      Why aren’t electric vehicles fitted with an alternator that can charge the battery while one drives; similar to how a gas engines recharge their batteries? With all the advancement in technology it would seem that they have figured it out and won’t implement it to force people to pay for electricity or my own lack of knowledge on the subject.

      The cost keeps dropping and the specs keep getting better and better, but they seem pretty dangerous, mainly because you have to share the road with cars. Still, for the price of an ultra cheap beater car, less than $2000, you can get an electric vehicle with 50+ miles of range and 30+ mph speeds, that you can fold and carry with one arm (if you're kinda strong).

      I've got a basic one and its great. My only gripe is that I don't feel comfortable locking it up on a public street due to theft, so if I want to scoot to a store, I have to bring the scooter in with me. Would be great to see this mode of travel widely adopted, with some decent infrastructure like rentable lockers and more bike paths that aren't just the shoulder of a street full of cars.

    3. Lockheed Martin teases next generation aircraft

      Recently Lockheed Martin put out a post on social media [1] where they showed a silhouette of a yet-to-be-revealed aircraft. Most people seem to believe it will be the reveal of their entry to the NGAD program [2] (Next Generation Air Dominance).

      While not much is publically known one interesting tidbit is how much it looks like the silhouette of the Testor Corp [3] F-19 [4] model that was released back in the mid 80s. Testor said at the time that the model was based on intelligence (aka leaks) of what would eventually become the F-117.

      Aviation forums in the past have said F-19 model is what they WANTED the F-117 and it does look quite a bit like the Have Blue [5] test craft they built, however, the legend is that they couldn't get the math to work for radar deflection properly at that time due to lack of computational power and ended up with the geometrically simpler F117 design we got.

    4. What were your out-of-warranty Tesla issues?

      Model 3 SR+ about to go out of warranty. Wondering what others have had to fix out-of-pocket since their warranties expired? Under warranty, I’ve had service for: replace front passenger control...

      Model 3 SR+ about to go out of warranty. Wondering what others have had to fix out-of-pocket since their warranties expired?

      Under warranty, I’ve had service for:

      • replace front passenger control arm
      • replace both rear upper suspension links
      • replace touchscreen
      • replace metal tips that are on the charging port
      • replace front passenger seat adjustment switch
      • replace front passenger seat (yes the whole thing)
      • replace the front driver lower camera (twice)
      • resealed both front upper control arm ball joints with urethane
      • replaced rear passenger door trim panel
      • wipers made contact with the hood causing a small gouge in the hood
      • replaced front passenger door handle

      Mind you this was one of the first batch of 2019s so, yeah they had to remediate quite a bit.

    5. I bought an e-mountain bike

      I had often considered an e-bike and whilst I don't consider myself particularly good at cycling I have always enjoyed going on a bike ride.

      I live in a mountainous area and I am overweight and late 50's with arthritis and so cycling was becoming harder for me (I resisted an uphill battle). Cycling has always had health benefits both mental and physical but now it was a struggle.

      I therefore started to look at the different models that were available. My requirements were for a hobby cyclist and enough range for a few hours ride.

      I dont know what it is like elsewhere but blimey they are expensive here in the UK. 1500 - 2000GBP for a base model. So I kept my eyes open for a second hand model and finally picked up an E-MTB for 300GBP which fit none of my criteria.
      A Coyote Edge 650 which was sold by a shop called Halfords here in the UK. 36v rear hub driven and a 7 gear rear cog setup

      i have only ever ridden hybrids or tourers before but MTB's are an eye opener and if they are as much fun without the electrics then I really did miss out on some fun in the past.

      I have now done 500+ miles and it has been nothing but fun. I sometimes only get out for an hour after work but for my head that is usually good enough. I can also get to the top of the mountain and just sit and admire the view then follow the trail back down (and dont tell the wife but I am getting quicker and quicker on that down hill track)

      There is no real point to this other than to share my experience as a first time e cyclist

      Downsides, it is expensive. The e bike, the helmet and gloves can be quite expensive and the bits that you need just in case, pump, water bottle, spare inner tube, glasses for when the sun is low. Also when the battery starts to go that is a huge expense, in my case we are looking 300 to 400GBP.

      On the other side though it has re-opened some routes I haven't done in years, my mental state is a lot better I'm losing weight, and I am having fun. Do you know how many flies you can catch when you are smiling!

      Top tips I have found though is that Ali-Express is awesome for tools and parts and that charity shops (Thrift shops in the US) have been excellent for sportswear, I got some good base layers a while ago and the wife brought me home 2 MuddyFox cycling jerseys the other day, one which had a shops label still in.

      If you are still contemplating whether to get one, do so and then make the time to ride it. You won't regret it.

      p.s. Im not buying Lycra
