'll be eternally greatful.
Thanks in advance,
