Is this the way the earth would look in spring time for all regions, or in the wet time for all reagions, or in the summer for all regions, or when there is the most photosynthesis for all regions? Remember it's summer south of the equater when it is winter north of the equator. In central brazil it's the rainy season but in the north east it's the dry season. So what does it mean?
That may be true but no one with purchase authority in the US Goverment can knowingly enter into an agreement like this. Doesn't matter if it might not be enforced. I've encountered analagous situations a couple of times and the vendor was told outright that the Goverment just would not agree, that they would change their terms or forget the sale.
The moon revolves with an approximate 28 day period so the collectors would have to be placed all around the moon so that some would be illuminated at all times. Then the power produced would need to be routed to the antennae on the side the moon that always faces the earth. Meanwhile the earth is spinning so any one spot will get some power for about 12 hours with the peak power delivered when the moon is near the local meridian. Since the received electricity cannot be stored and the time a local area receives the microwaves is only part of a day, conventional power plants will be required. They could work at reduced capacity when power from the moon is available and save fuel costs but would still have to recoup capital costs.
I doubt that you could plumb hydrogen to it from high pressure tanks because of safety concerns. I sure wouldn't want to work near a tank of hydrogen. In another post it was pointed out that the tanks are not just hollow containers and are quite expensive. Hence they would be returnable and refillable.
This looks like a reasonable solution to keep critical equipment running when the alternative is incredible numbers of lead acid batteries coupled with a generator placed, well, placed somewhere. Not for the home user.
I will wait for the fuel cells that are fueled by an alchol water mixture although a 1 kw unit might generate a little too much heat for an office.
Hmmm, I wonder how humid the room would get with a couple of them running.
You're right on target. Aircraft need to be maintained and inspected as well, a costly yearly operation for small aircraft. Attention must be paid to FAA advisories, logs need to be maintained, etc.
I think that more than 40,000 drivers and passengers are killed yearly in accidents with hundreds of thousands more injured. If this happened with aircraft the FAA would go berserk. So much for as safe as driving your car.
Many organizations require their pilots to take simulator training each year and that's costly, too.
IMHO flying aircraft will never be remotely like driving a car. Even with the glass cockpit, GPS with WAAS, etc. pilots need judgement and maturity and driving in Los Angeles for a while shows how this is lacking for many drivers.
My first thought is to make intelligence about the other player's dispositions and capabilities somewhat hard to come by but necessary to play well. I would make some of the intelligence sketchy and ambigouus. The players should have some options of disquising their infrastructure and hiding assets, too, so that some thought must go into tactics.
The Department of Defence helped bail out the Iridium system and is offering phones and service to all US Governmnet agencies with discounts and, if needed, encryption. It's not all but dead.
I just purchased a Motorola 9505 phone and was able to talk to my pilot yesterday from my cell phone while he was flying over the middle of the Pacific. He used it to keep in touch with the FAA controlers while out of radio contact.
IMHO Iridium gives the military access to a satellite system without having to put one up. I think that it will stay around.
The clock signal for civilian use is less precise than the military one and 'selective availability' degraded it in a kind of random but non-gaussian manner. Early on clever folks found that they could increase the accuracy in spite of that by placing a second receiver in a known location and either post processing the data or broadcasting the signal from the fixed location. This Differential GPS could have sub-cm accuracy. Other clever folks used other aspects of the signal such as phase difference to boost the accuracy. Others made receivers that could use the Russian and US GPS at the same time. In other words Selective Availability was cracked about 10 years ago but the Military refused to kill it. I think that it was for political reasons - not wanting to hear that a rogue missile directed against us used our own GPS for navigation , for instance.
It is possible to mount antennae on the wingtips, nose, and tail of an aircraft and use differential GPS to determine the attitude to a 1/100th of a degree or less. This can be combined with new, cheap, Inertial Navigation systems that allow you to point an IR camera from an aircraft and drape the image over a digital terrain model or map in real time.
I think that the Garmin site, http://www.garmin.com, claims less than a meter horizontal accuracy with WAAS for the Garmin V.

Right, that's what I heard as well. Hydrogen has less energy per volume than jet fuel so the tanks have to be bigger or stronger. Stronger means more weight and pressureized tanks might present more problems. Costs more, too, I think.
There won't be a polutiion problem as our atmosphere is about 79% nitrogen and that's where they will get it from anyway.
It costs more than gasoline or diesel (about the same as beer), requires a dewer (insulated container), evaporates, and can suffocate as it has no odor. It takes energy to produce it, too.

Well, it's cool anyway.

Hmmm, isn't the Forest Service part of USDA and don't they have some critical missions such as fighting forest fires?

Yeah, geeks are MUCH more specialized than nerds.

What's the efficiency compared to gasoline?
