On a new type of battery

 A bit of an old article but one I just came across (a bit of a click baity title though: This Wonder Material Could Eliminate Dead Batteries Once and for All. In essence, a piece of graphene that gathers energy from the kinetic energy of gas molecules. Sounds interesting, hopefully this will pan out.

On covid-19 death statistics

 I became aware of this published data a few weeks ago via this  Unherd  column. Since then I have checked occasionally for updated figures, and last week started to analyse the data. First I downloaded every data set from this  archive  page, going back to May 2020 (where the archived data begins, so note that Month will also include all deaths earlier in the year). I was particularly interested in page 3, the deaths by age, and pre-existing conditions. I put each week's figures into a single spreadsheet and made monthly total tables.

So, let's go through some of his questions and try to make a realistic prediction: First, he posits ' would this utterly trash Britain?' he also states ' London is responsible for a whole lot of the British economy, but it’s sorta the “fake” economy of financial stuff, not growing stuff or making stuff.' Well, first off there is the issue of all the banks being vaporized, along with all their ICT systems. I'd hope they have backups but it could be that the entire payments system ceases to function. The result for the rest of the UK would be no one would be able to use a credit or debit card, withdraw cash or even access their accounts. Guess we'd be back to cash pretty sharpish.  In addition, all the insurance underwriters (Lloyds, etc) wou

 After reading Longrider's post earlier I had a look at the ONS data he linked to and decided to present it visually.   From the data set mentioned above, here are the figures of interest: And here is it presented graphically: Finally, here is the data for last year as a pie chart: Consider this whenever you hear someone in the media going on about how women are 'unsafe in our streets'
