Samsung Working On Fuel-Cell Powered Cell Phones
An anonymous reader writes "BusinessWeek reports that Samsung plans to build prototype phones that will be powered by Direct Methanol Fuel Cells." From the article: "The deal also marks a huge vote of confidence in a little-known company. MTI Micro, which had sales of $8 million in 2005, is one of a handful of outfits seeking to bring hydrogen-based fuel-cell technology into more common use. Its Mobion fuel cells have already appeared in industrial handhelds from companies like Intermec, a unit of Unova, and have drawn the attention of military contractors developing devices that soldiers will use in the field. Under the deal, which lasts through the end of the second quarter of 2007, the two companies will jointly research the use of methanol-based fuel-cell technologies for use in cell phones. Any patents that come as the result of the research will be assigned to MTI."
So people are going to give up being able to recharge their cell phone batteries for free for the ultra-convienence of having to go to the store to buy new fuel cells for their phones
Yeah, I too kinda wonder about the logic behind such a product.
I also have to wonder just how much more eco-friendly this would prove over the life of a phone - For a ballpark calculation, people replace their phones every two years and current phones need charging every two to three days. If this cell lasts twice as long that means it will eat between 120 and 180 cells over the life of the phone. Does one Li-ion battery really cause that much damage to the environment that 180 PEMs+tank represents an improvement???
For bigger things, like laptops, I can see the use of fuel cells as an auxilliary power source (though not replacing batteries outright). But for a cell phone, they last three days, not three hours, per charge. Even then, though, I have to wonder just how popular they would prove themselves.
Mostly, I see fuel cells as useful in places where we already use fluids (ie, gasoline) as a source of power, such as cars and generators. I also see a possible secondary market in places we currently use mostly non-rechargeable batteries, such as flashlights and radios. But targetting cell-phones, laptops, or any other device that already uses rechargeables seems like a sure way to make sure fuel cells never become popular.
Batteries have always been nasty, from the very first lead-acid batteries on to today.
Lithium-ion batteries, for instance, have the habit of exploding when charged. It took a lot of engineering and electronics wrapped around the charging of lithium-ion batteries to make them safe for consumer use.
But when's the last time you heard about a lithium-ion battery exploding on someone? I haven't heard about it in a while. And it's been even longer since I've heard about it when it wasn't the person's fault.
There are "questions to be answered", sure, but you sort of act like this is news. I could equally write a "questions to be answered" post about automobiles, starting with the impossibility of storing gasoline correctly. There are people who can answer those questions called "engineers", and while I wouldn't jump on the first iteration of the technology, the battery field has a pretty good track record overall. If it comes out for consumer use, it'll almost certainly be very safe after six months on the market.
I'm sure your phone will never use as much energy as was used to create that solar collector :-)
