【正文】 nsor ? Throttle position sensor ? Knock sensor . has roughly 300 billion square feet of real estate China will add about 300 billion square feet of real estate within the next 15 years In a typical year, half of all new floor space in the world is built in China International collaborations that jointly develop new technologies ? Energy efficient and cost effective buildings ? Carbon capture and sequestration, Nuclear Energy US, China, Russia, and India have 2/3 of the world’s known coal reserves. International collaboration in carbon capture and storage will accelerate deployment of CCS technologies. 1. As with many countries, the US is pursuing both pre (. IGCC and oxyburn) and postbustion CO2 capture methods. 2. Our goal is to have mercial deployment of CCS begin in 8 – 10 years. CO2 capture and sequestration 3. Many new coal plants will be built before CCS is routinely deployed. We need an efficient capture technology from existing coal plants. DOE is supporting RD in numerous avenues (membrane technologies, phase separation, catalytic capture). IGCC power plant Integration of IGCC with chemical synthesis Polygeneration of Power and Chemicals may justify higher IGCC investments Nuclear Fission provides carbon free baseload power ? The nuclear waste issue is solvable. ? Nuclear proliferation is a concern and requires international cooperation. Gen III+ reactors (. AP 1000): ? Natural circulation ? Passive safety ? Decreased number of ponents means lower cost International collaborations that jointly develop new technologies ? Energy efficient and cost effective buildings ? Carbon capture and sequestration, Nuclear Energy ? Breakthroughs in renewable energy Pumped storage is 70% 85% efficient As wind and solar energy sources bee a greater part of our electricity supply, we will need a smart grid to respond to variable generation. Large scale energy storage will also be needed. Compressed air can be ~ 60% efficient Mj / liter Body Fat Kerosene, jet fuel Lithium ion battery 38 Mj/kg 43 Mj/kg Mj/kg 35 Mj/liter 32 Mj/liter Mj/liter Mj / kg Energy densities of chemical fuels and the best mercial battery A rechargeable battery that can last for 5,000 deep discharges and 5x higher storage capacity will electrify personal vehicle transportation Feedstock grasses such as Miscanthus can be energy crops. Nonfertilized, nonirrigated test field at U. Illinois yielded 15x more ethanol / acre than corn. 50 M acres of energy crops, plus agricultural and urban wastes can produce 1/2 of current US consumption of gasoline. Entire metabolic pathways were introduced into yeast to produce gasoline and diesellike fuels. Artificial Photosynthesis The first important step is to use sunlight to “split” water into oxygen and hydrogen. 2H2O + 4 photons ? O2 + 4H Earthrise from Apollo 8 (December 24, 1968) “We are now faced with the fact, my friends, that tomorrow is today. We are confronted with the fierce urgency of now. In this unfolding conundrum of life and history, there is such a thing as being too late.” Martin Luther King, 1967 謝謝觀看 /歡迎下載 BY FAITH I MEAN A VISION OF GOOD ONE CHERISHES AND THE ENTHUSIASM THAT PUSHES ONE TO SEEK ITS FULFILLMENT REGARDLESS OF OBSTACLES.
