Isn't there restriction on buying acid for cleaning after that woman was blinded by her ex with it. And "Watch and Wipe" is a much better trade name.

Faraday Cage. Just wanted to say it, I have nothing else to offer.

Why would that be a problem, you size at the lowest level with a syphon feed, then the height differences are an irrelvance.

No. Nuclear and Tidal aren't. MGH Mass flow rate times Gravity times Height. The greater the difference in height, between the water surface and the turbine, the same amount of power can be extracted from a smaller mass flow rate. It is why we don't have turbines on many river weirs, they are just not high enough. And why, even in the Bristol Channel, a tidal turbine is not that great, in the scheme of things. 15 m of height difference is too small, the Grand Coulee Dam is over ten times the height and has a name plate capacity of 6.8 GW, twice the size of Hinkley Point C. A Barrage across the River Severn would be ten miles long, Grand Coulee is a little less than a mile wide. They would both produce about the same power, but tidal barrage is intermittent, so less energy is produced in a year.

Blind, it registers wrist movement. 30 in all. That book was written in Helston.

My local Poundland has these fitness trackers for a tenner. The previous one I bought cost about 20 quid, and has been very good.

If you could see how much damage acetone can do to a body, you may have wished it was something else. But like all chlorine and oxygen based chemicals, they are fine in moderation.

Surely a dam will impede flow. They are used to increase the head, so a smaller volume of fluid is needed. Dammed hydro electric generation is really a combination of solar and gravitation forces.

I really don't know why acetone is sold as gun cleaner. It is really pretty poor at it. Works well with polyester resins, and some epoxies, when uncured, but little else.

Good advice, play them at their own game, but better.

Yes. And your nail varnish. It can also decaffeinate your coffee. No sure how easy it is to buy small quantities, we used to get 200 litres at a time.

Or just stick it in a buck of CH2CL2 for ten minutes. How we cleaned the PU moulding machines.

Not on he forum. I use a small, portable, graphics program called Irfanview. Copy and paste the image into the program. Press L to rotate left, and R to rotate right. Then just select, copy and paste it back into the forum text box. Takes a few seconds.

Yes. Think it was a college project to see how much energy runs down a downpipe.

Saw a design that used a central heating water pump. At least all the bits are off the shelf.

Make a waterwheel connected to a small generator. True green power.

Air changes an hour as well (with and without heat recovery).

Was it easy getting it though planning?

I am not to sure about that timing. Come October, we are having money borrowed against our bills, then we have to start paying it back over the next few years. October is the time to massively reduce usage until others have paid off our loan. (expletive deleted)ing bonkers idea allowing it, I hope it gets challenged and an opt out is offered.

Does he just do he electrical side? or actually install systems?

Covers all sorts of things, including staff monitoring. It is a comprehensive scheme, abused rotten. And the built in insurance/warrantee/guarantee is a joke. Used to be called REAL, but I doubt anyone ever successful claimed on it. Probably called something else now.

Sounds very dodgy to me. Cost 100 quid to drive 300 miles in a van, and how do they check the structural integrity, rely on an unknown SE (printing up letterheads now, every town has a Number 3 Church Street).

As Siberian Larch grows on the Finnish boarder, do the Fins sell it. Get in quick before they join NATO.

Pretty sure wiring regs say it must for mechanical damage protection. @ProDave can check. I seem to remember that 80V at 1/8th of an amp was enough to kill. Same as 1 kg moving at 1 m/s. Or 1 g moving at 1000 m/s, which is a bullet. (May not be the actual numbers but you get the picture, I am more interested in the conversation on the next table, couple of Emmet that 'love the place' and want to buy a holiday home)
