Comment Re:oh please. I'm tired of this "diversity" bullsh (Score 2) 493

Weirdly enough, women were quite well represented in technology before the 80s. Clearly there was an interest - so what's changed?

What changed was the definition of what a technology job is. Before the 80's, technology jobs included things like typists, calculators, vacuum tube changers, telephone operators, etc. These were relatively low skill repetitive jobs that were well suited to women in the workplace which didn't require higher education, physical ability, or advanced trade skills.

Comment Re:And this is why burning Uranium is stupid... (Score 1) 282

This makes about as much sense as worrying about deorbiting Jupiter with all the gravitational slingshots we do around it. The amount of uranium we consume is extremely extremely tiny. For example, we could power 100% of the entire world's energy for 10,000 years using only the depleted uranium sitting around unused in barrels at enrichment plants. We might be making very inefficient use of it now, but there's nothing to stop us from eventually digging up spent fuel and reprocessing it, for instance.

Comment Re:Nuclear is a dead end (Score 1) 176

In 75 years all of the low hanging fruit reserves will be mined out... according to current estimates that leaves 125 years of increasingly harder to get (i.e. more expensive) ore.

Then what? I guess develop the clean energy that we should be working on now.

No. Using proven fast reactor technology, we could supply 100% of the world's energy needs for 10,000 years just using the depleted uranium sitting unused in storage barrels at enrichment plants. Not to mention the huge amounts of raw uranium ore, tailings, reserves in localities that have previously banned mining, and seawater extraction. Nuclear fuel availability is purely a political and social problem, not technical.

It also takes pressure off nuclear power companies to invest in reclamation and reprocessing technologies and frees them to simply consume fresh nuclear fissile materials without concern for their total lifespan.

While most of your post I would disagree with, this part is especially wrong. The reason why power companies do not invest in reprocessing and consume fresh fissile material is because by federal law bans it. Remember Jimmy Carter's Non-proliferation deal? Yeah.

Nuclear waste disposal isn't an engineering problem

The folks in Japan working the #4 unit of the Fukushima Daiichi plant would like to have a word with you about this. It was shut-down and defuelled before the tsunami struck, and despite this its spent fuel pool's contents blew the building apart.

You are misinformed. While the stability of the fuel pools was unknown and a concern at the time of the disaster, it was later determined that they were in fact not leaking, damaged, or in danger. No fuel in storage was compromised. The damage to Unit 4 was caused by the hydrogen explosion of Unit 2.

Comment Car Analogy (Score 1, Insightful) 113

A particular high performance car has a premium 8 cylinder engine and 32 valves at 400 hp. They also sell a non-premium version which is also 8 cylinders but only 30 valves and makes 350 hp but is a lot cheaper. The difference is that one cylinder is missing two valves which lowers its maximum power compared to the premium version. The engine's computer correctly controls the engine to compensate for the one weird cylinder, but someone in the marketing department sold the car as having 32 valves when it only had 30. The 350 hp figure is accurate, but some people complain because if they reprogram the engine control chip to force the one 2-valve cylinder to run at the same conditions as the other 4-valve cylinders, the car only makes 300 hp. But in all normal circumstances the car performs as advertised, only it was initially sold with incorrect details as to how the engine was put together to make it nearly as fast for much cheaper than the premium version.

Compare that to Saladin who showed mercy and the let the Crusaders go (for the most part).

Sounds like you are taking the Hollywood version of events a bit too seriously. The only Crusaders that Saladin let go were the wealthy nobles who could afford to pay ransom. Everyone else was screwed.

Comment Re:Inconsistent fuel? (Score 1) 289

The Endurance itself was large and heavy and full of fuel, requiring a large rocket to get to orbit.

The Ranger was a small, lightweight spaceplane which probably used something like a SABRE engine.

Here is a delta-V map of the solar system. According to it, you would need 6300 m/s delta-V to return to Earth from Mars. Which is about 2/3 the delta-V required to get to Earth orbit.

The reason why no one switches energy providers whom put their cables underground because if such a utility did exist, its electric prices would be much higher and almost everyone would chose the cheaper, slightly less reliable option and drive them out of business. The problem isn't capitalism. The problem is people like low prices and our current system is good enough not to warrant voluntarily paying more.

Comment Re: Market forces don't work on essential utilitie (Score 1) 516

On the contrary, market forces work fine. The problem is simply a case of the leaky roof problem. You can't fix the roof it when it's raining, and when it's not raining there is no need to fix it because it isn't raining. When people's lights are on and working it's hard to convince them to voluntarily pay more to upgrade transmission systems.

Why not just add a small camera attachment to the gun (i.e. on a picatinny rail where flashlights are commonly mounted) and have it automatically activate whenever the gun is held? Seems simple, cost effective, and would show exactly when and what is being aimed at and what was happening.
