What we know from the AGM - Info from Storm_chasor, page-15

A number of points I’d like to add to @Storm_chasor great update.
1 the slab, there are options being looked at, the best is to pay slightly more to get a slab within a tighter tolerance. Maybe add a grinder attachment to the boom less likely but worth exploring. Finally they reckon they can loose any difference of 3-5mm over the 9 courses. So a big tick from me.
2 They are taking the IP security very seriously, even if someone in China reverse engineers their technology they have so many patents locked down it won’t be of any use outside China.
3 there are 2 trucks on the factory floor and assembly has begun. I’ll admit I was impatient we haven’t seen HX yet but again assembly has begun, the reason no time line has been given is because parts are being procured from around the world so one slip from a supplier causes a delay and we all loose our sh1t. A huge tick from me I’m glad they are focused on getting this right first time, just on that as well they have spent so much time digitally perfecting this there is a very low chance HX will not work
