Civil War soldiers used the dye from purple pokeberries to write letters home. Now, the bright-colored weeds are being used for a far more modern purpose. Researchers at Wake Forest University’s Center for Nanotechnology and Molecular Materials created low-cost, fiber-based solar cells that work more efficiently when coated with a layer of pokeberry dye.

    What about me?!?! I’ve lived without electricity for several years now trying to save up enough money to get solar panels and yet I am still forced to run a diesel generator all day and all night long. Everybody wants to send this technology to deveoping nations. HELLO, I am right here in the same state!! I didn’t decide to live off-grid, I was forced to after my real estate agent lied to me about power being on this property and I spent every dime I had on this house. So here I sit, emitting CO2, hoping to one day have enough money to change the situation. Oh well. I hope they like those solar panels.
