Publisher's Summary:

The smallest flowering plant, on Earth, is one of the most powerful, and widespread: duckweed. Usually, considered a nuisance, duckweed, upon close examination, is an impressive crop, in photosynthetic value. Ethanol, an industry dominated by the Corn Industry (King Corn), faces many challenges, including large water draws, rising fertilizer costs, large diesel fuel bills, and unintended impacts on Food markets. Corn, as a choice for ethanol production, pits food, versus fuel, for agricultural resources, increasing stresses between fundamental markets. An ideal source of biomass, for ethanol production, would not be a food crop, rather, a waste-crop. King Corn, dominates current domestic ethanol production markets, worth billions, each year. Supported with Federal Farm Subsidies, worth billions of dollars annually, the corn industry dictates the US ethanol markets, using Corn as the principle feedstock crop. At first glance, Corn, is an odd choice for ethanol production. Corn, began as a wild seed crop, domesticated by ancient man. Before the modern age, thousands of years of selective breeding, produced a Corn rich in proteins, and high in nutritional value. Modern Corn, has been engineered to go "the other direction," and reduce Corn's Protein, and increase Corn's Starch (Carbohydrate) production. The "Starch" in corn, is used for Ethanol production, and other by-products, such as Corn Syrup, and Distillers Dried Grains and Solubles (DDGS). Duckweed, is a choice for bulk biomass, which offers significant advantages over corn. Duckweed advantages include, lower energy costs, lower water resources, lower fertilizer costs, doesn't require valuable farmland, doesn't compete in Food markets, has higher Starch yield, per acre. Duckweed, in a controlled environment, can be grown, year round, and in diverse locations.

Needs work.

Poorly written!

and certainly better than using a food crop like corn to produce ...

Illuminating! Fermenting Duckweed seems to be more promising, and certainly better than using a food crop like corn to produce Biofuels. Many good ideas regarding revenue streams ...a good read and very informative on many levels.

Non truths spoken here.

Don't believe every word in this book.

nothing about growing, harvesting and refining duckweed into ethanol. Very vague, non practical, full of bla-bla-bla

If you expect this book contains practical guidelines and information - it does not.

The author is very hyped up by the idea of using duckweed for ethanol production but does little to explain and give practical advice on how to build such process. The essence of the whole book can be expressed in one sentence: "duckweed is a next gen. energy crop". Each new page and chapter repeats this claim over and over again.

Constant repetitions and no exact information about duckweed growing and harvesting techniques. The book lacks explanations how to increase starch content in duckweed to get more sugars.
