Hyrpoxia, Eutrophication, Carbon and Power

So we live in a world with all sorts of problems.  To me these problems are temporary until we can figure out how to solve them (and probably create different problems for ourselves in the process.)

So here is a problem chain:

1. We want cheap, easy, reliable food source.
2. Therefore, we use fertilizers to make food production more efficient.
3. These fertilizers eventually end up in rivers.
4. The fertilizer causes Eutrophication, lots of algae, phytoplankton or cyanobacteria growth which hamper other plant/animal growth
5. The algae, phytoplankton or cyanobacteria die and are then eaten by bacteria which use up all the oxygen.
6. This creates hypoxia, or a dead spot in which most marine life cannot live.

So, here is what I think could be a solution.

• Gather nitrogen rich/algal rich waters and confine them.
• Allow  more algae to grow.
• Harvest the algae
• Bacteria eat the algae, producing natural gas.
• Clean water returns back to the river.

Ideally the elevation head on the water would power most of the plant, and the natural gas production could pay for it.

Captcha's

Who thinks capchas are annoying?

I think instead of these we should employ less annoying means of stopping spam.  Such as pripple could make an account worth an anti spam service that would verify too other sites that you are a human.  The site could collect data such as time of day, platform, browser, ip address, location and a rough picture of your behavior to determine if you are likely to be a spammer.  Only if this data indicates a high risk of spammer would it require a test.  Tests could be fun, such as identifying objects in not copyrighted art and photos or playing a little game or reading handwriting from old documents to digitize census records and so on.

Stitching Pictures

Have you ever taken a picture with another person, or better yet a group of people?  Have you ever been somewhere and noticed that everyone is taking pictures?  Unfortunately even when you take the same portrait with a dozen cameras, all you end up with is a dozen incomplete pictures.  Some were too close, others too far, some too bright others too dark or grainy, some were a little blurry, some were framed too wide, others cut off someones arm, or head, some had one thing in focus, others something else.  Even with a single camera, there are these variations as a handful of pictures are taken.  In one someone was squinting in another someone else sneezed.

What if you could put together all of those pictures?  All of them are out there digitally somewhere.  The first step would be to collect all of the pictures of the same scene in one place.  The next step is obviously the hard part, -stitch them all together to make a 3d or quasi 3d image with higher resolution, better color, better lighting, everyone eyes open.  It's completely possible with today's technology.  ...It's just a matter of time until someone does it.  Sorry it won't be me, I'm busy.
