Comment Re:Pit stops (Score 3, Interesting) 167

The battery is fully integrated into the vehicle and is part of the structure. It can't be easily removed. Not for lack of want, though. Swappable batteries are under development, but it will likely mean compromises in the chassis construction.

I'm more annoyed that there is a *minimum* pit time, meaning drivers have to wait and get penalized if they leave the pits too early.

Comment Re:Congress is a bunch of fucking retards (Score 5, Informative) 133

A really good telescope could as well be turned towards Earth to look at details on the surface.

No. For two reasons:

First, it's an IR telescope. The reason they're putting it in space is to get it away from Earth's atmosphere, which is opaque to the IR wavelengths it's designed to detect. Earth would look like a light bulb for all the IR it gives off and there is zero chance of seeing the surface.

Second, even if it could somehow be used to see through the opaque atmosphere, it couldn't make out anything. The James Webb telescope has a claimed resolution of 0.1 arc-seconds. It's going to be put into the Earth-Sun L2 Lagrangian point, about 1.5 million km from the Earth. At that distance and resolution, each pixel of the image would be ~730 meters square... just under half a mile. Useless for any kind of surveillance.

The same can be said for fossil fuel powered generators.

Except that, with the exception of natural gas, you have a lot of other combustion products to deal with. CO2 emissions from cement production are the result of baking the carbon out of the calcium carbonate, and it's relatively pure and therefore easier to deal with.

There are also only ~100 cement plants in the US, versus thousands of fossil power plants.

Where does this number come from? All the articles I have seen put that number at 5% of world CO2 emissions.

-The US produces about 5,500 million metric tons per year of CO2.
-Cement production releases about 1.25 tons CO2 per ton.
-The US produces about 68 million tons (2011) of cement per year.

68*1.25 = 87.5 million tons CO2 per year for cement production. That's 1.5% of the total.

How much does it absorb and what consequences?

33-57% of that which is released during production.

The 0.5 pounds of carbon dioxide equivalent per kilowatt-hour for hydro

Good job cherry picking the worst possible number instead of the one that actually applies. You even went out of your way to quote the article so carefully!

Small run-of-the-river plants emit between 0.01 and 0.03 pounds of carbon dioxide equivalent per kilowatt-hour. Life-cycle emissions from large-scale hydroelectric plants built in semi-arid regions are also modest: approximately 0.06 pounds of carbon dioxide equivalent per kilowatt-hour.

The part you quoted is for tropical zones and peatlands. So how much of the US is in a tropical climate zone, exactly? Hawaii and a little bit of Florida?

CO2 generation isn't an impossible challenge. Since the concrete production is centralized, it can be sequestered on site, and concrete naturally re-absorbs that carbon over the decades. Even if you don't address the immediate emissions, since concrete production is a mere 1% or so of total CO2 output by the US and the entire lifecycle emissions (including construction, operation and decommissioning) for hydro is a tenth that of natural gas, you're still coming out way ahead.

Comment Re:And now why this can not be done in the USofA (Score 1) 317

To US Energy Dept. estimated, in 2012, that there is ~12GW worth of power that could be tapped from existing, non-power-producing dams. That's handily 10% more hydro than what we've got now.

That same report estimates a potential for 65GW of new hydro power installations (85GW if you allow trampling of federal protected lands).

The reason hydro isn't talked about is because of uninformed people like you who think there's no additional capacity.

No. There's plenty of space to learn - and now there's recourse for abusing the freedom they've been given. The car doesn't shut off, the parents are required to remove driving privileges... if my kids want to drive my car, there are rules. I already told my son (months away from getting his license) that I will never buy him a car - I will by myself a car and let him use it as long as he's obeying the rules. He didn't complain... I don't owe him a car. It's a privilege. If he doesn't want to be monitored, he can pay for his own car and his own insurance... it's just that simple.

The context of my statement was presidential elections. Ideally, the president should matter very little. Unfortunately, after 240 years, the U.S. Constitution is essentially turned on it's head. In times of peace, the majority of governing is supposed to happen locally. If that still happened, we'd have much greater control over our local politics.

The other bad part about that is that by the time the primaries get to my state, the ones I liked have already been eliminated by the party establishment. I can vote in either primary (but not both) because we don't do party registration in my state, but by the time the primaries come around, anyone that would have made a significant difference is already eliminated.
