Friends, I wrote about the state of electric aviation just the other week, with several electric and hybrid aircraft flying at the Farnborough Air Show. But today I was surprised to see that the Heart Aerospace experimental plane X1 had also recently flown – see the video below. This is a rather overdue milestone (link) […]
Friends, I recently received an e-mail from Octopus Energy telling me that they were going to increase my monthly payments from £10/month to £25/month – quite an increase. It’s a nicely worded e-mail but it definitely implies that I need to radically adjust the amount I am paying them. The problem is that I don’t. […]
Friends, the measurements for the next article on humidity measurement are taking longer than I anticipated. So while I make these tedious measurements, I thought you might enjoy my latest song. Many people are not shocked to find out that these are the hottest years humanity has experienced: the weather is hot and this chimes […]
Friends, people have been talking lately about the humidity of the air, and how it makes us feel. So without thinking about it quite as much as I should have, I unwisely decided to build a dew-point hygrometer. Please allow me to explain. A Dew-Point Hygrometer A hygrometer is an instrument for measuring the humidity […]
Friends, people have been talking lately about the humidity of the air, and how it makes us feel. So in a quiet moment I decided to build a psychrometer. Please allow me to explain. Psychrometer: A wet and dry bulb hygrometer A hygrometer is an instrument for measuring the humidity of air and hygrometers operate […]
Friends, other than myself and one other person, everybody I know loves to “fly away” on holiday. As far as I can tell, any qualms they have about emitting hundreds of kilograms of CO2 in an afternoon are easily forgotten once their “adventures” begin. And if they saved money installing solar panels and a battery, […]
Friends, in a recent article I made reference to a report on “Planetary Solvency” by the Institute and Faculty of Actuaries. Having read the report and reflected on it for a few of days, I think one particular point in the report is particularly worth discussing. Broadly speaking, actuaries see things differently from scientists: Scientists try […]
Heat Waves – part of a global phenomenon. Friends, here we are, in the third heatwave of the year and it feels unrelenting. Depressingly, it seems to be the case that these heatwaves are no longer just a few days of warm weather strung together by happenstance. As far as I have been able to […]
Friends, I am still perturbed by the prevalence of hot weather in these parts. This is what mild Climate Change is like: what were previously considered extreme phenomena slowly become accepted as familiar. You’ll be able to recognise severe Climate Change when it comes because you will likely be hungry or homeless. And as temperatures […]
Friends, the UK is currently experiencing it’s third heat wave of the year. It’s still early July and so there is plenty of time for there to be further heatwaves. And I just don’t understand why people are not as alarmed as I am. And so I wrote a song – please share it to […]
