Would be great to see a picture?

Just do a search on here probably around 2010 for the original solar kilns then thermal solar around 2015. Nothing really to see but a polytunnel with sloping roof and a concrete floor to allow a fork lift to move the IBC containers in and out of the polytunnels.

I do wonder if the British hesitation to adopt softwood logs is resultant from so much bad press about tarring up chimneys,

British or international hesitation?

Simples then sell more than 2m cubes a time , more profit in a day than doing the usual 1.5m loads we do.
Will be impossible for us to reach the 20% in the north ,the logs will reach what’s in the environment, we can get them down to 15% in summer but it just goes back up in winter to around 20% and that’s with two years or more storage and then 10-8 months in a barn.

power loss in the grid and distribution runs at about 7.7%

I remember reading a little while back that electricity generation efficiency from fossil fuels is typically around 66% and that distribution losses are similar, hence total efficiency only around 33%.  Which is the main reason electricity is so much more expensive than gas or oil.  Is this not the case?

, I really don't think that there is an justification for burning timber to dry firewood

But how do you dry the wood to use in kilm in the first place.

[trigger_andy]

British I feel. We don't have the quality hardwood supplies that central and southern Europe enjoy and we don't adopt softwood universally as I understand they do in Scandinavia.

From my experience Scandinavia, Norway at least, almost exclusively burns Birch. Not only because it’s so abundant over there but to keep up with demand they import huge quantities of it from a Eastern Europe. Soft wood is seen as a building material and as almost all houses are made from wood the demand for softwood as a building material is also very high.

In the Book Norwegian Wood Lars Mitting does not speak of soft wood in very favourable terms and also sings the praises of Birch. He describes the Norwegian attitude to softwood as “kitchen wood” no use in a stove and only fit for short, fast burns in the kitchen oven.

From my time in Texas and visiting a few folk I work with there Hardwood is the only thing they burn, they would not burn softwood. Of course this is just empirical evidence. Also viewing hours and hours of Milling videos based in the US the opinion I’ve gathered is they also burn mainly hardwood.

I don’t know much about Europe but they also seem to like Birch in the North and olive wood in the south.

I am not disputing what you say Andy but this is all culture, and local convenience etc.  The reality is how effective a firewood is has nothing to do with whether it is softwood or hardwood,  Well actually that is not quite true - softwood gives slightly more heat per kilo once dry.  But this is all irrelevant compared to the one thing that matters - how dry it is.  And this is why people think Ash is so good - because it dries so easily.  In fact it has half the water in that most woods do when freshly felled. 

 

But as we can't all have Ash what it really comes down to is moisture, and this is where the softwoods score - they dry really fast.  So from a commercial point of view I would rather sell softwood as it is much easier to process and dry.  I would happily argue with customers and tell them they would be daft to stick with hardwood.  I am currently converting my customers to briquettes as I have stopped firewood altogether.  There is a lot of resistance initially, but most people now are coming back for seconds and thirds.
