Harder problems make for better inventions.

a.k.a.

Constraints are good.

Hypothesis: The big cleantech industries of the 21st century will be born in the developing world.

A couple examples: #1: Solar water disinfection

Two million people use Solar Water Disinfection regularly for their clean

water.

A couple examples: #1: Solar water disinfection

Why only two million?

Solar water disinfection : The redesign constraints

1. Can be manufactured in Haiti 2. Will last for two months 3. Completely transparent structure 4. Less than US$0.50 selling price 5. Easy to fill 6. Easy to pour 7. Someone will trust it and buy it

Solar water disinfection : The new product: A better bag

A couple examples: #2: A new type of wind power

Wind power today…

A new type of wind power: The redesign constraints

1.  Can be manufactured in emerging and wealthy countries alike

2.  $2 for a wind generator that can light an array of LEDs, equivalent to a kerosene lamp

3.  Easy to maintain 4.  Minimize grinding, wearable parts

Invent the simplest & least expensive wind generator in the world. of all time. ever.

A new type of wind power: These constraints mean we needed to…

A new type of wind power: The three ingredients to a new idea

A new type of wind power: The Windbelt technology

Several years ago: Initial demo of the basic WindbeltTM

technology.

A new type of wind power: The Windbelt technology

WindbeltTM

transformed into the Windcell, Windcell PanelTM

, and the µicroBeltTM

The Windbelt technology: Evolution into the Windcell Panel

The Windbelt technology: Evolution into the Windcell Panel

A single Windcell Panel is 1 meter x 1 meter square. 100 W. $1 per watt.

Energy Cost Comparison

Remote diesel USD$0.20 - $0.70 / kWh

Solar PV (2kW-scale)‡ USD$0.30 - $0.50 / kWh

Wind turbines (2 kW-scale)‡ USD$0.10 - $0.15 / kWh

Windcell Panels* USD$0.03 - $0.05 / kWh

*Levelized cost of electricity based on 6m/s average airflows, 20 year lifetime ‡AWEA Global Market Study 2008
