EV Q&A

February 8th, 2010

I’m not sure why Hasso Hering has it out for EVs, but he clearly does. In a recent editorial asking if “we can handle electric cars”, he complains about the fact that the political response is more study: “You get the drift: More committees, more initiatives, more studies, more big words.”

Then he turns around and suggests that we need a bunch of answers to questions about EVs.

You can’t have it both ways.

Perhaps I can help him, however, having been driving an EV here in Corvallis for nearly 4 years, and in Portland for a year or two previous to that:

Q: Suppose I get an electric vehicle for quick trips around town, but if that’s the only vehicle I can afford, how do I make trips of more than 100 miles or so?

A: If that’s the only vehicle you can afford, you can get a plugable hybrid (e.g. the Chevy Volt coming out late this year), you rent an ICE (Internal Combustion Engine) car, or you will just have to wait for technology to improve, which it is doing at a phenomenal rate at the moment. Low end and/or used EVs suitable for low speed city driving can be had relatively inexpensively however.

Q: If ODOT puts in charging stations at all the rest areas on the freeway, how long do I have to wait around there for a charge to be complete so I can continue on my way?

A: That is one of the areas where technology is improving and a key factor for pure EV technology to become viable as an exclusive transportation means. Because we’re not there yet doesn’t mean we shouldn’t be planning for it and taking the first steps, particularly as it’s useful for hybrid technology in the interim. Even so, the Nissan Leaf, coming out in a couple of years (and in limited rollouts sooner) is supposed to do an 80% charge in half an hour. Not ideal, but not unmanageable either.

Q: How would they handle congestion at public charging stations if even 10 percent of the traffic runs on battery power and each charging session takes, say, an hour or two?

A: That is indeed something that is going to have to be addressed, but doesn’t seem like a gating factor when you consider that, unlike liquid fueled cars, you don’t *have* to gas up at a public station. Most EVs will be “fueled” at the destination and only cross country trips will require “gas stations”. I would expect that in cities, parking meters will become charging stations where you pay for a charge and your parking space at the same time. The amount of electricity needed is so low that the cost of the charging station is likely dominate the parking charge, and I would expect build-out to ramp up to meet demand. People will likely often choose to wait until they get home to charge, reducing the problem.

Q: What happens to electric vehicles that get caught in tie-ups on the freeway, the kind where you can’t turn off the engine but have to spend an hour or so moving ahead a few feet at a time?

A: Electric motors don’t work like ICE: if you’re not moving, they’re not consuming power, and they don’t consume very much at all when moving slowly. Stop and go traffic is very EV friendly, however unfriendly it is to the passengers.

Q: If these kinds of considerations make it impractical or unlikely that households could rely on electric vehicles alone, how could most people afford an additional rig for just short errands around town?

A: How many families have two (or more) cars already? A large percentage I’d wager. And I’d also wager that it’s a rare thing where all need to be long range vehicles. Reset your trip meter first thing in the morning, just after noting the value for the previous day’s ventures. That’s your worst case, not counting “opportunity charging” options, range requirement. Particularly in Corvallis, it’s just not going to be an issue. My EV is particularly short ranged, and I’ve had to switch to my ICE maybe twice in the 4 years I’ve been here (and at least once was more for comfort than need), and the only time I drive my ICE otherwise is when I’m leaving town.

Q: If they can afford them, where would the extra vehicles be parked, since the garages are already full with the cars they have and can’t do without?

A: How many people actually put cars in their garages as it is? Really, if that were the biggest problem we had to worry about, gas would already be history. Countering misinformation is a far bigger problem.

Of Bagels and Breadsticks

February 6th, 2010

People make altogether too much of human preferences, trying to pigeonhole and judge them, yet the simple fact is we’re just not that simple: while you may prefer bagels to breadsticks, that doesn’t mean you can’t enjoy a breadstick once in a while, especially if that’s what happens to be available, and vica versa. Some may have a strong preference for one or the other, even to the point of disgust at the thought, yet some may find them both equally tasty. Some may have a genetic difference in their taste buds predisposing them one way or the other, but factors in the environment will have an influence as well. Preferences may even vary to some degree over time. It doesn’t really matter which you prefer (if you even have a preference), particularly when there is a vast oversupply of both, yet a lot of people seem to have this strange notion that if your preference isn’t for the one they think is “right”, you’re evil and undeserving of being treated the same as the ones who do. I really don’t understand why it’s such a big deal — c’mon people: it’s just a breadstick!

Thoughts on Economic Stimulus

January 10th, 2010

The Wall Street Journal posted an article on Jan 8 positing that
Government Spending Does Not Stimulate Economic Growth.

After thinking about it for a while, I think the author is taking too simplistic an approach to the question. In the long term, he’s right: the money the government is taking comes from somewhere, but when you look at how stocks and bonds work, the effect of government stimulus is not to take money from Paul to pay Peter, but in the devaluation of the stocks and bonds sold to buy into treasuries. Stocks and bonds are kind of like a financial “potential energy” storage pool: aside from the initial sale by an entity to fund some endeavor, the buying and selling of them does nothing for the economy, just shuffling assets around, until an investor cashes some out to spend. That is not without value, but in terms of short term economic stimulus a minor devaluation has little impact relative to actually getting cash into people’s hands to keep fueling a stalling economy, which would certainly devalue stocks and bonds dramatically, as was recently demonstrated.

Repaying the bonds will be a future drag on the economy, but if the stimulus is successful, there will be enough headroom to cover it. To some extent, it even should act to counter an exuberant rebound, smoothing things out.

Hawaii, Day 10: Homeward Bound

June 7th, 2009

That’s it for the pictures, Sunday morning I packed up and flew home. It was a great trip and it was great to see Chris and his family again, and I’ll be back soon!

Hawaii, Day 9: Reefdancer

June 6th, 2009

On Saturday, I took Chris and Ohia on the Reefdancer (Monique and Tree didn’t want to go or had something else to do). It is a boat that has the passengers down below the waterline with bigger windows than you get in a sub, and most all the fish are in the upper waters anyhow. As it turned out, the windows were still smaller and lower than I would have liked, though they’re perfect for kids, but it was a fun trip even so…

Hawaii, Day 8: Around Hilo

June 5th, 2009

I had an afternoon flight back to Maui on Friday, so that Chris could pick me up on his way back home after work, and so I could do more sightseeing on the big island…

Hawaii, Day 7: Lava Viewing Boat Tour

June 4th, 2009

While in passing through Kalapana the day before, I saw a sign for a boat tour out to where the lava enters the ocean. I thought, “that sounds like fun!” I wasn’t really expecting to get very close, but love the water and thought it might be cheaper than the helicopter ride I’d been planning (not a lot as it turned out). I looked around online when I got back and found another one that looked a little more real, though it was a toss up — the sign I’d seen looked like it was native locals, which I wanted to support, but I decided to go with the other one. It turned out to be one of the best tours I’ve ever done! (Lava Ocean Adventures).

Hawaii, Day 6: Kilauea

June 3rd, 2009

Wednesday! Time to see the Volcano! The first time I was here, in 1998, I did a lot of hiking around up on Kilauea, but never got to see the actual lava. I hoped to change that this time, trying to be more prepared, but also staying near the “county viewing area”. It turns out you still can’t really get very close, but it was cool anyhow (and tomorrow blew it all away!)

Hawaii, Day 5: Atlantis to Absolute Paradise

June 2nd, 2009

On Tuesday, I decided to go ahead and do the sub tour again, forgetting how little you can actually see. Then met Chris for lunch and he dropped me off at the airport for the flight to the Big Island, where I was going for a couple days to see the volcano.

Hawaii, Day 4: Hookipa, Little Beach

June 1st, 2009

Chris worked during the week, so Monday was my opportunity to spend the day at the beaches. Chris didn’t want to leave his car parked at the Big Beach parking lot, as it has a history of breakins, so I spent the morning sightseeing, met him for lunch, and then he dropped me off at Big Beach, then picked me up after work. From there, I made the short trek to Little Beach and spent the afternoon…
