$7 billion in nanotechnology will make autos leaner and cleaner
Thursday, February 8, 2007 at 8:27PM
By 2015, experts predict revenues from nanomaterials in automotive applications will reach almost $7 billion. Ford is conducting nanotechnology research with Boeing and Northwestern University to create lighter weight metals and plastics with greater strength, ultimately helping improve safety and fuel economy. And Tesla Motors is working on an electric sedan using Nano-Safe batteries that will sell for $50,000.

UN weighs nanotechnology's environmental risks and benefits
Nanotechnology and the Environment. It’s a balanced synopsis of nanotech risks and benefits along with some recommendations for the future. Here I’ve boiled it down to its basics:
“Nanoparticles have the potential to deliver environmental benefits both in production processes and in products. Nanomaterials can substitute for conventional materials that require more raw material, are more energy-intensive to produce, or are known to be environmentally harmful. New nanotechnologies seem poised to enhance environmental protection and improve pollution detection and remediation.”
BENEFITS:
Replace conventional materials that require more raw material or energy to produce
Reduce use of chemicals and materials, particularly those with negative environmental impacts such as pesticides
Build environmental sensors of higher sensitivity and lower cost
Reduce industrial and vehicular emissions
Produce photocatalytic surfaces that attract and neutralize pollutants
Produce self-cleaning surfaces
Create longer-lasting, safer batteries
Create more efficient, less expensive solar cells
Enable better storage of emission-free fuels
Improve water purification
Enable room-temperature industrial processes (saving energy as compared to current high-temperature processes)
Create higher strength, lighter weight materials
RISKS:
Could be highly reactive due to large surface area and small size
Long-term stability in the environment unknown
Ability to remain airborne due to small size and light weight
Potential interaction with aquatic ecosystems and soil unknown
Potential for biodegradability unknown
Known toxicological effects of some nanoparticles on some plants and animals
RECOMMENDATIONS:
Apply life cycle analysis to nanomaterials to determine long-term effects
Improve ability to measure, detect, and differentiate nanoparticles in the environment
Further study toxicological effects
Assess current methodologies for assessing ecotoxicological effects
Evaluate environmental impacts of engineered nanomaterials prior to mass production
Standardize nomenclatures and test protocols
Foster cooperation between public and private sectors, developed and developing nations, among developed nations, and between governments and intergovernmental organizations
Enhance regulatory and environmental organizations’ awareness of nanotechnology benefits and risks
Support sustainable development through nanotechnology
Share existing private sector best practices in nanotechnology risk management
Educate the public about nanotechnology
