First off no, nature doesn't thrive off solar power alone. At the very least hydrothermal vents provide energy to most aquatic life past the thermocline. I'd also like to point out that the sun produces more radioactivity then anything like

There are large quantities of fissable materials which are not uranium. For example take thorium, which is roughly as common as lead.

That's a non sequitur. Look up the first nuclear pile experiments and you'll find out just how primitive you can be and still produce a functioning nuclear reactor.

That makes no sense. You create some random key K. You encrypt k using the public key of the recipient, ie. e(k). You encrypt the message using K. You send both of those to the recipient. A cyphertext only attack can recover K from your mes

The problem is that we have fewer IPV4 addresses then we have consumers who wish to consume IPv4 content. Take our current situation: We still have large swaths of china and india without Internet connectivity, yet we are basically entirel

Interesting, do you have any links as to how they work/how they are constructed/etc?

On the other hand, you can always use thorium deposits, use nuclear waste from other nations as fuel, pull uranium from seawater, etc.

Yeah, there are a few different types. One sits on shore and uses wave power to compress air, which then runs turbines. This is probably the most efficient method i've seen. There are a few others though, like the buoy method, etc. Solar is

* We currently have massive political pressures blocking the production of nuclear reactors. There is no problem in building it, the problem is in the politics.

Why don't you use the standard openssl RSA encryption function to encrypt the entire file, rather then encrypt a plaintext passphrase? I don't know of an implementation that uses RSA encryption that doesn't use RSA to encrypt a (heavily pad

Starting a rebuttal with the word "wrong" seems rather counter-productive. If you have a reasonable point that disproves mine, then anybody reading it would notice this and as such the "wrong" is not required. If on the other hand, your poi

Eh. Fossil fuels will destroy the biosphere. They regularly and fairly brutally destroy rather large swaths of it (see nigeria/etc.). Hydroelectric plants destroy parts of the biosphere. They massively damage aquatic life and fish species a

Nuclear power reactors can be produced without any real proliferation risk, see for example thorium reactors. Similarly the thorium fuel cycle is a lot clearer, ie. assuming that you can recycle actinide wastes, there is very little radioac

Stating that air travel is safer then cars doesn't mean that I wish myself to be strapped upon an early glider and hurled off a cliff. The fact that one such glider still exists and is apparently in use has no bearing to the current state o

Strangely enough it takes very little money, nor energy to produce nuclear power. It's very simple at its core. Have a look at the first research reactors and you'll find that you need basically no technology to produce reactors that produc

It's interesting, but from what i've seen of it (albiet not all that much), it has two major issues. * It has a low power density, hence requiring large arrays of collectors/etc. this makes it costly to build at scale. * It generally either

There are plenty of other designs, most of which get built as test plants, work nicely then never get built again due to political pressure to stick to "safe" designs.

by asharp 16y ago
I would have a look at pebble bed reactors, molten salt reactors and heavy water moderated reactors. long story short, the designs exist, we just can't seem to get rid of the old ones that are currently built and we can't seem to get the ne

As a quick bit of thought. Lets say that you need to mine, say 2,715,384x the amount of coal to produce the same amount of energy as you would uranium. (From https://secure.wikimedia.org/wikipedia/en/wiki/Energy_densit... ). Now if mining

We just need to build newer reactors. The problem isn't that we don't have designs that can deal with these sorts of problems. The problem is that we don't have the political strength of will to decommission the older, unsafe plants and rep

fusion development hasn't been stopped, especially not for fear of proliferation. Do you have any information about this subject that I do not? Also, the major problem with putting solar power plants in deserts is that you lose most of your

What would you suggest? Keeping in mind that basically all renewable sources sans hydroelectric can't be used to provide baseload power and hydroelectric power both has very few potential locations (most of which are in use) and has the nas

If memory serves, the problem is that it is politically impossible to create some area to place the waste fuel. ie. it would be much safer to move the spent fuel out of the reactor, however there is nowhere for it to go to.

As per point #3, remember that you amortize the cost of r&d along some payback period. As such it does effect your margins. I do agree with your point though. Decreasing development time is the means to the end of making more money out

I think point 7 needs a slight bit of expansion. -> Don't allow anything sensitive to be accessed from the outside world. Creating a vpn takes seconds and provides a very strong wall between everybody who isn't you and your vulnerable s

Interesting, and very close to the implementation of Etags. On the upside, it means that files that haven't been changed won't ever be rerequested without needing a round trip to the remote server. On the downside, you clutter up caches wit

Well, no. Think about it this way: Speed is the number of requests/second a single server can process. Scalability is the amount of computing power you lose when splitting a job amongst multiple machines. Intuitively you can think of it li

From what I remember, the problem isn't producing something that parses (for the emitter), the problem is producing something that could still be considered human readable and/or not horribly ugly.
