the question is, how much does the engine produce, how much is needed to propel the vehicle. ICE do it relatively well (alternator and much of the pumps -mechanical and electrical) but at the expense of MPG. may be by adding something to the breaks it would be better
all in all it looks like a differential eq which has a solution ... now is it practical or not I can't say (I'm no expert in chemistry).

well, diverting some of the energy to power the alternator, it doesn't have to be a perpetual motion (which is supposedly impossible). just a way of extending, if a tank will run out in X hours or X miles if left alone without additional production, it'll run out in Y hours/ Y miles (where Y >> X), at that point you'll have to fill it in some way or an other (just like with ICE cars, gas stop). or what you said :)

I meant electrolysis not hydro... , and it was a simple honest question, no point.

how about creating it in the care using some kind of alternator to generate the electric current needed to for the hydrolysis?

it can be obtained from water (Hydrolysis) no?

not even you can decrypt the message once encrypted with the other person's public key. The only key capable of that is the private key of the recepiant.

modems (DSL, not DOCSIS: see below)? if not free rental it's a rippoff (new 50-70$ used 5-20$, they last years).
TV boxes? well, may be. But the thing is if you want this or that tv/cable internet provider, you need their box,
you can buy your own (except if you bought it used from an ex customer of the same company) sot they charge what ever the hell they can get away with,
especially when they control usually a very large proportion of the market.
(where I live we have mainly 2 big companies : cable (videotron) VS sat (BELL), rpices a re almost the same, the deals too).

a large(sessor) camera is not a requirement for that. doable with a compact point and shoot (not as noticiable nor beatiful but still).

most point and shoot are less expensive (less than 200$) , smaller and waaaaaaaaaaay better than any camera phone out there!
sensor size alone is not comparable.

I was expecting it :)

no why?
But from a link from a link in TFA : make trolls pay http://www.nytimes.com/2013/06/05/opinion/make-patent-trolls-pay-in-court.html?smid=pl-share&_r=1& . "This particular judge is trying to do it" would be a fair assumption
Unfortunately I can not be in a jury like this one : I'm not a US citizen. I'm Canadian and if there is ever something like this her I'd ask the same question and I'd be happy to.

yes, where de I signe ?

and i've seen them more often than not turning those lights on for the sole purpose of not stoping at a red light!

Of course, he did. I'm the cop who arrested him, btw. He'll be spending a long time in jail

and break too (for hills)
