Cabot Corp (CBT) has developed a relatively inexpensive method of making aerogel insulation. Aerogel insulation is a translucent insulation with good qualities. With Kalwall corp, they are using it effectively. Couldn't find anything for Kalwall, but CBT is listed and currently paying 5.8% dividends. Alternate investments that pay dividends aren't that common. This could be well worth some research.

BenSolar: France is importing energy from Britain because soaring temperatures have forced the shutdown of 1/3 of it's reactors. http://business.timesonline.co.uk/tol/business/industry_sect... ... Interesting! Thanks for the reference.

Batteries made hydrogen storage obsolete before the first hydrogen fuel cell was ever built. Hydrogen has poor energy density and poor efficiency compared to direct electric drive from battery storage. Elan Speaking of which: http://watch.bnn.ca/trading-day/july-2009/trading-day-july-2...

This appears to be due to crippling environmental regulations to me. No doubt there is a wide array of economic activity around those rivers that would be killed off without those regulations. Deregulators only seem to think in the narrowest of contexts.

I am in favor of environmental regulations if they actually protect the environment. I am generally against such regulations if their only purpose is to shut down industry. I found a statistical study of French river water temperatures titled: " Is there a trend in extremely high river temperature for the next decades? A case study for France. The pdf of the study can be read here:...

This may not necessarily be a bad consequence. Stress relieved in a fault under predictable conditions would take some uncertainty out of the Earthquake when and where and possibly have a distributive effect through the entire fault line. From the same article: Do these little earthquakes help relieve any building pressure to help stave off larger quakes? Unfortunately that's a myth.

Note that a home geothermal system puts heat into the ground in the summer. In many climates, especially when one can open the windows in the correct season, it is actually an active seasonal heat storage system. I hate the term geothermal in this case because it can be confusing. A much better descriptor is a ground source heat pump, as opposed to an air source heat pump. Ground source heat pumps gather solar energy that is stored in the...

Indeed, home based "geothermal field is very very different that the deep, very deep into the magma areas geothermal of companies on the large scale such as HTM, & Tim's fave NGLPF.OB, among others. Night & day, oranges & apples. Even RZ is profoundly different that ones back yard laid out grid heat exchange array. There will need to be a defining of terms so people will be educated properly.

"1. If cap and trade is approved, railroads may be called on to reduce use of diesel fuel. A non-carbon fuel like hydrogen makes the most sense." Railroads are 5 times more efficient than trucks. Why wouldn't you look to 1 million trucks, spewing out 5 times more diesel fumes, first? Oh, you like 'big targets'? Second, if you want to cut down carbon, since you have no source of hydrogen from non-carbon...
