How do you provide electricity to power it? Nuclear. And what approach will that require? Basically some form of a thermo system. That means that we have to dump the waste heat, which in space can ONLY be radiated away. Considering the large and HEAVY infrastructure required for radiators, it would not work.
OTH, a nerva WILL work. And it has the advantage that you add a small power plant to it that will provide power just for the spacecraft.
I think that you will find that many in the world refer to EU as being =~ to Europe. IOW, the build up of Europe from an economic pov took place because of the expansion around the world. That is most true of UK.
Look, this is the first time that all partners have had crafts up there. Historically, only 2 nations have had crafts up there at the same time. But when you have all participants up there, then the write gets excited. Personally, I would argue that you are making a mountain out of a molehill.
I used to be a big fan of VASIMR. That is until you start to look how to generate electricity for it. Solar will not cut it, except for a real slow cargo system. For humans, we need to move fast. It will require a nuke reactor. Assume that we do not have DIRECT generation of fusion to electrons developed in the next 10 years. That means that we are left with fission thermal system. Not a problem. Right?
WRONG. The nuke generates the heat which can create steam, and drive a turbine. BUT, you have to dump the heat to cool the steam (or what ever your working fluid is, probably ammonia). On earth, we just dump to the environment. We have matter all around us to accept that heat. BUT in space, you do not have it. Instead, you have to radiate it away. That would take loads of radiators. And that will take a structure to support it. That structure will be HEAVY. All of that means that ION will NOT WORK FOR HUMAN TRANSPORT
OTH, a simple nuke engine WILL WORK. A reactor is used to heat nothing by hydrogen. This is what nerva is about. We need to restart that up all over again. In addition, we need to restart breeder reactors in the west esp. in America. Amazingly, we have loads of 'waste', that is ideal for this. Heck, if we are so afraid of this, we could build a small breeder for use in space. Put it at L0, and then use that to re-fuel a ferry engine.
Zubrin lives up the road from me. I can tell you that Zubrin would MUCH rather that elon did not have the book. The reason is that Zubrin worked at L-Mart and will continue to push that nightmare Constellation. In fact, I thought it interesting that Zubrin had little to say when Musk was talking about doing a Merlin 2/Falcon XX, yet, threw a fit when the MASSIVELY EXPENSIVE AND 30 years to develop Ares V was cancelled.
One of the bigger reasons for the dislike is that Zubrin wants a 2 way mission. Musk is already pushing for ONE WAY MISSIONS, which zubrin hates. Yet, the high costs of return trips combined with the damage due to long trips, pretty much guarantees that we must make these one-way.
Best damn post going. Sad, but so true. For the last 30 years, our nation has been buried by politicians that speak of a balanced budget while at the same time running up monster deficits during good economic times. We have idiots blaming Obama, but those same idiots voted for reagan and W. reagan/W were responsible for causing nothing but chaos in the world, while destroying America's abilities to compete and further itself.
Actually, it is not the broken window fallacy. History has shown over and over that expansion into new areas returns money. BIG money. THat is how EU became large from an economic POV. We will certainly find new things on Mars that we never expected. Finally, by sending man out there, we preserve our species. The fact is, that we do not know why species has been wiped out over and over on Earth. But Mars (AND expansion into the oceans) should be seen as an attempt to preserve ourselves.
should be nuclear. Seriously. We need to develop a small nuclear ferry for sending goods between earth and mars. Building a prototype for moving small samples and cargo around would be worth it.
Does anybody know of a good replacement for the typical 25/40 W mirror bulbs?
I have not found anything other than CFL and I am not putting that in an easy to hit area..
Their problem is that they are not paying attention to all the dirty pool that MS is up to. They need to do the same back-behind-the-scence kind of work that MS does against them.
Qwest (now some other company) has horrible service. HOWEVER, it is a landline, in which you have a connection that is pretty solid IFF everything is buried. Perhaps most importantly, is that the RBOCs will not overallocate the calls on the backbones. Finally, they prioritize calls over net. This contrasts with Cable esp. Comcast. During an large crisis, you will NOT get through with either comcast, most cables, and absolutely NONE of the wireless. So, your best bet is to have cable for the network, an RBOC for a cheap cheap landline (as in skip the perks), and of course one of the wireless.
w/practically unlimited geothermal energy
You have to be kidding. There are MANY more places on this planet with loads more geo-thermal. However, for the number of ppl on the island, it is a lot.
With that said, my bet is that unless EU starts putting in pipes that can deal with H2, then an H2 project will NEVER go anywhere.
And by close to the surface, we are talking about.1% of the earth. IOW, out of just about everything that we have done, this is the least likely to result in damage due to the MASSIVE amount of it. The only thing with more energy, is the sun.
Can this be pulled up and used to form bricks? And how hard is Igneous Rock? The magma COULD be poured into shapes. For example, comes from home wool insulation comes from basalt. Or how about bricks?
Then of course, the magma comes up hot enough to melt iron. This could give a nice way to create a smelter for iron, or even for concrete.
YellowStone is showing signs of eruption. Now, would be a great time to consider the idea of taking the pressure off by actually using the magma to run a LARGE power plant.
Actually, even I have to admit, that I would fear if we got another idiot like W in here, though that is hard to believe. Sadly, Trump, Palin, etc are such idiots.
Yeah. Right.
Here is a clue. When all other moneys are in play against the dollar, and the Yuan does not move for several years, then I think that it is safe to assume that it is fixed against the dollar.
China has not been honoring ANY of their treaties. They have their money fixed to the dollar. They have trade barriers in place. They subsidize and dump on the market. They steal IP all over. Per their treaty with Japan, they are required to have scrubbers on all of their power plants. W SHOULD have taken care fo this last decade, but did not. So, now, America decides to address just a little bit of the issues, and you think that China will start a nuke war over it and that America is to blame?
I love that stuff with Chavez. We WILL sieze the refinery and other equipment to compensate for the stolen platforms. But what is funny about that, is that Chavez can only sell that oil to America at this time. This man really knows how to screw himself.

Oh, I was not aware that Israel has dropped bombs on any civilian-only sites. Do you have proof of that?

I think that you miss the point. What you speak of, is why we have Wireless, landline via RBOC and net over cable. Redundancy is a good thing.
Their problem is that they are not paying attention to all the dirty pool that MS is up to. They need to do the same back-behind-the-scence kind of work that MS does against them.

Wow. I'll bet your shrink gets tired of your neurosis.
You need to grow some balls.
I missed that entirely. Thanx.
Have to say that Comcast absolutely sux, since we do not get science with them. I am looking to change out to Dish and pick that up.
Seriously, SyFy has been turned into a joke by the ppl that run it now.
