The limit doesn't matter so much as striking it in the first place. Realistically, all of the mentioned investments are within the realm of reasonable thought. The presumption of a black swan is that it is completely outside the abilit

I don't think black swan is an appropriate title. This investing is more like when a small group of people split a large powerball jackpot; statistically unlikely, but not really fitting the definition of a black swan (at least as prop

Instead of worrying so much about a lawn, why not look into natural landscaping? http://en.wikipedia.org/wiki/Natural_landscaping The rough idea is to use local, endemic plants. They'll have a much higher toleranc

Oh yeah, I know what the company is, that's why I find it interesting. I was curious what you, personally, were working on.

What are you doing there? As an environmental scientist/economist who loves working with data-driven projects, that company always really intrigued me.

Thanks a bunch! I actually have a friend in Cornell's PhD economics program right now, and he's warned me about math (and he majored in math) and that Real Analysis in particular is crucial. That's what most concerns me, as I

Huh, some of your papers sound like ideas I sketched out in my commonplace book (particularly the ones on oil prices in the context of the larger economy), looks like I'm a few years behind. I guess my biggest concern is the viability

Hey, that's really neat. I'm doing a post-masters right now in energy economics and have been transitioning into using python for everything (from previously using Matlab or whatever was available), but I'm eyeing an economic

Universities and think tanks have internal review boards for a reason. The fact that Facebook can make use of its users' data in other (business-related) avenues does not excuse them from the most basic of research ethics. It did pass

Well, run-of-river installations actually don't have dams, and you can prevent most fish with just some mesh, so you're avoiding that impact entirely.

by cwal37 12y ago
Some last longer, some die quicker, it depends on the conditions and upkeep for a particular installation. I threw out 70 years off the top of my head to demonstrate that they tend to last a relatively long time. It also depends on what you

It's also a misconception to equate huge-reservoir hydro with all hydro. The Norwegians have incredibly high head, phenomenally efficient hydro in the mountains with minimal environmental impact. We have run of river hydroelectric in t

Not exactly. The 25th percentile's wealth was dropping even before the recession, which suggests some additional downward pressure, although I am not sure what that could be off the top of my head.
