By using alcohol fuel cells, is there a reasonable possibility of domestic electronic gadgets (clocks, radios, digital storage devices, flashlights, etc) powered by a little tank of methylated spirit that can be topped-up @-will?

I realise there might not be very many applications in which a regular rechargeable battery isn't the better option - although I would've thought that there are @least a few ; & I also realise that the materials (eg platinum, Nafion™) alcohol fuel-cells are constructed from are rather expensive ... but I would've thought that, on-balance , there would be @least a few such devices available on the market, for niche applications - eg when folk are out camping, or something ... but I haven't seen any, ever .
