looks lovely. But where did all the millions of tons of coal end up that was once in the hole, and all of the energy and resources used to extract said coal? Ah, yes all floating around in our atmosphere. If you burnt all of the old turbine blades in a incinerator you would still be in no worse...

Unless you have some actual figures then this is just propoganda by those that don't want to move away from oil. If it takes X litres of oil to make a windturbine and install it and run it for 10 years and you make Y amount of energy, as long as Y is more than the amount of energy you get from...

Hi, does anyone actually find Gorilla glues any good? I bought some PU Gorilla glue to repair a shoe and it has been rubbish. Didn't hold for long and was difficult to use due to the foaming action. Applied as intructed. I borrowed some contact adhesive to resole my sons wellies and again...

Yeah. I worked as an IT tech in a large secondary school 3 years ago. It had quite a lot of kit. I got friendly with the head of D+T so I got to use the equipment for bits I wanted to do. Quite useful having access to a big metal lathe. Made all the knobs for my guitar and a handbrake lever for...

Job done, it exists https://www.altendorfgroup.com/en/machines/altendorf-hand-guard/. This is a sliding table saw with AI camera system which retracts the blade if your hand gets within a certain distance to the blade. I'd probably prefer sawstop system as it relies less on a computer doing the...

There are more and investment and experiments with wind power in large ships again https://www.bbc.co.uk/news/technology-66543643 don't know how well it faired but seems like a good idea considering we explored most of the world with sailing ships. I like the idea of airships. Can't use Helium...

It's not a daft gadget. You may disagree with it, but it is not daft. It does the job it is designed to do i.e minimise bodily harm in the event of blade contact. Nothing daft whatsoever about that. It not only protects the user but will also protect anyone who, for whatever reason, decided to...

It's always interesting when we look at something new in isolation. If we compare it to the current offerings is it that much different? Sure hydrogen is low energy density compared to other traditional fuels. But it is lighter than batteries, which are fast becoming a 'normal' energy source...

Something to consider perhaps is ensuring there is a route for any leaks to go to a place that it can be easily seen or cause the tenant a problem. E,g a tray or lino that directs the water to the front on the cabinets so they get fed up of getting wet socks and tell you about it. Might also be...

Step drill is best suited to thin materials like sheet metal. It is a cone shaped drill that has steps so you can't drill all the way through and normally only cuts ~5mm depth for each 'step'. So not really suitable for doing what you want. sandpaper will work but will take a while if you have...

Sadly it does happen in the real world but mostly because of greed or ignorance. CFCS, HCFCs, Acid rain from coal fired power stations, fertilizer run off, carrying 10x the weight of a bar of soap because liquid soap is 'better', production of thousands of tons of pumpkins each year for people...

Not unless you painted your car with aluminium compounds like the hindenburg, which basically created rocket fuel, and even then it was more incendiary than explosive. According to this https://www.world-energy.org/article/3409.html Hydrogen fuel is as safe, if not safer, than petrol. We've...

in ~40 years (assuming current reserve estimates are correct) we won't have a choice. Regardless of climate change or pollution, fossil fuels are finite. They will run out, no ifs or buts, just a question of when.

not really sure what you are arguing? You want more births? The human species has been around for 100's thousands of years and didn't need 8 billion of us to last all that time, and stands a much better chance of surviving if there are significantly less of us. Also I didn't just say predators...

True, but you are missing the reason for this. Population dynamics in the animal kingdom that rely on high birthrates are due to high mortality rates. Populations fluctuate as disease and predation come and go. Population increases - predators increase - population decreases - predators decrease...

If the frame is complete the only way I can see you can do this is to have an open mortice/tenon, so you slide your mullions in from the rear and it is then all locked into place when you glaze it.

Isn't Jarrah wood one of the hardest woods around? If I was working with that I'd be sharpening my tools in any downtime. Between jobs I'm normally tripping over the things I've got kicking around for other jobs. I have far too much stuff in my garage. Not fantastic stuff, just stuff that will...

What I am not understanding in this scenario is that if the water pressure is really way over what it should be, all of the neighbours would most likely be experiencing the same problem! They will be on the same water main and, unless works have been done, will be on the same connections to the...

2 things I normally do to remove old nails- First tap the nail in a tiny bit further (assuming it's sticking out enough). This will loosen the nail, reducing the force needed to pull on the head. Second put something under the hammer or crowbar head so that the direction of pull is as vertical...

Yes everyone. UK tax payers, everyone who pays into the system to have it given as tax breaks for a multi-billion dollar American company so they will grace our shores and import a load of chinese products, whilst paying as little to workers as possible and syphoning off as much money as they...
