Last weekend, my girlfriend and I drove down to attend the Monte Vista Sandhill Crane Festival. It's a roughly 4 hour/200 mile drive from Denver down to Monte Vista, with lots of variation in elevation. I got a Tesla Model Y last June, and since then haven't really had the chance to go out into the remote mountains of Colorado with it.

This weekend would be my first such excursion. Getting down to Monte Vista is absolutely no problem. At about the halfway point in the trip, there's a Tesla Supercharger. That, combined with the range of the car meant that conserving battery was no problem at all.

I was worried, however, about how the car would fare down in Monte Vista for the three days we would be there for the festival. There are no charging stations of any kind in downtown Monte Vista itself (though there are a couple of slow chargers on the outskirts of town, slow chargers with nothing around them are kind of useless). However, there were fast chargers in the towns nearby! One in Del Norte, and another couple in Alamosa, both a 20 minute drive out of Monte Vista. My plan was to charge up at those every evening while we were down there.

On the trip there, we left Denver at 100% SoC, and the battery and cabin preheated for 30 minutes beforehand. We arrived at the Poncha Springs supercharger with about 17% SoC, plugged in and charged to 90%, which took about 40 minutes. The reason for charging this high was because I wasn't sure what state the non-Tesla fast chargers would be at when we got down to our destination area. My plan was to head from Poncha Springs toward the Del Norte fast charger; arrive at 60% and charge back up to 90% before driving around to look for the cranes.

We arrived in Del Norte at 60% SoC as expected, but we found the one fast charger already occupied when we got there. Thankfully, we waited less than 5 minutes for the owners to get back finish charging, after which I was able to plug in and start charging.

This charger was advertised as a 62 kW charger, but for the hour we spent charging there, the charge rate never went above 30. I'm sure part of this was that I was charging from 60-90%, and part of it was that it was cold out, and the Tesla lacks the ability to precondition the battery en route to non-Tesla fast chargers. We ended up charging there for about an hour to get the same charge that the supercharger gave us in 15-ish minutes.

Luckily, there was a brewery/pizzeria and a neat antique shop just a block away.

At some point in the trip, I became aware through Plugshare that the fast chargers down in Alamosa were being taken down that weekend for upgrades. They were installing more stalls, and I guess that necessitated taking the existing ones offline. Now instead of 3-4 fast charging options in this area, I was down to just one. I was certain that because those chargers were down in Alamosa, many more people would come up to use the single charger in Del Norte. Further, I knew that lots of people came down for the crane festival, and so I was worried that there would be an increase in the number of EVs competing for this one charger.

When we got to our hotel in Monte Vista, I noticed there were outlets near the parking lot. I asked the front desk for permission to charge my car in the lot overnight, but was denied because "it would cost them too much money". I thought about offering to pay for the privilege, but the person at the desk didn't really seem interested in pursuing that line of conversation further.

Overnight, the battery stayed charged at pretty much the same level, only losing 1% indicated charge. We got up at 5 AM in order to see the cranes take off from their roosting location in the wetlands, and go out into the fields to loaf (this is the technical term :D). We spent the rest of the day driving around the back roads and farm roads, watching the cranes in the fields.

The whole day I was checking the charge point app to see if the one fast charger available to us was in use, in order to judge how busy it was, and to plan when we might go charge there. Surprisingly, not once did I see it in use!

Since we had had a great day watching cranes, we decided to leave a day early. We had enough charge to get to the Poncha Springs supercharger, and from there back home with no issues.

I thought I would conclude with a few bullet point takeaways from this trip:

• Range anxiety is real. I spent a lot more time thinking about where to charge and if I could charge enough on this trip
• Being away from the Tesla Supercharger network sucks. A whole set of fast chargers I was relying on was taken down exactly when I needed them. They're slower, you have to worry about them not functioning much more.
• Tesla is opening a supercharger site in Alamosa! They filed for the permit just this week. This will basically erase the anxiety I had last weekend on future trips
• Total energy costs for this 500 mile trip were about $35. That feels pretty cheap to me!

Around 3-5 years ago, Elon Musk was teasing that he thought he had a clever idea for how to make electric-powered aircraft viable/profitable with, basically, current technology ... and he was basically daring people to guess it.

Regardless of what he actually did or didn't know, it got me thinking, and I came up with an idea. I thought I'd run it past the Tildes Team, see if it passes muster.

My idea, in a nutshell, is to build airplanes with only 25%-50% of the battery capacity required for their flight (making them much lighter, with much more capacity for people/cargo) ... combined with, I'll call them Maser Cells on the undersides of the wings ... coupled with low-intensity maser beam emitters at all the major airports.

Airplanes use a ridiculous amount of energy gaining altitude. For short flights, it can be upwards of 50% of their fuel spent just getting from takeoff to cruising altitude. My basic idea is for planes to get up to cruising altitude in large circles over the airport, powered by a combination of battery power and maser energy beamed up from the airport below. Then stay in a taxi-ing circle over the airport until the batteries are fully charged, before departing. Longer flights can plan their route to include one or more detours to pass over other major airports (or other recharging hubs, like the Tesla Supercharging network, but for airplanes) to recharge the batteries along the way.

Trans-oceanic flights would be more challenging, perhaps requiring some kind of recharging hubs located midway in the oceans.

To clarify, my "Maser Cells" are similar to traditional solar-electric power cells, except they are optimized to convert either laser or maser beamed energy into electricity. These things already exist (I forget what they're called), although getting them to a high-efficiency commercial-airline level of production, that would take some effort.

There is, potentially, a lot of inefficiency in the conversion rates, from ground-generated electricity to ground-generated laser/maser, then on the plane, maser converted back to electricity into battery, then from battery into electric engines ... perhaps there are ways to reduce the amount of conversions necessary, or to increase the efficiency of the conversions. Or perhaps this is what kills the idea.

Similarly, if this were actually implemented large-scale, to largely replace fossil-fuel-driven planes, we would be talking about a LOT of electricity requirements, a lot of laser/maser emitters at every airport, and a massive redesign of flight traffic management, to allow for hundreds of planes routinely in hours-long recharging flights over every airport, all the time ... potential choke-points at various recharging hubs (again, similar to what Tesla sees at overly-popular Supercharging stations on the ground) ... and doubtless lots of other issues I'm not thinking of.

Anyway, though, that's the notion.

ETA: This idea could be extrapolated to an extreme degree, with on-board batteries almost completely eliminated.

With clearly defined flight corridors, and ground-based maser power stations located every 10-20 miles along, planes could fly their entire route on power beamed up to them, with only 20-30 minute battery capacity for emergencies.

ETA #2: A person who owned his/her own rocket company might also consider putting the maser cells on the tops of the planes, and launching a bunch of solar-power-generating satellites, with maser emitters shooting power down onto them.

I guess my main point is, if this maser-energy delivery system is even remotely feasible at a commercial level, there's a lot of potential.

What’s up tildorans, This is more of a thought experiment then anything else, is the impact of consuming calories more or less impactful then producing the electricity needed to power the bike? And I also understand this is extremely affected by circumstance. Let’s say you eat beef 3 times a day and live in a part of the world where power is mostly generated via nuclear or hydroelectric. At that point, would the impact via electricity be less then the one via calories? What if you flip the spectrum and you’re a vegan living somewhere that produces all its energy via coal and oil, how does that affect the equation? Thanks
