Is it just me, or is the world going a little mad?
No it is the English language, where new words are invented or old words used for new things. This
is not what comes to my mind when some one talks about a transformer, but clearly the word includes inductances, switch mode power supplies, and children's toys.
Kettle and Cauldron can be referring to same item, it refers to containing things which could be boiling water, melting ice, or crowd control, also the noise produced by a kettle.
My electric kettle is called cordless, however it would not work without being on the stand, and in real terms I hardly ever move it from the stand, and fill it with a jug.
There are two ways to save energy when boiling the kettle, one is only boil enough, the other is not to allow the water to cool
between using the kettle, vacuum insulated kettles make a lot of sense as no waiting for it to boil.
Or of course we could move to cold drinks, the other method to make water safe to drink is to brew it so the alcohol stops it going bad, so I suppose drinking beer is good for the environment as it uses less energy than making tea or coffee at point of use. As to in total have to include transport cost, and processing costs, clearly it takes energy to make instant coffee, or the beer kit, and coffee is rarely made with a kettle,
and these must cost to run as no insulation around the jug and it is kept hot.
So I am off to do my little bit for the planet and I am going to get another beer!
