I've been away on vacation/holiday for a while, so, best wishes to all those who have joined HW or had prblems while I was away.
And, especially for any engineers here (you know who you are!), here's a gem I spotted in the news about
how to use urine to power batteries:
www.independent.co.uk/life-style/gadgets-and-tech/video-urinepowered-mobile-phone-charger-lets-you-spend-a-penny-to-make-a-call-8713564.htmlGiven all the unwanted urine some of us are having to deal with perhaps someone can designe a pad that will power our phones. I'm less keen on the idea mentioned that it could power an electric toothbrush!
