Sven Biller svenbiller — good story, could've been great if it had a more solid backstory

Blake Mcwhirter studioblake — Really enjoyed this one. Granted, it did take a while to get into but once there it was a marvellous read. All the characters are equally engaging and there is not one where you think "oh no, not you again" and skim read for a couple of pages... Very gripping and moving with an important message - life your life to the full as the world will not stop and wait for you to catch up later.

Ataman Ataman atamana166 — The story moved forward in numerous ways, but many of the main characters we had been following in the previous books weren't present. I can understand the readers' chagrin at the 4th book now. Still, it did follow along with many of the favorites and new characters were focused on. But, you just have to read it to progress the larger plot. So, it was a good read in that way. You get a sense of where all of this is going now and I can almost foretell the final 3 books. But I have fatigue with this series now and I'll wait to read the next book in a little while. There are too many other books I want to read right now, as well. So, til we meet again, Mr. Martin.

Jim Dwyer jimbojetset — 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.
