Importance of natural mechanism

For creating a new vision of our future under energy-environmental problems

and constructing the intelligent infrastructure

Importance of Natural Mechanism

13 October 2006

Workshop in RE2006

Haruki SATO, Professor, Keio University, Japan


What should we do for creating new three stages of research

What should we do for creating new?Three stages of research

  • Future technology (Dream?): ENERGY UTILIZATION

    • Simulation of future vision is important to concentrate R&D.

      • Who should study on this? government? We should make it.

    • Problem: It will not be supported by manufacturers.

    • Creating originality of your country is important.

      • Answer should not be only one (diversity).

  • Advanced technology (Current technology): many researches

    • great financial support will be provided from manufacturers, government, and other countries.

  • Infrastructure for technology: FLUID PROPERTY

    • Database and software like material properties

    • Problem: It spends money but does not directly make money.

    • Leveling-up your country in future. (Prof. Tanishita did this.)

For creating a new vision of our future under energy-environmental problemsand constructing the intellectual infrastructure


Infrastructure for technology why fluid property

Infrastructure for technology Why Fluid Property?

  • Late Prof. Ichimatsu Tanishita

    • 1907- February 2005

    • He wrote a text book ‘Thermodynamics’

    • My Laboratory

      • Tanishita – Watanabe - Sato

    • 60 years ago, nothing in Japan

    • What did he do?

      • started to study on properties of steam

For creating a new vision of our future under energy-environmental problemsand constructing the intellectual infrastructure


Why did he study on steam properties why japan became one of leading countries

Why did he study on steam properties?Why Japan became one of leading countries?

  • He thought that Japan must construct power generation plant by own technology.

    • Then what did he do?

  • He attended at International committee for preparing Steam Tables as an observer.

  • When the present IAPWS was established in 1970, Japan was a member country.

  • Now, Combined Cycle of power generation system has the efficiency higher than 50%.

Learn from trees as the natural mechanism

  • Why are leaves not high temperature like surface of metal under strong sunshine?

  • Is it cooler under a tree?

  • How do leaves get waterfrom root?

  • What is transpiration?

Water is important

Water is important?

  • Under a tree, there is a large water jar.

  • How trees bring water to each leaves?

For creating a new vision of our future under energy-environmental problemsand constructing the intellectual infrastructure


Is it cooler under a tree why

Is it cooler under a tree? Why?

  • Water evaporates from each leaves.

  • When water changes tosteam, it need heat.

  • Leaves and air around the leaves are cooled.

  • Cooler air goes down by natural convection.

Summary of natural artificial space

Summary of Natural Artificial Space

  • It is only one example for alternative smart air-conditioning.

    • 1.Air-conditioning makes outside hotter (heat island in Japan).

    • 2.Small energy consumption is good enough for air-conditioning.

    • 3.We should learn from tree.

    • Not only mechanical engineering, but also many other

    • fields such as architecture, bio-engineering, health care

    • should be collaborated to create new space conditioning.

    • = system design engineering

Do you know

Do you know?

When ambient temperature is higher, we will be wet.

The control mechanism of pores for sweat in the skin

by autonomic nerve is determined by incentive of

two or three years old.

If he or she grew completely within air-conditioned

circumstance. ・・・What will happen for them?

・・・It is an example that artificial circumstance affect

our body.

Summary of my talk today

  • I talked only background of my study today.

    • Create a new Infrastructure for symbiotic community by learning the natural mechanism like trees and the leaves.
