small scale solar like this is quite inefficient compared to grid-scale stations.
grid-scale generation is much more effective, both in cost and generation efficiency.
Can you explain a bit better on the magnitude of these differences and why they exist? Thx
No apologies needed. Great that we got here. Cheers
Have you made simple mistake on your original comment?
That source is about the use of dried luffa, a cucumber like vegetable.
You commented about
dried sea cucumbers
From the Wikipedia article on sea cucumbers, "they are marine animals with a leathery skin and an elongated body ... found on the sea floor worldwide."
Thus me having asked for a source.
This somehow reminds me of the plastic industry ploy to discredit cork stoppers and thus get wine with plastic stoppers. ---- No. No, the production of cork does not require the killing of the cork oak tree.
I'ma gonna need a better source for that, k !?..
Better for what?
Moving parts and complexity makes it more prone to failure.
Also, how much energy do you need to keep this working? It's not said on the website.
Granted, both kettle and this zori trade energy and complexity/failure-potential for convenience. Much more so the zori. How much is unknown. On the simple, less-energy end, you'd use an electrical resistance in an insulated jar.
All electric kettles will fail at some point. They have moving parts and are designed for obsolescence.
In my place I use a kettle that allows me to boil 1 cup of water. The filter mesh has failed long ago but the water does not have hardness. Instead I use a small improvised cap to keep the flow of vapour to the cut off thermostat (usually at the bottom of the handle).
