With more cars becoming hybrid electric and total electric powered, the demand for Electrical and Computer engineers will increase in the auto

industry.

The Volt by GM will be an all electric car. Other manufacturers are also introducing all electric cars

This was a good idea but was scrapped because the solar

powered lights would not provide

enough illumination. It will be revisited as solar cells and

LEDS become more efficient and

brighter

Opto-electronics (devices that use light) include LEDs or light emitting diodes, solar cells, and fiber optic components

10 Stages of Design Process

1. Identify the problem/product innovation 2. Define the working criteria/goals 3. Research and gather data 4. Brainstorm/generate creative ideas 5. Analyze potential solutions 6. Develop models/prototypes 7. Make a decision 8. Communicate and specify 9. Fabricate and commercialize 10. Perform post-implementation review and assessment

How much does it cost to run a 100 watt light bulb

Typical cost from Duke Power is $.08/Kw-Hr Convert 100w to Kw (Kw = 103W) 100W=.1 KW For 1 hour a 100w light bulb uses .1 KW-Hr For 24 hours, a 100W light bulb uses (24 hr) x

(.1 KW-hr) = 2.4 Kw-Hr/day Cost for 24 hr is ($.08/Kw-hr) x (2.4 Kw-hr/day)

=$.192/day Cost for a month is (30 days) x ($.192/day) =

$5.76/month Cost for a year is (365 days) x ($.192/day) =

$70.08/year

Compare cost to a high efficiency replacement lamp

If an equivalent high efficiency lamp uses 13 watts instead of 100 watts

13 watts = .013 Kw (.013 KW-Hr) x (24Hr/day) = .312 KW-Hr/day ( $.08/Kw-Hr) x (.312 KW-Hr/day) = $.02496/day ($.02496/day) x (365 days/yr) = $9.11/yr

100watt light bulb = $70.08/yr 13 watt light bulb = $9.11/yr Based on lamp running 24 hours per day,

everyday for a year

This analysis can be used for any electrical device

Every electrical device will show power required to operate it

Typical computer may use 120V, 1.5A (120V)(1.5) = 180 watts = .180 Kw (.180 Kw-hr) x ($.08/Kw-Hr) = $.0144/Hr ($.0144/hr) x (24 hr/day) = $.3456/day ($.3456/day) x (365 days/yr) =

$126.144/yrThere will be a questions on this
