It's fascinating and depressing how despite me being in a different country on the other side of the world to you, if I swap the $ for £, your comment is still accurate based on the current situation in the UK.
I've been inside Dinorwig Pumped Hydro plant back when they were doing tours. They keep the turbines spinning with compressed air to avoid the delay of having to spin up that large metal mass of turbine when they open the water valves.
Good idea! The AC in my Nissan Leaf uses about 3kw so I assume it'd be about the same in my Corsa. However the Corsa disables auto-start stop and keeps the engine idling whenever the AC is on, negating any fuel savings!
more likely a reference to "lights-out" manufacturing where you have automated a factory to the extent you don't have to provide lighting or HVAC as there are no humans needed in the production area. The robots don't need to see.
I have assumed the same about the gatwick airport shutdown caused by drones in the UK in 2018. Newspapers saying "No culprit ever found" says "results of military exercise are classified" to me...
I didn't know Russia had tested being isolated from the wider internet! I wonder what problems they had during testing? I would have thought there would be many issues given our current globally connected world. I don't think I even know which country some of the 3rd party dependencies of my apps are hosted in!
I assume all that diesel went straight into a generator for electricity? So in your opinion, could the drill rig have added a trailer full of fold out solar panels and battery storage and still functioned? (I know nothing about drilling for gold, just curious)
If you're talking about seasonal storage I would have thought the natural fit would be power-to-gas or power-to-liquid syn-fuels? Absorb all those extra kWh from the sun in summer, store it for 4-8 months and then burn it during the cold, dark winter? Energy storage density higher than gravitational potential energy and less energy leakage than thermal-mass storage due to non-perfect thermal insulators etc?
I think you may be onto something here. Taking apart old machinery I have often observed that the hardened part of a shaft is worn and has a noticable groove detectable with a fingernail. However the part that rubbed on it is often much, much softer eg a rubber oil seal. My theory is that the much softer material is so soft that microscopic inclusions of something much harder (grit?) are caught in the material and then abrade the harder shaft. Something similar may be occurring in the keys on glass case?
The device the OP puts Tasmoto on from athom.tech can also be ordered for the same price pre-flashed with ESPHome to work with Home Assistant. I have used them with 2500W single-socket loads and been happy with them for a year or so.
For whole house load I'd recommend integrating with whatever smart meter tech your country uses.
For the in-between size loads eg. 32A breakers in a consumer unit I have not found a reliable and cost effective solution yet.
Skimming the website, I assume this submersible is using electromagnetically attached drop-weights so that if anything goes wrong and power is lost, the weights drop off and the submersible floats up to the surface again?
And 96 hours of life support sounds good, but unless there is another submersible nearby that can dive down, find them AND attach a line, the number of hours of life support will be irrelevant. Of course if the pressure hull has failed catastrophically it will have been over mercifully quickly. Anyone know if deep-diving submersibles are required to carry black-boxes like aircraft?
I've often thought a smaller, faster form of transport like this would be lovely for summer day trips across to the Isle of Man. There's a currently a car ferry and scheduled flights from Liverpool airport but the faff involved in driving to Liverpool only to queue up for hours just for a 70 mile flight puts me off!
I've avoided smart-meter data so far as it shows zero watts no matter how much I export (I don't have an export contract, it's a DIY PV install and no point with current pricing) hence why I'm looking at ones with a seperate sensor. It frustrates me no end that my IHD doesn't show export, only import!
Native English speaker here that doesn't know any French and that's a great word! The word reminds me of a horse trot which is a bit faster than walking, so feels like a good description. Scooter isn't the only word to have multiple meanings, "bike" can mean motorbike or bicycle which is another one in the endless source of confusion that is English!
I do this with the Home Assistant app on my phone. When the battery level gets to 80% it triggers the smart plug the charger is connected to, to switch off.
My phone is 3 years old now and according to AccuBattery still has a battery health of 2499mAh out of a design capacity of 2700mAh (Based on 977 charge sessions for 1,215,025 mAh total)
