Works wonders for the wind industry.

"A light bulb made from graphene"
It is not made from graphene.
"said by its UK developers to be the first commercially viable consumer product using the super-strong carbon"
There are a wide variety of consumer products that *clime* to use graphene. http://www.graphene-info.com/graphene-products
"Manchester University, where the material was discovered in 2004":
Ok, they got this right.
"It is said to cut energy use by 10% and last longer owing to its conductivity."
LED bulbs die when their electrocaps fry. Improving the conductivity of the LED (and I can't imagine how it would do this) would not change this.
"It is expected to be priced lower than current LED bulbs, which cost about £15 (~$22) each."
Current LED bulbs are widely available in the UK for £5 to 10. http://www.mysupermarket.co.uk/shelves/Light_Bulbs_in_Tesco.html
> That way the neighbors can conduct a full jihad against Israel without worrying about losing their capital cities.
Considering that three of its neighbours lost parts of their capital cities, and two others were under serious threat, Israel doesn't need nukes to do that.
And now that we're 50 years in the future, the neighbors have a lot more to worry between each other than Israel. There will be no repeat of '67.

Cost overruns in Canada were 100%, both on initial construction and refurbs. Current cost overruns in Europe are the same.
If there is a *real* theoretical problem with nuclear power is that its economics scale with size. To compete with wind or gas they have to make really large plants. That complicates financing and construction. Construction becomes so complex that you end up with many critical paths, as we're experiencing with Vogtle. Wind power may not be a panacea, but it's highly modular so you can build out slowly. It's a lot easier to get $25 million for a turbine than $25 billion for a nuke.
The providers are dumping nuclear for that reason. All that's left of Europe's industry is Areva, which just lost more than it's entire book value in one quarter. The other German, French and UK companies have all left the industry. In the US, Westinghouse is bankrupt, Betchel, Babckock and General Atomics are all out of the industry, leaving only GE and the zombie "Westinghouse" (Toshiba). Canada sold off AECL's design side for negative $750 million.
> Roughly a quarter of the cost of nuclear power in the US stems directly or indirectly from paying lawyers to go away.
I keep hearing this number, but I can't find a trustworthy source for it. The recent documents I've seen, covering Crystal and Vogtle put the entire compliance load around 5 to 6%.
> and current designs are expected to last up to 60 years
No, they are designed to run for about 30 to 25 years, then be torn apart and re-built from new. All that remains is the containment building and the parts outside the nuclear island. This is supposed to get you a new reactor good for another 25 to 30 years (because now those other parts and breaking down) for about 50% of the cost.
However, those that have actually tried this have a 100% rate of overrunning the budgets, to the point where it's >100% of the original cost. That's why people are shutting down their reactors instead of refurbing them. The new designs are supposed to avoid these problems, but we won't really know for another 40 years.
> I'd also like to know how this compares to hydro, gas, coal, solar, wind, tidal, and any other generation method currently in use.

According to that, this is an *extremely* competitive plant. If you turn to Page 11 you'll see the problem - it seems *HIGHLY* unlikely that the plant can actually be built for this number. This is *well* below the worldwide average. They may be quoting the wrong number, this might be the overnight costs, which would put the total CAPEX (which is what's on page 11) into the 8 range depending on the financing, which makes it much more in-line with other examples.
> Price per watt for solar is in the $5 range, not counting discounts for massive purchases.
Yeah, in 2011. Today, small residential installs are around $4.00 a watt, commissioned. Large industrial installs are $1.50.
