It would be really nice. Better battery technology would enable a lot
of things. I'd love to have a laptop, GPS, PDA, or cell phone I
didn't have to charge every other day.

There's a whole line of electric mini RC helicopters using lightweight
super small Li-po (lithium polymer) batteries. The big problem with
them is they're REAL picky about how they're charged, and they REALLY
like to explode. They need special chargers and you MUST use that
charger.

These things in my helicopters are literally the size of a vending
machine pack of gum.

Essentially gasoline and batteries are "portable energy", one chemical
and one electrical in form.

I can't really see a compact battery that's going to be very safe. If
you stuff that much energy in a really small space, it's probably not
going to be very stable. Think about all the laptop battery fire
stories you've heard recently.

I'm hoping supercapacitors or fuel cells do start to pan out.

I think that within 5 years we will have working versions of these tiny turbines:

You could have huge, huge energy densities with these turbines... Annual cell phone "refills" won't be too far away.


I'm nto so sure that this souinds like something I want to
have in my front right pocket, if you get my drift

" Inside a tiny combustion chamber, fuel and air quickly mix and burn
at the melting point of steel. Turbine blades, made of low-defect,
high-strength microfabricated materials, spin at 20,000 revolutions
per second -- 100 times faster than those in jet engines"



I'm half joking. haven't had my morning coffee yet so don't take this as too serious.

Most of this stuff is BS of the highest order. Somebody wants to get a government grant or make a killing with an IPO so they hype whatever it is they have come up with. You see things like newspapers are now maximized for profit which means they can't investigate stories any longer. The days of things like The Washington Post's Watergate investigations are over. What they publish now are the literal equivalent of Hollywood press agent releases. That and people doing self promotion to get their 15 minutes of fame.

That being said, we could get used to it if it was real. I mean we ride around on bikes or in cars with gallons of highly flamable gas. We fly in airplanes at ~40,000 feet.

I think we could be using fuel cells in the future. I think Germany has already installed plants that run on Methanol vs. Hyrogen. The ideal fuel cell would run on sucrose/sugar and the only by products would be water, alcohol, and CO2.

I really mean, "What a perfect world that would be!"

You ride your motorcycle to the nearest fast food place, drink your battery and replace the go juice with a glass of water and a couple of sugar packets.
