Impressão 3D, aprendam como é. E uma Scooter de levar para o Comboio.

"-O que devo escolher?
 -Qual é a diferença?
 -Como posso fazer isto?" 

Ora, para quem faz perguntas sobre Impressão 3D, basta verem este vídeo do Jon Cantin, para saberem o suficiente para darem um passo em frente, e escolherem as vossas Máquinas:

Para além de várias tretas sobre rodas, que aparecem e desaparecem, há muita boa ideia, e es
ta é uma delas, uma espécie de Trotinete-Scooter, que é feita para Estradas e condições  reais, a sério, e que se pode levar para o Comboio, e isso é que é necessário, para gente real, no dia-a-dia:

Folding e-scooter to MUVe into production by end of 2013

Paul Ridden

If you need to cut across town, sliding behind the wheel of your car is not always the most practical or quickest way to get from train station to office, office to gym, or gym to juice bar. While public transport serves most inner cities well, the thought of zipping quietly and effortlessly through the thronging masses is one that has great appeal. If you can just collapse your vehicle down to a fraction of its size at the end of your journey, all the better. Such is the case with a soon-to-be-released three-wheeled, stand-and-ride electric scooter named MUVe, which transforms into a suitcase-sized trolley between rides.

O primeiro passo foi dado, com este método de criar Células Solares usando um vulgar Forno Micro-Ondas!




Making solar cells with a kitchen microwave

Jonathan Fincher

For most people, experiments involving a home microwave typically don't go much further than inflating a marshmallow like a balloon or reheating leftovers in plasticware – both with messy results. For metallurgists though, microwaves are sometimes employed to efficiently process metals, which is how researchers at the University of Utah found themselves using a secondhand kitchen appliance in their lab. Their resourcefulness paid off recently, when the team discovered a method for creating solar cell material with just a few basic ingredients and an old microwave.
