A DIY E-bike Conversion on the Cheap

Cars That Think

At the time, e-bikes were still rather exotic, at least in the United States, so it seemed worth the expense and effort to build my own. Online discussions convinced me, however, that this is the expected behavior when commanding a motor to maintain a fixed amperage in its windings (thus applying constant torque) while under little load.

BNEF ups forecast for global investment in stationary energy storage, sees majority of capacity likely to be grid-scale

Green Car Congress

The report goes on to model the impact of this on a global electricity system increasingly penetrated by low-cost wind and solar. In the near term, renewables-plus-storage, especially solar-plus-storage, has become a major driver for battery build.

Discover Le Havre, Where Impressionism Was Born

Baua Electric

This year, France is celebrating the 150th anniversary of the movement. It is sending 178 other works to more than 30 museums throughout France. MuMa, as it is called, has arguably the most important collection of Impressionist paintings in France outside the Musée d’Orsay ( Rouen’s Musée des Beaux-Arts makes the same claim).
