Natural Gas to hydrates for transport and back to gas

A while back I wrote a post HERE and HERE on collecting natural gas hydrates from the sea floor.  I was not really in favor of the idea because of the possible/probable dangers.  For good or bad like drilling at 5000ft for oil, extracting these frozen naturals gasses is going to happen so might as well examine the effects..

One of the often cited problems with natural gas as an energy source is that they are hard to safety transport over long distances because of the volatile and hazardous properties of the fuels.  A proposed solution is to turn the fuel back into a solid by freezing and applying pressure like at the bottom of the ocean where fuels like methane are in a solid and thus more stable state.

My concern in using this method of freezing and unfreezing is how much energy will be needed to convert a gas like methane into a solid.  The melting point of methane is about -297 F(162.5C) so an extremely cold environment would be need to convert and keep methane as a solid.  The other problem is that natural gas is another limited resource so putting lots of energy into collecting it is not a good long term energy strategy.

However, just like coal and oil, we will take natural gas as long as we can get it and so having a viable fuel transportation strategy is an important development.

Geothermal energy waste into lithium batteries

Most geothermal energy plants inject water deep into the ground where the earth’s heat energy turns it into steam used to generate electricity.

The wastewater from this process is full of elements that are not abundant on the surface and that includes lithium.  Without going too far into battery technology lithium batteries last four times as long as conventional ones and can deliver a lot of energy quickly.  The latter feature is extremely useful for electronics and hybrid cars.  The 150 MPG cars you hear about are made with lithium-ion batteries.

This is a great example of a change needed at the demand level.  Energizer makes them but  the cost makes them a rare purchase despite the advantages.  A synergistic relationship between battery makers and geothermal energy producers is very important. The educated consumer will buy them but needs to realize that you get what you pay for and 99 cent batteries last only hours.

How to feed the world

 

stop having so many kids

sorry to be callous but the planet is already way above capacity, if we were a restaurant the fire department would shut us down.

Better use and conservation of water, less petrol-fertilizers, genetic engineering, etc. are all good ideas but can come nowhere near solving the problem of global hunger.

Historically overpopulation has always seen a reaction from the forces of natural selection; Plagues

In fact, most of us carry genes that render us immune to the plagues our ancestors survived.

A long term stategy is important and it will be necessary to tell people they do not have the right to procreate if they can’t provide for the offspring.

If we don’t address the problem, mother nature may have to do it for us and I don’t think anyone would like a serious pandemic to solve the problem.

 

Pollution in the Charles River

pollution

I just read a book called Zodiac by Neal Stephanson and I liked it very much mostly because it takes place in Boston, the rivers and harbor which I know quite well.

It made me realize how different things are now in terms of pollution. In the eighties even the Charles and the Inner harbor were totally toxic, and I remember seeing the remnants.

44 Pleasant street in Watertown and behind all buildings to the west of there was poison. The small waterfall directly to the east had shopping cart, plastic bags, and all sorts of unidentifiable trash. I saw a large transistor and battery once.

Me and my friends played in the extensive muck  surrounding the beginning of the smooth Charles, past the tiny waterfall in Watertown.

Creepy trees growing out of slime

All still water a magic petroleum of rainbow colors

sink to the knees take many showers

But now like many places in Boston, IE Southie and the Combat Zone, the river has been gentrified.

Rich folks lead to clean rivers and corners and I suppose it’s not a bad thing, the Charles River in Watertown smells good and in the former combat zone there is nary a hooker or coke dealer to be seen.

The point is that at least in North America (excluding Mexico) the populous seems to have a proper outrage at being poisoned and so at least on the surface, plants can grow again.

Conflicting results

SeaLevelSatellite2000_12we21

I got some harsh feedback from the last post, particularly because of the idea that sea levels are not rising. The UN hired some scientists to research levels rising and when they found no positive results they were fired and replaced with scientists who found results more in line with the rest of the report.

don’t overestimate our knowledge of the global climate, particularly it’s influences and reactions, very little about the climate is intuitive

the earth is on a much larger time scale, we have existed for the smallest fraction of time and may not be as powerful as we think…I hope not.  Take a look at scenarios showing t what would happen if humans disappeared instantly.

The tides are mysterious, oddly enough in the 19th century we had the tides down to the minute but that’s a secret lost in the modern age.  Perhaps this is because it isn’t necessary  to sail on the tides anymore, I’ve had to do that when a motor broke and it’s quite a pain in the ass.

-we know more about the moon than the ocean

–this is not a reason to think emissions and pollution are not dangerous

at this point all sides of the political debate are throwing out a lot of BS…lots of spin on both sides.

find the studies by Dr. Nils-Axel Mörner, he’s an expert in the field despite the slander of fools.
