'A Congressional report quietly released last month suggests that bitcoin could be a threat to US monetary policy, and makes the case for continued central banking control.
The report, Bitcoin: Questions, Answers, and Analysis of Legal Issues, was published by the Congressional Research Service, which produces research reports for US policy makers. It argues for the benefits of a single, incumbent currency (the US dollar), for stability.'
Now in a true slashdot spirit there will not be an link directly to the report, instead I will provide a link to a link to the link of the report:

It is worth noting that in comparison with these three other recipients, Tesla had the smallest loan. Ford's loan was for $5.9 billion, Nissan's was for $1.4 billion, and Fisker's was for $529 million." Link to Original Source top

You will store ordinary files on the TDB as you would in a filesystem.
The question is: Which will give you the fastest read access of them?" top

What a wind turbine can't do is to produce electricity when the wind is not blowing. If we want that, we need to store the energy (somewhere) for later use. Batteries might be the first you think of but consider that we need to store energy for a number of wind turbine in the MWh class. The batteries themselves will not last as long with this type of charge and discharge that occurs here. We should be able to store the energy that can withstand this and having as little maintenance as possible.
If a wind turbine instead of producing electricity, produces compressed air we're having a much easier way of storing the energy in a large compressed air tank, directly at sea, near the wind turbines.
We have an pipeline for the compressed air into our land where we can use it for producing electricity, for example. We should also have an large storage tank (like in caverns) for the compressed air for later use as well.
What we have lost in effectiveness / efficiency is that we can now produce electricity even if the wind is not blowing! This will also help the network grid since we always produce the average of what the wind should blow in the area where the wind turbine is.
