imagine it...
you could manufacture the machines in abandoned factories, then deploy them to all night warehouses. you'd generate good jobs creating, upgrading and maintaining the machines, which would produce produce essentially at cost. and, given that ontario's grid is able to produce so much clean energy for almost no cost, we could potentially become a major export market for things we don't already export.
but, the market won't do it on it's own, it needs help from government to do it.
