"weight" of methanol 

Roughly 0.8grams per cc

Powerless 

"Laptop-friendly" and "10 to 20W power".

You're kidding, right? That's surely no-where near enough power to supply most traditionally sized laptops.

Methanol: Density 0.7918 g/cm³, liquid*

So about 160g reducing to 0g over time.....

200 ml of methanol. 

That means that with methanol having an upper band price of about $4.25 per US gallon, this will cost 22 cents to run, however, if it really gives only 10 to 20 W what's the viability?

Still using methanol in this way is probably better than drinkinbg the stuff!
