Comment Re:To impress me, try cross-city drives instead. (Score 1) 132

Yeah, I don't get all the "fully autonomous cars will be here soon" posts. Sure, I can see cars that can handle themselves on the freeway, given clear weather and no construction. We're almost there anyway with the adaptive cruise control and lane keeping systems on cars you can buy today. But we're a long way from cars that can handle construction zones, two lane highways and rural roads, poorly maintained roads, gravel roads, bad weather, and the like. If I was a professional driver I wouldn't be worried quite yet. Once you can give an autonomous vehicle any random destination in the US and it can get there on its own without any human assistance then maybe they should be worried.

The key with Venus is to not land, but build could cities about 50km up. At that altitude, you have an atmospheric pressure of about 1 atm, temperatures are a bit above freezing, you still have the Earth-like gravity, and due to the atmosphere being mostly CO2 (a heavy gas), a balloon filled with breathable air will float. You've also got plenty of solar energy (during the day, at least). It's about as close as earth-like as you're going to get without actually being on Earth. On the downside, you have the 200 MPH+ winds to deal with, the lack of a strong magnetic field, as well as the long day/night cycle.

Comment Re:It is not solar and wind... It is natural gas (Score 2) 283

Because of the fracking boom, we've got so much natural gas that we don't know what to do with it all, causing the price to crash, and given that you can convert coal plants to natural gas without too much difficulty that's what a lot of utilities have been doing.
