	#'''Materials Cost Reduction''' - see '''[[Seed Eco-Home Materials Cost Reduction]]''' - $45300		#'''Materials Cost Reduction''' - see '''[[Seed Eco-Home Materials Cost Reduction]]''' - $45300. Includes lumber, CEB, 3D printed parts, and solar concrete.

	If the current cost is $60k for materials for a 1375 sf 3 bed 2 bath home with 6kW photovoltaics, we can slash this cost to $10k with open source machines and materials. '''Total Savings in an Open Sector Enterprise are $49640'''.

Doable readily for unstabilized block if house has overhangs for moisture proofing, or a skin over the CEBs such as metal barn siding. Otherwise requires soil conditioning machines for mixing cement into the soil. Both are viable. But CEB is damn hard to do, so it's not as high in the priority list as 3D printing, which is exotic, and lumber - which is easier to build with.

	##Should we invest in pellet-based printing? Not favorable for large clusters - as extruders are $500 instead of $50 such that a 12-printer cluster gets expensive. Advantage is one less extrusion - doubling plastic recyclability.

	#'''Photovoltaics Manufacturing''' - currently cost is 20 cents per watt, as low as 7 cents from china. If we assume $100 for a 500W panel, it is hard to beat but we gain in recyclability and lifetime if we design the PV panels to be recycled or building-integrated. With open source automated production, we can transition such manufacturing from gigafactories to distributed megafactories.		#'''Photovoltaics Manufacturing''' - currently cost is 20 cents per watt, as low as 7 cents from china.

With open source automated production, we can transition such manufacturing from gigafactories to distributed megafactories. This is feasible because the starting material is sand, and [[Upgraded Metallurgical Silicon]] is an interesting route.
