Global warming is amplifying and beating records every day. It is happening due to many reasons for which we can sometimes act, sometimes not. Nevertheless, for years now, Tesla’s name is linked with a game changer if it comes to companies that are pioneer in new clean way of living.
Tesla’s cars, Tesla’s batteries, Tesla’s solar roof. You have probably already heard about those products. Changes made thanks to Tesla are becoming more and more appreciated all around the world and making changes that are good for our planet.
However, Tesla wants to go one step further. After delivering more than 76,000 cars in 2016 worldwide and implementing many superchargers (Tesla’s “gas” stations to “refuel” their cars), the company from California presented on the 16th of November it’s way to look at the road transports in the next years.
Semi, is a fully electric truck with a range of 300 to 500 miles (480 – 800km) when it is completely loaded and on a highway at legal speed, not very impressive in comparison to up to more than 2000 miles (3200 km) range for a diesel truck, but it can be charged thanks to a megacharger and have more than 400 miles (640 km) range after 30 minutes of charge, all of that being 20% less expansive than a normal diesel truck. Tesla states that “Semi is the safest, most comfortable truck ever. Four independent motors provide maximum power and acceleration and require the lowest energy cost per mile”. With its 4 electric engines, the 40 tons machine can accelerate from 0 to 95km/h in less than 20 seconds and uses all the new technologies that are already implemented in Tesla cars for the security.
Tesla also worked a lot on the aerodynamics of the truck, being the black spot of the trucks we are used to know. The drag coefficient (cd) went from 0,65-0,7 in a normal truck to 0,36 in the semi. In comparison, the newest Bugatti Chiron has a cd or 0,38. The economy of this truck compared to a “normal” one could exceed 200,000$ in fuel savings through this technological solution and electric engines.
In addition, according to CITEPA, 7,9% of Co2 emissions are generated by Diesel trucks. Thanks to this new truck, those emissions could decrease significantly.
But on the other hand, according to UCSUSA, the production of such kind of cars/trucks, generates more carbon emissions than to build a conventional one, moreover, the electricity for this car has to be produced in some countries thanks to renewable energy, but sometimes, it is only possible with electricity from a nuclear power station or fossil power station, so in this case, the green side of it would be even worse than a heated engine.
In my opinion, the Tesla Semi is a good idea, thanks to many innovations, and a totally new way of looking at road transportation it is really something that can be good for the planet and for people working in this field. Nevertheless, this solution only makes sense if it is made with a good mind, in other words, being sure that it will be used with renewable energies, with a possibility to recycle them and to have a good warranty for batteries.
