در قلب موتورهای الکتریکی مورد استفاده در خودروهای الکتریکی همواره از #خاکهای_نادر به عنوان هسته مگنت و آهن‌ربای دائمی استفاده میشده و این وابستگی باعث شده است که همه تولیدکنندگان خودرو، چشمشان به چین بعنوان بزرگترین فروشنده این مواد استراتژیک باشد./۱
محض اطلاع ۹۷ درصد خاکهای نادر جهان از چین تامین می‌شود و‌ چین از ۲۰۱۰ صادرات ان را محدود کرده است که هم قدرت‌نمایی کرده باشد و هم انحصار را تقویت کند. این موجب افزایش ۷۵۰درصدی قیمت #نئودیمیوم و ۸۰۰درصدی #دیسپروزیوم شده است. ولی این عناصر اونقدر هم نادر /۲

نیستند و اتفاقا معادن زیادی دارند ولی پروسس انها بخاطر رگولیشن سهل‌گیرانه محیط‌زیستی و ارزانی نیروی کار فقط در چین انجام میشود. با اینحال همه کشورها متفق‌القول هستند که این انحصار باید برداشته بشه وگرنه حیات و ممات برخی صنایع در کنترل چین خواهد بود. /۳

1/ The world is changing right in front of us; never before has change been as palpable. Most if it is being driven by technology which seems to be disrupting each and every domain. The obsession with technology driving progress to the exclusion of everything else is a bane.
2/ While it isn't a good idea to ignore technology, especially those that actually improve human life and condition, including those that make decisions faster and more accurate and those that make life safer and longer, one-sided technology growth will do more harm than good.
3/ Applying technology in context of people and environment must take precedence over speed and scale. Holistic design of solutions and services in individualized moulds is the path. Because the age of average is done and dusted. The factory model of #education must be disrupted.

1/ The rebuilding of Japan post the horrific atom bomb, fuelled the design philosophy to create a disposable culture. India however, remained largely unaffected. (Exception: City culture is homogenous worldwide) en.m.wikipedia.org/wiki/Throw-awa…
2/ India context— Reuse is seen everywhere. Repair and recycle continues to be the norm. "Wasting" is a foreign sensibility and throwing away things doesn't come naturally. The feel-good of keeping old stuff is deeply embedded in the collective consciousness.
3/ Design drives all change in terms of materials, processes of manufacture, fashion, trends... actually they're deeply intertwined and highly interdependent. Responsible design values come before economic compulsions at individual, company, industry and societal levels.
