The amount of cancer caused by the sun each year worldwide is probably in the millions. Not very safe, but turning it off would be worse. Life is full of trade offs. Until coal burning plants are all gone the world should embrace nuclear po

I think that it is great that Jeff Bezos was able to grow his wealth by owning a good part of the company he started and now is in the position to spend about $1 billion a year on developing rockets and spacecraft.

Most cemeteries are open to the public so if they are in a city they are like parks and are very nice to have. I guess my comment is that the land a cemeteries takes up is not likely to be any more prime than any other land in a city.
906.
by njarboe 7y ago
When cemeteries where first created they were generally put on relatively unproductive hilly ground outside of the city or town. Not sure why you think they got all the best real estate?

Tournament chess could change this style by counting wins as more than twice a draw (say 1.5) but where a loss is still 0.

Southwest avoids most of these problems. Two free checked bags removes pressure from the overheads, no first class seats or extra legroom seats for extra money, no reserved seats (just a line up number system). Lots of direct flights and no

A list of tech needed to build such a craft[1]. I was interested in how they are thinking about getting a signal back to Earth from Alpha Centauri. It looks like they are hoping a 1W laser might be detectable from such a distance[2]. [1] ht

Nice to see some private LH2/LOX propulsion being developed, but I was hoping to see some pictures of some real hardware, not just simulations.

It's too bad this quote was published by Dan Baum in Harper's 22 years after Ehrlichman might have said it and after Ehrlichman was not alive to confirm. I would say the quotes around the text are not really appropriate for this m

The idea is that advertising often gets people to buy things that are bad for them (like maybe an energy drink?) that takes up resources to produce. Maybe people buying virtual digital items is better for society than buying a brand new Cor

Any adult in the US can invest in equities. The equities just have to be listed and approved. It is all the other type of equity investing (angle, VC, etc) that you are not allowed to do (and where all the growth is moving to) if you are no

Seems like France would love to have this technology to replace imported fuels, and the political problems that go with them, with fully-local nuclear-powered hydrocarbon production.

In the US, bus routes often run with zero passengers on the bus. Here is a Quora question and answer that states buses consumed 20% more energy than cars per passenger mile in 2009[1]. It references a US Department of transportation documen

Public transit doesn't come for free. Bus systems are sometimes worse than people in cars. I would suggest fixing the individual vehicle transportation system (congestion tolls + high gas tax would be a start) than forcing everyone to

Lots of cars around in 1871. I think grids are useful layouts for cities that don't have any motorists. Most of these gridded cities were designed before cars. Modern suburbia loves the cul-de-sac.
921.
by njarboe 8y ago
A gridded street system is also quite useful for inhabitants/businesses that want to go to an address without a map (or even with one). You can easliy go to a place you have never been to before. This is probably a highly undervalued p

No assumption, just a serious question. I agree no one is near that good yet. But it was a question that people should be thinking about. How good will be good enough to let the auto-vehicles operate on the roads?

Would an auto-car that crashed at a rate 1/10th of humans be a successful "full autonomous" vehicle? You could save 30000 lives a year in the US by deploying such vehicles and probably more due to knock-on effects. But that w

Cities are valuable in part for the high variety of interactions possible with so many different people. We should figure out how to do fast point-to-point individual transportation for cities. If you live in a city and meet someone interes

I think most people these days highly undervalue a system of roads that allows anyone to go to one place to another for the low cost of road construction/maintenance. Before paved roads and trucking, railroads basically charged monopol
