It won't be like pulling into a petrol station, but perfectly viable if you were to stop at the supermarket and charge up, or stop somewhere for dinner and charge up. Parking meters could become useful. |

| 1192370 | 2011-04-07 07:04:00 | I think I read somewhere that the petrol engine only had 20% efficiency so not very efficient. Its a complex thing to measure. As I understand it, diesel, kerosene, and aviation fuel are the most efficient, followed by petrol. Even Hydrogen is way down the scale. Efficient means the amount of energy you get per litre of fuel. It may very well be only 20% of the total energy, I don't know. But the fact remains that good old hydrocarbons still provide the biggest bang for buck. Hydrogen is fashionable and may become the next big thing. However making the stuff requires electricity in the first place so lots of energy is used and wasted simply getting the H to the pump. FYI biofuel is either a nett energy loss of 20% or slight gain of 20% depending upon who you believe. Diesel/petrol is 1400% gain over the effort to get and refine it. Damned hard to beat so far. |

| 1192372 | 2011-04-07 21:05:00 | McDermott International Inc. (NYSE:MDR) recently decided to separate B&W, on of its subsidiaries, from the company's other engineering interests. The Tennessee Valley Authority (TVA) has designated 760 acres near the Oak Ridge National Laboratory in eastern Tennessee as a site for a future power plant. This will probably become a main testing location for the mini reactor. But I find a third development the most interesting... It is Santa Fe-based Hyperion Power Generation Inc., a spin-off company from the Los Alamos National Laboratory. Hyperion is barely out of an incubator stage, yet already has 120 orders for its Hyperion Power Module (HPM). Shipments should begin by 2016. It is privately held now, but it needs more capital to expand activities. That will require it to go public. The company should file engineering specs with the NRC this year. The Hyperion units are the smallest yet - about the size of a hot tub. Each HPM can provide electricity for eight to 10 years before refueling... power 20,000 homes... and generate as much as 25 to 100 MW in serialized installation. They are sealed at the factory, making accidents virtually impossible, and can be either above or below ground. With a price tag of $35 to $50 million, the HPM is also inexpensive enough to revolutionize village life in most areas of Africa and Asia by providing both power and the ability to purify water - readily available technology exists to clean dirty water. What undeveloped areas lack is the ability to power that technology cheaply. It is little wonder, then, that both continents are directing considerable interest in Santa Fe these days. Of course, the advances coming from Toshiba, B&W, Hyperion, and other competitors certain to enter this market, have direct applications here at home. We are witnessing the miniaturization familiar to computer users. If we could liken a conventional nuclear plant to a mainframe, the minis seem the nuclear industry's version of a laptop: Almost anyone can afford one, and you can take it anywhere. |
