lenny linked an article about how to make better LED bulbs. It is estimated that LED lighting saves about 10% on electricity usage compared to before. Future improvements depend on testing various combinations of semiconductor layers to make up the LED. The author of the paper works on a piece...

They can do that because we don't have enough renewables and battery storage.

F. Merz is possibly the most able leader of Europe at the moment.

That would interest MikelBikel. Hands up those who have read the article you linked to.

The voting participation varies from election to election. In times of economic hardship, more people turn out to vote for example. If it's true that 20 million voters are frauds then how do you explain that their crimes are not proven in courts?

Let's be real,voting fraud was never an issue before Trump, he made it an issue in 2016 and 2020 and 2024. In-person wilful voting fraud is extremely rare, can only be influential at local levels, not at presidential election. Wikipedia has this: Incomplete SSA records are not equal to frauds...

People change address, move abroad etc. Keep in mind that those databases were built since a long time ago. Overtime, you'll have a lot of changes in the structures of the databases to accommodate changes. Just think of someone born in Cork, worked in London then died in Amsterdam or somewhere...

wrong chargers kill batteries and may even set fire to your bike. All my batteries with 21700 cells can be safely charged with 3A chargers. The 36V 20AH and 48V 15AH batteries can be charged with 4A chargers but you need to keep the charger where it is well ventilated because high current...

Agreed. I have the same problem with inventory although at much smaller scale.

The lifting of anti-dumping duty will certainly help sales in long term.

There are usually explanations why deaths are not reported. Not all of them lead to erroneous payment. Use your common sense. About 10 billion Like dollars are paid erroneously, that's 1% of the benefits payments. Like here, federal employees are pretty neutral, apolitical. Now musk wants to...

I have a solution for that. Make the interest on national debts payable by the top 1% richest people. They own most of that debt anyway. At present the top 1% earners pay about $1.1trillion, the other 99% pay another $1.1trillion.

It's a political decision, paying welfare, defense , nhs or national debts.

Biden gave to Ukraine about $140bn half in weapons ($66bn), half in cash ($73bn) in grants. European countries gave to Ukraine similar amounts, $53bn in military aids, $73bn in cash. The amount of $350bn that you said half gone missing has not been paid to Ukraine. Biden has only PDA, Ukraine...

If you were Starmer, would you go see Trump this Thursday? Trump: “I want rare earths, oil and everything else we can get from Ukraine”. He also wants the right to licence Ukraine's resources to third party. He basically wants to be paid for all the help Ukraine got from Biden's administration...

Sorry, I should have used my reading glasses.

I can see the problem if the ramp can't lift the van. However, about driving licence, if the van is battery powered, thet get 1 extra metric ton allowance for their battery, the 3.5T becomes 4.25T. Renault Traffic LWB High Roof, unladen weight: 2,498kgs, payload 1086kgs. Gross vehicle weight...

The battery on that video is 4S2P 302WH - with a motor driving the rear wheel directly? I can't see it compete with a normal £300 crank drive motor even if money is no object.

I don't think it will be a problem. we already got 15,000 charging points. More will be added when the market develops. New cars can now have 10%-80% topup charge in 10 minutes. Not many will even need that long because it will invariably cheaper to charge at home. People will book their...

the whole world is getting their BEVs made in China and sell on design and software. Why reinvent the wheel and make life more difficult for ourselves ? China already makes Tesla cars for the whole world except Trump's homeland. Honda and Toyota do the same.
