You have to factor in the cost of building something into the economics. Also as I noted before we have a far greater capacity to build onshore wind as opposed to offshore. The reason we build offshore is there are few people there to object. Wind Europe "Wind energy is the cheapest source of...

13 years is a long time to be receiving 350W for. Price in the UK in 2017 was about 15p per KW hour. If you assume it was working about 90% of the time that's 7.5kw per day for 13 years. Or £1.12 per day for 13 years. £5k worth of free electricity allowing for £100 materials and 20 hours wages...

Nuclear - Fission not a popular choice - Agreed plus without nuclear fuel recycling there is just not enough Uranium. With recycling then lots of countries have the bomb or nuclear waste is being shipped around the world. Nuclear - Fusion not sure why you like it with fission. The only problem...

I have a pair of those. Seem to be well made for what they are.

To build offshore requires specialist crane barges and the people who use them. Those people are coming free from the oil rigs but there are limited numbers. The bigger the wind turbine the more specialist the factory to make them will be. On shore the bases are no different to a bridge and...

Cut the angle on the end of a longer piece of stock, Then you have some means of holding it whilst you hand saw, track saw etc. Then cut the end off to produce the wedge.

Whilst the offshore turbines will generate more power than onshore they are also more expensive to build and maintain; maybe twice as much. The places where the onshore wind is built tend to be in leafy areas with wealthy well connected people.

Even if your vanity water has none of the crude in it seems like a good idea to use it occasionally so new chlorinated water is drawn into the pipe. I am now thinking that I should do that with my outside tap. I have a tap on the inside so I can drain down the outside during winter but that...

I worked with a person once who was on a coach trip in France. The coach stopped beside a cliff which had water falling down it. He decided to brush his teeth, was told to stop, but carried on. Ruined the rest of his holiday.

They were obviously making allowance for any future movement by using stainless rebar. If the joint ever opens up the stainless rebar will still hold the old and new slabs together. Normal high yield bars would just just if there was water because there would be no cover. When we had finished...

I have installed studs in diamond cored holes into the side of a bridge over four railway tracks, two Railtack and two Underground, who were very interested in what we were doing. We ran a hammer drill down the holes but I doubt if some of the hole was not still smooth in many places. Then...

I am no planning expert but if you where next too the beach or a large river you would have no neighbours on the boundary. (apart from the crown on the foreshore and who ever owns the river but!). Other wise you always have a neigbour is just a matter of what they are currently using the land...

I see no reason why you could not use a screw but there could be problems. The resin may react differently if it is thicker because the screw is a lot smaller than the manufactures recomended stud, maybe set slower or worse. but if you get a resin that works in a small hole and the screw is the...

I missed out this point from EC2 "" SECTION 4 DURABILITY AND COVER TO REINFORCEMENT 4.1 General 4) Corrosion protection of steel reinforcement depends on density, quality and thickness of concrete cover (see 4.4) and cracking (see 7.3). The cover density and quality is achieved by controlling...

If you read the thread you will see that people before me talked about placing type 1 under the slab. It seems to be a common recommendation / practice on this forum. I would assume it is recommended because it is free draining, so will not be susceptible to frost heave which is why it is used...

Cover is very much to stop rusting. Why do you think different cover is used in different situations. If you look at old reinforced concrete structures you will see that where the concrete has blown and the rebar is exposed it is normally close to the surface, not enough cover. Your...

Fibre is more for anti crack rather than strength. Good enough for smaller slabs if you do not think the ground will move and lightly loaded. Concrete is good in compression not so much in tension. The slab will act as a beam with the top compressing in most cases and the bottom in tension...

A the meat on a joint cooked in a slow cooker just falls off the bone.

Or video it then you can fast forward it.

and pressure cookers.
