  1. Re:Maybe a horrible idea on Urging Congress to Cancel the Ethanol Tariff · · Score: 1

    I'll admit I'm not well informed on the issue. Here are a couple of questions anyway:

    How closely are you watching? The sugarcane fields could easily have been jungle 15 years ago. Are you sure they weren't?


    Let me take these. I am a Brazilian and have some familiarity with the theme.
    The sugar cane plantation in Brazil is concentrated in two regions. #1 is the State of São Paulo, SE Brazil, the most populated area of the country. #2 is the State of Pernambuco, on the NE coast. Both of these states are home to the oldest towns in Brazil: it is where Portuguese colonization begun. The city of São Vicente, on the coast of the State of São Paulo, was founded in 1580, if I am not mistaken. The City of São Paulo itself is over 400 years old. Olinda, in the State of Pernambuco, was also one of the oldest areas of colonial exploration in Brazil -- it was disputed between Dutch and Portuguese settlers in the 1600's . At the time both the Dutch and the Portuguese were fighting for sugar cane plantation land. After expelled, the Dutch colonist went to the caribbean to (you guess) grow sugar cane. Soo... what I mean to say, the sugar cane areas were not deforestated 15 years ago. More like 150 years ago or, in some cases, 400 years ago.

    Both Pernambuco and São Paulo are thousands of miles from the Amazon rain forest, by the way (which is of course huge, but not the whole of Brazil -- in fact very little of the Brazilian population is in it or close to it).

    Could the land being used to grow sugarcane be used to grow food otherwise? Is land being cleared to grow food so other land can be used for sugarcane?

    Of course the land could be used to grow food. But Brazil is a major exporting country for most food items already, and stopping with sugar cane would only change the profile of the exports. Land is being cleared, you are right, to grow food -- soy beans and cattle are the frontier -- but the advance is much more in the semi-arid "cerrado" region (western Bahia state, for example) and in the "Pantanal" marsh land in the Brazilian mid-west (Mato Grosso and Mato Grosso do Sul states) -- these are NOT the amazon rain forest. As the previous poster said, unfortunately the amazon is being brought down much more for the wood itself than for building productive agriculture.

    And it is not for the lack of laws -- if I may add. The wood extraction happens in indian reservations, national parks and government owned land illegally, protected often times by gun-holding criminals and corrupt authorities (wild west memories, anyone?). In fact the government laws sometimes hurt what they are trying to protect -- a tropical agriculture that could take place in the amazon rain forest would be palm trees (for palm oil, bio diesel, etc.). However, since the amazon rain forest is protected by law if you have 100 acres in the forest you can only bring down 10%-20% of it to grow other things -- which nobody finds interesting to do. In the end, if lawful ways are not economical, the unlawful way wins.

    The answers to questions like these aren't easy or clear. I certainly don't have them.

    Information exchange is a beginning. Take a look at maps of the country, look for São Paulo State, Pernambuco and the Amazon Jungle. You will see what I talked about. Brazil is larger than the continental USA, and tremendously varied in terms of climate, soil, vegetation, demographic and income distribution.

    So the tricky part is getting Brazil to reduce their own tarriffs at the same time. The WSJ article is desperately short on this aspect of the bill, and how the Brazil market currently stands tarriff wise.

    You are aiming at the wrong direction. Brazil is extremely competitive in virtually all agricultural products, and have comparatively little import tariffs for those things in place. Also consider that Argentina, just south of the border, complements with temperate/mediterranean products what the tropical/temperate agriculture of Brazil cannot supply.

    Fact of the matter is, with the exception of the American Sugar/Ethanol lobby, which protects an inefficient sector, the United States usually sits on the same side of the table as Canada, Australia, Brazil, Argentina and most other Latin American countries when it comes to negotiating lower agricultural tariffs. On the other side of the table are highly protective Japan and Europe -- and that's where you should be aiming at as a potential market.

    Of course as the Chinese and the Indian economy grow all of these potential (or actual) "agricultural powers" should not fear the lack of a market.
  4. Re:No source for 7x number on Urging Congress to Cancel the Ethanol Tariff · · Score: 1
    Interesting post. Let me add to your point #4 with some information from Brazil, where properly designed ethanol engines have, in fact, been built for a while.

    4) Ethanol has less power per volume then gas. That means those flex fuel vehicles are going to lose mileage AND power on E85. A proper E85+ designed engine could improve the power issue (Ethanol's higher octane rating allows for higher compression, which leads to more power and better efficiency).

    It is not true that ethanol engines have less power, quite the opposite. This is a fact taken into consideration by anyone shopping for an auto in Brazil in the past decade. Consider for instance this article discussing GM's Astra Multifuel, a vehicle launched in the market in September 2004, and which runs on a choice of three fuels: Gasoline, Ethanol, and Compressed Natural Gas. I drive one of these Astras myself, though without the CNG option installed.

    The article is in Portuguese, and I quote the interesting bit:
    Potência máxima com gasolina: 121 cv a 5.200 rpm.
    Potência máxima com álcool: 127,6 cv a 5.200 rpm.
    Potência máxima com GNV: 105,8 cv a 5.200 rpm

    Torque máximo com gasolina: 18,3 kgfm a 2.600 rpm.
    Torque máximo com álcool: 19,6 kgfm a 2.600 rpm.
    Torque máximo com GNV: 16,4 kgfm a 2.600 rpm.

    I guess the above can be understood without BabelFish. Keep in mind that "cv" means "hp" (cavalo vapor = horse power): the same engine on ethanol (álcool) gets 5.4% more power and 7.1% more torque.

    Never having thought about why (I am an electrical engineer, not mechanical) I googled a bit and found an interesting explanation. It is also in Portuguese, but I translate below the interesting part:
    O álcool hidratado utilizado como combustível no Brasil tem duas particularidades: alta resistência à detonação (como se tivesse alta octanagem, embora o álcool não possua octanas) e baixo poder calorífico (gera menos energia na queima que a gasolina). Em função dessas características, o motor a álcool pode utilizar taxa de compressão mais elevada, mas requer uma relação estequiométrica diferenciada, ou seja, a mistura ar-combustível tem de ser mais rica (com mais combustível) que no motor a gasolina. Na prática, isso significa que o motor a álcool pode obter mais potência e torque -- o que não ocorre em alguns casos por simples escolha do fabricante --, mas consume mais combustível.

    Translation:
    The hydrated alcohol used as fuel in Brazil has two peculiarities: high resistance to detonation (as if it had high octane, though alcohol does not possess octanes) and low calorific power (less energy generated compared to the same amount of gasoline burned). Due to these characteristics, the alcohol (ethanol) engine can use higher compression, but it requires a differentiated stechiometric relation, that is, the air-fuel mixture has to be richer (with more fuel) than in the gasoline engine. In practice that means that the ethanol engine can get more power and torque -- when it does not is due to a choice from the manufacturer -- but it uses more fuel.

    Cheers...

    Indeed, by adding more rules and systems, you can drive away more casual players because they have no chance of understanding what is going on and making reasonable decisions.

    Good point. I agree with it, in general, but not when it is applied to RPGs, in particular. If the game is the rules, and the story is only an excuse or a spice (for instance, in Settlers of Cattan, other classic board games and even, dare i say, RTS games such as StarCraft and AoE), then a lot is lost and nothing gained when going for an extra ounce of realism.

    However I understand RPGs are a distinct game concept which brings to the forefront narratives, descriptions and (an illusion of) the widest, true to real life, range of decisions and paths. Knowing much about the specific stats would deviate players from the "what would I do if I were there" mood, and close the door to players experimenting with the world. I can imagine someone finding a new weapon and not knowing before hand whether it is better or worse than the old one, but having an intuition (from the context and the description) on whether it is (or isn't) and later on perhaps perceiving (with usage) the truth. Always learning in a qualitative, not quantitative manner.

    In DnD dices are just a way to keep the story going, and a way to add a level of impartiality that no human DM could achieve without them. The fact that dice rolls are visible to the player in PnP D&D does not help the Role Play at all. IMHO if more complicated stats can lead to a greater probability of players believing that the narrative "feels right", then let them be.

    Having played way more games of risk online on the web than Id care to admit I have rationalized the following principles as the usual strategy for playing with/against humans in the "conquer the world" usual rules. I think it describes very well the plot in most games among experienced risk players, and unfortunately for the sake of the fun it also means these games draag until someone loses their patience and either abandons the game right away or does it by breaking principle number 4 below.

    1) Pick a continent and signalize it as being yours, by concentrating troop deployment there. You can choose the region as the one where you have proportionally more starting territories, and where your opponents have few. This usually happens in the first (simultaneous) troop deployment cycle. If you are lucky, you will be the sole player claiming a continent. (this works for all continents except Asia).

    2) Most of the time prefer defense, and patience, instead of offense. If for instance someone else has a troop stack in the region you want, reinforce around it (except a single way out) and wait. Only make sure you grab a territory and a card every turn. The usual exception for the defense rule is opportunistic: if for instance you trade cards and believe you can grab and defend a territory, attack and definitely do it.

    3) When you are attacking (in ealy-mid game), pick one opponent to attack, try not to have two fronts. Do not stop attacking that opponent until he is out of the game, or completely disconnected from you on the map, as he may (being human) hold on only to screw you up at a critical point later. If a second front opens up early, however, consider immediately retreating your forces from your first targets territories, and concentrating all troops in defeding your base-continent.

    4) In mid to late game stages, be extremely careful when deciding to attack. It is very usual for end games to be a stale mate, with troops piling up and up and up among (tipically) three remaining players. In that scenario, the only strategy for winning is trying (hoping, waiting) not to be the first one being attacked nor the first one attacking, since those two will burn their troop piles among themselves leaving the third player with full forces to ride to the victory. If, in turn, you *are* attacked, in that stalemate scenario, then either close your border back, reinforce and wait, or go full force and try to hurt your attacker as much as you can (possibly at the same time opening up room for said third player, as having his favor may mean he will let you be the last one surviving before he conquers the world).

    5) It is interesting that if you are playing for points (and depending on the scoring system) then you can change from a strategy of domination to a strategy of survival, if you see you are falling behind in strength. That may mean putting all of your reinforcements in a single territory, and moving that pile to (usually) Asia. Then just wait and keep reinforcing. People will tend to avoid attacking you if your pile is large enough until the last thing they do in the game. And while they are not attacking you they may be attacking each other so much that they may get weak and leave you some room to aspire for domination. But be happy as you can almost always guarantee being the last survivor before the winner dominates the board.
