Without humans sending great gobs of CO2 into the atmosphere the climate at this point would be starting to tip into another ice age. So, yes, all scientifically aware humans agree that the current cause of climate change is human induced. It can be argued though that warming is better than freezing. Personally, I expect say 100 years from now when warming is on the wane we'll start burning fossil fuels just to avoid an ice age. But in the mean time CO2 is a bad thing. The golden mean is what we are seeking.
Cybertruck was not love at first sight for me. But after 24 hrs I signed up because of the value. 4x4, adjustable suspension, locking bed, 240v, pneumatic air and much more for $50k. Plus the usual no gas bill and very low maintenance. It's a deal.
But you're mistaken. The Cybertruck has none of those features, since it doesn't exist. It's entirely vaporware. When they start shipping them -- if that ever happens -- then you can list what features it has, and what they charge for them.
But what you bought into, and paid your $100 reservation fee for, does not exist.
Tesla does have a track record of delivering things however. It is not as if they are a complete unknown. I think it is reasonably safe to assume that it will exist eventually.
In 2020 the Netherlands bought more ebikes than pedal bikes for the first time. They also paid on average $2000 for their ebikes compared with $1000 for their pedal bikes. So in terms of dollars (or Euros) the market in the Netherlands is now 66% ebikes.
What people in the Netherlands found was that an ebike would allow them to do errands up to a distance of about 15km whereas with a pedal bike the distance was more like 5km before they would take their car.
My experience is similar. Ebikes in practice are more like a smaller car than they are like a bigger bike, when the roads or bike paths are suitable.
"American" or "Association" football ? (Ironically, FA-aka-soccer fields do not have a standard size, only standard boundaries, so they would not be a valid unit of length anyway...)
I used an American football field, and only the length, and my math could be off. When I read “X football fields long” I assume American football, and when I read “X football pitches long” I assume Association football. Or at least I would have, if I had ever encountered it.
“Football field” as a standard is, I believe, based on American football. Which is odd, because American football is non-migratory.
If it's safe to ship tons of LNG on big ships there's almost certainly a way to ship batteries safely. It might take a few 'incidents' though before best practise becomes clear.
In a similar direction, I was thinking of the zillions of gallons of petroleum products that have accidentally ended up in ecosystems during transport.
One data point. I have had difficult to control plaque for at least two decades. According to my dentist others have continuing problems with cavities. I don't.
For the past three years I've used an Oral B electric toothbrush without any improvement.
And then last January I made two changes that have made a huge change in my plaque situation (verified by my hygenist of three years).
First I upgraded my electric toothbrush to the Oral B 4000, which has noticeably more power, at Christmas. And second I changed my brushing technique. Instead of brushing flat against my teeth I now brush the gum line at my teeth and rotate the brush head to a 45 degree angle down at the gums. I then move the tooth brush back and forth over sections of teeth. Typically side or front though the backs if the front teeth require a slightly different approach.
After these changes my hygenist noticed a big improvement in my gums. I also reduced my flossing but when I do floss now theres very little pain, bleeding or swelling unlike before.
Your mileage may very but if you have plaque problems you might save on hygenists.
This is an excellent anecdote for exactly why we are building Bristle. We're finding more and more that oral health is not a one-size fits all. I'm glad you've been able to find something that works for you.
If you look closely at the data from the blog, there are flossing "responders" and "non-responders". I'll have some follow-up data published about this soon, but we've been able to define oral microbiome archetypes that we're using to predict which oral health regimens may actually work for you. There are some people who never floss and still never get gum disease or caries, and unfortunately some who do everything they can with no improvement.
