The crux of the matter: sustainability
At this point, that of reducing emissions, we come to the heart of the matter. Because beyond the spectacular nature of these science fiction vehicles, in the real world there are other additional priorities and, furthermore, those of 30 years ago were not the same as those of today ”, explains Javier Ariztegui, product design manager at Repsol. In this way, in addition to being interested in driving flying or quasi-human cars, according to Ariztegui, we are also concerned that they are comfortable, efficient and safe, and, above all, that reduce greenhouse gases.
The mobility of the future, according to the experts, takes time, and from one day to the next it would be mathematically impossible for us to replace the current fleet of vehicles with an electric one. The solution would go through a ‘mix’ of options to reduce greenhouse gases. One of them, more immediate than electrification, is in the advanced biofuels, which reduce emissions between 65% and 100%, whose properties are similar to those of gasoline or diesel and allow the use of current vehicles.
These biofuels can be produced from waste, whether it is urban solid (food, paper, cardboard …); used oils (such as those used for frying in the kitchen); livestock (animal fats from slaughterhouses or food production remains) or agricultural and forestry residues. Conclusion: we do not put the garbage directly into the deposit as in ‘Back to the future’, but we are already able to turn that garbage into fuel and, in addition, respectful with the environment.
Again, if we go from fiction to reality, we will find the AirCar of the Slovak company KleinVision, which, in just three minutes, transforms into a kind of plane, spreading its wings and tail and then reaching enough speed to take off. It can also be driven by land. The vehicle, which is not yet on the market, can reach 200 km / h and its range is 1,000 km.
Uber, for its part, has already announced its next flying taxi service to decongest traffic in big cities. Uber Elevate will fly at a height of between 300 and 600 meters and will reach 240 km / h, it will have its own heliports and, attention, it will work exclusively with electric power (with almost 100 km of autonomy).
