This is thermodynamics from a heat flow perspective, not an energy generation one.
Let's walk through this.
1. Water cannot be used to cool the plant because it is too warm. Warm water cannot carry enough heat away from the reactor. 2. The proposed solution is to cool the water so it can be used. 3. A giant heat pump will remove heat from the water and reject it to the air. This heat pump needs to carry more than the heat from the reactor. 4. This would require the construction of cooling towers, which evaporate water to carry the heat away. 5. The increased air temperature would also impose limits on the efficiency of this system. The hotter the air gets, the harder it gets to cool the reactor. Eventually you need to shut down the reactor because your cooling system cant keep up. Or you keep building more cooling towers. 6. As the cost of this rube goldberg solution increases, you re-discover why nuke plants are stationed near large sources of water - Rejecting heat to the air is inefficient.
They absolutely will. Even if the parents credit is crap, they know they can sign the kid up for all kinds of student loans. The college gets their money up front and the loan sharks get a non-dischargeable loan and can continue to collect even through a bankruptcy. It's the new indentured servitude.
Power plants need to reject heat into their environment in order to function. PWRs typically do this with a nearby river or cooling canals. Here's a few facts.
1. PWRs are about 35% efficient. This means that to generate 1.117GW, we need about 3.3GW of heat.
2. Thermodynamics says that you would need to radiate away this heat. If you do not radiate enough heat out of the system, you will lose your temperature gradient which is what does the work and turns the turbines.
3. Shedding energy via radiation is the least efficient way to do so.
4. For comparison, the Space Shuttle radiators were about 40m^2 and rejected about 70kW.
A quick back of the envelope calculation suggests that you would need a radiator 1.4km on a side to radiate enough heat.
It would be like the police asking you to see the registration and a copy of your drivers license before they return the car to you.
The car has a public key (VIN) number + registration number, and you have the private key (your identification). I doubt they just roll up to your house and hand you the keys without any sort of identity verification and paper trail.
i think the point is that if it is not at 2.45GHz, then the impacts on water (and flesh) will be dramatically reduced. Microwave is a pretty broad spectrum.
That is likely a security "feature" to prevent an attacker from using a fingerprint "spoofer" to gain access to the device. So they probably signed the hardware so only that specific sensor can work with that particular phone. Allowing the user to pair an unknown sensor would make the signing stuff pointless. If you force people to bring it into an apple store, maybe you can reduce demand for stolen and hacked phones since they wont work.
This is the key difference. The American ideal is that we are all "ordinary" people, including those in government. Making rules that divide society into "ordinary people" and some sort of aristocracy is not the American way. You can bet that the 1% in Europe have these firearms, albeit though their private security services.
The gun crowd in America does not want to give this up any more that we would accept controls on our speech (which Europeans also have more limits on). Lets face it, Europeans are much easier to manage because they are accustomed to authority from above managing their lives.
Feeding the world is a distribution problem, not a supply problem. We grow plenty of food for the world, but local conflicts do more to disrupt the distribution of this food than anything else.
This is why there is incentive to increase costs. More cost = more profit.
The government often asks for scads of reports and documentation to show that you are following their accounting, engineering, quality,... guidelines and rules. This needs to be delivered in their format, that they then give to auditors to pore over for years. Then there are "compliance" folks at the contractors whose job is to ensure that all reports are being done according to the contractual requirements. These contracts will often reference multiple contradictory government and industry standards, setting the stage for a number of people to research and resolve these conflicts. All of this extra work is "allowable" (since the government cannot ask you to perform work without compensation) and simply gets worked into the contract, inflating the cost (and improving the profit). If you have a high tolerance for bureaucratic quagmires, then government contracting can be very lucrative.
On the other hand, a commercial entity simply says "rocket costs 65 million dollars". The contract is a standard purchase order. Nothing more.
Even if you assume a burden of 100%, even $51.5k seems a bit high.
That is probably more like 10-15 employees employees with little more than a cubicle, computer, phone, and some basic benefits. $15 an hour ($30k per year). Maybe $35k-$45k per year.

But these were blueprints for legal weapons. It is legal for you to manufacture your own gun. You just can't sell them.

NRA protects the 2nd amendment. ACLU protects the rest, including the 4th. They are not just a "free speech" house.
You cannot be "secure in your person" if the police pick up random people because a computer told them to.

( 3.3 GW / 70 kW ) * 40m^2 = 1,885,714m^2
I think his point is that there is no such thing as "personal information". Treat any information you give to companies as "public".
OK. continuing the car analogy...

This has been the definition since the beginning of the tax codes. _You_ want to redefine it to your "any monetary gain = income" definition.
It seems pedantic, but when we talk apples, we need to make sure that everyone is talking about the same fruit.
And the rest of the money ends up in the hands of the business owners who take it out via dividends or capital gains. Just like they do now.
News Flash: The 1% do not have incomes to tax.

That might be their thought process anyway.

they don't let ordinary people have guns

Don't forget that Saddam tried to assassinate Bush Sr. Bush Jr. was responding to that.
He is pre-positioning it in the space garage, and will pick it up on the way to Mars. This way he will have something to drive.

Byproduct of what process? I am curious.

I'm sure Microsoft will talk about this use case in their next commercial.
