Carbon Capture and Storage (is a bad idea)

For a few years now I have been hearing about Carbon Capture and Storage.  I always thought I should read up on it to see what its all about.  I figured (incorrectly) that it was about planting lots of trees.

Carbon capture is about fitting a device to a power station and extracting the carbon and then pumping that carbon into the empty spaces left by mining the gas and oil.

As illistrated.  Now clearly there are a few issues there:

Firstly its not the trees I was expecting,
Secondly it only on power stations that have been converted,
Thirdly the medium term cost (when the station is decommissioned the equipment is useless),

My MP asked what I would consider to be a stupid question:

"What assessment has my right hon. Friend made of the overall job creation potential of CCS over the next five to 10 years? What will he do to ensure that such jobs are created right across the regions, and not just in the areas local to the plants?"

How can a scheme to fit a filter to a power station c…

Preauthentication and email

Ok, a significant part of the Internet is devoted to spam/junk emails.  Never has a day gone by in the last 10 years where I have not had a single spam email and that is with the best filtering you can get.

My brother reported to me yesterday that my dads business deals with 20,000 spam attempts per day. Perhaps 3 to 5 get though.  Which statistically is fine but for a user its annoying in the first place.

At the beginning of the decade their was a flirtation with pre authenticating people with whitelists of known people.  This died out as people hated having to email to say yes this is valid and it broke mailing lists.

Now I prefer instant messages because of that pre-authentication is built into the protocol.

For email to survive it needs to evolve.  Claims that changes that break existing functionality need to be pushed down.  You cannot make an omelet without breaking some eggs.

Email servers need to store whitelists, they need to get the whitelists from their users.  The same sys…

Defaulting on your mortgage

The greedy goblin (which is a blog mainly about World of Warcraft) also gives out economics advice.  Today's was indeed special:

Basically if you owe more than your house is worth, stop paying the mortgage and walk away.

Which on the surface looks socially irresponsible because it would lead to wider poverty and we are told as a species we need to work together...

However after reading the whole thing it lead me to think that those that did act irresponsible were the bankers and they are the ones that are living the high life...hummmmm

The article makes a point that if you were in negative equity of 100k and you pay that off, you are feeding the bankers.  If you walk away you save yourself the cost of 100k loan.

I personally am not in negative equity so cannot pull this trick off but it did get me thinking about moral obligations and is our sense of duty wrong?
