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 love History but so much of teaching it in school boils down to just periodization. There are such interesting patterns at play, over millennia, mixing geography, psychology, technology, economy, you name it. Whatever humans do. It's fascinating how much a systems understanding of History can teach about the world around us. But yeah sadly in school it often boils down to lists of names, dates and periods.
When I was younger, one of the parents in the neighborhood was a bread delivery driver. I can still remember her ranting about an incident one snowy winter day. She couldn't drive as fast as all the other trucks on the highway and they were complaining to her over the radio. Her response was "I have no traction, I'm hauling a load of bread!"
A truck carrying bread is pretty close to the weight of an empty truck. The fuel efficiency of this truck is better than a truck hauling a load of flour. But... my guess is that per kilogram of cargo, hauling flour is much more fuel efficient than hauling bread and therefore it is better for the environment to haul flour around and then bake the bread as close to the source of consumption as possible.
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.
If you store 30% for 3 hours, that's 90% of peak generation. It seems, by law, you could then finish selling that excess power for the next ~1.3 hours at your maximum rate (less storage inefficiencies).
You could figure out what time of day rates are highest, because that would imply you're releasing the most pressure on fossil fuel generators.
