Innovations : la plus petite voiture électrique au monde !

Article publié le 21 novembre 2011

Je mesure un milliardième de mètre, je suis 60 000 fois moins épaisse qu’un cheveu et mes parents sont néerlandais… Qui suis-je ? Une nanovoiture bien sûr !

Innovations : la plus petite voiture électrique au monde !

Le plus petit véhicule du monde vient de voir le jour aux Pays-Bas, grâce à des recherches dirigées par l’EMPA et Ben Feringa de l'Université de Groningen. Une voiture nanométrique mesurant un milliardième de mètre dont la composition est simple : quatre roues faites de quelques atomes, rattachées à une molécule centrale. Impressionnant !

 

Son utilisation est pensée à des fins médicales et pour la recherche en nanotechnologies. Des éléments à l’échelle du nanomètre seront transportés grâce à l’énergie émise par un microscope électronique qui lui permet de se déplacer.

 

A la découverte d’un tout petit monde électrique

 

La nanovoiture est le résultat de plusieurs années de recherches. Son évolution n’a de cesse de repousser les limites de la nanoscience.

 

En 2006 déjà, les nanovoitures étaient dotées d’un moteur à énergie solaire dont la technologie pour se propulser était la même que ce dernier modèle de Ben Feringa : « l’effet tunnel ». Cet « effet tunnel » désigne l’utilisation d’un moteur qui, exposé à la lumière, se met à tourner et propulse le véhicule, comme une roue à aubes.

 

Et au-delà de l’automobile, que se passe-t-il dans le nanomonde ? Voici un aperçu des nano-inventions les plus insolites :

 

- une cape d’invisibilité mise en place à l’Université du Texas, à Dallas : elle permet de cacher un objet visible.

- une puce cognitive capable de simuler certains processus du cerveau humain, pour des ordinateurs capables d’apprendre et de supposer comme nous.

- un tissu conducteur d’électricité,qui serait par exemple utile, intégré à des murs de bâtiments sismiques.

 

Voici la vidéo montrant le déplacement de cette nano-voiture électrique en vue latérale :

C’est tout de même assez remarquable ce que l’on peut faire désormais de nos jours ! La technologie, et notamment automobile, avance et cela s’accroît de jour en jour. Après, le seul problème concernant ces voitures sera le prix. Même dans un futur proche, qui pourra à leurs débuts acheter de telles perles ! Parce que prendre une voiture pas chère de nos jours est difficile maintenant ! Qu’on se le dise !
