February 21, 2018 Wednesday – Driving from Tucson up to Kitt Peak in a Tesla Model S
2018 Southern Arizona and Astronomy
The reason I wanted to charge the Tesla last night at the hotel and not have to drive east for 15 minutes to the Tucson Supercharger is that I want to take the 11AM solar telescope tour at the Kitt Peak National Observatory. It takes an hour and 20 minutes to drive westward from the hotel, so driving east to the Supercharger would be inefficient and wasteful of precious time.
I have breakfast downstairs in the hotel, and I’m on the road by 9AM in my fully-charged Tesla. The Model S uses about triple the energy to climb the 1,200 metre (3,400′) elevation change up the mountain, but there is only about nine miles of actual steep climbing. The Model S still has 120 miles of range by the time I reach the summit.
Since I am so early, I am the only visitor for the telescope tour when I meet the Docent in the Visitor Center. She convinces me that the 2.1 meter observatory tour would be a better choice, since the solar observatory is closed, so all we can do is walk around it on the outside. A Docent-In-Training and a few more people show up before the tour leaves – we all agree to stick with the plan to visit the 2.1 meter telescope.
I take a few photos, but restrict myself to areas of Kitt Peak that I didn’t photograph last year. By 1PM I’m ready to return to Tucson, so I rig up my GoPro Hero 5 Black as a dash cam and drive down the mountain and along the highways back to the hotel. The Tesla gains about 25 miles of range due to the regeneration on the way down the mountain road, so I still have just over 100 miles of range after arriving at the hotel. Since the staff have left the Tesla Destination chargers powered up, I plug in for about four hours to top up the charge for tomorrow’s adventures.
