Solyndra is one of the most hyped solar starups which has managed to raise $1 billion in funding and coming out with surprisingly little for the money.Not only did it postpone its IPO but also shut down its first factory as pricess keep diving faster than it can cut costs.Brightsource Energy on the other hand seems to have a brighter future with its unique CSP technology.Also with backers like Alstom and Bechtel,it has the heavy engineering support to construct the massive 392 MW plant.Note other Solar Thermal startups like Ausra and Soliel Systems were bought up by giant engineering conglomerartes Areva and Siemens.Brightsource along with eSolar remain the only pureplay CSP companies still surviving.
