2 Objectives At the end of this exercise, you will be able to:

3 Successfully create a new timed event. Successfully configure a new timed event. Successfully update the PC interface. Successfully configure a sequence of timed events.

4 About This Presentation First, let’s take a quick look at some timers. Then, let’s look at a high-tech way of generating electricity to be part of our automated home.

5 Timers Mechanical Electronic Computer software

6 Mechanical Timers Cheap Work simply Require human intervention to maintain

7 Electronic Timers Accurate Multifunction Reliable Easy to use

8 Computer Software Timer Accurate Versatile But only when the computer is on

9 Fuel Cells – So, What Is A Fuel Cell?

10 What Else Do They Produce? Water Heat

11 Are They Big or Small? Courtesy Lawrence Livermore National Laboratory

12 But this is larger. Courtesy UTC Fuel Cells

13 Are They New? Yes, and no.

17 What is inside a fuel cell?

18 But how does a fuel cell work?

19 The alkali fuel cell

20 The molten carbonate fuel cell

21 The phosphoric acid fuel cell (PAFC)

22 The solid oxide fuel cell (SOFC)

23 What Is A Regenerative Mode? Running a fuel cell backwards Input electricity and water Fuel cell will produce hydrogen and oxygen.

24 Here is an example H-TEC Photo

25 How Else Can We Get Hydrogen? Hydrogen generators Courtesy 2001 National Air and Space Museum, Smithsonian Institution (SI Neg. No )

26 Once You Have Hydrogen, Where Do You Store It? Steel cylinders Containers of super-activated carbon.

27 Fuel Cell Benefits Clean, quiet, and highly efficient Reduced fuel consumption Produces heat and power Fuel flexible No combustion

28 And More Benefits Modular and scalable Significantly reduces air pollution Are part of system to reduce blackouts, brownouts, and voltage sags
