Ray Kurzweil was on CSPAN-2 the other day, sponsored by the Council on Foreign Relations. He said that the growing science of solar nanotechnology could provide 100% of our energy requirements by 2030 or so.
More and more, it looks like there WILL be a substantial technofix to our energy problems coming from emergent nanotechnologies with solar and other applications.
NO WAY will this scientific/technological explosion we all live in be reversed by an empty petrol pump. Things will just change...not that such a paradigmatic change could not produce some violent wrenching, of course - like maybe a war in the Middle East.
Emerging Uses of Nanotechnology

')
In 2004, governments, corporations and venture capitalists spent more than US$8.6 billion worldwide, and national and local governments across the world invested more than US$4.6 billion, on nanotechnology R&D. This is the last year that governments will outspend corporations on nanotechnology activity as the focus shifts from basic research to applications development. Approximately 1,500 companies worldwide have announced nanotechnology R&D plans. Eighty percent of them are start-ups, 670 of which are in the United States. A key driver is energy independence.
In the United States, activities related to energy include (key agencies in brackets):
· Energetic materials for propulsion, explosives (DOD)
· Catalysis, fuel cells, hydrogen (DOE)
· Advanced power systems (IA)
· Energy conversion and storage for space (NASA)
· Materials science and engineering (NSF)
· Manufacturing processes and equipment (NIST)
· Biomass conversion, hydrogen production, distributed power (USDA)
American nanotechnology companies are working on catalysts and photovoltaics. Nano-stellar is developing highly-efficient platinum nano-composite catalysts for automobile emission control, fuel cells and chemical industry applications. The next-generation technology will finally make solar power competitive. The new photovoltaics use tiny solar cells embedded in thin sheets of plastic to create an energy-producing material that is cheap, efficient, and versatile. Massachusetts-based Konarka expects to deliver its first commercial solar cells designed for use with consumer electronics like laptops, by the end of 2004.
There are opportunities to capture the benefits of nanotechnology in Australian energy through:
· Reduced reliance on fossil fuels and increased use of renewables, in particular solar energy and hydrogen
· Development of solutions tailored to Australia, e.g. distributed energy storage and production
· Growth of companies to manufacture components, catalysts and cells, based on new technologies
· Integration with specialist manufacturing industries, in particular medical and automotive.
PHOTOVOLTAICS (Dr Caruso)
Energy is an essential element for our livelihood and for the advancement of humankind. The majority of our energy is derived from fossil fuels, which we know to be a finite resource that has had a devastating effect on our environment. For some time now there has been a quest for cheap, reliable alternative energy sources which are sustainable. Renewable energy sources include wind turbines, hydropower, and solar power. This presentation focusses on photovoltaics, where light is used to produce electrical power.
