  1. yo considero que es mas contaminante el consumo de combustibles solidos a lo largo de la vida del vehiculo, que la propia extraccion de metales como el neodimio, cerio o el lantano.

    es mas, la extraccion del petroleo tambien es sucia, creo que mas que la de determinados metales.

    el monopolio que ejercera china sobre estas tierras raras sera nuestro maximo problema.

  2. Great post! You see, I’m currently working on a blog post and, depending on where my writing takes me, I might just put a citation for this post in it. I hope you won’t mind if I do. Anyway, people all over are making their own takes on what makes for a great muscle building program/routine. The way I see it is that all the things that they are saying nay, preaching can be rolled up into one thing and that is having the self-discipline to follow-through with whatever it is that you are doing. Personally, I strongly believe that following through is the singular most important ingredient in attaining success, not only in bodybuilding/building muscles but in life in general. Once again, wonderful post. Keep it up! I hope you won’t mind if I look around your blog a bit more.

  4. Generally speaking, if only need the prototyping to measure the size of the product, there is no need to
    spray oil, then can save time to do exterior treatment,
    certainly can save cost.
    If need to make a lot of every product, then we suggest produce it by vacuum casting, the cost is lower
    than CNC processing.
    If the structure of the product is complex, hard to use CNC processing, and hard to control the size, we
    suggest adopt SLA. But the cost is much higher than CNC
    processing and vacuum casting.
    In a word, adopt different processing method according to your requirements, we can help you save a lot of
    cost.
    You need to provide IGS,PART,STP form 3D picture if need us to make prototyping, the best is the IGS form 3D
    picture. Also related requirements of
    after-treatment., such as color, surface effect,etc.Please login http://www.prototypingchina.net to know more about

  5. Vea pues y uno creería que todo es amigable con el medio ambiente, por ejemplo con el aceite de Palma, en Colombia hay millones de hectáreas plantadas con Palma de Cera y lo que ha demostrado con el paso del tiempo es que esta palma seca la tierra y su alrededor dejando a los cultivos aledaños sin o con poca agua evitando que su crecimiento sea lento o no productivo, además de esto por los químicos que usan para su mantenimiento, con el tiempo maltratan tanto la tierra que su recuperación para otros productos es muy larga.

    Saludos.
