Like everything there is a saturation point in solar energy: exposed area. Anyway, cheap energy will never be a cure for poverty and malnutrition. People get richer will simply consume more and people not dying will increase population. After some time, everything will stabilize and in proportion the number of rich and poor will stay the same.
The only viable option is to consume less and increase efficiency to become less dependent on energy (any source). Transporting goods in all cases is the worst thing to do.
It's fine that you understand it correctly, but many people don't get it the correct way so I had to explain the basics anyway. This is a public forum so you will always get generic imprecise answers. I worked in an evolutionary research lab for two so all this is clear for me, but I am not really at explaining it.
You are right the queen genome encodes all the genes, but in each individual only a specific set of genes are activated. Which set is activated depends on growth conditions (feeding, temperature, humidity, etc).
The best way to view it, as someone else said, is to consider the whole colony as one organism and each member as one cell. To transpose your example of storage-ant, humans have fat cells. Those are unable to do anything else. The genes which allow them to store fat are useful for the organism but they would detrimental to reproductive cells. So reproductive cells don't activate them, but they still carry the genes.
Also, don't forget it is not unique to insects. Wolves organization is similar. At one time, only two individual can reproduce. The reproductive capacity of other members is inhibited (by stress). When food is limited, this type of organization can benefit the specie but evolution will be slower, because average generation time will be higher.
Offtopic, but something to consider. It's not the organism who want to reproduce, it's the genes. DNA is selfish.
I think you understand the steps in reverse order.
1. a mutation happen randomly in sperm or egg. 2. a new queen is born from this mutated reproductive cell. 3. mutation is positive (e.g. the slave from this queen are more efficient) 4. the queen give birth to more new queen than one with less efficient slaves
Let's look at it in another way. Infertile workers are like our cells. You can have one white cells which is resistant to HIV, but this mutation won't be passed to your offspring. But maybe one of your sperm (the one) will have the mutation which give resistance to HIV. So your son will be resistant to HIV. He will have more chance of surviving and also to reproduce.
Evolution is a very slow process. Mutations happen relatively frequently. Positive mutations are rare. It's also rare that it is present in germinal cells and rare that an offspring is produced from it. The advantage gained is not always enough to allow it to be propagated. it's very rare that all the conditions are met. That's why it's so slow process.
Bacteria are a lot more efficient at propagating mutations than us.
And concerning bees, the workers have the same genome as the queen but some genes are only activated by the royal jelly given only to future queens.
the files are splited, encrypted and stored on multiple node on the network. each person installing freenet is running a node and is storing files from other person on his hard disk. You can't know what you are storing and the authorities don't know neither. All the traffic is also encrypted. each node know of some other nodes and ask them if they have a file and if they don't they ask their neighbor too. Then the content is propagated back to the original requester and no node know who it was exactly.
It's often slow but very secure and hard to control or stop.
If you are looking to just another filesharing network like edonkey/kazaa/gnutella, freenet is not for you.
Freenet is different.
For content to be available on freenet someone must upload it to the network. The advantage is that once something is on the network nobody can delete it and it don't matter if the original owner is online or not, but "publisher have to make an effort if they want content to be available. Freenet is not really like other P2P filesharing, it's more like a distributed anonymous storage.
Each freenet client choose a port randomly during its installation.
so restrictive caps are not a problem with freenet.
the problem is probably the searchability.
for content to be available on freenet someone must upload it to the network. Then someone who want to download it must know the "address".
but one advantage is that once something is on the network nobody can delete it and it don't matter if the original owner is online or not.

Is it just my imagination or I saw ads from Sun before this story was posted?
If ads are ahead of news, the subscription is pointless.
If I remember correctly there is already an option in Evolution to automatically load images when the message is from someone in your contact list.
Not perfect, but a step in the right direction.
I prefer English.

And goats could be also used as women replacement.
Very nice idea.
Trillian? I don't think messenging software need (or should be permited) to execute code they're not supposed to.
This should be reported to the developpers and corrected in future version.
there is no central server

It's not implementable because most gnutella client will refuse direct connection if they already have their maximum number of connection.
