Hi Mark , great thoughts , ( what the hell is "χόρτα" please I need to know! ) I think the idea ref taking a large ship and parking it in the middle of the Humber was not to have the engines all for movement but use it as a mainly static floating base/castle , the position in the middle of the water would make it ( in theory ) easy to defend and the shape of the hull would make it difficult to scale.
I guess the fuel could be used to power a small rib and feed off the reserves for heating the living section of the superstructure.
Anyway , nice to hear this thread still got legs , any different suggestions ????
χόρτα is a mixture of wild picked greens, the ingredients vary depending on the area and season.
Managed to find a list on wikipedia though and being a idle sod i've copied it straight from there.
black mustard, dandelion, wild sorrel, chicory, fennel, chard, kale, mallow, black nightshade, lambs quarters, wild leeks, hoary mustard, charlock, Smooth Sow-thistle and even the fresh leaves of the caper plant.
These are then boiled it's then usually dressed with olive oil and a bit of lemon.

It's actually pretty tasty and really good for you, obviously being a Brit i have it with chips and bread lol
Plus as i say the Mrs's Mum can go up on the mountain with a small knife and a bag and come back with a full meal that cost nothing.
It's really cool speaking to her as i say when she was a kid they lived 99% off the land.
A few years the crops failed and many in her village starved to death, it was also very very tough during WWII and even more so during the Greek civil war as if any "rebels" or soldiers passed through the village they'd have to feed them.
There were 9 kids and they all slept in 1 room using hay as bedding at night.
Cloth was bought in in exchange for produce and the village seamstress then made everyones cloths, a cobbler fixed and made shoes.
Hunters would go out and bring back game, and share that with the village in exchange for either veg, clothes etc etc.
During the olive harvest everyone would chip in and help everyone else, so Kostas would help Adonis bring in his Olives, then Adonis would help Kostas later.
100% of their water was from the village well or the river as there was no running water, gas, electricity etc.
Very very tough life, but i'm in no doubt that if needed most of the older generation Greeks from rural areas would be able to survive off the land if the entire system shut down tomorrow.
Cheers
Mark
