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
A new type of wind power: The Windbelt technology
Prototype 1-meter WindcellTM
units undergoing validation
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
