the answer my friend, is blowing in the wind

Driving back from Indianapolis to Chicago, we went past this brand spinning new wind farm right next to I65. It was still under construction just a couple months ago. This is the closest I've seen wind turbines next to a freeway. I have a closer photo I'll post later. Anyway, once they figure out the storage issue to make it more dispatchable, and work out the mechanical kinks with gear failure, we will see wind grow. Any new technology goes through learning curve. Back when, people were getting killed by steam boilers blowing up all the time on steamships till they set up design codes and improved their understanding of the design limitations.

Hard to beat free fuel, so wind will be part of the mix for a while.

Biomass burial

So we raked the leaves this weekend. Small yard, several big trees, lots of raking. Because of the artificial construct of the suburban yard, we need to move the leaves so they don't choke out the grass. I doubt if the "normal" vegetation balance between tress and grass would look anything like this if we left them alone. I don't want to use chemicals on the yard, but I wonder what is happening to the soil since we ship out hundreds of pounds of leaves each year, and they must be taking minerals with them.
