  1. I don't want to subscribe to DW if i can't get this type of unique important documentary from time to time, sorry. I do like the story on the use of metal by-product to make concrete blocks for building construction. That will save a lot of cement and should be the way forward in the constrution industry from now on to save the planet from Co2 emissions...

  2. A great new industry for oil and gas producing countries in the middle east. A country like saudi arabia invests so much tech in converting sea water into useable water for domestic use, leaving behind tons of the salt that comes out of it. Investing its oil money in this new tech industry to produce batteries from salt could be a game changer. The world needs it, the middle east needs the money that comes from it...i think. idk
