Bloomin' Bloom Box
Several comments, none related to the reality/unreality of the Bloom box.
1. Ethanol sources: Lewis, surely you are aware that non-crop biomass production of ethanol is coming soon.
2. Electric grid losses are ~40%. If the Bloom box works at all, it need not be very efficient to do better than the grid. Being colocated with the consumer, it automatically has a 40% efficiency advantage, depending on the losses in the gas grid. What ARE the losses in the gas grid?
3. Again if the Bloom box works as advertized, gas need not be its only fuel. Certainly the vast herds of cattle on the Salisbury plain can be harnessed to supply much of it. Erm... Please ignore that last. Bloom claims the box can take in electrons and produce fuel (I'd like to see THAT!), perhaps completely changing the equation.
Otherwise, a good article, with a reasonable dose of scepticism. More power to you, Lewis!
