Much of what we have have isn't the best possible, merely the most profitable...

An employee of Toshiba Corporation charges a methanol liquid into the company developed prototype direct methanol fuel cell (DMFC) powered HDD-based digital audio player at the Toshiba headquarters in Tokyo September 16, 2005. The HDD player can running for approximately 60 hours on a single 10ml charge of pure methanol. The DMFC units can be integrated into devices for a digital audio palyers or wireless headsets for mobile phones expected to appear in commercial products in and after 2007, Toshiba said. View AttachmentView AttachmentView Attachmentmaybe they realized and asked them selves, how are the common folks going to source pure ethanol? I've asked the same, why they dont do a DAP that features removable batteries like NiMH, alkaline (9v, C, AA, AAA) or camera Li-ion battery packs |

I was reading on different rechargeable battery techs like NiMH and NiZn.
The NiZn have a nominal voltage of 1.6v and low mAh ratings, whereas NiMH have 1.2v and good mAh, have seen AA batteries with 2400 mAh and C or D with up to 4000 mAh. NiMH also has 9v atyle with i think i read 2000 mAh.
This is one problem as to why DAPs feature no replaceable batteries. Li-ion are 3.7v with mow whopping 10.000 mAh
