Growing Citrus in the Snow

Posted on May 27, 2018  Comments (3)

The system uses the constant ground temperature 2.5 meters (8 feet) below ground to heat a greenhouse. The underground-temperature on his farm is 11 degrees (52 degrees Fahrenheit). Other nearby areas range from 9 to 17 degrees (17 is near a hot spring).

Just circulating air through 64 meters (210 feet) of tubing buried 2.5 meters underground is enough to allow citrus and other plants to thrive. Selling at local farmer’s markets brings in a very high profit for farmers that can grow and sell locally.

Using the power of the sun to grow and the constant ground temperature to keep the air warm enough creates an opportunity to grow all year round. The same principles can be used to cool down indoor temperatures in very hot locations near the equator.

Due to the controlled environment growing organically is easy so that further increases the payoff for this type of farming.

The cost of the system can be as low as $25,000 if you have access to a backhoe to dig the trenches for the air pipes and can do much of the labor yourself. That is the cost of just the heating systems for a conventional greenhouse.

I really like this type of intersection of engineering and business (as well as environment and health benefits – providing healthy local food) that creates value to society by using our knowledge effectively.

Open Source Seeds

Posted on April 26, 2014  Comments (1)

I find the current status of government granted patents to be very flawed, including patenting life.

Plant Breeders Release First ‘Open Source Seeds’

A group of scientists and food activists is launching a campaign Thursday to change the rules that govern seeds. They’re releasing 29 new varieties of crops under a new “open source pledge” that’s intended to safeguard the ability of farmers, gardeners and plant breeders to share those seeds freely.

Irwin Goldman, a vegetable breeder at the University of Wisconsin, Madison, helped organize the campaign. It’s an attempt to restore the practice of open sharing that was the rule among plant breeders when he entered the profession more than 20 years ago.

Good for them. This needs to be supported. The crazy practices of seed companies shouldn’t be legal but they pay lots of cash to politicians and the corrupt politicians (which seems to be an awful lot of them) write bad policy and encourage bad regulation.

Even those administrators taking control of universities have subjugated the search for knowledge and improvement to seek monetary gain instead of what the universities used to prioritize. It is a shame and those that have distorted universities so much should be ashamed.

Initial efforts that lead to the bad place we find universities in now were to promote the adoption of university research. To do so they partnered with business in sensible ways. Then administrators saw money was being made and turned the priority into making money and if that meant restricting the benefits to society of university research so be it. This has created universities that have lost ethical foundations and have destroyed a big part of the value universities used to provide society.

Silicon Valley Shows Power of Global Science and Technology Workforce

Posted on December 1, 2013  Comments (2)

Even with the challenges created by the culture in Washington DC against non-European foreigners the last 15 years Silicon Valley continues to prosper due to the talents of a pool of global science and engineering talent. Other countries continue to fumble the opportunity provided by the USA’s policies (largely a combination of security theater thinking and a lack of scientific literacy); and the strength of Silicon Valley’s ecosystem has proven resilient.

Software Is Reorganizing the World

an incredible 64% of the Valley’s scientists and engineers hail from outside the U.S., with 43.9% of its technology companies founded by emigrants.

5 things to know about the Silicon Valley economy

64 percent of college-educated professionals working in Silicon Valley science and engineering positions were born outside the U.S. as of 2011. That’s compared to the national average of 26 percent.

The Kauffman foundation’s recent study America’s New Immigrant Entrepreneurs: Then and Now shows evidence the anti-global culture in Washington DC is negatively impacting the economy in the USA.

The drop is even more pronounced in Silicon Valley, where the percentage of immigrant-founded startups declined from 52.4 percent to 43.9 percent.
…
The Immigrant Exodus: Why America Is Losing the Global Race to Capture Entrepreneurial Talent, draws on the research to show that the United States is in the midst of a historically unprecedented halt in high-growth, immigrant-founded startups.

… launched a website — ImmigrantExodus.com — as a resource for journalists and a voice for immigrant entrepreneurs.

As I have written for years, I expected the USA’s relative position to decline. The huge advantages we had were not sustainable. But the very bad policies of the last 15 years have negatively impacted the USA. The only thing not making the results much worse is no strong competitors have stepped into the void created by the policies of the last 2 USA administrations. It isn’t easy to create a strong alternative for technology startups but the economic value of doing so is huge.

The USA has created the opportunity for others to grow much faster, now some just have to step into the void. Will Brazil, Norway, Korea, Chile, Malaysia, Finland, New Zealand, Singapore, Germany, India… step up and create conditions for entrepreneurial scientists and engineers? Each country has been doing some good things but also continue to miss many opportunities. Some countries also have more challenges to overcome – it is much easier if the economy is already rich (say in top 20 in the world), speaks English, has a strong science and technology workforce… The innovation stiffing legal system in place in the USA is absolutely horrible and presents a huge opportunity to anyone willing to stand up to the USA’s continuing pressure to force countries to burden themselves with equally bad (or even worse) policies (such as the Trans-Pacific Partnership). It is possible to succeed with numerous weaknesses it just requires even more offsetting benefits to attract technology entrepreneurs.

Some things are probably absolutely required: rule of law, strong technology infrastructure (internet, etc.), good transportation links internationally, stable politically, freedom of expression (technology entrepreneurs expect to be able to try and say crazy things if you want to control what people say and publish that is very counter to the technology entrepreneurial spirit – especially around internet technology)…

Roominate: Inspiring Artists, Engineers and Visionaries

Posted on August 20, 2012  Comments (3)

Roominate is a cool new toy created by 3 engineering students aimed at giving young engineers a way to learn, experiment and create. The 3 women used kickstarter to get the funds needed to launch their product. They raised $85,000 (the goal was $25,000).

We’re more than just a toy company. We want to inspire your daughters to be the great artists, engineers, architects, and visionaries of their generation. We intend to give them every tool to reach that potential.

Founders:

Bettina Chen: CalTech BS in Electrical Engineering, masters in Electrical Engineering from Stanford.

Alice Brooks: MIT BS in Mechanical Engineering, currently at Stanford pursuing masters in Mechanical Engineering design.

Jennifer Kessler: Bachelor degree from University of Pennsylvania, currently an MBA student at Stanford.

This is yet another example of entrepreneurship shown by Standford students. The USA is hugely benefited by Stanford (along with a few other schools: MIT, Caltech, etc.). There is little a country can do that is as helpful economically as encouraging the type of entrepreneurship Standford does.

Engineers Again Shown to Lead More Companies Than Other Disciplines

Posted on February 6, 2012  Comments (1)

I have written previously about the fact that more S&P 500 CEO’s are engineering majors than any other discipline. The group putting out those studies have stopped doing so, unfortunately. There is a new study based on mining Facebook data and the results again show engineers doing very well.

I wish they provided data for the larger companies, but they don’t. They show a breakdown of 9,461 (CEO or founders) with a business undergraduate major and 9,334 with an engineering degree. For those with advanced degrees 3,337 have an engineering master’s or doctorate and 1,016 have an MBA.

In the latest (2008) data I have for S&P 500 CEO’s 22% were engineers. Engineers seem to make up under 5% of college graduates (based on my eyeballing of this Dept. of Education data). Business meanwhile seems to make up about 20% of the majors.

Companies Sharing Engineering Resources Across the Globe

Posted on December 2, 2011  Comments (1)

Swapping batteries for diesel engines

Car companies, like aircraft manufacturers, are sharing engineering skills across borders to speed up and cut the costs of technological development. It happened with Boeing’s 787 Dreamliner. The American aircraft maker outsourced some of the engineering to Japanese suppliers, admitting that it does not have all the necessary expertise. Likewise, Toyota has agreed to work on hybrid trucks with Ford, and electric vehicles with Tesla, the Silicon Valley sports-car maker. BMW is working on improving the current generation of lithium-ion batteries with France’s Peugeot Citroën. Nissan, as well as joining forces with Renault, has joint projects with Daimler.

There are many reasons to pursue such efforts (as well as drawbacks). My belief is companies would rather not take on the complications of such partnerships but the advantages overcome those desires. The high cost of research into these efforts is a big part of what pushes such collaboration. Also once a company has success they often can build up quite an advantage. The costs of trying to engineer a different solution (that doesn’t violate someone’s patents) often makes buying that technology or partnering attractive.

I really like this webcast, from 2008, on Toyota’s engineering development program.

Cutting the Boarding Time of Planes in Half

Posted on August 31, 2011  Comments (4)

I thought I wrote about this several years ago, but I guess I didn’t (I can’t find it, if I did). Experimental test of airplane boarding methods:

The Ste en method, on the other hand, orders the passengers in such a way that adjacent passengers in line are sitting in corresponding seats two rows apart from each other (e.g., 12A, 10A, 8A, 6A, etc.). This method trades a small number of aisle interferences at the front of the cabin, for the benefit of having multiple passengers stowing their luggage simultaneously. Other methods, such as Wilma and the Reverse Pyramid also realize parallel use of the aisle in a natural way as adjacent passengers are frequently sitting in widely separated rows.
…
We have seen experimentally that there is a marked difference in the time required to board an aircraft depending upon the boarding method used. The evidence strongly supports the heuristic argument from Ste en that methods that parallelize the boarding process by more efficiently utilizing the aisle (having more passengers stow their luggage simultaneously) will board more quickly than those that do not. The relative benefit of the application of this theory will grow with the length of the aircraft. Here, we used a 12-row mock airplane, but a more typical airplane with twice that number of rows will gain more by the implementation of parallelized boarding methods.

How this improvement scales with the cabin length is different for each method. For the Ste en method, the benefit will scale almost linearly. If the airplane is twice as long, the time savings will be nearly twice as much since the density of luggage-stowing passengers will remain the same and the boarding will still be maximally parallel. For Wilma and random boarding the benefit will not be as strong since the benefits of parallel boarding are randomly distributed along the length of the cabin instead of being regularly distributed.

I am not optimistic that airlines will even test out this method. People tend to think companies apply sensible, proven concepts and methods. But that is much less likely to be done than people think. The failure of many places to use simple queuing theory improvement (customers should form one line and be served the next available person not form many individual lines) is one example of failures by companies to apply decades old proven better methods. The poor adoption of multivariate designed experiments is another. Applying better ideas is a process that is not done very efficiently in business, health care, education or even science and engineering – in fact in any human endeavor. This is a waste that impacts each of us every day. It is also an opportunity for you to gain advantages just by applying all the good ideas lying around that others are ignoring. You need to test the ideas out in your setting (using the PDSA cycle in an organizational context a good method).

S&P 500 CEO’s: Engineers Stay at the Top

Posted on August 20, 2009  Comments (12)

2008 Data from Spencer Stuart on S&P 500 CEO (link broken so it was removed, it is so sad that companies still pay people to manage web sites that don’t even understand basic web usability principles such as web pages must live forever) shows once again more have undergraduate degrees in engineering than any other field, increasing to 22% of CEO’s this year.

Field
% of CEOs
2008
2007
2006
2005

Engineering 22 21 23 20
Economics 16 15 13 11
Business Administration 13 13 12 15
Accounting 9 8 8 7
Liberal Arts 6 6 8 9
No degree or no data 3 3

In 1990 Engineering majors accounted for 6% of the bachelor’s degrees in the USA (1970 5%, 1980 7%). Business accounted for 23% of the majors in 1990 (1970 14%, 1980 21%). Liberal arts 3% in 1980 (1970 1%, 1980 2%).

The report does not show the fields for the rest of the CEO’s. 39% of S&P CEOs have MBAs. 28% have other advanced degrees. The University of Wisconsin-Madison and Harvard tied for the most CEO’s with undergraduate degrees from their universities at 13. Princeton and the University of Texas had 9 and Stanford had 8.

While the CEO’s have engineering education backgrounds the work they have done is often in other functions. The top function that CEO’s that have worked in during their careers: Operations (42%), Finance (31%), Marketing (24%), Sales (17%), Engineering (11%).

How to Develop Products like Toyota

How to Develop Products like Toyota

Sobek also says Toyota tends to stay as flexible as possible until relatively late in the development stage. He cites as an example Toyota’s practice of leaving manufacturing tolerances to be set by die makers rather than by design engineers creating the prints. Die makers make die dimensions as close as practical to those in the CAD database, but have the flexibility to modify them so body parts fit together well. Manufacturing engineers then set tolerances around manufacturing capabilities.
…
“Test first, then design. First run simulations and understand where the boundaries of solutions lie. Once you understand the alternate spaces between competing choices, you narrow the options in what are called integrating events.”

Integrating events are an opportunity to eliminate weak opportunities. It is only after these events are complete that detailed design commences. “The point is that you don’t get to detailed design until everything works,” says Kennedy. “That is the reason Toyota focuses so intently up front on understanding trade-offs.”

This is very similar to agile software development practices. Though due to different processes, software versus car manufacture the two process are not identical.

Though Toyota is adept at developing products, it may be a mistake to adopt its practices wholesale, no matter how good they are. “Much of the lean community tries to crow-bar Toyota’s approach into their own very different business model,”

This is always true. Copying what others do does not work. You can learn from others by understanding the benefits of their process and then adapting the ideas to your organization.

Toyota has several tools that help its engineers organize the tasks at hand. One of the most well known is called the A3 document, named for the size of the paper its information is written on. An A3 holds a distillation of project goals and customer wants. During development, it can serve as a crib sheet for engineers as they set priorities and make trade-offs. “A3s enforce the plan-do-check- act methods of quality,” explains Kennedy. “The A3 becomes the basis for Toyota’s entire review process.”

On my management improvement blog I discuss the Toyota Production System often, you can follow those posts if you are interested.
