I admit, I don’t know how dangerous a neurotoxin the Decaborane used as fuel is. Is it up there with military nerve gas? Or is it very mild, taking a large dose and long time to cause a problem. One thing I’m sure of, propane is not a neurotoxin. If it is a very dangerous material, then the reason for security is obvious.

Radiation. The general public is very uncomfortable about it. That is a simple fact. It may not be based in fact, but the fear is, never the less, a political reality. So, no, it will that a long time (my opinion is >20 years) before the public will accept them near urban areas.

I would point out that your example, windmills, tend to be installed in “wind farms”. Land acquisition, transmission access and ease of maintenance are all reasons for this. So, your example has aspects that support my point. Certainly, some wind power units are singletons. Mostly as one will support the load the owner wants to supply.

I’ve never said that there would be no distributed installations. And I would agree that more distributed use will grow in time. But there are also reasons to centralize things. These factors will, in my opinion, for reasons I’ve stated, lead to initial deployment being more centralized, repowering existing plants and installation of new FF “nodes” at locations were transmission, land use and other factors make it a good choice. Heavy industry, remote loads, ships, etc. will also be early locations. After the first period of deployment, smaller nodes, nearer load, will likely develop.

I’ve not seen anyone give a reason, other the philosophic, why extreme distribution, one for this building, one for that neighborhood, etc. has enough advantage in transmission cost to overcome the dis-advantage in installation and operations cost it would entail. But, as no one yet has hard numbers for these things, it will remain strictly opinion until Focus Fusion is actually deployed.

But, I’ve never disagreed that the economic, environmental and supply availability advantages of FF would drive it to very, very rapid deployment. I’ve only disagreed on the method of that deployment.
