Generating green energy by bike

If you were one of the people following my limited edition miniseries blog Climate Ridin, you know I’ve been obsessed with the concept of generating electricity as I bike to charge up my gear. I tried doing it on the cheap for the 2011 California Climate Ride with a bottle dynamo hooked up (poorly) to a headlight with a battery backup and USB port. You would think a bunch of fellow tree-hugging greenies on bikes would embrace my attempt at alternative energy production, but the ones that commented mostly complained it was too noisy. This was fine because the ferocious resistance the bottle dynamo had on my tire meant I couldn’t keep pace with them to annoy them through the redwoods. The wire leads were also incredibly wonky… For the most part, the only thing reliable about them was the metaphysical certainty that they would pull out of the dynamo connectors every mile or two. Additionally, the current was incredibly inconsistent, which iPhones don’t like (to anthropomorphize an Apple product, which has never been done before). Experiment was over after Day 1, and the dynamo became the problem of the thief who stole my bike a month later.*

So, for 2012 I chose storage over generation: an enormous 12000 mAH battery was enough to charge an iPhone 4 from 0-100% close to three times. It was plenty for the OR/CA trip with MJ (which reminds me… MJ update below), but still required awkward campsite bathroom outlet recharges or extended coffee shop pitstops. When you are sitting on something that can generate power as you pedal, and you’re a tech tool like me… Well, I had to revisit bike-based electrical generation again.

I give you… the dynohub. Forget the old fashioned bottle dynamos… Dynohubs are integrated into your wheel so there’s no more fiddling with tensioners or worrying about friction melting your tires or your generator. Electrons flow with every revolution of the wheel.

That, however is just step 1. You see, most devices are finicky about their electricity. They need those little electrons to come in a particular way or they won’t fire up (or they’ll fry, but that’s another story). Also, because the current coming from a dynohub is necessarily inconsistent (stop, start, go, fast, slow… This all changes the flow), just having a dynohub is not enough to be useful for the gadget charging wannabe. Many lights can hook directly into them, and until recently that was about it.

LightChargerA few crafty manufacturers tapped into the dynohub-as-a-power generator-for-devices idea, most notably Busch and Muller‘s eWerk (love the Germans) and Tout Terrain‘s The Plug and The Plug II: Electric Boogaloo (not really on the electric boogaloo part, but let’s face it: that was a TOTAL missed opportunity). Both devices act as power converters; the eWerk is super sophisticated while The Plug is super elegant. Both were available in Europe only for a while, then found their way stateside last year. I nearly bit on the purchase of The Plug in France, but backed off… Pretty pricey and I wasn’t totally sure I wanted an integrated solution.

As the interest seems to be climbing amongst touring and commuting cyclists, cheaper dynohubs are coming on the market and a few US companies are taking a crack at converters. I found CA-based Bike2Power‘s LightCharge recently and was amazed at how much less expensive it was compared to the European alternatives. Paired with the well-reviewed, but substantially cheaper Sanyo dynohub on a new wheel (thanks eBay seller guy!), what was once a $400+ venture with a SON dynohub and an eWerk dropped to about $150. That was worth the flier…

A few thoughts so far after a yet ride:

it works

– dude, it totally works.

– the connections are standard Shimano connections, so no need to buy anything else. You’ll want to be a little handy with wiring, but by no means do you need to have an engineering degree.

– the LightCharge has a dual switch system that allows for charging either a USB device OR wired lights. I still like my current light system enough as is, so I didn’t hook anything up to that wiring system. Nice to have that option if I change my mind.

– iPhones are finicky beasts. If you slow down to a point where the voltage threshold drops below what the phone needs to charge, it will throw up the dreaded “this device isn’t made to charge me” alert and seems to refuse to charge. I say seems because I believe a speed up will resume the charge, but the charging indicator doesn’t come back – so it’s hard to know for sure. I found switching the LightCharge from USB to lights and back again at speed reset things, as evidenced by the ever pleasant “hey I’m charging!” bleep coming from the iPhone.

– I plan on acquiring a USB chargeable battery to act as a power sink rather than directly charge the phone. This way I know every rotation of the wheel will be converted into energy I can use later. It also gives some charging flexibility for other devices that can hook into the battery, plus if there’s an issue I’d rather fry a battery than a phone.

iPhone charging from dynamo

– Security is a bit of an issue. Dynohubs are obvious to a thief that knows what he’s looking for. I’m considering a Pitlock combined with a cable lock for the wheels. The LightCharge is the thing I may need to leave exposed. It’s possible to remove every time, but it would be a pain. I may consider splicing the line up by the main device and putting in plug connections so I can unplug and leave just the wiring, but that might be more trouble than it’s worth. I’m open to thoughts on that.

– I went with a cheaper option, so it’s entirely possible the hub or the LightCharge could die on me sooner than a higher priced component. We’ll see. The Sanyo gets consistently great reviews (see here, for example) and although the LightCharge doesn’t have the same volume of reviews, I haven’t found one that says it sucks. So there’s that.

– unlimited juice means I can run battery sucking GPS apps and stream audio like a fool. If I have a signal, I can do a whole hell of a lot more on tours now.

Basically, it rocks. Looking forward to testing it for real this winter.

Quick MJ update… MJ’s off to greener pastures in San Francisco come January. The good news is I’m sure we’ll ride together again on tour… The bad is our rides will be far less frequent. We both started bike touring about the same time, and if I’ve learned one thing it’s that you may separate from the people you cross paths with on tour, but you oddly tend to find them again down the road. I think the same will be true with the mysterious one. Also, I think he’ll probably let me crash at his place, and I love me some San Francisco.

Happy holidays… I’m taking a week off between Christmas and New Years so maybe I’ll write another stupid long post that week too.

Two big trips for 2013

As this year is winding down, I’m looking at a couple of big adventures in 2013…

– Some kind of January or early February thing. I pulled the trigger on an ill-fated plan to bike the Florida Keys until I found the camping was totally booked or outrageously expensive. So that’s scrapped. I’m now toying with an Arizona loop starting and ending in Tucson (might be too cold) or a Portland trip that is more about snowshoeing and urban biking. I suspect it may rain.

– The bigger deal is my summer. I have about 6 weeks to play with following WDS in Portland, so I know things start there. Option one is a loop from PDX to Seattle to visit friends and family, then a turn south to San Francisco, and then a return to PDX. Option two is bike east…. as far as I can… in 6 weeks. I thought this might be the year I could do a full cross country tour, but it’s just not enough time if I want to try to sneak in some work and keep the pace reasonable.

So, that’s the deal. I’ll probably overthink both options for both trips and I’ll likely write about the thought process. Apologies in advance.

In other news, I tried to convert my dog Louis into a bike touring dog. It did not go well:

I repair iPads*

*but Jony Ive would cry if he saw what the finished product looks like.

I stepped on my iPad in France and crushed the glass digitizer this summer. Luckily, thanks to the brilliance of Corning, NY’s own Corning glass, that stuff is strong. Other than the ugly break pattern, the iPad continued to work…

…until I dropped it again. Then it started acting like I was constantly pressing on a seemingly random spot on the shattered screen. It was time to act.

I found an amazing local business that would come to you, replace your screen while you wait and send you off with a perfect iPad or a mere $199. But I decided I wanted to do it myself for 40 bucks and a few hours of my time.

I won’t bore you with details, BUT… I’m clearly an electronic genius. A few YouTube videos to light the way, a glass kit from Amazon via some place in Jersey and I’m tapping out this post on a totally functioning iPad with its new screen.

But I’m too chicken to glue the screen down. There’s literally no way I trust that this can work long term without some itty bitty circuit coming undone in there, so instead of making he final seal in the perfect fit and finish of an Apple product, the screen’s locked down with easily removable electrical tape. Black bezel and black tape camouflages it ok:

See it? Jony Ive would. But only when he wiped away his tears…

So, I humbly declare that I fix iPad screens!

I hate to say it, but iOS 6 Maps sucks (right now)

The ATL in iOS MapsI’m not a hater by nature… I really rebel against the trite negativity, particularly put out by vast stretches of the tech and political press (which I happen to read a lot, despite my professed rebellion). That said…

iOS 6’s Maps app just doesn’t work right now. It kinda sucks here in October 2012.

I didn’t have too many problems in DC or WV (the places I split my time) but on a quick weekend trip to Atlanta, the Maps app showed how being a little off can be really bad. Essentially every single trip I had… Airport to hotel, hotel to wedding reception location, back to hotel, then hotel to breakfast spot the next morning… all of them were off by a little bit. A turn here or there, an address off by a block. It all added up to a big mess when you’re in a place you’re not familiar and you’re banking on the data behind the app to work.

So, let me be a little more refined than shake my fist at the sky and declare suckage… the app is slick. Siri… well, she can direct you. But the underlying data is smelly, stinky, sucky. Google Maps was far from perfect, and was clearly missing turn by turn directions in iOS, but I don’t remember the consistency of misses like I just experienced in the new Maps app.

But… it’ll get better. I can use Waze or any number of other options until the underlying data mess gets fixed.

And by the way… Atlanta? You keep staying weird. We like that:

Update… edited to correct the fact I apparently can’t differentiate between “iPhone5” and “iOS6.”

Big Slackwater

Gorgeous view at Big SlackwaterIt’s a good day to be a C&O junkie… the Park Service has finally reopened the Big Slackwater portion of the trail, meaning we’re *this close* to having the entire trail reopened from Georgetown to Cumberland with nary a detour in sight. There’s the little matter of the much newer detour by Great Falls to dispense of, but that might be done soon.

In any event, riding this portion of the trail was of great consequence to me personally, because it was the only piece of the trail I had yet to ride… of course I’ve ridden the detour many times. It seems to have been worth the wait… it’s a 5 mile (ish) stretch that includes the formerly impassable portions that have now been converted into gorgeous concrete roadways mere feet from the Potomac. Figure the flooding issues will always be issues, but these structures don’t look like they’ll be too subject to the whims of the river.* Figure it chops off about 30-40 minutes of the ride compared to the former detour, which is nice because that’s 30-40 minutes closer to beer o’clock at the cabin on the second day of the ride from DC…

All in all, my favorite part of the trail. Good job NPS!

*Be sure to remind me with headline links to “Massive flooding closes C&O trail again” later this winter. Jinx.

Continental Divide

Top of the Allegheny's

Last week, I wrote about riding the GAP to the MD/PA state line. Sunday, I rode with MJ for the first time since our west coast adventures and made the trail all the way to the eastern continental divide. At a length of 50 miles round tripping from Cumberland, this was a fairly vigorous ride, but oddly easy considering the accurate, but misleading, elevation chart.

The ride confirms that the 135 miles from Cumberland to Pittsburgh is an “easy” 2 day trip, with a likely overnight in Ohiopyle State Park, or maybe a leave-no-trace wild camp if it’s appropriate (although probably not technically allowed). Unfortunately as the fall weather makes this trip beyond tempting, my fall schedule is tricky to coordinate enough consecutive days to make it happen. Since one of the tunnels closes November 1st, it might be that this section of the trail may be the only part I can do until next spring…

Riding the GAP

Sunday was a gloriously perfect day for a ride, so I drove about an hour west of my cabin to Cumberland, MD to check out the Great Allegheny Passage, a 130-ish mile trail linking up the end of the C&O with Pittsburgh. I’ve read some great things about the trail, mainly its surface. Sadly, I didn’t have the time to carve out a multi-day trek, but I got a good sense of things in my 41 mile round trip.

  • The surface is nice, but not as solid as I thought it would be. The crushed limestone wasn’t compacted in several spots, leaving a pretty soft slide when hit wrong. The portion I was riding had a slight incline to it, so on the descent things can get a bit dicey if you’re not paying attention.
  • Come fall, the vistas will be amazing… serious foliage potential. One ridgeline on the climb features a line of turbines… not a natural feature at all, but I’ve always thought they stand as a nice juxtaposition of technology amongst the wilderness.
  • The climb is not difficult at all, but it is about 25 miles long. By mile 20 I definitely felt it, but then again I never really took a real break to speak of. About MM 25, you hit the Eastern Continental Divide, so the rest of the ride turns into a gentle descent as you roll west. Since the climb goes pretty fast (and the descent even faster), I figure it’s reasonable to do the 130+ miles in 2 days (and therefore, the Pittsburgh to DC run in 5).
  • The train was cool, but the smog that comes out of that stack is no good for the lungs. The tunnels were nice and big for this claustrophobe, thank you very much.
  • Loved the Mason-Dixon line setup at the PA/MD border. I chose that as my turnaround point rather than tempt myself with what lay beyond the Continental Divide…
  • Oh, and the Bills won while I was riding. Like Cube said, it was a good day
