Various clean energy moonshots at X have hit roadblocks, including Makani kite project
Generating energy by flying a plane-like vehicle with propellers, one of X’s oldest clean energy projects is facing stiff competition from the falling price of existing green energy sources. As a result, Alphabet’s support of Project Makani has fallen since its 2013 acquisition, while the same fate befalls many of the research lab’s other climate change-fighting moonshots.
