Preliminary Ideas

Team LED Zeppelin

Design can be used year round

Design is not location dependent

System is highly durable and produces decent energy output

Selection Criteria

Wind is a renewable clean energy source. Our team brainstormed

on how to harness and maximize wind power in an urban setting.

Vertical axis system with a

carbon filament enforced plastic

material

Generator is located close to the turbine and

the wiring is encased by

metallic tether

Generator is suspended by a

large helium latex balloon

Built-in anemometer, to retract it when

wind speeds are high enough to

damage the system

What makes up

the system?

The PartsThe Turbine

Cap Cover

Generator Generator CapPower (W) =

(1/2) * Cp * A * v3

Wind Speed (m/s) = v10 *

(h/10)a

Size of Turbine Blade (m3) = r * (r * 2) * (r * Tr)

Balloon Flight Time (days) = ((BL – BW – WS)/LL)/24

Balloon (g) = V * 1. Lift 01

Fundamental Principles

Unstable winds speeds, lightening, and a six day flight time possibly constrain the system,

but under ideal conditions the following energy outputs are obtained:
