			#Develop an explicit design for the collector tube ($500)
			##Source materials

			#Develop valving system for collector tube feedwater entry ($150)

	~~See [[OS2 Development Points]] for details.~~		#Develop digital fabriction of steam engine ($100)

			#Modernize said steam engine with electronic steam injection ($50 for valve and controls)

	~~The second point of development is the collector tube. We need an explicit design that addresses blackbody radiation, conduction, and heat loss from the back of the collector tube.~~		#Develop a matchins electrical generator ($150)

	~~The third part is collector tube feedwater. For the solar application~~, valving is a solution because is requires much less energy to operate than a feedwater pump – on the order of watts instead of hundreds of watts. This means that we’ll have hundreds of watts more usable power – not power that is fed back to water pumps. This valving solution needs to be creative, and may require several feed-in locations throughout the 60 foot long collector. Another company which is currently developing a solar thermal generator is also using valving for exactly the reason of lower power usage, ~~and indeed claims it to be its key to success - (used by another solar power system without a heat engine~~ (~~https://matteranenergy.us/Contact_Matteran_Energy.html~~)		#Integrate additional steam cycle components - cooling, pumping, preheating, superheating ($150)

	~~The 4th part is the steam engine. These are available at $1370~~ for a 5 hp engine suitable for our purposes. Our goals is to produce these from scrap metal by casting and machining with digital fabrication assist, for an engine that costs $250 to produce. This is very ambitious, but given that the scrap steel required for this costs only $10, we think this will be feasible. Ball bearings for this engine are the most expensive part, at $20 each – or about $80 total.		See [[OS2 Development Points]] for details.

	The fifth development point is electronic control for the steam engine. The above steam engine is simplified with a major modern advancement – electronically-controlled steam injection. Arduino-based electronics will control a valve that controls the steam feed to optimize steam usage. This is not only a simplification, but also an efficiency boost. The catch is that such valves cost $300 today, so we will be developing an open source solenoid valve at a cost of materials.

	The sixth improvement that we have to do is a dedicated electrical generator that can be coupled directly to the steam engine for electrical production. We need a dedicated generator optimized for our application – so we need to opensource the electrical generator as well.

	~~The seventh development point for the solar power generator is steam cycle integration – from steam injection~~ to the ~~collector tube~~, to ~~feedwater pumping up to~~ the ~~steam injection part,~~ to ~~cooling and heat recovery. This completes the project~~.		Prior to the Convergence, we need to have the components to be tested.

	~~Prior to~~ the ~~Convergence~~, we ~~expect components to be tested~~ and ~~in working order~~. ~~In particular~~		[[OS2]] will include the synthesis of the system into a working whole, as we will watch the steam engine spin and power being generated from the generator head.
