Das Sahara-Projekt (1993)

A miniseries about a scientific project trying to develop and exploit efficient solar power. The group members have the normal family and funding problems to concern them. But more sinisterly, they have to contend with energy companies who need them to fail and are too happy to help them along their way, mysterious business concerns who want to pump money into the project but for unknown or dubious reasons, and, worst, terrorists and murder attempts.
