Try picking up the rear of the bike and then spin the wheel forward. It will normally spin freely with no real resistance since the Bafang motor has an internal freewheel that disconnects the motor when it's not driving the bike. .

Once again following the example of the USA where it's long been the norm for all students, regardless of ability, to go on to higher education after school, only commencing work in adulthood. .

Agreed, but better than heat exhaustion. .

Definitely not, very efficient but noisy. I use it to reduce the temperature quite a lot, then switch off. Mine is plugged onto a permanent 5" telescopic hose that I installed into the external wall, the hose recessed in and a blanking plate over the hole at other times. .

That's real science, the practical sort which actually means something! .

Our heatwaves are usually so brief I hadn't bothered to bring out my air conditioner so far this year and connect it to the exhaust duct to outdoors, but I've finally just done that with today and tomorrow OTT heatwise. Nice, windows closed and in minutes the room down by three degrees and...

It's what a raindrop makes between heatwaves. .

That insurance won't happen, but in any case it's the UK who impose the tax on all insurances, introduced by Kenneth Clarke when Chancellor in 1993 at 2.5%. Successive Chancellors have increased it by stages ever since, Philip Hammond last time to 12%, almost five times the original. Once...

Not a barrage, but there have been tidal flow energy studies at that site. Here's one such. However, the usage and importance of the shipping lanes there would I'm sure rule out a barrage, locks would probably be unable to cope with such high traffic levels. We'd also need a much higher...

The UK certainly has a long established principle of no double taxation, but no law against it that I know of. It's dependant on the Treasury and Chancellors avoiding it. .

But so is my use of unreliable, and that is what I meant, not your correction, which I still insist is a means of avoiding the truth. Electricity is needed 24/365, and no renewable can always do that. All renewables in combination and shared over large regions can meet quite a lot of the...

But I don't live in the Sahara, Spain or the USA. I live in England where the sun often goes absent for very long periods. As for dispatchable, it's "new speak". I've taken this from online: Dispatchable generation refers to sources of electricity that can be used on demand and dispatched at...

Or carbon nanotubes, or anything else that someone dreams up as a vague possibility which might earn a research grant. Meanwhile the companies that make the things just keep on making them steadily better. My new car battery a case in point. Nine years ago it started at 24 kW/h, three years...

Good! .

Very true. If they were all neutral bias they'd all end up with identical results, but that never happens. .

Of course, and why I mentioned in the following post that the remaining waste can be safely dealt with using tectonic subversion, which I've mentioned before as you know. Not so, I used a term that all will understand, certainly not the case with dispatchable, which is incorrect anyway since...

Radical battery advances are like medical ones, announced weekly, always about five years of research away, and never materialising. Basically they are grant raisers to keep institutes going. In any case the trouble with fast charging is that it's usually directly related to battery life, the...

Those are right. The tiny in-seat-tube motor that's ideal for the light bike B had 100 watts net claimed when it was released, the maker later claiming an unlikely 200 watts which I suspect was the marketing department version. However there are some small and light hub motors that can output...

I'm just as cynical where man is concerned, but I also recognise the inevitable. We don't have unlimited options where energy is concerned, unless we don't mind destroying this world. The later nuclear power stations with multi-layer computer control to minimise human error have proved very...

That is not the language of nuclear power. The three nuclear accidents of Windscale, Three Mile Island and Chernobyl all concerned first generation nuclear power stations. They were built long before a third generation was designed. .
