I'm curious as to why you would introduce a low-efficiency inverter into the mix when trying to charge a low-voltage battery such as the one on your laptop battery. You'd be much greener (both macro and micro) if you used a purely DC path from your main battery to the laptop's.

Tobasco is nasty. Get your hands on some real, vinegar-free hot sauce. Like Tapatio. It's delicious, and it's the only hot sauce with a picture of my dad in a sombrero.

Yeah, sorry. Experiment or not, the end result is uninteresting.

Anyone else ever hear "Astroglide!" instead of "I'm so glad?"
