I've been following what Lightsail is doing for a while. Would you say the problems you face are more technical or deal-making in nature? In other words, is it more an issue of getting high enough efficiency in the energy recovery, or an issue of getting the technology into use? Or is it cost (since low enough cost makes deal-making easy)? Apologies if I am asking for too much information.
