Prius gets a low speed sound for the blind (video & audio)
At parking lot speeds, electric & hybrid cars are almost silent. A risk to the blind, partially sighted & simply inattentive has been suggested. Legislation has been mooted. Toyota is doing something about the silence of the Prius at low speeds:
To date, there is no suggestion of doing anything about near-silent internal combustion engined cars.
Researchers increase charging rate & capacity of lithium ion batteries by a factor of ten
Yet another new battery which promises much. Reserving judgment for now.
+ 10 x capacity of competition
+ 10 x charge rate
- Relatively rapid deterioration of charge capacity with use
+ when the capacity has halved after a year of use, it's still five times better than the competition
