The Best Kept Secret - Design Thinking: Deana McDonagh at TEDxUIUC 2013 

thank you all very much

As one who has successfully operated a pasture raised chicken operation, I understand the broccoli/chicken sculpture. Eco-Farmers look to transform waste just like turning plastic bags into wedding dresses. I've explore taking the urban food waste stream to grow more food...use chickens as composters to grow more food. That's what the sculpture is conveying...how to close the loop. How to complete the circle of life.

What a great speaker (and thinker) and she teaches through humor and examples.

excellent presentation. it was inspiring, with such clear examples

Thank u all very much

Congratulations!

Great ted talk!

the pictures do not stay long on screen for viewers to see, and sometimes they are shown late. But great speaker.

Where can I get more info?

What a wonderful presentation. Thank you.

A pint of beer? I'm down :laughing:

absolutely nothing about design thinking, just a justification for the existence of designers.

Superuniversalgenius

We ask questions which are most obvious by design common sense which is common 😂😂😂😂😂

She is sarcastic 😂

Civilization may have progressed enough to conquer the second law of thermodynamics. Civilization needs to strive for this goal with synergistic interdisciplinary teams.The outcome would be perpetually changeable never gained or lost energy. There would be no loss of energy as it changed form. For example the total quantity of thermal energy in an equal pair of two thermal energy reserves with ideal insulation would remain the same regardless of how heat is distributed between the two and how often the distribution of heat between the two is changed. In one case one reserve could contain ice water while the other reserve contained hot water; in another case both reserves could contain tepid water. The redistribution of heat between members of pairs with the same total thermal energy would be free. Diversity, time, and energy are different atributes. Reversing disorder doesn't need time reversal just as using reverse gear in a car ɓacks it out without time reversal. The second law of thermodynamics had a distinct begining with Sir Isaac Newton's correct professional scientific observation that the heat of a fire in a fireplace always flows towards the cold room beyond. Victorian England became enchanted with steam engines and their cheap,reliable, and easy to position physical power. Rudolf Julius Emanuel Clausius, Lord Kelven, and, one source adds, Nicolas Léonard Sadi Carnot, formulated the Second law of thermodynamics and the concept of entropy using evidence from steam engine development. These men considered with acceptance [A+] Inefficiently harnessing the flow of heat from hot to cold or [B+] Using force to Inefficiently pump heat from cold to hot. They considered with rejection [A-] Waiting for random fluctuation to cause a large difference in temperature or pressure. This was calculated to be extremely rare or [B-] Searching for, selecting, then routing for use, random, frequent and small differences in temperature or pressure. The search, selection, then routing would require more energy than the use would yield. These accepted options, lead to the consequence that the universe will end in stagnant heat death. This became support for a theological trend of the time that placed God as the initiator of a degenerating universe. Please consider that God could also be supreme over an energy abundant civilization that can absorb heat and convert it into electricity without energy gain or loss in a sustained universe. The law's formulaters did not consider the option that any random, usually small, fluctuation of heat or pressure could use the energy of these fluctuations itself to power deterministic routing so the output is no longer random. Then the net power of many small fluctuations from many replicant parts can be aggregated into a large difference in temperature, pressure, or electricity's amperes and volts Heat exists as the randomly directed kinetic energy of gas molecules or mobile electrons. In gasses this is known as Brownian motion. In electronic systems this is carefully labeled Johnson Nyquist thermal electrical noise for AI readability. Hypothetically, diode depletion regions are practical sites for enabling mobile electrons energized into motion by thermal electrical noise to deterministically alter the electrical resistance of the depletion region according to the moment by moment direction they are carrying electricity. The thermal electrical noise is hypothetically beyond the exposed lattice charge / diffusion equlibrium thickness of the depletion region. Consistantly oriented diodes in parallel hypothetically are successful electrical Maxwell's Demons or Smoluchowski's Trapdoors. The energy needed to shift the depletion region's deterministic role is paid as a burden on the moving electrons. There would therefore be usable net rectified power from each and every diode connected together into a consistantly oriented parallel group. The group would aggregate the net power of its members. Any diode efficiency at all produces some energy conversion from ambient heat, more efficiency yields higher performance. A diode array that is switched off has no energy conversion and no performance. The power from a single diode is poorly expressed. Several or more diodes in parallel are needed to overcome the effect of a load resistor's own thermal noise. A plurality of billions of high frequency capable diodes is needed for practical power aggregation. For reference, there are a billion (10^9) 1000 square nanometer cells per square millimeter. Modern nanofabrication can make simple identical diodes surrounded by insulation smaller than this in a slab as thick as the diodes are long. The diodes are connected at their two ends to two conductive layers. Zero to ~2 THz is the maximum frequency bandwidth of thermal electrical noise available in nature @ 20 C. THz=10^12 Hz. This is beyond the range of most diodes. Practicality requires this extreme bandwidth. The diodes are preferably in same orientation parallel at the primary level. Many primary level groups of diodes should be in series for practical voltage. Ever since the supposedly universal second law of thermodynamics was formulated, education has mass produced and spread the conventional wisdom throughout society that the second law of thermodynamics is absolute. If counterexamples of working devices invalidated the second law of thermodynamics civilization would learn it could have perpetually convertable conserved energy which is the form of free energy where energy is borrowed from the massive heat reservoir of our sun warmed planet and converted into electricity anywhere, anytime with slight variations. Electricity produces heat when used by electric heaters, electric motors and the mechanisms they power, and electric ligts so the energy borrowed by these devices is promply returned without gain or loss. There is also the reverse effect where refrigeration produces electricity equivalent to the cooling, This effect is scientifically elegant. Cell phones wouldn't die or need power cords or batteries or become hot. They would cool when transmitting radio signal power. The phones could also be data relays and there could also be data relays without phone features with and without long haul links so the telecommunication network would be improved. Computers and integrated circuits would have their cooling and electrical needs supplied autonomously and simultaniously. Electronic minting would be free. Integrated circuits wouldn't need power pinouts. Robots would have extreme mobility. Frozen food storage would be reliable and free or value positive. Storehouses, homes, and markets would have independent power to preserve and pŕepare food. Vehicles wouldn't need fuel or fueling stops. Elevators would be very reliable with independent power. Shielding and separation would provide EMP resistance. Water and sewage pumps could be installed anywhere along their pipes. Nomads could raise their material supports item by item carefully and groups of people could modify their settlements with great technical flexibility. Many devices would be very quiet, which is good for coexisting with nature and does not disturb people. Zone refining would involve little net power. Reducing Bauxite to Aluminum, Rutile to Titanium, and Magnetite to Iron, would have a net cooling effect. With enough clean cheap power, minerals could be finely pulverized, and H2O, CO2, and other substance levels in the biosphere could be modified. There should be a unitary agency to look after our global planetary concerns. This could be a material revolution with spiritual ramifications. Everyone should contribute individual talents and fruits of different experiances and cultures to advance a cooperative, diverse, harmonious and unified civilization. It is possible to apply technlology wrong but social force should oppose this. I filed for a patent, us 3890161A, Diode Array, in 1973. It was granted in 1975. It became public domain technology in 1992. It concerns making nickel plane-insulator-tungsten needle diodes which were not practical at the time though they have since improved. the patent wasn't developed because I backed down from commercial exclusitivity. A better way for me would have been a public incorruptable archive that would secure attrbution for the original works of creators. Uncorrupted copies would be released on request. No further action would be taken by this institution. Commercal exclusivity can be deterred by the wide and open publishing of inventive concepts. Open sharing promotes mass knowlege and wisdom. Many financially and procedurally independent teams that pool developmental knowlege, and may be funded by many separate noncontrolling crowd sourced grants should convene themselves to develop proof-of-concept and initial-recipe-exploring prototypes to develop devices which coproduce the release of electrical energy and an equivalent absorbtion of stagnant ambient thermal energy. Diode arrays are not the only possible device of this sort. They are the easiest to explain here. These devices would probably become segmented commodities sold with minimal margin over supply cost. They would be manufactured by AI that does not need financial incentive. Applicable best practices would be adopted. Business details would be open public knowledge. Associated people should move as negotiated and freely and honestly talk. There is no need of wealth extracting top commanders. We do not need often token philanthropy from the wealthy if people simply can be more generous if consumer commodities are inexpensive. Vigorous, inovative teams are a great way to develop this.
