I just heard that CoalTek (which has the worst Web site of any venture backed company that I have ever seen), has raised an additional $33 million in its C round. The investment deal was led by Lightspeed Venture Partners, but also included participation by Warburg Pincus, Draper Fisher Jurvetson, DFJ Element and Braemar Energy Partners.

Some big names in these parts.

CoalTek is a Georgia-based developer of clean burning coal technology.

Thanks for the tip.
