Hold on a minute I thought U said and I quote'
'In addition to running a number of startup businesses, I deal on a daily basis with funding new business ideas across a wide range of technologies.'
And now you are pleading poverty, cum on man don't be a SKINFLINT, d8veh don't come cheap.

nope *that* was ME (unless he said it too) and by the way, i still plead personal property, i just have access to spend other peoples money ...

WELL d8veh,
i must say that that is still all Chinese to me.
BUT~ Thanks for still coming back on it. { had thought THE MOVE was a demotion in some way }

I WONDER~ would you be a Skype user, and if so would you consider a vid talk that way ? Recorded that is.

I believe I've observed something that has possibly been missed, BUT~ I'm finding that everyone wants to second guess it rather than just answer questions.

If you are as said THE MAN with all those skills, I am prepared to pay for your advice on the hour, but I'm unemployed so can't pay much AND ~ would like to, *if right*- go ahead with getting *it* made.

OH my Skype name is OneVixler, if interested.

All my services are free, but you have to keep it in the public domain. You mentioned open source, so let's keep it like that.

The difference between a german and british engineer was traditionaly the german washed his hands after going to the toilet?

just a point of interest.

 

[YsFLY]

GOOD !
Open source it is ! That's why I suggested recording the talk, everyone else can then either see it or get a laugh, in the process.

Oh I get my stripend tomorrow so please lets leave that day out and come back to it on Thursday. Lots of running around to do in other words.

Hey! that's my Money! give it back man!

Hey! that's my Money! give it back man!

still 3 short of that final 6 i see, countryman.
May I ask if you line up on the lost side of 1066 or think you're line up on the *down* side of it ?

Either way~ is it really Our money, especially considering no one has bothered to ask Us~ for any sort of me/us value with which to decide *IT"s* value in the 1st place.

If you're interested in getting some sort of explanation to that ~ Try U/tube 'tensixtysix1' vid - 1066.. onwards ? A nightmare.

 

[mike killay]

Hello to all of you,
* MAN I WISH IT WAS THAT SIMPLE *
1st my name is Lloyd, but I would rather you used YsFLY from here on in.
Why?

OK~ So What am I about, well~ I contend that it is possible to power a bike *without a battery* .
Not altogether sure how just yet but have what most of you will have heard before - belief i.e. " I just know it's possible " .
Sort of Shamanism?

My problem is that my ignorance is also legendary, and in order to achieve that impossibility I am going to need the sort of physics brain that will allow for an Idiots approach to doing so ~ an awful lot of Ys & Ys not flying about~ in other words.

Now I know most of the bike posts here rely on batteries for motive power and mine does too, BUT I've found that a replacement battery will cost about £300
AND THINK~ not that that's out of order but that It's possible to produce an alternative for that sort of money, and one to boot that will not need replacing EVER !

I would like to look at those alternatives ~ as said, and am wondering if anyone a) has the necessary skills and b) if any else is interested in this sort of conundrum .... SOLVED.

IF SO~ Please respond here with .... ? & oh yes I have given it quite a bit of thought just no idea about the physics (numbers) involved.

Frankly, this is a load of nonsense.
You have absolutely no idea how your battriless bike is going to be powered, but just like Tony Blair, you believe.

 

[amigafan2003]

YES ~ @ last precisely.
BUT the real key here as far as I'm concerned is " what force is required AND for how long is 1 down push of peddle " AND ~ how does that equate to the demand upon battery.

AND~ YES I know that seems to be contradictory BUT ~ to me they are related.

The power requirement to propel an average cycle with a rider weight of 70kg and an average drag coeficient @ 9mph is approx 30watts. Each pedal down stroke would thus be 30 watts as well - but technically you're measuring a turning force there so you'd be looking to measure torque, not watts. Also, the power required increases logarithmically with speed. The logrithmic rate increase can be reduced by attempting to alleviate the impact of the cause of this increase - primarily wind resistance followed by tyre friction and lastly bearing friction.

For a motor to achieve the same speed, you'd have approx 40watts from the battery, allowing for 75% motor efficiency.

But I don't know why I even bothered replying to this thread - it's utter nonsense as far as I can see.

Can I safely assume your first language is not English?

I take it your use of the word Believe~ you know what it means.

Would you rather I didn't have it in both my lexicon as well as my head, If yes~ consider this ~ " I believe You can't be the fool you currently present yourself as."

Are you familiar with the 419 code that applies to badly written and poorly structured banking scams. not quite sure where you are going with your inquiries but to misquote
If it smells of a 419 it most likely is a 419.

*************************************************************
Thanks~ that helps, would i be right then in saying that 30-40 watts per second is what the motor draws.

AS FOR NONSENSE~ maybe, I didn't say it wasn't, just that I *believe* I've observed something that may have been missed, in fact even went so far as to say i may be just an Idiot.

BUT~ would you know if you where one without at least trying to find out if indeed that be the case in the 1st place ?

Watts is an instantaneous and continous measurement - you can't time define it - if you want to say something like "per second" then you should use something like watt hours.

My earlier reply said you need to apply a constant 30 watts to move a bicycle @ 9mph. I did not say "30 watts per second" or anything of the sort.

You said you've got an a-level in physics yet you display a fundamental misunderstanding of units of measurements with regards to "power". I'm wondering if it's worth continuing this discussion.

That is perhaps the most coherent sentence submitted to date by you Mr Fly..... a 419 is a scam that usually begins with a letter or email or post sent to a selected recipient or group making an offer that would result in a large payoff for the victim. The subject line often says something like "From the desk of barrister [Name]", "Your assistance is needed", "superb business opportunity" or offers the chance to be in on a unique and ground breaking discovery/product whilst actually withholding any pertinent detail. They often are from Nigeria hence the nomenclature, this being abstracted from what has become known internationally as "4-1-9" fraud after the section of the Nigerian penal code which addresses fraud schemes,some of which are often very creative and innovative and often constructed in poorly expressed english. Hope that clears things up for you.

OK ~ so what would be required per second to move a 100kilo mass(as in bike and rider) @15mph~ AT the peddle

OH~ and please remember ~ right from the start... I've said a lot of *idiot* questions is what anyone responding to this and me... is going to get.

SORRY~ like most i would really like to think I'm a genius, BUT~ time and evidence unfortunately have proven that ~ a true genius a) never thinks he/she/it is and b) will always check,,,, just in case.

******************

Clear ! thanks

BUT~ are you then suggesting that I'm endeavouring to follow their example ?

If so please go back~ and look at the post that says~ talk via Skype ~ AND I WILL SHOW YOU ~ FOR FREE.

 

[amigafan2003]

*******

OK ~ so what would be required per second to move a 100kilo mass(as in bike and rider) @15mph~ AT the peddle

To go travel at 15mph as opposed to 9mph you would require an approximate 3 fold increase in power output - approx 90watts (we're assuming a road type bike - it could be as high as 150 for a typical mountain bike).

You will be looking at an energy expenditure of approx 90 joules per second.

Someone has already done alot of the hardwork for you YsFLy ;-)
