We just need to get fusion to work on such a scale that we convert enough hydrogen to helium to make it work.
Can't find how much energy we would need to produce to make enough helium to make a significant contribution, nor how hot this planet would become (each TWh produced must be radiated away). It may be so much energy that we'd be swimming in molten rock to get a decent amount of helium.
It doesn't really matter. One 400 kg (approx 800 pounds) man is enough for an elevator. 8 people of 50 kg (approx 100 pounds) is also enough. True that does mean the elevator doesn't know how many people are in the cart. But it does know if the cart is full.
In that case approx 99,999999% (slightly educated guess) of everything is nothing because atoms are mostly empty, molecules are mostly empty and molecules in gas are quite far away from each other. If something does not contain nothing then it's a black hole.
Doesn't vacuum wrapping extract moisture? That would mean it would go stale fast in a light vacuum. Bread is an open cell structure, so the moisture from the inside would be pulled out into the air by decompression.
In a freezer, usually at -18 C(approx 0 F) bread doesn't contract moisture. In a cooler, usually at +7 C (44 F) bread does go stale quite fast. The fact that a -18 C freezer is well below the freezing point of water causes most of the free water in the air to freeze to the bag. The water in the bread itself stays where it is. The crystallization does cause some trouble and that's definitely noticeable in the structure and the taste of the bread, but it's safe to eat.
Maybe because he doesn't like his bread to taste sour? There is nothing wrong with yeast, why use a substitute that influences the taste if you do not like said influence on the taste?
Why only a tiny volume %? Everything is chemicals. It's either a chemical or it doesn't exist in physical form. The nitrogen, oxygen, argon, carbon dioxide and trace gasses in the bubbles in the bread are chemicals.
And some vegetable oil (preferably olive), and if you want some poppy seed and some sesame seed for extra taste. Oh, and different kinds of flour. I use white and full wheat. There is much to optimize in a good bread, depending on taste and what your intestines want (some intestines need only a little fiber to work properly, some need a truckload).
I get my home baked bread to go for 5 days by increasing the amount of olive oil. A 500 gram bread should have about 1 teaspoon of olive oil IMHO, a "longer lasting bread" usually contains 4 or so.
Why would an elevator in this situation not come down from 5 to 4 if you want to go up? In "park" the software should select the closest elevator, in the absolute sense. The directional info from the buttons should only be used when the elevator is in use and it matters whether the elevator is going up or down. If, in that case, you call an elevator and don't get in this results in a useless extra delay for those in the elevator.
Doesn't an elevator know approximately how many people there are in it based on the weight of the cart? Plus it knows what the destinations of all people inside are. So if everyone in it wants to go to 3 or 0 and the elevator is full when it's on 27 then it shouldn't stop on 26-4, but it should just go on to 3 as fast as the limits allow so the elevator can get empty on 3 an 0 and go back up to pick new people up.
Remember, if the lights are optimized for a given speed V then it's also optimized for 0.5*V. That does have the slight disadvantage that everyone else on the road feels that you are a moron of you do this, and the accident risk will probably rise, but it works.
Not here. My salary is based on 4 hours per week. My employer doesn't control what I do during the other 128 hours, assuming it doesn't affect my performing on the clock in an extreme and negative way. Does 24/7 on the clock mean you can't enjoy a nice beer at home on a free Saturday night because that would mean you'd be drinking on the job? Having posed that: if your contract states that every invention you make (on or off the clock) is theirs that just means you didn't do the contract negotiations very well. Dunno if it'd hold up in court, I am not a lawyer, but I think it shouldn't.
You want the enemy to know you have nukes on the moon. That may prevent them from attacking in the first place. Most of the secrecy of the cold war was in - Finding out what the other had. That lets you know if you should worry. - Letting the other think you have more than you had. That makes them worry without you having to spend too much. If the Americans completed such a plan they would be damn sure the Russians would know it. At least a "mislaid document", probably a detonated nuke on the moon. "Let them know they wouldn't survive attacking us. That'll make them think twice."
If the Americans found a way to make the Russians believe they had nukes on the moon without bringing them the Americans would have done it. The same effect, less expense.
It is a fission reactor. The reactor speed is controllable with a boron carbide control rod. If it was just nuclear decay then it would not be controllable. The "old" RTG's were just powergenerators running off decay energy.
By the way: how did you think a normal fission reactor works? It's just enhanced and controlled nuclear decay that heats up a bunch of water to form steam. This steam dives a turbine that drives a generator: He presto, power! (for a more detailed explanation: just ask. I don't know the details of the reactions but others here do.) The main difference here is that they used Stirling engines and scaled it down big time. Sterling engines are probably used because they are incredibly reliable, despite being expensive and not very efficient. There is no way to fix a broken power supply in space, especially if you need to replace parts.
That'd fit nicely in the combination weapons list At about half there is a mace with 3 gun barrels that could be used as a holy water sprinkler (for the odd vampire you might meet).
Most discrete wire bonding processes are moving from gold to copper. Not due to contamination, but due to cost. Gold costs E700 per km of 23 mu wire, copper costs about 70. Copper is difficult to master though. If you are producing 1 billion SMD transistors a day then the few milimeters of gold wire in each transistor are starting to count.
Depends on the radiation you want. Americium is a readily available alpha radiation source and I probably have a couple of grams of it. Radium is also good as alpha source and easily available to but it's a bit spread out in normal houses. For gamma sources you may use gamma ray bursts, but since they are deep-space based I don't know whether anyone can claim to have them. I do not know where you'd get a beta ray source as a consumer.
Concrete has the slight problem that it requires massive amounts of water. Water is in short supply on the moon, all there is should be reserved for drinking and other essential stuff. This research is in the melting of moon rock with lasers (probably in a powder bed) to manufacture parts. It seems like it behaves approximately like silica, although I do not know whether that's a useful construction material. Perhaps a sidestep would be "welding" natural moon rocks together to obtain an airtight shell. Then no water is required to build the moon base. Assuming all the properties are similar to silica it may be possible to create quartz glass with it, allowing for windows. This lessens the cost of building a base (or maybe a city) on the moon. They are still astronomical, but this is a step in that direction.
The main difference is that the LHC does the collisions inside an extremely awesome detector. This detector can measure what the results are of the collision. A proton coming in at 0.9999999999999999999999951c carries the kinetic energy of a 60 mph baseball, but we can't really measure much more than that. We can't measure much about what happened when it hit our atmosphere, because our sensors were to far away. We can't even be sure it was a proton. It had aproximately 40,000,000 times the energy the LHC can impart on a particle, that we can measure.
In short: nature is awesome, but hard to measure. Lab tests are less awesome, but we can set them up so we can measure them.

In this case it seems to mean that you should shoot the receiving antenna's.

I didn't say it was much...
Sorry for the typo.

Due to the high level of sodium McDonalds food is never really safe to eat for me.

Element Zero (as in atomic number zero) is easy: neutron stars are made of them.
