I charged to 100% then left the car in the sun… and didn’t have enough energy to get home…

This is a followup to A road trip with no superchargers? … how did it go?

Tesla full self driving: my experience

Tesla offered a free 30-day trial so I decided to try it out. There were a few things I liked, but overall I don’t think I’d pay for it There were some very confusing moments, a few times when I had no idea what it was doing based on traffic, and it really struggled when it came to construction (which is everywhere!) I can see why there are issues and why governments want to better regulate it. In the end, it was fun and I’m glad they offered to let us try it. But that’s enough for me.

Gas or Electric in cars. Which is cheaper?

I do a calculation to compare $/mile driven for both gas and electric cars? In summary it is very possible that gas could be less expensive (gasp!) if you are stuck using public charging most of the time. Paying 50 cents or more per kWh vs around $3 a gallon is a break even. But as always, your mileage may vary.

The astronaut walk out door at the Kennedy space center

In a cool, longstanding tradition, astronauts all stay in the same dorm as the Apollo astronauts. And as they head to the launch pad, you can see them come through the same door.

Teslas supercharger network: a happy accident

The superchargers look to be a big item, perhaps as high as $20 billion a year. But did you know that a charging network was kind of an afterthought? And now everyone is ready to use it.

Landing on the moon

I look back into history at moon landings, and then talk about our recent attempts - and successes in having unmanned moon landings. And yes, I’m aware that the video I show of JFK was not the one at Rice, but it was a version of the same speech. In the latter part of the video, I spend some time discussing what went wrong with Odysseus and how to possibly avoid it in the future The video "Making a tin foil hat" may be found here:

The idea is great. But in practice? Much harder to say.
