Profitable technologies

• Small Diameter Timber (SDT) as a superb
  structural material for buildings and bridges of
  all sizes, shapes and applications.
• The LPSA generating profitable farm-based
  industries and products.

SDT Conclusions

• Diversification of income, esp. for family farm
  businesses.
• Vast resource (SDT) may spare remaining natural
  forests.
• Profitable forest mngmt / fire prevention.
• SDT as a basis for sustainable devpt.
• Major implications for construction, recycling
  and forest products industries.

Conclusions Dont Forget to Research Some of the
New Fertilizer and Construction
Technologies Because of their Energy Efficiency
Potentials, DOE Might be Potential Research
Funding Source.
