I think the niche they have in mind is "server farms". The Google/Facebook/whoever modern datacenter design that uses free air cooling and hot/cold segregation and whatnot to get down to a SPUE of 1.15 doesn't leave much energy to cut outside the server. Getting rid of the fans is a ~ 15% win. Whet
