I have just read the Geekzone article referenced above. If the Toshiba battery can output 300mW for 60 hours on 10ml charge (that's 300mW x 60 = 18W total output per 10ml of methanol), then one gallon should be able to produce 6,618.72W.

The X50v consumes 5.3W max. One gallon of Methanol should be able to power it for 1,286 hours minimum. You Axim will last 6 months on a 7 hours/day use.

Yeah where would the water go? water + electronics = bad.

The longivaty of using methanol is great but do you remember the portable cd players? and how they would run out of batteries?

First you have to find methanol, then you would have to pay out of pocket. I'm satasfied with the current method(just not the longivaty) run out? plug it in.

I'm waiting for the so called "Nuclear powered mobile device" now that'll be something. 30-40 years on a charge.

A similar way of producing power is the PEFC (polymer electrolye fuel cell). Pretty much the same thing except it uses Hydrogen (gas) insted of methanol. They are being tested in cell phones:

I had to do a huge research review on PEFCs for a senior project (i was a chemistry major) last year. I have to say, these look pretty cool.

Not to even mention.. you won't EVER be allowed to use this on an airplane.

how about a cradle with a methanol pump?
when you put it on the cradle, it fills the missing methanol... no spills!

blah. imagine overclocking your x50v, getting it too hot, and making the methanol go boom.. impossible but heyhey =).

I still think it's better. God, I would appreciate that on my laptop.

Interesting none the less. I would still be skeptical of using fuel in my electronics. I know the portable life would be impeccable but something bothers me about having a fuel cell in my pocket with my electronic device. Oh well, I can't wait to see how this takes off.

By the time the fuel cells are widely available for the mass, it must be exhausted with approvals from various safety organizations, and applicable government agencies. By then, all of your concerns about water byproduct, leak, spill, availability, etc. would have been soundly addressed.

C'mon guys. No doubt when someone first thought of this technology, they would have the same concerns as you now have. They have had many many years of research to address the various issues to make this technology a viable product, and you only spent 15 minutes on this idea before complaining about the obvious.

If you say water + electronics = bad, then how about gasoline combustion + human flesh? Does it prevent you from driving your car? When gasoline-powered cars first became available, I bet you would say it's a bad idea because "where would you get the gas?"

Li ion will continue to exist for a while. Methanol fuel cell will complement it. At least, that's what I read from some market analysis for this technology.

Gasoline combustion isn't happening on the surface of your body, it's happening in a control environmnet.

I'm not saying i'm against this or anything, I would love to have a better poewr source, just bringing up some concerns, like where would the byproduct go? the byproduct is water and water being a byproduct of an electronics device? that doesn't sound good. they'll probaly find a way around this, I'm just asking

and what makes you think the chemical reaction in a fuel cell isn't in a controlled environment?

This technology is still a few years away from general availability. There are valid concerns about methanol being a flammable substance, which could cause security problem on airplanes and such.

Obviously, everyone wants better power sources. I for one would love just to be able to fill my car with tap water then go, but it's still science fiction. We are here to discuss reality.

I didn't say that the chem reaction wasn't in a controlled environment. I said that water(the by-product) isn't the best for an electronic device.

You can relate that to emissions effecting a persons lungs or something similar, that's a better analogy.


I never said that this wouldn't be safe(blowing up and whatnot) or anything, i'm just trying to ask: "what about the h20"?

why are all of you so adverse to carrying around methonol in your pocket?? at a 30% solution even. i have carried around a butane lighter with me for 15 years and have never had one explode on me or harm me in any way, and i think pure butane is just a little more flamable than a 30% solution of methonol. open your minds alittle bit people. all of you that are not up to embracing this new technology sound scared of it and unwilling to leap into the future.

I'm worried about the by-product "H2O" WATER, LIQUID ON PDA NO GOOD

I'm not worried about carring around methonol, im worried but WATER.

Isn't the water generated VERY miniscule, considering the amount of chemical present?

Does the water output, or is it left in the solution which is already 30/70 (methanol/h20) until the solution is 0/100?

And if it DOES have to output, would it be any more water than what the device already comes into contact with via sweat/humidity?

If 30mL gets 60 hours of performance, that means 30 mL of water over a 60 hour period of active use is outputted. An amount that small will never amount to anything harmful.
