    A Green Machine that's not a Kawasaki

    A friend from Australia sent me this link. I always like a story that's current.
    The original story is here.



    Electric Motorcycles: Cool and Green
    There's nothing wrong with "cool", and we have to admit that few vehicles are cooler than motorcycles (at least in theory - not all of us would ride one). You're basically sitting on an engine with wheels. Can't get much simpler than that. They're not always practical, but the people who love their bikes really love them.

    But cool is not enough. The vast majority of motorcycles are still running on fossil fuels, and that's a problem. As battery technology improves, we're starting to see more electric motorcycles: Some are commercially available, many are DIY custom jobs. Today we look at some of the coolest ones.

    Electric Motorcycle No Need for Gasoline

    The bike in the first photo at the top is Electrocat, and the rider is Eva H?Ñkansson. We're starting with her because she is a true pioneer in the world of electric motorcycles (she describes herself as a "hardcore 'EV geek' with a green heart and passion for power and speed.").

    She has built Electrocat with her father, Sven H?Ñkansson, and it is probably the first street-legal electric motorcycle in Sweden. It is based on a Cagiva Freccia C12R model year 1990, but the insides are pure electric goodness.

    In the picture above you can see the Electrocat's "Thunder Sky litihum-iron-phosphate cells and the original Briggs & Stratton Etek motor". The blue box is the Alltrax AXE7245 controller. Charging takes half an hour on a powerful garage charger (longer with the smaller onboard charger - about 7 hours) and range is 80 km (50 miles) per charge at 70 km/h (44 mph).

    You can learn more about the Electrocat on Eva's great website.

    50 miles and then a 7 hour charge? So how long would an Iron Butt take? .......let's see, carry the 7.........divided by..........5.3 days. Yeah, keep working on it. Don't get me wrong, I'm all for "Green" products, whether you buy into the man made global warming or not, polution is a bad thing, no way around it. But until somebody comes up with better battery technology, I can't see it being a big seller.

    I remember when the first hand help calculators cost over $100. Picked up one in the dollar store the other day for ... $1.00.

    You are right. The range for the green machine is not impressive. I can do better on a bicycle and a good ham sandwich.

    Hope springs eternal.

    All this and 44mph too?

    Hmmmm?

    Good, BUT? How much gas, oil, nuclear or coal energy does it take to "charge" that thing everytime?. I wonder how green it really is, when you figure we need to refuel the batteries. Of course I did not mention Solar, wind and water sources, which I should not leave out. Today, we still require all the above for all of our electricty, so keep working at it. I want a 500+ mile range, at the very least and maybe a mini nuclear powered bike will come about someday, with unlimited miles, speed. Cold fusion would be nice to invent! I'm working on it. Randy

    Thanks for posting the article Paul. I am glad to see someone is ÔÇÿpurposefully wonderingÔÇÖ about the internet for bike stories.


    The cottage development of alternative motorcycles has centered on electrics for a variety of reasons. The problems have been detailed fairly well here. Hydrogen may find its way into bikes first because of them.

    I stumbled across a research article on the development of storage tanks for hydrogen cars. The studies goal was to find lighter metals with the structural integrity to do the job. I am not an engineer or metallurgist so the details were lost on me; however, the research sounded promising. The article suggested the result in application was a storage tank that was substantially lighter than current tanks or a battery pack required to propel a vehicle and offered substantially more range between fills (~80-90% of the range of a similar gas tank of the same size). Sorry, I did not save the link - ?Reuters, MIT Journal or something else?

    Hydrogen seems to be beyond the development capabilities of the current cottage motorcycle developers and lacks the ubiquitous infrastructure that gasoline and electric alternatives currently enjoy.

    One big problem with hydrogen: at present, there is only one way to get it that does not require a greater input of energy than the hydrogen will yield. That method is to extract it from petroleum. No surprise that the Shrub was so big on hydrogen.

    Some friends and I were speculating on what things would look like today if the development of electric power supplies had been further developed when cars started hitting the trail. It is ubiquitous now but limited then and so the early electric cars lost out because gasoline powered cars were easier to feed. Seems we are in the same sort of option/supply paradigm situation now.

    Then we ran out of beer and called it a night.
