Basic premise is the USA could be energy independent in 10 years by going with alcohol rather than petroleum based economy. He suggest using both Ethanol (but admits to replace all USA oil consumption would require all 4x current agricultural output) and methanol. I have not heard much about methanol. It is about ½ as energy dense as gasoline (and 2/3 as much as ethanol). But it can be made from Coal and Natural Gas very easily. It costs around $0.93/gallon currently, so without subsidy it would be $1.86 per gallon. Which is slightly higher than current (March 2009 price for gasoline is $2.00 at the pump but includes a $.050 road taxes which leaves gasolean about $1.50). When this book was written Gas was at $3.00, so Methanol was very competitive. The best part of the book covered the Brazilian history. Basically, the country went to Alcohol from Sugar Cane in the 70s due to the fall of sugar prices (70% drop in prices in 1975) and the rise in oil. First, they mandated 10% ethanol mix. Then 15% to a maximum of 24% for conventional vehicles. Then they started to push ethanol cars. The state oil company was ordered to add ethanol pumps at each service station. Then oil prices skyrocketed in 1979 and then the market share of ethanol cars went to 30%. By 1986 oil prices crashed and made oil cost less than ethanol. Brazil was in trouble with the IMF by subsiding ethanol but kept a 20% mixture. Now they are pushing flex fuel vehicles and now these vehicles at 100% of the new car sales. Brazil is now a net exporter of energy. Another interesting piece was on Hydrogen as a fuel. Too expensive to generate (There is no hydrogen free in the environment. It is bonded with Oxygen (water) or Carbon. Hydrogen creates a lot of energy by mixing with Oxygen, so you need energy to separate it.) The problem of the book is the politics and economics. Most of it is re-treading ground covered by many others - Saudi wahibilism and Saudi support for Madras’s worldwide. It then covers Saudi influence on USA politics. Weak research, mostly secondary sources if they are footnoted at all. Further the actual technical stuff seems to have been pulled from another book titled, "The Methanol Economy", but have not read the original to confirm.

When I first saw this book, I was at first hesitant to buy it since Allison Van Diepen past books have all been more on the real life side of Young Adult. Which isn't my cup of tea usually; I prefer more of the fantasy/supernatural books. I read the excerpt and liked it. I am so glad that I bought it. As soon as I cracked open the book, the characters are highly relatable, so are the experiences of Nicole, the lead character. Just like Van Diepen's past books, the slang that is used in the book fits right in and doesn't seem out of place (I have no clue how Van Diepen does it. Most author's I read who use slang in their books, it's very out of place and doesn't seem to flow with the book. I must point out that I've read Van Diepen's book Snitch and in the beginning in the book it was heavy with the Slang, this is not the case in this book.) However, the main character is part of a break dancing crew so there's terms for the moves that they do (i.e. 'apple jacks', 'coffee grinder', 'jackhammer', etc.). I for one have seen breakdancing done before but I have no knowledge of the moves, and so didn't know what they were doing. But Van Diepen wove in other terms that'll make sense for someone like me. For those who love the vampire genre this is an interesting take on it. Some of the characters are sort of like vampires, but not really. They don't go around sucking blood like the western view of vampires, her vampires are Eastern ones. Where they "absorb" the energy/soul of a person. I highly recommend this to any fan of young adult books be it the ones who like the real life ones or the fantasy/supernatural.
