Green Flops: Why Some Promising Cleantech Ideas Didn’t Work Out

The video discusses the challenges faced by innovative companies like Solyndra and those in the biofuel industry. Solyndra's attempt to innovate in the solar market was thwarted by falling polysilicon prices, making their product uncompetitive. Similarly, biofuel companies struggled with high production costs despite achieving their technological goals. The video also covers the high costs associated with solar power towers, which, despite their functionality, remain economically unviable.

Discuss the impact of polysilicon prices on the solar energy market.

What factors contributed to the failure of solar power towers despite their initial promise?
