We don't chop firewood, but we bind it

About wood energy.
1. Brushwood is a source of renewable energy. How much is it formed annually in England or Canada? Can liquid fuel from wood replace fuel oil?
2. Working mechanisms spend the least energy if they work evenly, continuously, for a long time, and optimally slowly. Example: cars use less fuel on the highway than in the city. Therefore, a reasonable robot independent of humans will prefer to collect brushwood, but not to saw trees.
3. How much do you need forest robots https://www.bostondynamics.com, how much should they cost to make wood fuel cheaper than oil?
“Most bizarre thread of the year ...”
Soviet engineers do not think like British engineers. Details in https://www.eng-tips.com/viewthread.cfm?qid=461144 (On Bragg diffraction in antenna technology). This can be useful for everyone.
“I want one of those robots!”
Come to Russia immediately. Someone will help you steal it. It will be too late to do this in 5 years.

Simple answer you can make an alternative fuel to diesel from wood but at the moment UK government have not authorised its use as road fuel.

Is English your second language?

Looks like a good solution to cure coach potato obesity.. those twig bundles will burn so fast who ever is loading them onto the fire will get a great workout getting up every minute to throw some more on the fire.

late father in law said his in laws used to put 1 peat at a time on the fire and left the door open when they went to get it.

I remember you mentioning this before - what bit of government have not authorised it?

Customs and Excise

Customs and Excise

Diesel, HVO and FAME are all taxed at the same rate. Why won't they also tax this stuff like that?

High proportion water which is not taxable. rape oil has its own rate and they assume charcoal is a fossil fuel when its actually produced from woodchip. Should not be rocket science but as a diesel substitute that any farm could produce I think they fear a loss in revenue duty if every farm started to produce it.

The water's not taxable but it also doesn't contain any useful energy so you'll have to use more fuel by volume, so it won't make any difference. Fuels are not taxed by energy content anyway.

Veg oils are taxed at the same rate as diesel - the lower rate was scrapped years ago. There's an exemption for personal use under 2500L p/a though.

Water is full of useful energy, remember its only two hydrogen and one oxygen the trick is in releasing that energy. Problem with 2500L thats less than 1 hours production what do you do for the rest of the year.

H-O-H is the base energy state though John. You can't do anything chemically to it to release more energy!

So in your world the age of steam never happened.

Steam was a medium to transfer energy, not a source of it. The energy came from whatever was burned to boil the water.

Not on about where the energy comes from where on about water producing useful energy. In a charcoal slurry used in a diesel engine the useful energy of water is produced when it is turned from its liquid state into its gaseous state all done within the cylinder of the diesel engine.

No, sorry you're writing nonsense. Water cannot 'produce' energy by being boiled or otherwise vaporised. Even the most basic understanding of entropy would tell you that. Where do you think the energy comes from - splitting bonds or something?

Seems you need a lesson in steam. Why do you think boilers explode.

They explode because the vapour pressure exceeds the capacity of the boiler, with the energy coming from an outside source. There is certainly no energy generated from the steam boiling, and it actually consumes energy in doing so.

Given my degree majored in chemistry and was from an institution founded by the inventor of the steam engine, I’d like to think I know what I’m writing about.

You've gone off topic now , the question is do you bundle twigs with string and burn the result .
