It seems that this is only in place at the security entering the terminal. I landed in Heathrow a few days ago and had to empty out my water bottle (which I got given on the flight to the UK) for the transfer security check.
We once stayed in a beach house with an outdoor shower in South Africa. One morning I got up, took a shower (without my glasses, I am very short sighted) and went in for breakfast. About 20 minutes later my sister-in-law comes running into the house shouting that "there is a huge snake in the outside shower"
Fully agree. Walking towards the address I came around a corner and my jaw dropped. Still get goosebumps thinking of that moment. Sadly inside was a construction site with no lighting (this was around 2003), would love to go back and see it again.
Around 2001 I worked for one of the big dot com news outlets. In our reception we had a PC with a browser set up where people could "use the internet" while they waited. One day the receptionist asked me to fix the PC as it wasn't connected to the internet and no one from IT was available. So I messed around a bit (think in the end I just reset the DCHP lease) and to test I opened the browser to surf the net.
Of course with the millions of websites available I couldn't think of one specific one, so I just held down the "x" key and then pressed CTRL+ENTER (which automatically added "www" and ".com" to your entry - typing this on a mac I see it still works with Firefox).
Of course www.x(and a few more x).com was a porn site.
Of course there were a bunch of people (including customers) sitting in reception (and the receptionist herself) who could directly see the screen.
Of course the PC was running nothing else, so a quick alt+tab didn't hide anything.
I announced that all was fine and ran for my desk.
As others have mentioned, this resonates well. But for me, not only biology. Looking back, I wish my history teacher had done something similar; taken me by the shoulders and shook me until I really understood what we were learning. Instead, major events in our history ended up being "memorize yet another date" rather than us understanding the impact these events had on us or our parents/grandparents.
I have a heat pump driven boiler and I do run it when the excess is available - it uses 500W, so I'm still left with a potential 2-2.5kW. I can of course set the boiler hotter, but then I'm just wearing out the components to lose the heat at night (since I don't need so much hot water).
I do have an EV charger, but no nearby neighbours yet with EVs.
However "sharing the excess" is an interesting idea, since everyone needs electricity. I could run an extension cable to the neighbour and let him run his washer/dryer from it at peak times.
Sure, 30kW storage is fine, but it implies you use all the energy every day (or night). In the summer months my current set up uses basically 0 grid hours (as I already have some storage for night time). The 30% really is an excess after storage, running home appliance, charging batteries etc.
Looking through some of the points above, I was somehow reminded of Johnny Mnemonic, where he puts together a computer to get online. Based on today's reality he wouldn't need all the most modern, hard core parts, but actually as retro as possible - break into a computer museum and fire up some kind of antique running code he writes himself.
