Free trial for 30 days and then you lose some esoteric features but the gratis version is capable. OS base maps on the site give you a start and then you can render your result in google earth to check a gpx trace for accuracy. It's fairly easy to georefernce photos ont the map (or google earth for that matter) for a report, getting the client to read it is another matter.

Yes used it for about 15 years seems quite capable

That will be covered by part J of the building regulations, download as pdf Planning Portal - Part J (Heat producing appliances)

They were (informally) issued to us in 87 after the storm. In those days the anchor at the house end was often an eyebolt to which a wrap guy lashing was attached. This lashing wrapped round the incoming wire and took the tension, the loose wire tail was then joined to the house side wire by the jellies. So it was often possible to undo the old jellies and unwrap the lashing and lower the wire. It was important to connect the two wires the same way round or it fooled fax machines, much may have changed over the years.

A requirement of all the self certification schemes under building control regulations is that the work must be done by the competent person certifying the work and that means they must be registered under one of the schemes, like Gas Safe, Fensa or Hetas. It's their being able to do this that saves them the couple of hundred quid the local building control would charge (assuming the council or contractor have expertise to do so) and recoup some of the costs the scheme owners charge in this legalised pyramid selling system. By signing it off they are taking full responsibility for the installation.

That's on my wishlist (with the drone but being close to Gatwick will a problem for that) . Anyway the OP should remember that patents are only a licence to sue and, as a barrister once told me, even with a solid case there is only a 70% chance of winning. What worries me in these litigious times is how does one get product liability insurance for small runs or one offs? A former colleague and harvesting contractor went back to university and gained a degree in design engineering, after 10 years working as a model maker and latterly engineering technician for a university designing and making bits for students experiments now wants to go freelance but insurance is the big problem.

Yes I agree, once over 2 tonne and commercial the lower limits apply, also when pulling a trailer. If it's a car and over 2 tonne it's still the higher limits. Also a dual purpose vehicle must be less than 2 ton unladen and I doubt diesel Land Rover products can get under that so when used commercially the lower limits should apply but I haven't seen a definitive cite for this.

Shouldn't do below boiling point but they do appear to lose a lot of strength in one season in sunlight.

Another similar sized beech being felled at same place next week, needs collection soon if anyone is interested. It's too large a diameter for the last bloke who collected some.

Bioregional spec was that 50% of the chunks should be greater than 50mm. Our log customers used to complain if there was too much roundwood in the mix and it may be the same for lumpwood charcoal.

I'm the same, won't sell to a neighbour or family, rather give it away instead.

if the trailer is less than 1 tonne unladen you do not need an operators licence for it. You do need to have a tacho unless covered by one of the exemptions, principally agriculural or forestry enterprise and within 100km.

Economically the new plantings post 1919 have never been sustainable the FC has always been a drain on the exchequer and the establishment costs of private planting under the dedication schemes were truly staggering in terms of lost revenue. Work we did in the 70s was some of the most wasteful one could envisage, poplar in farmland which was never harvested as well as lodgepole pine across heath and moorland that never produced a harvestable stick. These costs were borne because of a perceived need for a strategic reserve of timber the need for which has never been realised.

Please let me know how you get on, can you describe how it works in practise? Can you see your position from a desktop pc? Is position report available all the time or just when a call is received?

That was the thing about google latittude, it showed position based on the cell towers you were camped on rather than depend on GPS (which canes the battery on my samsung) so not that obvious.

Seems a useful extra as long as your phone acknowledges receipt of the sms before kitestring sends alerts, otherwise it will be crying wolf if you are out of coverage.

I'm a bit of a dinosaur with apps, can you describe its workings? Does gps have to b on all the time? can it be viewed from a desktop?

Have you tried it?

My home. In the past google latitude allowed you to see the position of "friends" on google map, if the gps was not on then it estimated the position from cell or wifi data. I am not sure why it was withdrawn but it worked quite well in the south east and yes you had to opt in and only nominated friends could see you. Not as good as an emergency beacon but okay for seeing you are safely en route home. I have an android phone so apple apps are no good to me.

Don't thinks so, just no need for operator's licence if trailer weighs less than a ton.

Can anyone recommend an app that will report approximate position every so often in the way google latitude used to without using large amounts of data?

I think you are right, also as you say LOLER does not normally apply, though a PC has recently required full LOLER on a 3 tonne winch hauling on an embankment because the load would drop if a rope or chain snapped. Outcome was a new 10mm rope and loads restricted to its 1.25 tonne SWL. In the bad old days prior to PUWER or LOLER we all used Highland Bear pulley blocks as snatch blocks. On the skyline these would keep going untill the wire rope wore through the sheave. They were pressed steel with sealed roller bearings. I attach a picture of a highlead block (currently deep inside my shed where it's languished for 30 years) but the pulley was the same and attached by a 3 tonne bow shackle to a strop. The justification was that the SWL was half the proof load which was half the breaking strain. I never broke any bits for these non lifting purposes other than the occasional wire through wear and tear. Here it is, the red one beneath the grey, one being abused with the 4tonne Igland DD. I would expect these pulleys still to be obtainable. Farmi 3 point link winches have a re direct pulley and this is of a similar roller bearing type, side plates for a shackle could easily be made. I may still have a sheave and bearings from my 8 tonne. I wonder if these gloves are still available, quite handy for pulling wire rope out but generally pull the chain not the rope.

Me too up to 18" not so sure on the 084 though.

That's a nice brief paper, I hadn't seen it and it pre dates our offering by 10 years. The thing is once you invest vast sums in the structure you must have a high throughput and the limiting factor is getting the water to move out of the wood rather than passing enough dry air over the surface. Otherwise 20 days in the summer will do the job with no artificial heat input but that's no good if you have no dry wood now.

That clarifies the difference between units of power and units of energy but if my experience with PV panels is anything similar to the proposed solar thermal tube panels then energy output on a dull December day will be less than 5% of that on a sunny mid summer day. We got 18 tonnes of 60% moisture content wood into our container, to reduce this to 25% requires the removal of 8400kg of water. To do this at perfect efficiency in 14 days requires a thermal input of 384kWh per day but this assumes air entering the system leaves it at the same temperature but more saturated. In practice you need a higher temperature to not only reduce the RH of the air in the system but to increase the water movement from the wood.
