WHY?

 You may be asking yourself WHY?
      - why draw parallels between the Boltzmann equation
        and business
      - why should I care about such non-scientific subject
        this is RPI not some lame business school

When Opportunity meets Preparation--- great things happens!

Side Note


                Ronco stuff was selling like crazy
                since the ’60’s.

                In the early ’80s they could not
                sell their “CleanAire Machines”,
                competitors entered a price war and
                Ronco went bankrupt.
     How do you predict competition so strong that
     it drives you to bankruptcy?
Seriously, if you “invented” an inside-the-egg-mixer,
how would you sell it?

The Business Plan

The Basic Balance equation
  n(r,t)d3r = expected number of particles in d3r about r at time t.

  ψ(r,t) = vn(r,t) = the angular flux of particles where v is the velocity


        s(r,t)d3r = the source term
   CV


    vΣa(r)n(r,t) d3r = the absorption term
  CV


    vΩ       n(r,t) dΩd3r = the net leakage term
4π CV

   Requiring that the surface be non-reentrant and rewriting
   as rate of change = gains – losses
                                      Transitioning Quantum Dot Technology into Commercially Viable Products   17
Since we want this to be related to a company that produces their own
cash flow instead of relying on a fixed “source”, we add an additional Source
term as a fission source, so



dn(r,t) sfixed(r,t)d3r + vνΣf(r)n(r,t) d3r         vΣa(r)n(r,t) d3r                    vΩ         n(r,t) dΩd3r
 dt =                                          CV                             4π CV
        CV             CV




  Gain from        Gain from                Loss due                          Loss due
  Fixed source     Fission source           to absorption                     to leakage



             Difficult to solve, right?

Now assume
   n(r,t)d3r = expected cash in d3r about r at time t.

  In reality, you can only solve the Boltzmann equation for
  idealized situations OR make assumptions and approximate.

In business, the solution is presented as your “business plan” and
it is also filled with assumptions in order to approximate things
  Typical Assumptions:
        - fixed source of cash to start up
        - estimated expenses
        - estimated time required to sell first product
        - assumed “control volume” determining target market

Notes

You can be super-critical (sources>>losses) as a one-person
company generating only royalty-based revenue.

You can be a massive company that is subcritical even with
brisk sales and high margins (good profit on each sale).

You can be just critical – not for profit

You need to define the mission of the company, what type
of company are you going to be?


    Typically the Board of Directors makes this decision.

temperature differences to electric voltage and vice-versa.


  Current thermoelectric materials SUCK!

  They have sucked for decades although
  they have been heavily studied.

     change the world with our technology!!!!

            Then we tell our grandchildren how we took
            an idea and made great things happen.



                  Then we die and are buried but when we
                  turn to fossil fuel nobody will dig us out of
                  the ground because one of you in the room
                  will invent something that will eliminate
                  the need to fossil fuels,.
                                            - FIN



                                      Transitioning Quantum Dot Technology into Commercially Viable Products   71
If a man hasn't discovered something
he will die for, he isn't fit to live.
                                         - Martin Luther King

Boltzmann Technologies Presentation

  • 1. Drawing parallels between the Boltzmann Transport Equation and the random walk of a high tech company 4 April 2012 Presented by Clint Ballinger
  • 2. GEEK G Crude Attempts at Humor Randomness Mild Scientific Language Rating by the Society of Nanotechnologists Transitioning Quantum Dot Technology into Commercially Viable Products 2
  • 3. Agenda Introduction - Who am I and why am I here Technical Stuff -Evident’s basic technology -Boltzmann Transport Equation (BTE) and how it relates to B$E Non-Technical Stuff -Real life examples and how they relate to the terms of the B$E Hidden Agenda: If you can understand and solve complex equations, you can commercialize an idea! Transitioning Quantum Dot Technology into Commercially Viable Products 3
  • 4. Who? Developed Monte Carlo methods for electron, photon and neutron transport calculations. Classically trained in Nuclear Engineering Creativity/Education + Retarded Optimism = Entrepreneur Some skills that Failure is not an option differentiate you from society World average years of education = 6.1 Transitioning Quantum Dot Technology into Commercially Viable Products 4
  • 5. Transitioning Quantum Dot Technology into Commercially Viable Products 5
  • 6. WHY? You may be asking yourself WHY? - why draw parallels between the Boltzmann equation and business - why should I care about such non-scientific subject this is RPI not some lame business school When Opportunity meets Preparation--- great things happens! Who in the World is better positioned to create the next technology breakthrough? Transitioning Quantum Dot Technology into Commercially Viable Products 6
  • 7. TV Remote control Microwave oven LEDs Smoke detectors GPS I want YOU To develop a cure for cancer, create transportation that does not rely on fossil fuel, store electricity efficiently and cheaply, and make a space elevator!!! Transitioning Quantum Dot Technology into Commercially Viable Products 7
  • 8. Semiconductors Electrons are mobile Electrons are in the “conduction band” e- Conductor -metal Electrons are not very mobile Electrons are in the “valance band” e- Insulator -glass Transitioning Quantum Dot Technology into Commercially Viable Products 8
  • 9. Semiconductors e- V e- Semiconductor e- e- Semiconductor No stimulus Transitioning Quantum Dot Technology into Commercially Viable Products 9
  • 10. Semiconductor Bulk “natural” material Nanomaterials Atoms/Molecules Transitioning Quantum Dot Technology into Commercially Viable Products 10
  • 11. Our Technology We make semiconductor nanocrystal a.k.a. quantum dots Avg Size = 55 ± 6 Å 20 nm PbS Core Initial Idea- use this material as a nonlinear optical element in telecom switching applications Transitioning Quantum Dot Technology into Commercially Viable Products 11
  • 12. Our Technology e- Bohr Radius for the Material Transitioning Quantum Dot Technology into Commercially Viable Products 12
  • 13. Wavelength Dependent on Size and Material System e- e- What can you do with a tunable bandgap semiconductor that is nano-sized? Transitioning Quantum Dot Technology into Commercially Viable Products 13
  • 14. Our Technology Transitioning Quantum Dot Technology into Commercially Viable Products 14
  • 15. Platform technology Nano-sized semiconductor crystals have hundreds of applications. How do you turn it into a business? What is a business plan? Why fight the laws of physics when you can just do something simple and make crazy money! Transitioning Quantum Dot Technology into Commercially Viable Products 15
  • 16. Side Note Ronco stuff was selling like crazy since the ’60’s. In the early ’80s they could not sell their “CleanAire Machines”, competitors entered a price war and Ronco went bankrupt. How do you predict competition so strong that it drives you to bankruptcy? Seriously, if you “invented” an inside-the-egg-mixer, how would you sell it?

  • 25. Notes You can be super-critical (sources>>losses) as a one-person company generating only royalty-based revenue. You can be a massive company that is subcritical even with brisk sales and high margins (good profit on each sale). You can be just critical – not for profit You need to define the mission of the company, what type of company are you going to be? Typically the Board of Directors makes this decision.
