Dupa Peak Oil Cuba o sa o duca cel mai bine. Adica o sa o duca la fel ca si acum.

PORT-AU-PRINCE, Haiti - It was lunchtime in one of Haiti's worst slums, and Charlene Dumas was eating mud. With food prices rising, Haiti's poorest can't afford even a daily plate of rice, and some take desperate measures to fill their bellies. Charlene, 16 with a 1-month-old son, has come to rely on a traditional Haitian remedy for hunger pangs: cookies made of dried yellow dirt from the country's central plateau.

Food prices around the world have spiked because of higher oil prices, needed for fertilizer, irrigation and transportation. Prices for basic ingredients such as corn and wheat are also up sharply, and the increasing global demand for biofuels is pressuring food markets as well.

The problem is particularly dire in the Caribbean, where island nations depend on imports and food prices are up 40 percent in places

While Havana's urban agriculture has taken on many forms, ranging from private gardens (huertos privados) to state-owned research gardens (organicponicos), Havana's popular gardens (huertos populares) are the most widespread and accessible to the general public. Popular gardens are small parcels of state-owned land that are cultivated by individuals or community groups in response to ongoing food shortages. The program for popular gardens first began in Havana in January 1991, and has since been promoted in other Cuban cities. In 1995, there were an estimated 26,600 popular garden parcels (parcelas) throughout the 43 urban districts that make up Havana's 15 municipalities.

Reyes Heroles told Reuters average daily production at Cantarell, in the Gulf of Mexico, would drop by 200,000 barrels over 2008

With the outlook for the US economy, and therefore for oil demand, growing gloomier, an production cut could be needed to keep oil prices at levels acceptable to OPEC, analysts say.

smog si aglomeratie.

sau cauta pe google "la smog", la texte si la imagini. sunt sigur ca are si zile mai bune, dar nu inseamna ca nu poate fi ca-n poza

Un proiect interesant care vizeaza folosirea directa a energiei solare pentru a produce hidrocarburi din apa si CO2 . Un avantaj important este ca astfel (cel putin in teorie) se poate recicla CO2 emis de termocentralele pe carbune pentru a produce combustibil pentru masini "normale"

sigur nu vroiai sa zici "blimpway, buna idee!"?

cat despre co2-ul captat de termocentrale, poti sa-l imbuteliezi si sa faci sifon

nu merge. bei sifonu, ragai si se intoarce co2-ul in atmosfera

dupa cum vezi, nu pastreaza pretul unde sa fie acceptabil pentru cumparatori (supply and demand), ci unde vor ei.

1st issue is easy to understand. They need a source of fuel to burn to cook, so they chop down trees. The idea of conservation and re planting what you've cut down is foreign. Its about basic survival, not thinking about tomorrow when you have to eat today.

2nd point, is that the US has flooded the market with cheap rice which the haitian farmers can not compete with. They sell their land and move to the cities for "work". Haiti used to support itself agriculturally but now is relient on handouts from the government in order to simply survive. The situation is desperate but the US hasnt helped. You do not help with handouts. Give a man a fish and he eats for a day, teach a man to fish and he will have food to eat for his life. Look at our welfare situation here, i know people need help, but to simply give people money DOES NOT HELP. Sure it seems like your helping and you feel good, but your not addressing the issue just the result.

Oh I guess one last thing. My dad told me that a lot of big companies are buying the rest of the fertile farmland to plant sugar cane for ethanol. Great you'd think, but the people are starving and yet they're investing in crops to fuel machines (for the US btw)

Alll of a sudden coal, so long the Cinderella of fossil fuels, is not just in demand but in desperately short supply. A chance combination of crises in big producing and exporting countries has pushed the price of European imports to almost $140 per tonne – double the level of a year ago.

.....
Coskata uses existing gasification technology to convert almost any organic material into synthesis gas, which is a mix of carbon monoxide and hydrogen. Rather than fermenting that gas or using thermo-chemical catalysts to produce ethanol, Coskata pumps it into a reactor containing bacteria that consume the gas and excrete ethanol.
.....
Tobey said Coskata's method generates more ethanol per ton of feedstock than corn-based ethanol and requires far less water, heat and pressure. Those cost savings allow it to turn, say, two bales of hay into five gallons of ethanol for less than $1 a gallon, the company said.
....
May Wu, an environmental scientist at Argonne National Laboratory, says Coskata's ethanol produces 84 percent less greenhouse gas than fossil fuel even after accounting for the energy needed to produce and transport the feedstock. It also generates 7.7 times more energy than is required to produce it.

pretul nu are cum sa fie acelasi indiferent de biomasa, cum zic ei

of, pana la urma tot de biologie tine procesul minune, si nu de fizica / chimie

At the zoo aquarium, selective breeding under exposure to chemicals and ultra-violet light made the Caulpera even hardier[1], and when it eventually found its way into the Mediterranean, it created an invasive species panic because of fears that it threatened to alter the entire ecosystem by crowding out other seaweed while being inedible to animals.
