I understand rhat the letter rating is important if you want to rent out a property, as you can only do so if you have a good-enough energy rating.

The first bit about the first canals included some pointless brief shots of early trains a century before they were invented.
It also underestimated the advantages of canals over roads by saying a single horse could pull a 30 ton barge, especially as it also included shots of broad beam barges that I think could carry at least 60 tons.

No.
Heat pumps are a terrible scam.
On a radio phone-in last year, someone was complaining that, after having upgraded her insulation, putting in double glazing, and replacing her gas boiler by a heat pump, she had been rewarded by her house being awarded a lower energy rating than it had had with the gas boiler. This was because the star rating reflects running costs and the cost of the electricity required to run the heat pump was greater than the cost had been to run the gas boiler.

I don't actually know what is eating the bait. I have now ordered a motion-sensitive nature cam to try to establish what is taking it.

We have a rodent problem in the garden at home. I bought what is said on the label to be "Formula B+ advanced rat killer". I started putting it out two months ago, but judging from the undiminished rate at which the bait is continuing to vanish, the rodents seem more likely to die of obesity than poison. Its active ingredient is "0.0029%w/w (0.029g/kg) Brodifacoum."
The label says it should eliminate them within 35 days and if that doesn't work, call in a specialist.
Can anyone recommend a rat poison that works for them?

Taken by a souvenir hunter?

It has been mentioned on another thread about navigation lights that you can't just replace a filament bulb by a LED. The design of traditional navigation lights requires the presence of the compact filament of a tungsten bulb positioned accurately with respect to the refracting elements of the lens in order to produce the necessary sharp cut-off in beam angle.

My uncle used to have a metal cage rat trap in his shed that he said they used to use before the war when they lived next door to a stable. He said they always used to drown them in a bucket of water. However, there was a newspaper report last year of someone being prosecuted for drowning a caged rat, as it was not considered to be a humane way of killing it.

Gaffa tape can provide an effective quick fix in emergencies. Preferably degrease with meths first.

You can get small tins (typically 14ml, = 1/2 fluid ounce in imperial) of transparent paint from shops that sell plastic model kits. I use it for restoring the colour of traditional incandescent christmas tree lights and for colouring clear bulbs when no coloured replacements are available.

The law here AIUI, is that if a person digs away the soil on his land he is responsible for providing support to the neighbour's soil. He or she cannot just allow the neighbour's land to collapse or subside as a result of their excavations.
I would think that the land slip would be considered to be an Act of God as it is not a result of positive action by the landowner.

Yes, interesting. There is no commentary so you can mute the sound if you don't want to hear the music.

My experience is that, whenever a government encourages you to do something different, its not to benefit you, but to save itself money. So you are usually better of maintaining the status quo. As per the encouragement to contract out of SERPS and move your occupational pension to a private pension debacle a couple of decades ago.

Regarding technical drawings, the various projections were only just being decided upon in the early 19th century, so anything before that tends to be more of a sketch than a detailed technical drawing.
I understand that the modern engineering drawing conventions that we use today, were first devised by the French, and were considered to be so much better than previous practice that they were originally classified as a State Secret.

No doubt waterways will be featured in it.

At least we will still have the Llangollen due to it being also used to convey drinking water to the Midlands. I seem to recall that it was only maintained as a navigable waterway after WWII because a manager insisted that keeping it navigable was essential so that maintenance craft could access the many sections with no road access.

This is still being broadcast at the time of writing, no doubt available from their web site later. I missed the beginning and came in when they were dewatering Telford's masterpiece, then dealt with dredging the Monty, currently interviewing Mr. Parry who is discussing funding.

I remember reading that the records of one of the old canal companys were lost when their offices received a direct hit in a bombing raid during WWII.

Automotive fuses continue to use the old practice of rating fuses by the current that will make the fuse blow. For other applications, such as the fuses in your 13A plug or domestic electronic equipment, fuses are rated by the maximum current they can carry without blowing, which is normally half the automotive fuse rating.

A couple of decades ago, wasn't there a story in the papers about an incident in, I think, India, where a cow that was being transported by air, broke loose, fell out of the plane, and hit and sunk a boat? I remember it coming up in an episode of, I think, "The News Quiz" or "Have I got News for You", where one of the panel was the formidable wife of the "Cash for Questions" MP whose name I forget.
Google found this: a Japanese fishing boat sunk by a cow that had been stolen by some Russians, and had got free and fallen from the military transport aircraft it was being carried in.

As an example of practical vs. theoretical disconnect, I seem to remember a question about the terminal velocity of a cow thrown out of a high-flying aeroplane where the answer began "Assuming a cow is smooth and spherical..."

At college, one professor was fond of posing occasional questions in tutorial exercises that could not be answered because insufficient information had been provided.

Your sensation of comfort is determibed by the balance betwern the heat radiated from your body and the radiant heat received from your surroundings. My first house was a 1920's-bulit end terrace with solid brick walls where the living room was next to the outside wall next to the side entrance. When I redecorated the living room, before applying the woodchip wallpaper that was all the rage in the 1970's, I lined the wall with the thin expanded polystyrene plastic that used to be available in wallpaper-sized rolls before the potential fire risks associated with polystyrene wall coverings and ceiling tiles was appreciated. I found that after applying the polystyrene wall covering and before applying the woodchip, on entering the unheated room from the unheated hall, I immediately felt much warmer. I assumed that, because the surface layer of the expanded polystyrene was extremely thin, and underlain by insulating pockets of air it had a very low thermal mass. It could therefore quickly be heated by heat radiated from me and reflect heat back to me. Once the woodchip paper had been applied and painted with emulsion-paint, the sensation of warmth in the unheated room, vanished.
So I can quite understand why you would be able to detect the presence of a cold substance such as a cold radiator.

One sunny easter morning after overnight rain, the first lock we went through had freshly-painted wooden balance beams, black with white ends. The black parts were bone dry and slightly warm to the touch, while the white ends were still covered in rain drops and were icy-cold. Which to me conclusively demonstrated that black bodies are significantly better absorbers of radiation than white bodies. Logically, the same ought to apply in respect of radiation emission, which is certainly what I was taught at school.

Electric Boats
in Boat Building & Maintenance

As it is being used to transport staff associated with a hydroelectric power station, presumably no problem with availability or cost of electric power.
The Green Maritime plan envisaged that ferrys were likely to be the only class of vessel for which pure electric power would be practical.
