PRODUCT →DEVELOPMENT STRATEGY
What the Wong Premise Can do to Strategy
Decades ago, the premise for product development was that companies had to choose between cost, quality and time-to-market!
Proponents of this premise would quip: "we can only have two, " while cynics said, "maybe that is only one." One leading management "guru" book confidently said that companies had to make the "winner's choice about which one(s) to be good and use as a competitive weapon.
The flip side of such faulty think was to identify which companies were worst at, and then use the only desperate measures they could think of, like substituting cheap parts, low-bidding, and OffshorIng , which is known to waste 2/3 of product development resources!
Then 30 years ago, the first edition of author's DFM book came out with the sub-title: Optimizing Cost, Quality, and Time-to-Market" (see cover at right). And this site and the latest 2014 book shows how to do all that. →
The General Strategy to avoid an either/or Dilemma
STRATEGY TO DESIGN THE BEST EQUIPMENT ELECTRONICS & CONTROLS
This strategy assured the best customer satisfaction at the lowest cost at the highest quality at the fastest time to stable production
For example, a vast array of the following proven off-the-shelf modules are readily available:
Ultra-Low-Cost frames can be built can be built automatically on ordinary CNC machine tools working in flexible cells using Cellular/Flexible Manufacturing principle and then be assembled rigidly and precisely by DFM principles.
Again, a key element to success is to implement this
STRATEGY FOR CONCENTRATED SOLAR POWER
The conventional premise of renewable energy is on generating electricity, which waste 3/4 of input energy for solar power and 2/3 waste for fossil fuel plants and wind power . For reference, fossil fuel energy production also wastes two-thirds of consumed energy.
The premise for an Optimal Solar Strategy should be heat (nearly 100% efficient), not electricity (now at only 25% efficiency); see comparisons below.. -- Plus serious implications for scalability & point #5 below.
Current Solar electricity is inherently can not be scaled; Solar heat can!
Electricity from any renewable
power plant can not be stored for
use at night,
Electricity is generated by steam turbines and reducing speed to to make electricity at no more than 25% efficiency. At this efficiency, no form of solar "energy" should ever be use to make heat, which can be generated directly at four times the efficiency of electricity. Polity makers and environmental groups should strongly discourage using electricity to generate heat, when solar alternatives are available, , starting with going back to clothes lines!
Heat. Use virtually all solar energy directly as heat, from smaller fields, to provide:

Design for Lean Manufacturing
MAXIMIZING SOLAR HEAT FOR INDUSTRY AND AGRICULTURE
Concentrated Solar Heat (CSH) needs to be planned and designed to maximize the amount of industrial heat that comes from the Sun. Here is what the strategy that CSH industry needs to pursue:
I. Existing Industries: The U.S. Energy Information Administration report on "Energy use n industry" (updated August 2021) listed yearly energy consumption for the industries tabulated below without the unidentified "Other" categories and the category called "Petroleum and Coal."
The table below cites the yearly consumption of "fuel" (primarily by burning natural gas, all of which could be replace by reenables as recommended on this site) in each category as a fraction of the total of these five categories:
All of these, except Food Processing, are grouped together into clusters,
which would have room for solar heat fields (like heliostat mirror arrays used
in Concentrated Solar Heat fields, as long as they are compact enough to
get their heat into all processing users.
II. Agriculture and Farming would benefit greatly from
concentrated heat generation with over-night storage for local
desalinization, crop drying and pre-processing, "green" fertilizer
production, bio-mass fuel production from agricultural waste, building and
barn heating even all night, and emergency crop heating, without burning fossil
fuels. And, as mentioned below, Highly Concentrated Solar Heat
will be able to generate zero-carbon vehicle fuels for tractors, combines,
and to ship crops and fertilizers.
III, Promising Potential for Solar Heat
IV Products made from CO2
Providing the heat to make products from carbon dioxide (a searching on that phrase gets 86,ooo,ooo results!), Not only would this "capturer" CO2, but it also makes useful products to reward the effort. Five product categories listed by GreenBiz are; carbon nanotubes, carbon fiber; Nanoparticles for plastics, concrete and coatings; Bioplastics; Methanol; and Chemicals, bio-composite foamed plastics.
OPTIMIZING RENEWABLE STRATEGY FOR TRANSPORTATION
Of all sources of green-house gases (GHG), transportation has worst combination of solution importance and urgency combined with solution difficulty, cost, impact on our lives, jobs, impace on and the economy
Here are the factors that affect this ratio from worst to best:
STRATEGIC ANALYSES AND
STRATEGIES TO PURSUE
Emissions. (Point #1): projects that emissions from conventional sources continue to resist attempts to reduce emissions at the source (or capture, transport, and store the pollution.
Strategies to pursue: To achieve the goal of "no net emissions from vehicles plus their sources," we will need to eliminate the all emissions that supply these low/no emission vehicles or else their real benefits will be cancelled out.
Fuel Sources (Point #2): The low efficiency of fossil fuels makes them three times worse than perceived with respect of raw material mining and extraction, and their environmental impacts and costs .
Strategies to pursue: This needs
to be taken into account for any transportation strategy that depends on this electricity
which is inherently wasteful of source energy.
Charging / Refueling: (Point #3): n addition to the fuel distribution conundrums mentioned in Point #3, lack of system scalability will lead to shortages, which are becoming the industry's biggest challenges when they are being asked to become carbon-free.
Strategies to pursue now:
Scalability needs to be understood and products and their production
systems need to be designed for that, as taught in Section 4.8 (IN
THE 2020 DFM book) and at Scalability
to greatly increase production volumes quickly
Strategies to pursue: The overall system strategy needs to be prioritized to allocations panels which are inherently not scalable, (as shown in Section 18.104.22.168 in the 2020 DFM book). Recent news cites supply problems brewing for high-performance electric motor that are designed around rare components (actually made from "rare Earth" elements) which are warned against in Section 3.9.7. Here the advise is to design in adequate space for readily available magnets.
New mobile fuels (also in point #4) may be produced in large, remote factories (like current refineries.
Strategies to pursue: Renewable energy could leap ahead on energy distribution (point #4), by (a) developing more compact energy source utilizing the unique Precise Assembly design principles, that could be more plentiful and be located closer to users, and, (b) developing fuels that can be trucked to existing or new fueling stations.
Energy storage (Point #5): Un-synergistic thinking allows using valuable (and some predict scarce) batteries to correct one of the biggest shortcomings of both PV solar panels and wind power: storing energy when the sun doesn't shine of when the wind doesn't blow.
Strategies to pursue: Systems
thinking would advise that battery usage should now be prioritized for (1)
storing roof-top PV electricity storage and (2) the electric vehicles themselves, as
discussed in Section 22.214.171.124 in the 2020 DFM book. A
related prioritization would also avoid using batteries for wind power,
which may ironically might be thought of as a way to power electric
vehicles. Instead, systems thinkers should insist that wind energy
also be stored without needing batters, for instance, pumping water up
high enough to generate electricity through the same generator, r, when s not
blowing). A clever, integrated solution uses the actual tower
structure to hold the pumped water.
Conversion Costs : Ignoring these or other adaptation strategies may incur overwhelming costs to replace all vehicles when auto factories can’t even find enough parts to keep their plants open. Current decision-nJUBF needS to immediately start prioritizing the allocation of PV solar panels which are inherently not scalable, (as shown in Section 126.96.36.199 in the 2020 DFM book). Rather than accept the status quo or an obvious but sub-optmal "solution," to the first half of these points, consider all of these "Strategies to pursue.."
Conversion time (Point #7): The more urgent is the need for change, the faster its completion is needed from the first half of Point #7 and all these other points above.
Strategies to pursue. Complete meaningful
change quickly and getting the fastest results will depend on: optimal
strategies (summarized on this page); Concept Breakthroughs (Section 3.8.3 on Designing
Half-Cost Products in the DFM book) like adapt existing internal combustion
Solution Viability (Point #8), consider the slogan on the back cover of the
new 600page DFM book: "Achieve any cost goals in half the time and
achieve stable production with quality designed in
right-the-first-time:" (DFM book slogan). (jFor

A solar furnace concentrates enough sun rays reach temperatures high enough to produce solar hydrogen, sometimes called green hydrogen.
Solar furnace laboratories have generated hydrogen and oxygen, sometimes in separate chambers which could be generated on a continuous basis.
The previous section on "Optimizing Renewable Energy Strategy for Transportation" showed mow much low-cost, scalable supplies of clean hydrogen could help all the strategies presented for transportation.
Solar furnaces have been making hydrogen in many ways from Highly Concentrated Solar Heat (HCSH)
Also, hundreds of R&D projects have been working for decades to perfect a category called Direct solar water-splitting. The simplest and most commercializable approaches require (1) very temperatures and (2) very low cost. The highest temperatures come from very high concentration of sun rays , that can be achieved using Precision Assemblies and accurate tolerances for large structures, which us summarized in the next paragraph. Very low-cost can be achieved with the just-published "Half Cost Product Development" (Section 3.8 in the 2020 DFM book) which cam save nine cost categories half the cost to ten time less!
The foundation for what is needed is Design for Manufacturability (see dozens of DFM articles); DFM guidelines including : Availability designed in (see Sections 3.8.3, 3.9.7 , & 4.6.3 in 2020 DFM book); Tolerance Strategies (in 17 sections; 9 guidelines, and two figure in the DFM book; How to avoid cumulative exponential degradation of quality and performance, e.g. for hundreds of thousands of heliostats mirror trackers, which now could not get enough chips for that (see Figure 10.2 and Section 3.3.11 on Concept Simplification in the DFM book); and Half Cost Product Development (Section 3.8) saving cost at the high end of its range: 10 times less costs or better,
A manufacturable solar furnace that can concentrate sun rays 6,000 to 10,000 times will need How to Design Precision Assemblies, which has been provided for all the clients with blue hyper-links on the author's client page.
The following section will present how solar hydrogen can help other industries.
INDUSTRIAL USES FOR HIGH TEMPERATURE
As pointed out earlier, 60% of industrial and residential/office energy demand is heat.
In order to supply renewable heat to where it is needed, the sources will need to close by. Fortunately, highly concentrated reflector systems can be located next to or on top of factories or office, apartment buildings, and even fueling stations.
Fortunately, very high solar concentration ratios, can be compact enough that (a) as many as are needed can be located next to the proverbial "blast furnace" application and (b) these can be designed to be light enough be supported by roofs.
Further, the much higher "sunlight concentration ratios" means that in northern latitudes or on cloudy days, more "filtered sunlight" will get though to a wide range of most solar heat users.
CONVERTING HEAT DIRECTLY TO ELECTRICITY
In addition to providing high-temperature heat for industry and clean fuel generation, high-temperature solar heat sources can also generate electricity directly from heat with no moving parts at higher efficiencies than the steam turbines currently used by Concentrated Solar Power (power towers) .
Next generation thermionic generators will convert heat to electricity at 40% efficiency which is twice as efficient as all solar power today.
And, carrying forth commercialized versions of the best of solar power will provide effective heat storage in proven molten salt tanks, this time a lot of heat at very high temperatures, which will ensure even more electricity production
Unlike the case of steam turbines, (with no value of heat over the boiling point of the working fluid), temperature actually does matter for thermionics since its premise is that "the larger the temperature difference, the more electric current is produced and the more power is generated."
And in colder regions, the colder ambient temperatures would extend the lower end of the temperate differential that determines thermionic performance. That may compensate for a lower high-end temperature in higher latitudes or more prevalent clouds.
CONCLUSIONS : Strategy for:
Highly Concentrated Solar Heat (HCSH)
The end of the advanced strategy page on this site shows how to commercialize the "solar furnace," which concentrates sun rays several thousands times to produce "blast furnace" temperatures. High concentrations can be achieved by design with the overall strategies presented in the page How to Design Precise Assemblies and optimal tolerance Strategies (in 17 sections; 9 guidelines, and two figure in the 2020 DFM book Such a low-cost design would be scalable and would be able to:
(a) provide 60% of all of the energy demands for industry, which is in the form of heat
(b) evolve to use higher temperatures (not valued in steam based generators) to convert abundant solar heat directly to electricity at twice the efficiency of all current solar power (PV or CSP) with no moving parts and
(c) make solar hydrogen as the ultimate clean transportation fuel, Which can be "burned" in existing vehicle engines (with only water vapor as the "exhaust") and be able to switch over to the more expensive gas in the same old gas tank if the H2 tank might be close to running low-- until the quick-filling fluid fuel can be trucked in (pr generated locally) and a new "gas" can be added to our existing network of gas stations.
