RE:RE:Is it TRUE Bill Gates is paying....Excellent information Trevor!! U-Tube clip indicates they can make a polution free cement but it takes a lot of steps, materials and processes, all which have some polution related consequence. Hudson's anorthosite is pure.... no dangerous elements, no lengthy expensive processes. Just add the acid solution mix .... basically one simple step and you eliminate 8% of global carbon pollution. This is the cheapest and most simple solution because the Hudson material is so pure and BAD CHEMICAL FREE !!! The U-Tube product can never come even close to the cost/performance comparisson of what Hudson has! Go Bill go !!! Bill Will be a part of the best solution. Not a part of a poor interim step. If the Gates Foundation uses Hudson cement just on Gates Foundation construction the stock goes to a "Buck" !!
