Comment: Light but reactive element = high energy density (Score 1) 142

"lithium is in the upper left-hand corner of the periodic table. Only hydrogen and helium are lighter on an atomic basis."

  I'm wondering if this is a non sequitur for electric batteries.

Not a non sequitur at all.

An important factor for batteries is energy density: How much energy is stored per unit mass. This is particularly important for electric cars: The higher the energy density, the less mass you havce to haul around for a given amount of "fuel", which means the less "fuel" is spent hauling your "fuel" around, so it's a more-than-linear improvement.

Lithium is both extremely light and a very reactive nonmetal. So you're talking about a lot of energy per unit mass for the lithium-based electrode's contribution to the reaction.

Or... and this may sound zany but hear me out. Maybe 51% of people did a risk/benefit analysis and decided that giving someone there password was actually beneficial for them.

Not possible. Only people who use devices in exactly the same manner as that proscribed by a /. nerd can be beneficial. (No wireless, less space than a Nomad...)

Other than the rebroadcasted major market channels KIIS and Z100 on channels 11 and 12, what music channels are playing commercials?

Channel 76 and below (except 11/12) are all still commercial free. I can't speak for 77-79 (kids), and some of the 140+ Latino channels, but...

What music channels, exactly, are playing commercials on XM?

Stop screwing up the nerdrage with pointless facts.
