Micro Fuel Cells surge with power to spare

OogamrM writes "CNN (http://www.cnn.com) has a story (http://www.cnn.com/2002/TECH/ptech/09/22/micro.fu el.cells.ap/index.html) about a new generation of fuel cells. They are so small that they are expected to be able to replace batteries in mobile phone and notebook PCs, and last 10 times as long as the best batteries available today. "In the long run, just about anywhere where high-end batteries are the right answer, these devices should be a better answer," say one fuel cell developer. Expect to be able to buy one sometime in 2004."

This is one step in the right direction

Technology like this is one step in the right direction.

Another step would be for consumers who buy laptops to consider battery life more important than raw megahertz. Right now, Intel (or AMD, or someone else) could create a Pentium or Pentium II clone using modern .013 micron technology which would consume very little power and generate very little heat.

For anything besides video game playing, the equivalent of a PIII 500 is more than adequate.

Another area where battery usage in a portable can be decreased is by using solid-state memory instead of a hard disk. It should be feasable to have a gigabyte of solid state memory in the near future; this should be more than enough for OS + Web browser + basic office suite (I remember complaining ten years ago that Microsoft Word was all of 15 megabytes big).

The display looks to be the biggest power-hog which current technology has no really good solution for. It may be possible the electronic paper displays will use less power than a current TFT display (which needs a strong backlight to go through 3 layers of LCD display).

With all of these technologies combined, one may be able to make a laptop which lasts over two or three days of continous usage; for example, over a trans-pacific flight or on a long bus trip. Another example: This would allow one to use their laptop for basic email checking over a two-week vacation without needing to charge the beast.

In this scenario, a fuel cell powered laptop would need a reactant cartridge that the user must throw away and replace periodically.

When refill kits for overpriced ink-jet cartridges have been the rage for years, how long do you think it would be before someone had a methanol refill kit for your fuel-cell cartridge?
