Re: Elevator to space?

Well, why not build it at one of the earth's poles, so that it isn't moving at 17,000 miles per hour. And how about using readily available material to create a tower, which would reach way up there? Oh yeah, the material would be seawater, frozen in massive layers, one on top of the other. It could...

Re: A "new" lithium battery, I've personally never heard of.

The only packs that use NMC are the 2012 packs. They don't have them listed for sale for another few weeks. Correct me if I'm wrong, but I'm assuming that you're referring to the Zero packs. Here's a link to the Spec page for the 2012 models. I'm also assuming that these new offerings will have the...

Re: A "new" lithium battery, I've personally never heard of.

NMC - buy a Zero motorcycle :wink: About the only way to get your hands on them. From what I've heard, it performs like Lipo with the safety and cycle life of iron phosphate. I'm always a bit skeptical about cycle life predictions until it's been real-world tested, but these look very promising. I'...

Whenever anyone says "I would never do XXX without wearing a helmet", they are subtracting against whatever small protection that helmet offers.
