Aneirin -> Health and dwindling fuel, the solution ? (4/9/2009 7:35:38 AM)

With a recent re interest in cycling, I have come to the conclusion that if cycling were taken up en masse, a solution might be found that tackles the unfit/overweight issue and the rising cost of fossil fuels, at least for short distance travel for the majority. With more people taking to human powered vehicles, there will of course be a reduction in consumer created green house gases and other pollution, that should shut the politicians up, (we aren't to blame, look at your pals in industry and stop taxing us for nothing etc).

Cycles have moved on, even in the fifteen years of so I have been away from the sport, what is available now is staggering, no longer that rickety, noisy lump of rusty metal with a seat that felt like a razor blade after a short while. There are now and have been for a long time cycles called recumbrants, more comfortable and more efficient cycles where one more or less lies down or at least lounges to power the cycle. In fact I think one of these recumbrants holds the land speed record for a human powered vehicle, something like 70 miles per hour. There are also part time electric cycles, bikes where the pedalling motion not only powers the cycle but charges a battery so that an electric motor can be switched on to assist in pedalling, or allow motion without predalling.

The weather, always a problem, cycles are being produced with full weather casings, particularly the recumbrant class, casings which offer weather protection and streamlining and in some experimental machines, solar cell technology to assist with battery charging for the electric option.

Of course for the moving of heavier loads or travelling long distance, traditional travel means are necessary, but for the private user, some kind of HPV could offer health benefits and a cheap reliable means of personal transport.

Interesting view for those in the US, but it applies to all

check out the video and as it says, share it with your statesman, a use for suffering auto manufacture industry, save the planet and health for all.......maybe.

Cycling is very much on the rise. That's the plan because cars of ANY kind will be a real luxury in just a very few short years. Those who care to observe middle-class impoverishment will see that is part of the basis of letting the big 3 go bankrupt, if necessary. It will be a little like letting the gem industry go bankrupt.

You see, soon they will not be selling cars because they are not what customers want...they will be trying to sell something most people won't be able to afford.

This will not be a reinvention of the horse and buggy although that is another alternative to cars but a devolving of our middle-class standard of living.

Devolving of the middle class standard of living, does that bother you ?

Me, I would sooner have, in the case of transport, the freedom to be able to use that vehicle when it is necessary to use it, without the exhorbitant costs involved, there freeing funds for the more important things in life, or making it unnecessary to slave most of one's life just to get the funds to meet these rapidly ascending charges.

Having watched the video and reading through the website, I see this project as being another application of using inertia generated by a spinning massive flywheel to propel a vehicle, in its basic design. This time, however, the project leaders are using human power as the force that gets the flywheel off to its spinning start before enough inertia is built up to apply it to the drive wheels. About thirty or forty years ago, it was small electric or gasoline powered engines that drove the flywheels.

The idea seemed to hold promise at the time. However, IIRC, one of the major drawbacks was that flywheels of that age were being literally torn apart, with sometimes fatal results as the high-speed fragments were flung about like shrapnel. Perhaps with materials of today a flywheel system can be constructed that won't have a tendency to tear itself apart. If it can be done, I think it's a good idea to pursue this concept.

Pertaining to the presenter's and the web site's reference to this vehicle being powered by computer hard drives, I'm having difficulty in understanding their terminology. What looks like old style flywheels to me are being calling "hard drives" by them. I don't know about that; maybe I'm over-thinking this part of their project. Despite this, I can see the promise this type of propulsion may have.

I can also understand the concept of having one vehicle that uses two modes: running around locally using some sort of self-propelled drive (like human or small electric/gasoline engine power) but when needing to cover long distances, linking up onto a guide-way system and being propelled via magnetic levitation. Again, this was a concept explored back in the '60s and '70s (in my lifetime) in the pages of Popular Science and Popular Mechanics magazines.

If such a transportation system could be viable, I'd certainly give up the gasoline and/or battery powered choices of today. Until then, I have no other option other than to run my PT Cruiser as sparingly as possible and saving my coin up for a nice Catrike or equivalent.

Once all the road tire and wind resistance problems are solved, I guess it could work. However like anything else there are drawbacks. Now if you want totally green, go totally green thus taking the case of the purely HPV.

It is going to take human power some time to store up the inertia in the flywheel, and it may be necessary to sit there and pedal or whatever before leaving. This would be the case when the highway ramp is close to one's parking spot. However the flywheel has to also be charged on the fly, because there may be that next burst of acceleration needed.

If one is in stop and go traffic this can be accomplished of course by using the flywheel to brake the vehicle, but on the long road things are bound to be a bit different, in practice.

That website obviously depicts their thingamabob (I love those technical terms) in the very best light possible. Somewhat like the one's who sold my buddy the "run your car off water" kit. I think once he actually uses the thing he is going to find out that it is more trouble than it is worth.

However that is in no way to say this thing has no use, it certainly does. And of course it will not get the trucks off the road. Everything you own comes on a truck, even your truck.

Also, here in Cleveland sometimes the wind blows full size trucks around on the road. What of these things ?
