Colorado – The road to carbon neutrality

Well written article in the Colorado Sun on the state of Colorado’s energy infrastructure and the quest for renewable energy.

Wind turbines near Matheson, Colorado, are part of Xcel Energy’s new 600 megawatt Rush Creek Wind Project. Rush Creek, which became operational in October 2018, uses 300 turbines to generate enough electricity to power 325,000 homes. Xcel estimates the project will cut 1 million tons of carbon emissions each year from its system. (John Leyba, Special to The Colorado Sun)

Spinoza and William James on Freedom

From the essay, The Will, by William James:

Spinoza long ago wrote in his ethics that anything that a man can avoid under the notion that it is bad he may also avoid under the notion that something else is good. He who habitually acts sub specie mali, under the negative notion, the notion of the bad, is called a slave by Spinoza. To him who acts habitually under the notion of good he gives the name of freeman. See to it now, I beg you, that you make freemen of your pupils by habituating them to act, whenever possible, under the notion of a good. Get them habitually to tell the truth, not so much through showing them the wickedness of lying as by arousing their enthusiasm for honor and veracity.

From The Ethics, Benedictus de Spinoza:

PROP. LXVII. A free man thinks of death least of all things; and his wisdom is a meditation not of death but of life.

Proof.–A free man is one who lives under the guidance of reason, who is not led by fear (IV. lxiii.), but who directly desires that which is good (IV. lxiii. Coroll.), in other words (IV. xxiv.), who strives to act, to live, and to preserve his being on the basis of seeking his own true advantage; wherefore such an one thinks of nothing less than of death, but his wisdom is a meditation of life. Q.E.D.

Toyota’s Six Rules for the application of kanban

Toyota has formulated six rules for the application of kanban

  1. Each process issues requests (kanban) to its suppliers as it consumes its supplies.
  2. Each process produces according to the quantity and sequence of incoming requests.
  3. No items are made or transported without a request.
  4. The request associated with an item is always attached to it.
  5. Processes must not send out defective items, to ensure that finished products will be defect-free.
  6. Limiting the number of pending requests makes the process more sensitive and reveals inefficiencies.
