What annoys me about this is: The legislation is being produced to stop yuppies in the likes of London polluting their own streets by burning unseasoned wood in the wood burning stoves they bought so as they could pretend to their friends at dinner parties that they were somehow saving the planet (ignoring the range rovers and other chelsea tractors parked outside)

The result is that considerably poorer people who live out in the countryside, who have never been stupid enough to burn unseasoned wood in the first place, will now undoubtedly ave to pay a lot more money to buy wood that has been kiln dried. And do note that many of these people live well away from mains gas so they have few alternatives to keep warm.

More stupid rules that impact far more on the poor.

We have a Nordica Rosa L as our only heating. It is good because we can also cook on it and in it because of the large top and good sized oven.
We do not tend to get the best quality wood to use because we have to wait for wife's brother to source our supply with his, and he leaves it late.
I have built a large wood store at our farm last year which we are trying to keep full, so we should start off with good wood next winter

My wood pile from last spring
Not my dogs, they were my neighbours mutts, as he was giving me a hand stacking it all up

Totally agree with Hopperty

True country and rural folk generally know what to burn and what not to

Hi @simon12 , I don't know a lot about the hydrogen fuel cells other than the hydrogen is extracted from water(using electricity) , then some magic happens where by the hydrogen is used in the fuel cell to produce electricity.Could the tech be scaled up to power station size using the electricity produced by the massive fuel cells to then create more electricity, ie water in one end electricity out the other, and some electric diverted to make more hydrogen to keep powering the grid?

Don't get me wrong guys I am not against wood burners as most people us them as intended, I just don't think leccy cars are the way forward, I can see a day when like diesels were encouraged they will create more problems than good

Fraid not, you can only get out what you put in - minus efficiency loses.
However it is very efficient end to end compared to an internal combustion engine, which is why it's probably the way forward. 80% is about what you get. And if that electricity to create the hydrogen is from renewable sources, it's essentially free of carbon footprint.
Ev is a dead end in terms of practicality purely due to distribution problems
Also worth noting, you can use this liberated hydrogen and bond it easily to carbon capture co2 to create synthetic methane and liquid fuels for things that can't be hydrogen on ev powered - like planes. Therefore you are only releasing co2 that has previously been captured!

Nirvana will be when someone cracks commercial nuclear fusion tech, then all those bloody windfarms can do one.

thats a very good price your paying for logs. its £50 for one of them builders dumpy bags around my area. total rip off
I pay £200 for a 1.8 cubic meter bag of kiln dried Ash/Oak mix
£40/£50 for a bag of logs around my area means a bag of soaking wet wood that takes at least a year to get to below 20%
I “Wood” rather put the central heating on than burn that

I can't see how all this could be policed anyway but unless you cut or buy in good loads as most do its the poor in towns who will struggle with rocketed prices I think.

Wtf is wet wood?

It's seasoned or unseasoned. Simple.

One will burn in a stove happy, the other won't - to the point where you'd throw it into the garden half ablaze in frustration. I don't like it when people who don't understand attempt and/or succeed in making things a lot more complicated than they never were.

As I understand it they're only banning the sale of small quantities of green wood from places like garage forecourts. You'll still be able to buy your dumpy bags of green wood to air dry yourself. Oh, and by the way - one of those weighs far less than a ton. They're a ton when full of sand. Takes about 3 of them to make a ton of wood. Had woodburners since about 1980 and mostly cut my own wood. And I know how much work is involved in cutting and splitting a dumpy bag's worth of logs. £50 delivered sounds quite reasonable.

From Simons post above




The real reason that Hydrogen (H2) is not much considered for engines has to do with the thermodynamic efficiency of engines vs. fuel cells.

1 gallon of gasoline has an energy content of about 130 MegaJoules (MJ).

1 kg of H2 is in the same range (130–140 MJ).

At first glance, it would appear that they are pretty much equal, except that H2 costs several dollars per kg just to produce ($4.50, according to the National Renewable Energy Laboratory), which must be done using renewable energy as the original power source if we are to get any real benefit from using the H2.

However, an internal combustion engine (ICE) running on gasoline (the Otto cycle) or Hydrogen operates at thermodynamic efficiency level of around 20–25%.

On the other hand, a fuel cell that converts H2 and Oxygen into electricity to feed an electric motor operates at an efficiency level of 60% or even greater. Gasoline (or diesel) cannot be used in a fuel cell.

Putting these facts together, we see that 1 kg of H2, used in a fuel cell to power an electric motor is equal to 2.5 to 3 gallons of gasoline, and even greater for urban driving conditions.

The result is that the fuel cost per mile is equal when the price (at the pump) for 1 kg of H2 is about 3 times that of 1 gallon of gasoline.

I’m a wee bit obsessed with my moisture meter purchased for £15 from Amazon, I need to stop sticking it into the living room furniture Swmbo says
