Solar Tower - renewable energy green global warming
SolarMission Technologies (www.solarmissiontechnologies.com) and its Australian subsidiary, EnviroMission Limited (www.enviromission.com.au) produced this 5 minute video on the pilot plant in Spain. It is an older video (2000) but gives a decent understanding of the solar tower concept.
EnviroMission, Ltd. (US Market: EVOMY, Australian Exchange: EVM) is a renewable energy developer of sustainable "green" energy solutions for the energy market. EnviroMission aims to be one of Australia's leading producers of clean renewable energy. EnviroMission holds the proprietary rights to Solar Tower technology, a large-scale renewable energy technology based on simple fundamentals of physics -- hot air rises. Solar Tower technology has the potential to offer competitive renewable energy with equal reliability to fossil fuel generators.
A single 200MW Solar Tower power station will provide enough electricity to power around 400,000 households. The energy output will represent an annual saving of more than 1,960,000 tonnes of greenhouse CO2 gases from entering the environment when compared to brown coal emissions in Victoria. The greenhouse savings equate to the removal of approximately 500,000 cars from the road. The Australian Solar Tower project consists of six distinct phases, the first two of which (project optimization and pre-feasibility commercialization) have already been completed. The third phase (final feasibility), paving the way for the implementation of the next three phases (final design, construction, and commercial operation).

20% renewable energy by 2020
Raising the share of renewable energy from 8.5% to 20% in the overall energy consumption is a necessary contribution to the global fight against climate change and towards better control over our energy dependence. The various uses of renewable energy are examined: electricity through wind and hydraulic energies; electricity or heat through geothermal and solar energies; electricity, heat, and biofuel coming from biomass. The EU is a world leader in the use and deployment of technologies that exploit renewable energy sources, providing over 350.000 jobs and an annual turn-over of € 30 billion.

Renewable carbon negative energy
A simple experiment to prove with a low-tech downdraft gasifier you can produce charcoal and clean renewable energy as seen in the fist stage of startup.
When the charcoal layer had moved up the inner cone to reach the full diameter of the reactor, (Thus giving off the maximum amount of gas) I opened up the updraft air as well (Up/downdraft inspired by Agua Das's "Dasifier") as seen in the second clip. The only input was a small compressor that was using 3.4A of power.
Only innovation (If that!) was I coiled the compressed air tube inside the reactor to super heat the air. My thoughts here were the air would expand and this would reduce the load on the compressor as well as make the super heated O2 more ready to react with the syngas.
