A few months back, wheezyrider posted the schematics for the Bosch 36V charger for their drill battery. The charger has a passive circuit to stop the charging if the battery's temperature sensor detects an anomalous condition. Such circuit helps reducing the risk of fire. Some of the Phylion...

Accidents cost all of us, not just the loss of the devices, but also the on-going cost of hospital treatment, repairs to the building etc. Would you agree that government is responsible to set standards not only to protect life but also to prevent accidents? You would normally buy your battery...

we have similar debates with household electrical appliances, cars, foods, water, healthcare etc. Standards are cheaper to implement than what it would cost to insure your health or your house. Just imagine you can fit any consumer units, mains outlets, switches, gas appliances, boilers, heat...

Correct. They can avoid expensive insurance and just disappear after a big accident, I can't. It's the same with direct buying from Ali or offshore websites. On the long run, stricter standards will benefit everyone.

yes. It does not have to be brand specific but similar to what exists in public charging stations.

I do agree that the hyping is bad for everyone using an e-bike but the problem with dodgy batteries, untested, unmonitored fast chargers and twin battery kits that are lashed together with gaffer tapes and terminal strips that I see in Southend High Street need to be eliminated as soon as...

I like Lenny's posts. The fire topic is extremely important for the future of the e-bike trade. Hands up whoever sold more e-bikes this year than last year or the year before that.

We discussed a lot on nuclear power in the covid years in the brexit thread. Flecc contributed a lot to the discussion. Flecc was pro nuclear, I am anti nuclear on the ground of exhorbitant decommissioning cost. I saw no problem with burning gas for a short term (one generation or two). I...

Nuclear power doesn't have the same ROI compared to wind, solar and batteries so it's not a priority. If you look at the way wind and solar can be integrated over 1000 miles-1500 miles East West such as Western China (Xian province, sparsely populated, sunny and windy) producing electricity fot...

Google 'HALEU' instead. Instead of going for small thorium molten salt reactors like the Chinese experimental project TSMR-LF1 (also in many other countries, including UK), uranium fuel is mixed with increasing amount of thorium. That's the way to burn thorium. No planning consent is needed. The...

Low hanging fruit of Thorium. Higher burnup levels reduce drastically the amount of nuclear waste in conventional uranium nuclear reactors. At the moment, CANDU and PWR generate about 8GW days per ton of uranium fuel. By combining uranium with thorium, the burnup rate can be 8 times greater. A...

National Grid has set out a £58bn ($74bn) investment programme to revamp the UK’s electricity grid.

Australia's enbrace of solar energy is a good example of the way forward for us. Solar cell yield is improving fast with new material science advances. We are now reaching 60% efficiency in then labs. Eventually, we won't need to bolt panels to the roof but just wire the roof and windows into...

You should see the growth of solar panels and batteries in Australia. By this time next year, Australian homes would probably produce enough electricity for their own needs. A lot of EVs now have V2G capabilities. They store electricity produced by solar panels and returns it to the grid later...

They could not have done that if our electricity was not relying on fossil fuels.

does it matter another 16 trillion ponzi scheme? didn't you say the dollar is worthless? Trump will run the dollar to the ground anyway on the basis that it's overvalued.

I reckon it's a mistake to kick Pat Helsinger out. He may be too much an engineer than a money man but he's made intel leaner, fitter and given intel a better chance of survival against Chinese chip companies.

A bit of exaggeration to attract reactions, otherwise nothing new. The flames would be blue at such temperatures and they are not.

I have only seen large drones like that a few times when I was in cancun/tullum. They were flown by a bunch of Americans.

... there are easily 10 million+ drones in the USA. They have to be seen sometimes. As long as they cause no disaster to people or pets, they are just toys.
