Solar Power beats all biofuels for cars

The carbon footprint life cycle of biofuels is far worse than Solar Power charged battery-driven cars. It makes sense to have an electric vehicle and solar panel your garage to charge it up.

PV conversion ... has lower GHG emissions throughout the life cycle than do cellulosic biofuels, even in the most optimistic scenario for the latter. "The bottleneck for biofuels is photosynthesis," Geyer says. "It's at best 1-percent efficient at converting sunlight to crop, while today's thin-film PV is at least 10-percent efficient at converting sunlight to electricity.

Finally, while cost was not a key component of the study, Geyer says, "The cost of solar power is dropping, and our quick calculations suggests that with the federal tax credit, electric vehicles are already competitive."

What does this mean for the future?

"What it says to me is that by continuing to throw money into biofuels, we're barking up the wrong tree,"...

Pope's 'exorcism' caught on film video

No, I don't support 'traditional' marriage because there is no such thing. I support heterosexual and same-sex couples marry each other legally , yes.  'Traditional' marriage promoters largely do not believe that heterosexual women are co-equal to their husbands.  Their only purpose in 'traditional' marriage is to sexually satisfy their husbands if they can and raise children and do all…

My first funeral as an atheist

Posted by Two Cult Survivor on May 21, 2013 at 11:30am 0 Comments

I posted the bulk of this on another thread, but wanted to add some context separately.

I finally confronted my faith and embraced the fact of my atheism late last August, 2012. Days after I revealed my "epiphany" to a few friends who knew me from another message board, my sister died from Lou Gehrig's Disease (which pissed her off because she hated catching a disease from someone she never f---ed).

THAT was my sister, understand? She was a beautiful, life-loving, potty-mouthed…
