rear disk brakes: The DWG22C needs 180mm rotor. How big is your rotor? It's a skilled job but not difficult. You can learn to lace a wheel with Youtube video in about 2 hours. Getting an LBS to do that for you will probably cost about £70 + the cost of the spokes.

Hi Karl, If you go for a rear hub motor, you will need a high torque motor like my 48V DWG22C. You will have to relace it to a 36H 24" rim to suit your cargo bike. The hub motor's flanges are drilled for 12 gauge spokes. 14 gauge spokes are thinner and more flexible so usually preferred for...

Microsoft only agrees to buy electricity from Helion. It's an advertisement coup for Helion's investors such as Sam Altman who runs OpenAI. If Helion manages to produce electricity by 2028, they both win. If not, they have nothing to lose. The issue is Helion's approach. It's unlikely they'll...

I am not saying that technical solutions for fusion are readily solved but they are well within our understanding and reach. I suspect that the reason fusion is still a long way from in use is because energy companies are all powerful and controlling to the extend that they dictate government...

we will have invented magnetic shields powered by fusion rectors before we have long term missions there.

I don't think saneagle supports Tate's view litterally. He tends to use the third person in his narrative so not to mix his true thoughts with Tate's.

The Times article started with this 'AI systems are powerful enough to kill many humans'. Hello? where have you been in the last decade or two? Machine learning is the previous name for AI. Just look at our various weapon systems and drones, which ones don't have machine learning components in...

he is a libertarian. I reckon he does not mind winning or losing an argument. He's just taken up the defense of the weak, in this case, Andrew Tate against the BBC interviewer. Tate isn't liked by you and me, but he's free to spread his version of blokeism or worse. How Tate is making a living...

do you want to start WW3? :p

there is usually more water in the rocks than on the surface, even on earth. Anyway, we can make water with basic chemistry. The main thing is we need to develop small fusion reactors with a diameter of 2M or less that we can carry on boats, planes and spaceships.

We don't need to colonise Mars for living space, at least for the short term. The idea is to advance our understanding and science. AI is going to put a lot of humans out of work, the pressure is then on to reduce the over population and the need to grow food will be vastly reduced. We'll stop...

people always say about nuclear fusion: it will be here in 30 years. However, it may this time: Magnetic control of tokamak plasmas through deep reinforcement learning | Nature Basically, the main problem with tokamaks is how to confine the plasma continuously. It's juggling the current in a...

Look at the progress in quantum physics since 1900s. Moving our whole solar system to another part of our galaxy may be possible. All we need to to call up a black hole.

I have been following space missions for decades and am well aware of all the difficulties, to the point that I could believe that the first moon landing was a hoax (flag fluttering on the surface of the moon and all that...). Still, I believe that space mining is possible and perhaps we could...

I am not sure you are right on this. Our technological era started less than 500 years ago and look what we have done so far. I don't think temperature is a big issue. We don't need a million year to either to be wised up or wiped out. We can send humans to the moon and soon, to other worlds in...

they are right to be worried. I was given a test account on Adobe Firefly last month. Apparently, Nvidia is going to do even better and faster this year. AI is now trained to think like humans. It used to be trained on outcome reward, now each step in the process is given points, so AI learns to...

we don't have anyone in Taunton but we have an agent in Bristol who can look after your bike.

You can use the DWG22C for cargo bikes, up to about 250kgs and your average speed is likely faster than 8mph. Pedicabs are heavier and slower.

The DWG22C I sell only goes up to 60NM max. I don't see it capable of hauling weight at any speed below 8mph for long because the low efficiency is going to shed so much heat that the permanent magnets will demagnetise. Furthermore, the internal gearbox is not robust enough to withstand frequent...

Stunned? Astronomers study those jets for at least the last two decades. JWST has made their job much easier. They are at the point where good theories about dark matter and dark energy can soon be tested.
