November EV (and FCV) musings

It’s been a busy month — busy enough that though one in seven Canadians crossed the border for Black Friday, I wasn’t one of them. (Like a further one in three Canadians, I did my shopping online. Bought me some books — and by books, I mean books so nerdy Aya will despair for Leo’s future social skills.  ;)  )

Seriously, more Canadians expected to participate in Black Friday, than voted in the last federal election. This is how dark ages begin!!  ;)

On the EV side, I wrote a few pieces for GreenCarReports, though I wasn’t able to write something on BMW’s i3, which made me rethink fuel cell vehicles.

Basically, the i3 is an electric car with a 30-horsepower (25 kW) motorcycle engine strapped to it, to provide a bit more range.

If someone were to design a fuel cell car with a big enough battery to soak up all the relevant incentives, and strap on a 25 kW fuel cell stack for extra range, I wonder if that would be a way to drive FCV adoption?

You’d save money because the stack would be a lot smaller, and you could use one hydrogen fuel tank instead of two. (Since the super-high-pressure fuel tank is about the only component that isn’t used in other fuel cell applications, I’m guessing it’s a cost barrier.) Better still, the stack wouldn’t have to last nearly as long (maybe 2000 hours instead of 5000 hours) because it’d only be in use part of the time, which allows it to become cheaper still. (Adding durability costs money.)

The fact that you’d run 50%+ of the time on electricity would also circumvent the hydrogen infrastructure issue. If there are only a handful of hydrogen stations in town, and you know you’d have to refuel every couple weeks, you might be reluctant to buy a fuel cell car because of the inconvenience.

But if you mainly run off electricity, you might only need to refuel your hydrogen tank every couple months — and taking an occasional detour to refuel six times a year, probably isn’t that big of a deal for most people. That’s once per season, and maybe the dealership tops you up when you go in for your twice-yearly checkup.

So, in a word, I think a fuel-cell based i3 type vehicle (mainly electric, but using the fuel cell as a range extender) would accelerate adoption. As it turns out, the French postal service is investigating just such a fuel cell “range extender” solution.

Ah, it’s nice to be able to muse about these things, now that I’m not in danger of spilling any confidential info. Heck, I can even poke around patent records in exactly the way I was discouraged from doing!  ;)

As for my GreenCarReports contributions:

– I had a chance to practise my French a bit (and practise using Google Translate a lot more) when summarizing how the Quebec government really raised the bar in support of electric vehicles. Nice what you can achieve with minority governments who’re rather desperate to stay in power. ;)

– I did a boilerplate Canadian sales stats piece, and a more interesting one on WWF Canada’s take on the country’s electric vehicle progress.

– I also had a chance to write up some nifty apps — one from a cool Waterloo company — which can help people save money on gas, and/or choose more fuel efficient cars. Next time any of you buy a new car, ask if the dealership has the MyCarma dongle!

Note: they didn’t pay me to say that, but on the subject of getting paid, the Paypal transaction for my articles ran into the… double digits. Yep, there’re a lot more zeroes in engineering paycheques…  :)

Lastly, I saw my first reference to Fox News’ annual post-Thanksgiving “War on Christmas” coverage the other day, so put together a little post explaining how the first people to write Christmas as Xmas were, well, medieval Christians. And they did so because in Greek, Christ is spelled with an “X” (it provides the “Ch” sound). If anything, the use of Xmas points that faith’s faithful back to those first Greek-speaking communities who heard the Christian gospel preached — and I would imagine that would be a positive, not a negative thing. *

It all reminds me of a time in the mists of fuel cell years past, when I asked a colleague to give me a refresher on a particular piece of equipment. He was strangely reluctant, so I popped back to my desk and printed up the work instructions — only to find that I’d actually written them, years before.  :)

– – – – – –

* amusingly enough, abbreviations are actually a key tool for establishing that, while it took about 350 years for Christians to agree on what books went into the New Testament, the eventual winners of the battle-royal between Christian sects pretty much used the same edition after about 150 AD. (The ecumentically curious can go here for further reading.)

The person who composed this edition used a very particular set of abbreviations for key words — God, Jesus, etc. — which were faithfully copied in pretty much every orthodox text thereafter. These abbreviations don’t appear in the scraps of heretical texts we’ve found, so we know those texts belonged to different groups of worshippers.

Sadly, we only have scraps of those texts, because soon after the canon was officially settled, disapproved writings were put to use as kindling, as they so often are. And while that represents a literary / philosophical / theological loss, as an engineer who really loves curating and standardizing documentation sets, a very, very small part of me kind of knows where those book-burners were coming from…  ;)

Putting the “X” back in Xmas

Xtians began using “Xmas” 500 years ago, since in Greek, X is the “Ch” in Christ

Around the holidays, some people (not to name names or anything) urge modern society to put the “Christ” back in Christmas. There’s much to criticize about the hollow vacuousness of consumer culture, after all. Most of us can buy into the idea of better treasuring time with family and friends; and who’d oppose charity and compassion for the less-fortunate? (Well, apart from that strangest of philosophical tribes, the Objectivists, that is…)

Heck, the leftists among us might even be open to the Christian idea of a 100% marginal tax rate, on assets — that whole “tithing” thing is so Old Testament ;) – which is backed up by the fact that Jesus’ early followers were basically communists! (Admittedly, it’s easy to give up private property rights when you think the world’s about to end…)

Unfortunately, some misguided folks want to put the “Christ” back in Christmas, because they think “Xmas” is a part of some sort of secular war on Christmas. If there’s any upside to this, it’s that secular humanists are the new scapegoats of Christian demagogues. After nineteen hundred years, the Jews finally, finally catch a break! Hallelujah!  :)

In Greek, “Christ” is spelled with an X

This is all very strange, since it was Christians who started using “Xmas” in the first place. Five hundred years ago. And followers of the faith used X (and/or Xp) as an abbreviation for Christ, an additional twelve hundred years before that.

They did so because the Greek word for Christ — Χριστος — starts with the Greek letter chi, which happens to look like an “X”. And Greek is the language in which the first Christian scriptures were written, and in which the faith was first widely proselytized. (To be rigorously accurate, some portions – the Lord’s Prayer and various figures of speech – seem to’ve originally been Aramaic.)

So the real question is why these commentators would want to take the “X” out of Xmas; for today’s Christians, its presence would visually affirm a continuity with the Greek-speaking communities where Jesus’ gospel was first preached, two thousand years ago, and where the religion’s scriptures were written. How cool is that?

Orthopraxy vs. orthodoxy

I do wonder of why Buddhists, Hindus and others just don’t seem to get as worked up about these kinds of things. And my impression could just be because I’m less familiar with demagogues from those traditions.

Still, I get the sense that in eastern traditions, anger and outrage are regarded as unhelpful, if not outright harmful. For all the crimes of the Chinese government against Tibetans in the past half-century, exiled Tibetan Buddhist monks don’t seem to have an “anger button”; they tend to express their distress and condemnation in astonishingly measured tones.

One difference between the major western Abrahamic faiths and the big eastern Dharmic faiths, is that the latter tend to be orthopraxies – they emphasize correct practice – while the western ones tend to be orthodoxies, emphasizing correct belief. I can’t help thinking that may have something to do with it.

If one has adopted a set of spiritual beliefs – an orthodoxy – there’s always the risk that new scientific knowledge could undermine them. Learning that the universe is billions and not thousands of years old could cause a fight-or-flight response in some people, leading to the bellicose annoyance and self-righteous indignation so commonly heard in the words of some conservative religious leaders. Especially if they think such beliefs are all that separate us from the nightmare of Hobbesian anarchy – an unending war of all against all.

But if one has adopted a set of spiritual practices – an orthopraxy – then scientific findings which invalidate their rationale and justification, might be inconsequential. If one is becalmed by meditation, and it seems to serve one’s community, so what if the universe is fourteen billion instead of one hundred and fifty five trillion years old?

Even so, there’s no doubt there are Buddhist and Hindu demagogues, just waiting for the chance to corrode the public discourse in their own home countries, as religious conservatives have done over here. ;)

It’s probably safest to say that we in the West have simply been lucky enough not to have heard of them, because a Fox News-type empire hasn’t given their televangelism and/or megatemples a worldwide media platform. Yet.
