I have been trying to understand the fuel cell market.  This is an interesting description.

 

A fuel cell is a device that converts the chemical energy from a fuel into electricity through a chemical reaction with oxygen or another oxidizing agent.[1] Hydrogen is the most common fuel, but hydrocarbons such as natural gas and alcohols like methanol are sometimes used. Fuel cells are different from batteries in that they require a constant source of fuel and oxygen/air to sustain the chemical reaction; however, fuel cells can produce electricity continually for as long as these inputs are supplied.

The first fuel cells were invented in 1838. The first commercial use of fuel cells came more than a century later in NASA space programs to generate power for probes, satellites and space capsules. Since then, fuel cells have been used in many other applications. Fuel cells are used for primary and backup power for commercial, industrial and residential buildings and in remote or inaccessible areas. They are also used to power fuel-cell vehicles, including forklifts, automobiles, buses, airplanes, boats, motorcycles and submarines.

There are many types of fuel cells, but they all consist of an anode, a cathode and an electrolyte that allows charges to move between the two sides of the fuel cell. Electrons are drawn from the anode to the cathode through an external circuit, producing direct current electricity. As the main difference among fuel cell types is the electrolyte, fuel cells are classified by the type of electrolyte they use followed by the difference in startup time ranging from 1 sec for PEMFC to 10 min for SOFC. Fuel cells come in a variety of sizes. Individual fuel cells produce relatively small electrical potentials, about 0.7 volts, so cells are “stacked”, or placed in series, to increase the voltage and meet an application’s requirements.[2] In addition to electricity, fuel cells produce water, heat and, depending on the fuel source, very small amounts of nitrogen dioxide and other emissions. The energy efficiency of a fuel cell is generally between 40–60%, or up to 85% efficient in cogeneration if waste heat is captured for use.

The fuel cell market is growing, and Pike Research has estimated that the stationary fuel cell market will reach 50 GW by 2020.[3]

The power disc company with their eflow technology is very coo.  Their founder and president is an amazing inventor and driver who embodies Thomas Edison principles of “If there is a better way to do it find”  Find out what the world needs and go build it. 

Looking forward to getting further up to speed on it,

A global tour of the emerging-markets currency crunch

Deano's Thoughts:

Interesting dynamics in emerging markets. Was with a + billion real estate asset manager (owner) and he mentioned he was keen to own assets in Australia. I see jakarta as a place long term to be also.

The big markets news at the end of last week was the plunge of Argentina’s peso. The sell-off came as many other emerging-market currencies were already sliding:

What’s driving these trends is the intersection of the US Federal Reserve’s decision to slow its bond-buying stimulus—the so-called “taper,” which has been fueling a sell-off in emerging markets since early last summer—with a variety of more local problems, ranging from troubled economic institutions to political unrest and bad economic data in China. But a smart note from London’s Capital Economics, highlighted by the FT’s Izabella Kaminska, provides a helpful taxonomy of what different emerging economies are going through and, more importantly, whether one country’s problems could prove contagious to others, as happened during the currency crises of the 1990s. We’ve broken it down with the following maps.

In these three countries, trouble comes because of “serial political mismanagement.” Venezuela and…
