I’m on my way to Cleveland today (as if you couldn’t tell) for a one-nighter business trip. Check in wid’ ya when my feet touch ground again.
Cheap Thoughts: Rock And Roll Hall of Fame
Why is the Rock and Roll Hall of Fame building made of glass? Shouldn’t it be made of … rock?
Chernobyl
A thunderstorm knocked out our power Sunday night. In spite of knowing better, we kept mindlessly flipping light switches. Electricity is ingrained into our lifestyle. Its not easily given up. As long as we live with electricity, we must live with power plants. And as long as we must have power plants, we must choose between:
- coal, which scars the landscape and produces acid rain
- oil, which rely on scarce oil from unstable regions
- natural gas, which has the same issues as oil but at least burns cleanly
- solar, which take up lots of real estate don’t come close to offering enough capacity
- wind, which have the same issues as solar and only work in few locations
- hydroelectric, which drastically affect the flow of rivers and the life that depends on them, and
- nuclear, which is usually safe. Except when its not, in which case it becomes a monster.
Like it was one morning twenty years ago.
It was twenty years ago that an early-morning emergency drill backfired at Chernobyl, causing Reactor Number 4 to explode and release deadly radioactive steam and debris across the landscape. To paraphrase the late, Nobel-Prize winning physicist Andrei Sakhrov, we still don’t quite have a handle on the powerful forces we have brought into existence.
Twenty years have passed. Chernobyl will be a wasteland for many hundreds more. How have we progressed since? When we reach for the light switch, we expect something on the other end to be pushing out electrons. Is it worth another Chernobyl to keep our beloved elecricity? Are we willing to live in a world without electricity? If not, what’s next?
[I’m currently reading The Truth About Chernobyl by Gregori Medvedev, former chief engineer at Chernobyl. It brings back the same fear I felt in 1986 when I heard the scary news of the plant explosion. Also, see my earlier post on Three Mile Island.]
Electric Cars, Unplugged
Oil prices have gone through the roof lately with no signs of slowing down. With this in mind, and having the itch to try something new, I’ve been exploring the option of buying an electric car. I figure hybrids only take you halfway there. Why not go completely electric?
I read about electric cars in the latest issue of Make magazine, though these were hobbyists’ cars. I don’t have time to build one, so it was time to look for a complete car. Some asking around brought me to the Triangle Electric Automobile Association club, a local group of electric car enthusiasts. A notice on their webpage told me an electric car owned by the late Jon Mauney was for sale. I made an appointment to see it.
The car is in the posession of Ken, one of the club’s members. He’s been sheperding it for the past two years, as the car hasn’t been exactly well. I met him at home and got a look at the car after work today.
The car is no thing of beauty, to say the least. It’s plastered bumper to bumper with graphics advertising the EV Challenge, a high school competition for building electric cars. The car was covered in dust and pollen as well. It hasn’t moved much in the past two years.
Ken popped the hood for me. I peered at a bewildering assembly of strange boxes and cables. Toto, we’re not in Kansas anymore! A large silver box took the place of the engine: a control unit which powered the electric motor. Surrounding the control box were other boxes as well as familiar parts like power steering pumps, an air conditoner, and radiator. There were more parts hidden beneath the control box, including the motor itself.
As we climbed into the dusty car a smell of mold wafted out. I checked the window seals and, sure enough, they were loose. Electric or not, there’s no getting around the fact that the car is twelve years old. I sat in the passenger seat while Ken “cranked” it up.
“Purring like a kitten, Ken!” laughed a neighbor as she walked into the house. There was a purr of sorts, though not from pistons firing. A slight buzz emanated from under the hood – the power steering pump. Not much noise, otherwise. We backed smoothly down the driveway and took a spin around the neighborhood.
As we drive, Ken explained the main issue with the car. “When it works,” he said, “it works great. Only there’s this problem.”
“Oh?”
“You’ll be driving along and all of a sudden the motor will stop.”
“I see.” Houston, we have a problem.
Ken explained his theory that the battery pack was sliding around underneath the car, causing a short in the system. I listened with interest until he turned the driving over to me.
The car handled very solidly. The battery pack underneath the car kept the center of gravity lower than most cars, which I could feel in the steering. It drove smoothly and silently around the hills of Ken’s neighborhood, even packing a surprising amount of power.
I was almost willing to ignore the occasional hiccup when I rounded a corner at the top of a hill. Looking down, the dashboard flashed “ready” and “fault.” The accelerator pedal had no effect. The electric car had done the equivalent of stalling: a fault somewhere had stopped it cold.
“Don’t worry,” said Ken. “Usually all you have to do is turn the key off and on again and it will clear up.”
I tried that to no avail. I grinned at him. “Okay, what do we do now?”
Ken hopped out of the car and pushed it for a few yards until the momentum carried it to the top of the hill. He then hopped inside. The plan was to take a turn at the bottom of the hill that would shift the battery pack in the other direction.
Ken’s wife came to rescue us, a role she seemed to have played before (and regretted). The car was left for AAA to deal with. On the way back I asked Ken why the Triangle EAA clubmembers didn’t buy it and fix it.
“That’s a good question,” Ken answered, trailing off.
I learned something important from the experience. Most importantly, electric cars are great when they work, but when they don’t, don’t count on calling your local mechanic. If you can’t fix it yourself, it ain’t gettin’ fixed. The particular car – a converted Geo Prizm – isn’t made anymore. The conversion company went out of business long ago. There’s only your own ingenuity and that of hundreds of electric car enthusiasts to get you going again.
In spite of the issues with this car, I am still enamored with owning an electric car. Perhaps when the right one comes along. At this point in my life, though, I’m not ready to make my car my hobby. For now, electric cars seem to be stuck in first gear.
Blogger’s Battle
Dang, I hate it when I think of a fantastic topic to write about and then I don’t have time to write about it! Day job, you know. This one will take a few dayss to write and research so it’ll have to wait until later.
For now, nibble on some Mickey D’s.
Why I Don’t Use Google Maps
Google Maps is great for its pretty satellite pictures, but for finding you way from one place to another it sucks. Part of my confusion in getting to my customer site in Boston Monday was due to using Google Maps over Mapquest. I’ll never make that mistake again!
This morning I decided to see how to get from Raleigh to Knoxville. One would think that I-40 would be the way to go, but then one would be wrong. Google Maps gives you a scenic, meandering trip through Virginia before heading southwest towards Knoxville.
Attention, Google: the West has long been settled! There’s no need to detour around the Appalachian Mountains. Believe it or not, there are now roads< which go through them. You no longer need pack mules or to go it on foot to go west. Lewis and Clark have done all the dirty work for you, hundreds of years ago.
Only Lewis and Clark did a far better job.
WalkAmerica: Thanks For Donating!
We’re down to the last 24 hours for donating to the March of Dimes’ WalkAmerica. Thanks to everyone who donated this year. Shout outs go especially to Woody and Wade, who not only donated but pitched us on his blog, too. You rock, Wade! Thanks!
Tomorrow the family and I will be at Nortel’s campus in RTP with thousands of other festive volunteers to take the walk. If you’d like to join in on the fun, drop us a line, or just look for us there.
We thank you and thousands of preemie babies and their families thank you, too.
Maker’s Mark
I bought my first copy of Make magazine this weekend after first checking it out at Linuxworld a few weeks back. Let me tell you, if there was ever a magazine produced just for me, this is it! It’s a fat quarterly magazine filled with do-it-yourself (DIY) projects, some of which push the boundaries of what you thought was possible. I used to read Nuts and Volts for this kind of thing, but Make blows it away.
A sample of this issue’s highlights: an interview with Woody Norris, the wizard of untrasonic sound and inventer extraordinaire; a profile of DIY electric cars and the tinkerers who built them; a primer on Free to Air (FTA) digital satellite television; engines you can make out of Coke cans; and much, MUCH more! If the TV genius crimefighter MacGyver ever subscribed to a magazine, it is Make.
This weekend the magazine is sponsoring the Maker’s Faire at the San Mateo County Fairgrounds in California. The two-day family event will feature exhibits on DIY antenna building, electronic recycling, hardware hacking and tinkering. Television’s most famous makers (well after MacGyver, of course) the Mythbusters will also be at the Faire. If you’re in the area, the Faire is a must-see. It reminds me of Bob Young’s Lulu Tech Circus, only better focused on the DIY crowd. Perhaps Bob’s idea wasn’t so crazy after all.
I’m already sorting through my cool project ideas to see if any are Make-worthy. I might get an article published yet!
Back From Boston
I’m back from my day trip to Boston. I landed there Monday morning around 10:05, well ahead of schedule. I had two hours to meet my customer, so I was thinking I was in good shape.
I was wrong. I got on the Mass Turnpike heading west when I decided to stop and check my directions. Dumb move! Turnpikes don’t easily let you back on, so I decided to see how far Route 16 took me.
As I’m driving along, I pass groups of schoolkids on the sidewalks. There were balloons tied to fences. People were sitting out on their porch steps. Planes trailing banners competed for space with F-15 Eagles flying overhead.
“Hmm,” I thought. “Must be something going on.”
That something, I soon discovered, was the Boston Marathon!
Now that I was off the beaten path of I-90 I was doomed. Roadblocks were everywhere. New England can be confusing enough to navigate without having to backtrack several miles to get around a race course. I found my way to Route 9, which took me up to 495. From there, I missed my turn and had to backtrack to 495, which thwarted me again since the exits I wanted to use to turn around were blocked by police for the race.
I wound up at the customer’s site a half hour late. Fortunately we had a good laugh about it.
I did my thing there and got back to the airport early with an eye on getting an early flight back. I was the fifth standby for four empty seats. D’oh! Oh well, at least my Boingo account got me on the Internet.
I did manage to get home in time to tell the kids goodnight, which was the highlight of my day. As much as I hate leaving the family I have a number of trips lined up for the near future.
Whatever happened to life slowing down?
Boston
I’m heading to Boston for the day after a fun and full Easter weekend. More details when I get a chance.
