Maybe one day but for now it’s just green washed big oil
At present, however, just 2 per cent of the 600 billion cubic metres of hydrogen manufactured each year around the world is produced by water electrolysis, while 98 per cent is produced from natural gas, with carbon dioxide as a by-product.
More than 90 per cent of this hydrogen is used as a building block for fertilisers or is consumed within the oil, refining and wider petrochemicals industry.

- Comment on Wiring Check: Is the wiring correct? 2 weeks ago:
Those Shelly diagrams are confusing because it’s not clear that the diagram is the external connections. I’m used to seeing it the other way-
The SW looks an awful lot like a relay contact that is internally connected to line. Little harm wiring that wrong.
Here’s how it should be visualized
That O terminal looks like a coil that needs a L connection to energize it cause the other side is already connected to N, let’s put some power to it through my switch!

I call bullshit. I bet they knew, but saw it as an opportunity for profit and this is all PR spin.
- Comment on Could wastewater plant simply heat up water past 500C to decompose all chemicals and output clean water? 4 weeks ago:
You’d have heat exchangers, like a desalination plant
…wikipedia.org/…/Multi-stage_flash_distillation
Such plants can operate at 23–27 kWh/m3 (appr. 90 MJ/m3) of distilled water.[5]
So still impossible, but not unfathomable

I keep some in my bag for when people ask to borrow one. It sucks so bad they aren’t tempted to keep it. If they do keep it, they did me a favor

- Comment on Why can’t HVAC be made smarter? 2 months ago:
Higher trim cars have radiation sensors to help account for solar heat gain.
Honeywell has individual room sensors available that you can average or prioritize.
I think the real reason you don’t see them- the average person is too stupid to understand them and set them up.

They’re good for go karts and for auto manufacturers that want their product to be worthless about time you pay it off.

The Prius system is a modern marvel and deserve a better name than eCVT.
Belt type CVTs are trash. I don’t care that your Subaru has 57,000 trouble free miles, it’s going to die.

It’s crazy they scrambled with zero offensive capabilities back then. Not even the 20mm cannon was loaded.

It will be reachable by LAN. The gateway address is the router you use to get to addresses outside the subnet mask you set.

If you set the wrong gateway in the static IP settings or a reserved DHCP lease, it won’t be able to get out.

- Comment on Is it time to ring the alarm on internet door cameras? 3 months ago:
I did that for about 6 months, mostly to see how good the detection was in frigate (new 0.15.0 release last week, fyi) when I first got it running but the novelty wore off.
I see people in line at the grocery store watching their family watch TV in their living room. That’s creepy to me.
