While doing Space Power Sat research, I often come across all sorts of crazy energy, and enviornmental concepts.  Most of the time they’re small potatoes compared to SPS/SBPS, but this one is a good idea.

If we’re going to solve our worlds problems we need big ideas like this, but ultimately the failure to inspire others to follow through on any of these dreams will result in all those chicken littles being at least partially right.

This energy system matches up pretty good against SPS. However, I like to think that if we’re building giant towers in deserts. It wouldn’t be hard to put receivers on top of them, much like some advocate building SPS recievers on OTEC plants. Both combo technologies would produce massive amounts of energy and fresh water. However, OTEC is the only concept on the table that has heavy carbon sequestration as a side effect. Bahhh, getting to much into the details.

If you’re into alternative energy OTEC, and Space Power Sats are some things that you need to know about. This concept might seem off the beaten path, but it’s a testimate to the fact that there are solutions to the worlds problems other than windmills and solar panels. I’m going to add this one to my stack of world changing concepts.
