It was Everready Extreme Edition or something like that.

All,
I came across this article this AM in the Dallas Morning News and
thought it was a great idea and a great light:

My apologies to Dave Locklear if he's already
From your explanation, it occured to me that since the batteries are not
sealed and you can go into the light and replace the 3 standard-sized AA
rechargeables, this LED light doubles as a recharger for all rechargeable AA
batteries. No need for a plug-in wall recharger.

That never occurred to me, Lyndon, but a great idea!
Another reason to buy 1 or 3!

Really my question is does it take more energy to release the hydrogen than is
produced by the ignition of said hydrogen?

It is the mark
Well, of course you can use water for fuel is you first break it up
into hydrogen and oxygen. Anyone who thinks he can get as much energy
out of burning the hydrogen as it took to separate it out in the first
place is invited to bid on my secret plans for a perpetual-motion

You can easily spend over $ 6,000 on a bicycle. You can buy one

David,
There are many cars out there that don't use a whole lot of steel in
their construction. For instance, the Mazda RX-8 I have has many panels
made of plastic**. Some high-end sports cars have even more made from
Carbon Fibre; however, that tells us that's it's quite expensive to
produce.
Of course the problem with making a significantly lighter car is that nobody is
making a significantly lighter semi. And when the two collide, well you know
which one's going to win...all over the highway. We need to get some sort of
equality w/semis.

I wonder why Ford or GM hasn't started making car bodies and more other
parts from aluminum. I would believe that we (U S residents and
visitors) throw away more aluminum cans than the rest of the world
combined.
For whatever reason, I have heard that some large aluminum corporation

There are millions of lighter cars on our roads, especially sub compacts
and smaller and most are of current manufacture thanks to gas prices.
Any serious collision between these cars and larger cars and trucks will

A big drawback of aluminum is its metal fatigue characteristics. You pretty
much have to expect that it's eventually going to fail, but you really don't
know when.
What I find really disturbing is that aluminum is used for airplanes. The

DC3's are not pressurized. Thus, they don't have the stress factor of being
inflated and deflated like a balloon every time they fly. That is one
reason so many are still around today.
