About ndonnellan

I used to design big solar thermal power plants, then I worked on my first startup, autismlabs.com. Now I'm at a major EMR company having lots of fun and trying to fix healthcare. For serious!

email me at ndonnellan@ that common email provider's domain. Hint: google for it.

    I was going to chime in to second this. In a former life I worked on power towers and we had designs for air receivers that would potentially work really well with this type of sys…

    Portland, OR (NW Oregon in general) also has a lot of planted Giant Sequoias! So it may not be strictly true that they are super picky. I imagine as climate warms, the PNW will bec…

    I think the key paragraph is buried: "Though water itself does not absorb much light, and neither does the hydrogel material itself, when the two combine they become strong absorbe…

    I wonder why Wired didn't provide any hyperlinks despite mentioning the site (italicized) several times. Seems like common internet courtesy. Perhaps just a direct-from-print copy.…

    Thanks for the reply! Sorry I don't have any great sources off the top of my head. It makes sense that you'd want to restrict the scope of the article to make it more understandabl…

    I like the structure of the article and it's a good procedure for evaluation compensation, but my nitpick would be it could be more helpful if it included more realistic numbers. D…

    You mean like Optimizely? I thought most startups these days had absurd adjectiverbnoun names.

    If you're looking to cut down on solar heating, steel roofs or even lighter colored or painted roofs would be a far more cost effective option.

    I think the legal definition of NA beer is maximum of 0.5%. I may be misremembering, but I think Athletic Brewing mentioned their beers are closer to 0.2 -> 0.3% on average. But ev…

    Yes, I think your reading is correct. The article makes claims the paper does not about comparing Vertical vs. Horizontal wind turbines.

    Caution though: this can lead to blind spots. I witnessed a critical bug become exacerbated by the first fix because the developer and reviewer had essentially co-wrote the solutio…

    Summer months in most of the southern US are extremely hot (in Austin, 4-5 months of the year could have temps above 100F), so for example here is CA in August (see graph in articl…

    I doubt the rotation speed is 1/s, that would imply pi*220m/s at the tips or 2488 km/hour! Based on animations, it looks more like 1 rotation per 20 or 30 seconds. 20-30kWh seems v…
