Trevor Blackwell warns that MIT's new motor-free artificial muscles run at 1% efficiency, requiring 100x larger batteries

The fibers contract silently using electrohydrodynamic fluidic pumps.

@yishan Meh, there are similar claims by various labs every few years. AFAIK, none of these solutions ever made into the production systems.

@yishan Read the fine print before giving up on motors. Efficiency of the pumps is around 1%, so you need a 100x bigger battery.
