Have you ever wondered how much CO2 a bus? At the traffic lights they stay with the engine running, they make numerous races around the city and they are very busy! Driving is characterized by continuous braking and acceleration as they move in an often congested urban environment. One solution could be the electric buses: they are not subject to extraordinary autonomy as the routes are planned and consumption largely controllable. Above all they do not produce Polluting emissions poisonous.
The bus they complete a fixed, predetermined number of kilometers every day. The route is always the same so it is easy to program stop and travel times. In this perspective, an innovative system has been tested in California energy saving in the name of sustainable public mobility.
It is about electric buses that through a system of "fast charge“, Connected to the roof of the public transport, allows the transfer of energy in a very short time. L'bus recharges in 10 minutes at each terminus stop, sufficient time to allow the driver to stretch and stretch a little at the terminus between one route and another. Such fast charging is allowed by lithium titanate batteries. In this way the bus recharges several times in a few minutes without running into problems electric autonomy.
The service is managed by Foothill Transit, the local operator who received $ 20 million in funding to develop the project and to plant a fleet of an additional 9 buses. According to the first calculations, isavings they are 600,000 dollars in the useful life of a vehicle of which 500,000 are for diesel and 100,000 for maintenance and labor. L'electricity to recharge the buses it costs a few cents per kilometer. The savings are obvious: 18 cents per mile, against 1 dollar per mile Diesel vehicles!
In Italy, what is being done with a view to sustainable mobility? Hopes are pinned on the ZET project, which envisages the first electric motorway in Italy.
