August 2024

Obviously, there were plenty of goings-on in the U.S. presidential election campaign in August. I’ve talked about that elsewhere, and everybody else is talking about it, so I’ll give it a rest here.

Most frightening and/or depressing story: Human extinction, and our dysfunctional political system’s seeming lack of concern and even active ramping up the risk. We have forgotten how horrible it was last time (and the only time) nuclear weapons were used on cities. Is there any story that could be more frightening and/or depressing to a human?

Most hopeful story: Drugs targeting “GLP-1 receptors” (one brand name is Ozempic) were developed to treat diabetes and obesity, but they may be effective against stroke, heart disease, kidney disease, Parkinson’s, Alzheimer’s, alcoholism, and drug addiction. They may even be miracle anti-aging drugs. But really, it seems like the simple story is that most of us in the modern world are just eating too much and moving our bodies too little, and these drugs might let us get some of the benefits of healthier lifestyles without actually making the effort. Making the effort, or making the effort while turbo-charging the benefits with drugs, might be the better option. Nonetheless, saving lives is saving lives.

Most interesting story, that was not particularly frightening or hopeful, or perhaps was a mixture of both: I did some musing about electric vehicles in August. The hype bubble seems to have burst a bit, as they did not explode onto the international commercial scene as some were hoping/predicting. This is partly because public infrastructure has not kept pace with the private sector due to sheer inertia, but I always detect a whiff of the evil oil/car industry propaganda and political capture behind the scenes. Nonetheless, just as I see happening with computer-driven vehicles, the technology and market will continue to develop after the hype bubble bursts. In a way, this almost starts the clock (5-10-20 years?) for when we can expect the actual commercial transition to occur. It will happen gradually, and one day we will just shrug, accept it, assume we knew it was coming all along, and eventually forget it was any other way. And since I seem to have transportation on the brain, here is a bonus link to my article on high speed trains.

electric vehicle charging in Philadelphia

Here’s an article on the woes of electric vehicle charging in my home city of Philadelphia. On the plus side, electric vehicles are becoming more common.

As of January, there were 6,615 all-electric vehicles and 3,149 plug-in hybrids registered in Philadelphia, according to data from the state Department of Transportation (PennDOT). Combined, those represent 1.3% of the city’s nearly 767,000 registered vehicles. That doesn’t include cars used by the many commuters and visitors who drive into Philly every day.

To fully charge a typical EV on a standard Level 2 charger, the owner may have to leave their car parked there eight hours, which means there need to be more chargers per EV than gas pumps per gas car. 

Yet Philly has only 145 publicly accessible charging stations with 378 charging ports, according to U.S. Department of Energy data. Most of the stations have Level 2 chargers, but 13 of them have Level 3 or DC Fast chargers, which typically charge a car in an hour or less, depending on the vehicle’s battery capacity and other factors. Pennsylvania as a whole has 1,785 public stations with 4,598 ports.

Philadelphia is a large city with many neighborhoods, some quite car-dependent. That is where chargers belong, not in the walkable urban core. What we need there are safe, separated, protected lanes for bicycles and light electric vehicles, like e-bikes and scooters and even light-weight golf carts. These need their own signals and they need to never, ever, ever be in conflict with highway vehicles, whether those are electric or not. So I wouldn’t prioritize chargers there, but on the other hand we should be thinking about air pollution. Replacing fossil-fueled vehicles with electric ones is certainly a win for all the lungs of all the people walking and using those light-weight electric vehicles, so that is one argument in their favor, even in urban cores.

I still autonomous vehicles will eventually solve the charging problem, even in urban cores. Because your vehicle will be able to drop you off at your home or another walkable location, then go park itself somewhere it will not be in the way, then come pick you up again when you need it. So ideally we will be able to have walkable urban cores not ruined by private vehicles, and the ability to take trips to car-dependent locations when we need to. I want to believe this is a decade or less in the future, but it seems to be coming along very slowly.

problems with electric buses

Electric cars might have arrived, technologically speaking, but electric buses are having some problems. The Austin metro area recently committed to going to an all-electric bus fleet, but the early results are that the buses are breaking down and just generally not as reliable as the proven diesel technology. Suppliers are limited, having supply chain issues, and financial problems.

This just sounds like a technology having growing pains in the early implementation stage. Implementation of an emerging technology is a chicken-and-egg problem, where issues need to be solved through “learning by doing”, but if nobody is willing to take the risk to work through those issues the technology never gets scaled up. If you really want it to happen, the federal government might need to share some of the risk in the early stages. Or here’s an idea: pilot the technology with school buses?
