Wind power
Wind power works—but only when the wind blows, only up to 59% efficiency, and only if you redesign the grid around it.
Physics that became politics, on a schedule nobody set.





Silicon Graphics built the first practical hardware-accelerated 3D graphics systems. Its Geometry Engine — designed at Stanford under ARPA — delivered ~6 million geometry operations per second. It pioneered scalable cc-NUMA architectures in the mid-1990s. But its reliance on proprietary MIPS and failed transitions to Itanium and Xeon eroded its position as PC graphics commoditised. It filed for bankruptcy in 2009.
