If you can do this, good for you (and the rest of humanity). Let us know when you succeed.

Another tidbit of fodder for the active minds. Wow John, you sound like a very serious dude. ALL of your dreams are based (solidly, no less) on practical realities? Jeez, you're some sort of biological anomaly. Would you consider volunteering for a clinical study we're conducting here at the University? Haha- just giving you a ration! Yes, you stay back there in your realm of safety and "sanity", and leave the grandiose dreams to others more willing and qualified. As far as raining on my parade goes, well, I don't quite believe you when you say you didn't mean to, because you did mean to, and in your most recent reply you still give subtle attempts at just that with your "waste my time... on what is unobtainable" , and even "firmly planted on Terra Firma" I hope you manage to sneak in a totally wild and carefree dream in between your "back to the salt mine" dreams, otherwise your heart will likely grow hard and bitter, and you'll spend your time knocking those who dare to dream...Space Cadet Ted, signing off

Re: Hybrid Theory: Need electrician help

So I haven't weighed in as promised...I truthfully kind of forgot about this thread...but I will point out that commercially available hybrid buses are parallel electrics, as are all other commercially available hybrids. There is a BIG difference between that an a series hybrid.

*edit* I stand corrected. Those buses to look like they are series hybrids. Series hybrids are, however, illogical for widespread use and really can only be more efficient in a small niche market. i don't think buses are one of them. A parallel hybrid could be. There is nothing fundamentally fuel saving about a bus that uses a diesel engine to charge batteries that then release their current to drive traction motors. The ONLY way that design is energy saving is if the prime mover is meticulously designed to run at a very high peak efficiency all the time. The problem is that electrical loads on the system vary greatly and will likely fall outside the capabilities of such a prime mover.

Re: Hybrid Theory: Need electrician help

Well, I apologize for having a hand in turning any of this into personal debate of a hijacking nature. My intentions were never really to discuss PM, anyhow. I just gave a brief nod to the idea, and it was more about the air bearings on the bus RiktorD was eyeballing. I don't feel like I hijacked the post by the mention of them, nor the magnetic bearings. Both are being used, and hopefully someday will be incorporated into many of our oil guzzling machines to reduce that dependency. This stuff is happening, and it's fun to talk about and dream about, and mold them into reality. I don't see the need for exclusion of ideas solely on the basis of whether or not they're deemed practical by any one. Anyhow, I've got all the nuts and bolts issues of my own simple life in good order- thus the free time to discuss things both practical AND fanciful. I believe the two points meet often, but then again, it's all in the way we look at it. Converted buses seem to me a good mix of the two. They don't require names, but it's fun to give them to them anyway.
I enjoy seeing people reach for their dreams, and while they might not be dreams I'd call my own, it still feels good to see people dream, dammit. Even if you think someone's dream unattainable- what? you go and dowse their dream with laws and facts explaining how it won't/can't work... that seems downright rude and obnoxious to me, unless they asked for your take. What's the rhyme or reason to that? (dig deep) What's someone's dream hurting you. No one here is forcing their dreams down anyone's throat as far as I can tell. Dreams are powerful, as well as fun. I want to see RiktorD's thoughts materialize. If they don't, so it goes. If they do, then hell yeah. I'll feel like I was a small part of something cool and worthwhile, even if it was really just B.S.ing over the comp.

Re: Hybrid Theory: Need electrician help

Glad I found this thread, even though it looks like discussion got testy quickly, then just fizzled out.

I'm only interested in the concept of a hybrid-electric bus/RV as a matter of theory. The main reason for that is that I do not own, and am not sure I ever will own, a bus/RV. Why, then, you may ask, my interest in the topic of hybrid-electric buses/RV's? Well, I'm interested because having a bus/RV offers the possibility of living a really frugal lifestyle--provided one lives on their bus/RV, as opposed to just taking vacations in it--and frugal lifestyles interest me. Which brings me to why I do not currently own, and may never own, a bus/RV: I don't own one because I doubt I could live more frugally on such a vehicle than I do in my current living arrangement (I do some work for the apt. building I live in for a rent reduction).

Ok, those caveats out of the way, here's why I've come to this forum with an interest in hybrid-electric buses/RV's: because I want to have a frugal-living back-up plan in case my current rent-reduction scenario ever, due to circumstances beyond my control, ends. Should that ever happen, converting a bus/RV for living purposes would begin to become a really attractive option.

With that said, I can add a further reason why a hybrid-electric system would be a desirable one for my purposes. Should bus/RV life ever be in my future, I would not be looking to be traveling on said vehicle year-round. Rather, I would want it to be parked in one or another spot for as long as possible/feasible, moving the vehicle only when necessary (neighbors too noisy, found a better parking rate elsewhere, etc). That qualification having been made, the hybrid-electric model looks attractive because a very good electricity generating system would not need to be added to the bus/RV, since it would already be built in--it being also the primary means for the vehicle's propulsion.

In any case, as I go on "dreaming" about this possibility, can anyone point me to any further discussions on this forum about hybrid-electric schemes for buses/RV's, or related resources on the web?

Thanks,
James

Costs me a tad over a C note a month to live in my own bus, on my own property, including tags and insurance for the bus, property tax, generator fuel and propane. Live pretty much the same as I did in an apartment in LA, except my bus is larger than my apartment was and costs about 1/12 as much. Doesn't count groceries, of course, that's the same no matter for either case.

I's think that the cost of adding a domestic electrical system to a skoolie is a pittance compared to the cost of buying a hybrid-electric bus - if you can find one - and adapting it's electrical system to domestic use.

Thanks for your input, wtd. That's some pretty frugal living you're doing there--gives me a good target to aim for. Your property is undoubtedly out in the boonies somewhere?

Yeah, I could never justify the cost of a new--or likely even used--hybrid-electric bus. Nor would I want a production RV with any kind of standard interior. I'd want something I designed myself. So what I had something in mind for the powertrain is more like a home-brew project--kinda like the Opel they set up as a hybrid-electric back in the 70's and wrote about in one of the Mother Earth News issues, only on a larger scale. I recall they used a military surplus jet starter motor in that vehicle--a motor that would, of course, be so appropriate in a much larger vehicle like a bus-RV.
