Revolutionizing Agriculture with Precision Farming

waterwheels, the most powerful prime movers of the early modern era, averaged less than 4 kW.

Fondé sur des outils entièrement dépendants des énergies conventionnelles, le monde moderne est à l’évidence – et en dépit des apparences – le plus vulnérable qui ait jamais existé. La disparition des énergies fossiles et électriques, qui tétaniserait tout le système et le rendrait en un instant obsolète, n’est même pas concevable. Ce sont en l’occ

The notion here is that when electricity is cheap, you use it to heat up some material. Then, when you need more electricity, you use the heat to generate power via a heat engine. This can work at 50 or 60 percent efficiency, which isn’t bad. Engineers know about many materials that can stay hot for a long time without losing much energy; the most

part by building coal-fired electric plants very cheaply. Chinese firms drove down the cost of a coal plant by a remarkable 75 percent.
