Cold fusion is ignored because it is bogus science. We need to look elsewhere for our energy.
If we had unlimited energy, there would be some other scarce resource to fight about. We'd be desperate for certain chemicals instead, and people would fret that there needs to be a large government effort to supply us all with product-X for free.
Even if someone succeeds with cold fusion, oil will still be in great demand for at least 30 years because it is an excellent transportation fuel that holds a great deal of energy per liter of volume. Our transportation infrastructure is also designed around oil and it will take decades to convert this infrastructure over to an electricity-based infrastructure starting at the time that electricity could become extremely cheap. Nigeria doesn't have anything to worry about as far as selling it's oil at a good price during the next 30 years.
What happens when 6 billion persons on the planet can produce as much heat as they want without any economic check on consumption? You think we might have a global warming problem now?
Article from Nigeria... is it asking me to open a bank account?
From what I've read about cold fusion, it produces barely detectable temperature increases in whatever cooling fluid is used. To make electric power, we need high enough temperatures to make water into steam to turn a steam turbine generator. That's how nuclear power plants do it. If there's an actual fusion reaction going on in cold fusion, then why doesn't it produce gigantic amounts of heat as a by-product?
Science fiction authors have always talked about the use of limitless power obtained with very little effort. The "aether" was once assumed to be flowing with unlimited power, so all that was needed would be a way to "tap in" to it. In reality, There Ain't No Such Thing As A Free Lunch (TANSTAAFL).
