Jim McKelvey on Discovering — and Defending — Innovations (HBR IdeaCast 730)

Discover the latest Podcast from HBR. Curt Nickisch,senior editor at Harvard Business Review, interviews Square's co-founder Jim McKelvey on discovering and defending innovations. HBR IdeaCast 730 (March 17, 2020)

"Jim McKelvey says that most companies that think of themselves as innovative are really just copycats. True innovation, he argues, is about fearlessly exploring novel solutions and dramatically expanding markets. Doing so also helps startups defend their innovations against industry giants, as Square did against Amazon." 

McKelvey is the author of the book “The Innovation Stack: Building an Unbeatable Business One Crazy Idea at a Time.”

Biochar: a tool to combat climate change and to increase water retention of the soil ?

Biochar is a Powerfully Simple Tool to Combat Climate Change
What is Biochar?
"Biochar is a solid product obtained in the pyrolysis of biomass. It is a carbon-rich and porous material that can be used for a wide range of applications, among which soil improvement, remediation, and pollution control take the most important roles.
As a product, biochar differs from charcoal, which is produced at lower temperatures and considered as solid fuel, containing a high quantity of volatile matter. Because of higher process temperatures, the chemical structure of biomass changes and content of hydrogen, nitrogen, and oxygen in biochar is significantly decreased in relation to carbon. In contrary to charcoal, biochar is also not phytotoxic.
Biochar is mainly used in agriculture to enhance soil fertility, improve plant growth, and provide crop nutrition. As a result, it improves the overall farming productivity. It has also gained considerable attention in livestock farming as an animal feed."

A simple Tool to Combat Climate Change
The carbon in biochar resists degradation and can hold carbon in soils for hundreds to thousands of years. Biochar is produced through pyrolysis or gasification — processes that heat biomass in the absence (or under reduction) of oxygen.

In addition to creating a soil enhancer, sustainable biochar practices can produce oil and gas byproducts that can be used as fuel, providing clean, renewable energy. When the biochar is buried in the ground as a soil enhancer, the system can become “carbon negative.”

Biochar and bioenergy co-production can help combat global climate change by displacing fossil fuel use and by sequestering carbon in stable soil carbon pools. It may also reduce emissions of nitrous oxide.

We can use this simple, yet powerful, technology to reduce carbon emissions.

In France, Hydrochar WB1 is Biochar homologated by the ANSES for water retention.

Smart irrigation model predicts rainfall to conserve water

From the Cornell Chronicle (By Melanie Lefkowitz, July 16, 2019)

More than 70% of fresh water is used for agriculture. However, irrigation technologies are not often smart and water is often overconsumed. Chao Shang, Wei-Han Chen, Abraham Duncan Stroock, and Fengqi You have developed a robust predictive model of irrigation that could save 40% of the water consumed.


Previously, Stroock’s group developed sensors to determine when plants are thirsty. But sensors alone are insufficient because growers don’t need to irrigate if rain is on the way. Considering the weather prediction is better but not ideal, Chao said, because forecasts are often wrong, and the uncertainty of a forecast may be greater than the expected rainfall.

The researchers’ method uses historical weather data and machine learning to assess the uncertainty of the real-time weather forecast, as well as the uncertainty of how much water will be lost to the atmosphere from leaves and soil. This is combined with a physical model describing variations in the soil moisture.


Integrating these approaches, they found, makes watering decisions much more precise.

Inside Tesla Factory - TESLISM

In a recent HBR article How Tesla Sets Itself Apart,  Lou Shipley tells us 

By mid-January, Tesla’s market capitalization had reached $107 billion, and it surged past the giant German automaker Volkswagen to become the world’s second most valuable auto company behind Toyota.

What is the secret behind Tesla's success?

Lou Shipley's article provides us with interesting cues. However, former McKinsey&Co consultant, Michaël Valentin offers us a new look at Tesla in a book. Michaël Valentin contends that Tesla has invented a new productive system, like Toyota created one a few decades ago. He calls it TESLISM. For example, Tesla development and production model is highly integrated. Functions are highly integrated. Teams are co-localized on the factory floor and together they solve problems using a scrum approach.   


The book is also available in French.
