Need a lot of fuel cells

Biu · Jun 24, 2004

It is clean energy.
It can be re-filled fast....no charging time required.
Light weight.

Most likely major application in the future would be on hybird cars, notebook computers.

Today, phil put on the homepage about toshiba's fuel cell that only
outputs 100mw. You'll need 15 of these things to run a rebel. I
don't see what the advantage of these fuel cells are, I can see
with regular batteries you throw them away, and they pile up in a
landfill, but what's wrong with the current technology of the
advanced rechargable batteries such as the Lithium Ion (300d) and
Ni-Mh? They don't have any memory effect, and they can be made in
large capacities. Curious to hear your thoughts on this.

Or simply borrow a hit off of a co-workers QuickMeth or SuperNol bottle and be filled up in a few seconds. Or stop by the news stand at the airport to "top it off" as you pick up your banana muffin and $4 spring water quickly before boarding the plane. For all intents and purposes it may end up analogous to buying a "charge" anywhere within minutes, rather having to plug in for two hours to wake up that old li-ons. Sounds good to me.

We have fuel cells so-to-speak in our cars, and nobody bought those that had to be plugged in for a charge. Why will it be the opposite with laptops and cameras?

What happen to general adaptation of electric, natural or propane
cars? I guess the general public find them too inconvenient and
expensive. Imagine how much more inconvenient and expensive if cars
were power by fuel cells.

Try New Zealand for example. When I left there 5-10 years ago, a significant percentage of NZ vehicles (especially commercial vehicles) were running on compressed natural gas. Virtually every gas station in NZ has a CNG hookup to fill up.

Things may have changed since I left. Can any current Kiwis give a perspective on this.

Wow..if it can keep my DR running for month..Then it will be useful
for extended travel..such as travelling in wilderness,
mountain/jungle expedition..

One fill may not last you a month (depending on how you shoot), but the energy density of Methanol is much higher than the best battery currently, so you could just take a long a 1/2 litre of methanol refill with.

Non-pure Ethanol would actually be better because it would give you something to drink around the campfire without going blind! Talk about useful, fill up the battery with Russian Vodka, have a swig for youself and away you go! One for the camera, one for me... one for the caumura, oonne far meee.

The 300D as a drinking buddy!!!

Imagine running your house on a vodka powered fuel cell. If you're having a party, turn off the lights to save some vodka for the guests... Any bright engineers here want to go into business? I could do the marketing...

Quite true, but flammable liquids are prohibited by the FAA. (You
can have small amounts inside a cigarette lighter, for example, but
you can't have a bottle of fuel.)

So what? This is just like taking a stove on a plane with you.
You can't take the fuel. It's not a problem. You get fuel at the
destination. It's not like you can't get metho anywhere but
locally to you.

Even aside from that rather large flaw in your objection, given
that the FAA allows cigarette lighters (even though they are cheap,
readily replaceable, and smoking is banned) but doesn't allow
larger containers just shows that they don't really mind, and could
quite easily just start allowing it. If there was a genuine use
for such a thing. It's like nail clippers being allowed again. A
bottle of fuel isn't something that explodes as soon as you take
off, it's just potential, much like grandmas walking stick. (Which
is also allowed)

All they need to do is change it from Methanol to Impure Ethanol (I don't know if it would work of course - I'm not an engineer). Just buy some vodka at duty free - or even fill up on the plane!

I think we all know that airlines have very arbitrary rules, some of which are sensible and some aren't. I was actually allowed to take a flask of Brandy on a plane (which surprised me), but only after sipping it in front of the security person to prove it was drinkable.

But there's still plenty of LPG refiilers around, so presumably plenty of LPG powered vehicles to go with them.
