New advances made in hydrogen fuel cells

The best hope for bringing the hydrogen-fueled automobile to the American roadway may be a technology that is invisible to the naked eye. The technology is in the form of tiny graphite structures that together act as a sponge to absorb and store hydrogen in the fuel system of the automobile. Onboard storage of hydrogen gas is the major obstacle impeding the progress and wide-scale commercial production of the hydrogen-powered vehicle, which many view as the next generation in energy-efficient and environmentally friendly road transportation. The graphite structures are a product of the burgeoning field of nanotechnology. Engineers design the structures at the molecular level, working in scales as small as millimeters and nanometers. The engineers stack the fibrous platelets one atop the other, leaving the optimum gap between the wafers; then they arrange the chemistry so that hydrogen molecules are absorbed in the graphite. The nanostructures are extremely porous, like a sponge, allowing them to absorb large capacities of hydrogen until fully saturated. Experiments demonstrate that the hydrogen storage in graphite nanofibers is safe. Another method of hydrogen storage derived from nanotechnology involves carbon nano-tubes. With carbon nanotubes, engineers arrange carbon platelets in different configurations. Research has shown the carbon nanotubes to display strong hydrogen storage capabilities. The contribution of nanotechnology to hydrogen storage is timely, as automobile companies work to advance fuel cell technology amid growing public sentiments to develop alternative forms of energy. Despite the promise of nanotechnology in automobile fuel cells, additional research is required to refine graphite nanofibers and carbon nanotubes and to develop cost-effective means to manufacture the advanced structures. The Nanotechnology Institute at the American Society of Mechanical Engineers (ASME) strongly supports research in nanotechnology and is dedicated to narrowing the gap between theoretical science and real-world applications. Among other programs, the institute organizes forums that bring together the technical community and general public to review developments in the field.

Live poker pros and cons of participating in a tournament

: If you have had enough of playing poker with friends or with playing it online and winning some money and then losing some money to only win that money back again, then you have reached the stage in your poker playing experience where you need to start entering live tournaments. That is the real deal. No more long hours in front of the computer, no more feeling guilty for taking your friends' money: you are now ready to turn pro. But, before you do, here are a few things you must consider: 1) One of the big differences of playing in a tournament is that you need to pick you hands carefully. Spend most of your time throwing your cards away at the right beginning. If you see that your cards won't amount to much, fight the urge to exchange most of them, and just hand them all in. This is what most tournament players do anyway. If you don't believe me, watch the others play. 2) Money you take with you to tournaments lasts for a much lengthier period than when playing with friends or online. This is one of the advantages of not playing every hand you are dealt. (Hint: You should do the same thing when playing with friends even though that then becomes boring.) 3) Do not sit to the left of the dealer. Ensure that there are at least two players between the dealer and the players to the left. Why? Only the first 2 players seated on the left of the dealer have to place the ante. Since, most of the tournaments involve ten players on each table, you save this much each time you play. This also means that each hand that you fold will mean that you have spent only half that of the lower limit. This amounts to three dollars in a two to four dollar rake tournament. 4) Take into consideration that the mere fact that you are away from home means that you will spend money on food and drinks. Try and get your own, but in any case keep it light. 5) Tournament dealers are not paid much, and so it' general practice to give them about three percent of whatever you win. Consider that all gambling halls and poker rooms also take a certain percentage but at least this comes from the money you win and so you don't feel it. 6) One of the other advantages of playing in a tournament is that you can use more money than you had. For instance, for a hundred dollar sit-in, many casinos and poker rooms will give you about five hundred in tournament chips to bet with. 7) If high odds and high risk is not what you are looking for you can take advantage of the late night satellite tournaments. These generally begin at one in the morning and since the number of players won't be high, you stand a bigger chance of winning. Conclusion: Playing poker requires tremendous skill as well as come luck. While you cannot depend on luck, improve your skills and your online casino or other kind of betting account will show a profit.
