Conventional turbines only work up to 200 feet, but capturing a small fraction of the global wind energy at higher altitudes could be sufficient to supply the current energy needs of the globe.
The principal and only way to make an heirloom product is to design something that people will need not just this year, but for the next 50 or 100 years.
If you have to design something, choose things that we need as opposed to frivolous things that we might just want for a month or two for bragging rights.
We need a proportional quantitative understanding of energy use, for everyone.
Energy literacy means you can see the waste in disposing of a plastic bottle after you've drunk water from some place on the other side of the world.
If you write your own tools, you can sort of see new things, design new things.
In many respects, designing heirloom products means saying no to designing consumer crap that you know will not last very long.
