The gasoline-electric hybrid news has come in at a furious pace at DailyTech over the past few weeks. Honda announced its intention to bring a small, sporty hybrid to market; Fisker announced its gorgeous hybrid sports sedan and GM yesterday showed off new hybrid full-size pickups and full-size SUVs.
Honda has a new fuel efficient vehicle of its own to tout and the word "hybrid" is nowhere to be found. The company finally pulled the wraps off the production version of its FCX fuel cell prototype -- now called the FCX Clarity.
Exterior design-wise, the FCX Clarity closely mimics the earlier prototype, but now features government-spec bumpers front and back and smaller wheels. Inside, the FCX Clarity uses a gauge cluster and heads-up display similar in fashion to the current Honda Civic. Otherwise, the interior looks rather normal if you can get past the overabundance of silver-painted plastic.
When it comes to the powertrain, the FCX Clarity uses a 100 kW V Flow fuel cell stack which is 65 percent smaller than the one used on the first generation FCX. Other powertrain components include a 171-liter, 5,000-psi hydrogen fuel tank, a lithium-ion battery pack and a 95 kW (127 HP) electric motor.
According to Honda, the FCX Clarity is good for an equivalent of 68 MPG and has a range of 270 miles. Also, since the FCX Clarity is a fuel cell-powered vehicle, there are no CO2 emissions -- the vehicle's only emission is water.
"The FCX Clarity is a shining symbol of the progress we've made with fuel cell vehicles and of our belief in the promise of this technology," said American Honda president and CEO Tetsuo Iwamura. "Step by step, with continuous effort, commitment and focus, we are working to overcome obstacles to the mass-market potential of zero-emissions hydrogen fuel cell automobiles."
The FCX Clarity will see limited service in the Southern California area beginning in summer 2008. Customers will sign up for a three-year lease at price of roughly $600 per month. Honda also notes that the FCX Clarity qualifies for a $12,000 IRS tax credit.

quote: Abundance of Radioactive Elements in Coal and Fly Ash Assessment of the radiation exposure from coal burning is critically dependent on the concentration of radioactive elements in coal and in the fly ash that remains after combustion. Data for uranium and thorium content in coal is available from the U.S. Geological Survey (USGS), which maintains the largest database of infor-mation on the chemical composition of U.S. coal. This database is searchable on the World Wide Web at: http://energy.er.usgs.gov/products/databases/ CoalQual/intro.htm. Figure 1 displays the frequency distribution of uranium concentration for approximately 2,000 coal samples from the Western United States and approximately 300 coals from the Illinois Basin. In the majority of samples, concentrations of uranium fall in the range from slightly below 1 to 4 parts per million (ppm). Similar uranium concentrations are found in a variety of common rocks and soils, as indicated in figure 2. Coals with more than 20 ppm uranium are rare in the United States. Thorium concentrations in coal fall within a similar 1–4 ppm range, compared to an average crustal abundance of approximately 10 ppm. Coals with more than 20 ppm thorium are extremely rare. During coal combustion most of the uranium, thorium, and their decay products are released from the original coal matrix and are distributed between the gas phase and solid combustion products.
