Do We Take Water for Granted? [view article]
As is the status quo in our pandering pro-business United States Government Representatives zero preventative measures will be implemented and we the people will experience yet another horrific crisis of magnitude--even more horrific than the present energy crisis. We just cannot seem to grasp the concept of non-finite natural resources! Replygordon

Do We Take Water for Granted? [view article]
If history is any indicator of the future, acting on our water shortage will be similar to our acting on our fossil fuel energy/enviroment problems. Not much will happen until we are in crisis mode.That said, I hold a position in WTR and other such utilities. Most of these have been taken down in price during the past six months and present decent entry points. Reply

What about HOO? ReplyGlobal Warming Up to a Hydrogen Economy [view article]
Any high school chemistry student knows how to make H2 from H2O. It takes some familarity with thermodynamics and economics to appreciate the costs.A catalyst can only permit a reaction that is thermodynamically possible. No catalyst can make H2 from water without input of more energy than you get from making water from H2. The same applies to making carbon and oxygen from CO2. That energy has to come from somewhere. It would take a huge excess supply of nuclear, solar, wind, geothermal, hydro, or tidal power before one could consider a meaningful conversion of CO2 to C and O2 or of H2O to H2 and 1/2*O2.
How much consideration is being given to use of solar power and biomass (algea?) to use up CO2 and make O2? In Brazil they are making CO2 from forrests in order to make ethanol from sugar.
The idea of nuclear power to make electricity to make H2, pipe the H2 to homes, make electricity from H2 at the home, and use this electricity to heat the home seems to be, at the least, somewhat inefficient. As a matter of fact it seems like fuzzy thinking taken to a new extreme.

Hydrogen is the future! ReplyWater Investments: Staying on Land - For Now [view article]
Richard put his finger on the future for water:the need for progressive breakthroughs in the development of membrane technology in the desalinization process + running those plants on alternative energy. There are several companies, like Consolidated Water, that have already shown this to be a magnificent opportunity! ReplyWater Investments: Staying on Land - For Now [view article]
Stuart,Good points about water shortage issues.
The World Bank warns of "catastrophic consequences" if water use and supply are not brought into balance.
They say that worldwide we are "mining water" by pumping more water out of the ground than is being replenished -- and that once our pumping depletes the aquifers our pumping will be limited to the recharge rate (no statement about ability of desalinization to make up the difference, I suspect it can't keep up).
The impact of a future physical limits reducing water pumping rates would have direct impact on food production levels and related social unrest.
Apparently, even fossil aquifers (water trapped in geologic formations for which there is no replenishment) are being pumped in some cases.
Rivers are being diverted upstream to various uses, which causes conflicts with downstream users. Water wars are local now, but could enlarge to be between countries in the future.
About 70% of world water use is for irrigation, about 20% for industry and about 10% for residential use.
The world needs more efficient methods (such as drip irrigation instead of surface water irrigation, and recycling of industrial waste water for industrial reuse). The world also needs more desalinization capabilities.
As water shortages become more evident, there should be an increasing number of investment opportunities to benefit financially from those companies that will help solve the problem.
Utilities may not be the best option, but those technology companies that create solutions for greater water efficiency or the creation of more water supply from the oceans may be good opportunities.

Global Warming Up to a Hydrogen Economy [view article]
There are some important points to make here. First, the energy density of hydrogen is significantly less than current hydrocarbon fuels. And as some have pointed out, producing hydrogen is not cheap, nor is converting the present transmission infrastructure. Hydrogen does not make a practicable liquid fuel, which is what we need for aircraft.The production of carbon black (elemental carbon) is not produced by the Sabatier process; doing so requires a lot of heat energy and the technology does not scale well to small applications like cars.
It is not at all clear that hydrocarbon sources in the Earth are in short supply -- new sources (and very large ones) are being discovered on a regular basis; nor are they all in places beyond the shores of North America -- The US gets the vast majority of its imported oil from Canada and Mexico. The price rise we are seeing now is not being driven by US consumers, but by the success of capitalism in Asia.
The bottom line is that we need to increase the supply of energy sources, not reduce them. The best aspect of this blog's article is that it alludes to the capacity of innovative technologies that may reasonably permit the profitable recycling of hydrocarbon emissions -- this is a topic worthy of much study.

HYDROGEN CAN BE MADE CHEAPLY USING SOLAR , NUCLEAR , WIND , EARTH CORE TECHNOLOGIES AND WATER....NOW GET TO WORK! KHOSLA S SOLAR PROJECT IS THE ANSWER!!! ReplyGlobal Warming Up to a Hydrogen Economy [view article]
The Hydrogen Education Foundation is thankful for the balanced article published here at SeekingAlpha.com. Although, the transition to hydrogen is a complex issue, it is achievable and may be simpler than it appears.Hydrogen has been used for decades by other industries, such as agriculture, oil production and even food processing (ever heard of the term “hydrogenated?” – take a look at a jar of peanut butter or the wrapper of a Starburst). In fact, more than 40 billion kg of hydrogen are produced globally each year with production plants located near or within every major metropolitan city in the US – enough to fuel 130 million fuel cell-electric vehicles annually. Since hydrogen is used to produce gasoline, the switch from gas to hydrogen to fuel our transportation is achievable and is a natural progression requiring no additional resources. Recently, General motors released a report describing just how a fueling infrastructure is possible in the near future: www.h2andyou.org/pdf/G....
One of the many benefits of a hydrogen economy will be its favorable impact on the environment. As is described above, natural gas offers the ability to guide us away from depending on oil and facilitates the adoption of hydrogen. While not 100% clean, even using hydrogen produced from natural gas will dramatically reduce greenhouse gases by more than 60% compared to current standards. Two of the leading fuel cell manufacturing companies, Ballard Power Systems and Plug Power, recently released a joint report that confirms fuel cells using hydrogen produced using natural gas can improve the environment by reducing greenhouse gases. The report is readily available at Plug Power’s website at www.plugpower.com/news....

Global Warming Up to a Hydrogen Economy [view article]
This article is exceptionally well written and shows the uncertainty of the true causes of climate changes and the many variables in play. The fact that humanity keeps growing and that there are natural weather trends that overlap human effects and make the controversy even more complex. The fact of the matter is that we don't really know what' s going on and have very little control over it.To me the whole discussion somehow misses the point that hydrocarbon resources are getting more and more scarce and it makes tremendous sense to embrace new energy technologies and advance them to a level that will support our civilization for the next millennium.
More important is the fact that countries like the US are ruining their economy having with such an unbalanced current account deficit caused by spending on the import of hydrocarbon energy.
Its time to seriously invest more in innovation and fundamental research on energy generation to give humanity more power over its own future.

This is one of the best explanations of the global warming controversy and the probable future of energy development. I want to remind the author to look into increasing albedo of ocean clouds as a way to reduce earth absorption of infrared. This would be implemented by "seawater droplet disseminators" that are floating barges equipped with atomizers of seawater that is transported to a level of 50 ft above the water surface and become nucleii of cloud formation. It has been observed that certain areas of the ocean, roughly located along the west coasts of continents are deficient of normal ocean clouds and would the the places where the barges are deployed. The barges would be powered by wave action power generation and switched on or off and relocated by satellite observation and communication. This may sound like a crackpot idea, but is a simulation of the normal method of cloud seeding which is wave action causing splashing and waves striking the shorelines. The calculations show that relatively few barges are needed, and when feasibility is demonstrated in one region, more barges can be replicated, providing a demand for the product. This would need to be funded by an overseeing global financial structure such as the World Bank, because there would be no direct economic return on any one company or country.The idea was originally proposed by a Harvard professor back in the 1980's, but has been only reconsidered in recent years. A series of papers are available at: ccc2006.ca/docs/Abstra...
I also want to see your comment on the Thai system being licensed by Petrobank of Vancouver. This is a means to reduce the viscoity of heavy oil making its recovery more complete and less expensive. The basic idea is to inject air into a region beyond the oil well and combust some oil underground. The oil well has a long horizontal bore within the oil bearing strata. The heat generated will liquify the oil and tars and the pressure from injecting air will force the oil up the main well bore. The CO2 generated is retained below ground thus preventing its release to the atmosphere. By the processes you mentioned in your article, it is conceivable that it could also be converted to methane when the well has ceased production of oil. This process is the basis for optimism about the Bakken Oil Formation recently identified in the northern Midwest states and Canada. Reply
