I think people set the max current (using the cable) on the 36v BBS01 to 18 amps which would give you (legally) 650w output power from the controller.

Thanks, interesting article. I think my instinct (as per the article introduction) is that the most likely explanation is (as in SARS and MERS before it) that the virus crossed the species barrier from an intermediate host sold at the wet market but we can't rule out (yet) a lab leak. Although...

Yes, aren't humans 98.9 % genetically identical to chimpanzees. Didn't the book rely on the theory that the “preadaptation” that was needed to make Covid-19 infectious to humans was very suspicious and a sign that it originated in the lab whereas exactly the same adaption had happened...

"The closest previous isolate, RaTG13, came from yet another bat species, R. affinis, living in a cave in Mojiang, in China’s Yunnan province. Its similarity to SARS-CoV-2 is 96.2%—only slightly lower than the BANAL viruses—but the number obscures a profound distinction between the new isolates...

I think you are misreading my referenced article the "so far" means until this research Here is a report on that article https://www.science.org/content/article/close-cousins-sars-cov-2-found-cave-laos-yield-new-clues-about-pandemic-s-origins When SARS-CoV-2 was discovered in early 2020, some...

This is the record from the Mauna Loa Observatory that opened in 1958 But this still seems consistent with his pledge for China emissions to peak before 2030 (some analysts say this has already happened) and be carbon neutral by 2060. They are also building a huge amount of renewables power...

This one ? (this was the first two reviews I came across, but still might be interesting) https://www.telegraph.co.uk/books/what-to-read/viral-alina-chan-matt-ridley-review-pushes-lab-leak-theory-behind/...

The 2019 World Stamp Exhibition was held in Summer of 2019 in the Wuhan International Expo Centre - just think of all the saliva being transferred around

That's probably quite similar to me - I can do trips of about 20 miles and the 20Ah 48V battery drops by about 3-4V , so probably uses just over 25-33% of the battery

I saw what I thought was a very good twitter thread on the Astra Zeneca vaccine

@soundwave how much of your battery does that trip use up ? Is it quite a busy route and you have to stop and start quite a bit or quite quiet ? - how hilly is it ?

Well that is pretty early on , I guess that there has been a lot more research into it since then but I still think "a laboratory escape scenario cannot be excluded" even if it less likely than a zoonotic explanation. The last bit of evidence I can find is from March last year which suggested...

Don't know an awful lot about it but I thought that was the most likely cause ? eta - this was the first scientific article that popped up when I googled covid lab leak vs zoonosis https://journals.asm.org/doi/10.1128/mbio.00583-23

Milankovitch cycles operate over cycles ranging from tens to hundreds of thousands of years not decades

Production emissions does not account for emissions embedded in global trade - China produces emissions for a lot of stuff consumed here (and lots of other countries)

The observed and projected impacts, risks and vulnerabilities are laid out by experts in their fields There seems very much a consensus around this, I can't think of any serious researchers into this area that would dispute the IPCC technical report ...

That's the best sort of gift - something you wouldn't have bought yourself but then realise it's brilliant. I too, am still a bit in awe of e-bikes and how brilliant they are, and you can turn the assist level up or down depending how much exercise you want and how fast you want to go. I saw...

I was interested in where the energy to power a bike goes and the various bike design parameters, not really specific to just electric bikes e.g. 1) weight - at first I was thinking this only really applied to hills, but I'm realising that there are very few completely flat roads and even on a...
