According to New Scientist, mathematicians have found a new way of adding two integers together that is faster than the method currently employed.

Using the common algorithm of sticking one number over the other then multiplying the individual digits, it would take a computer six months to multiply two billion digit long numbers, so they found better algorithms that used logarithms to shorten the process.
The new method has shortened the process even more, but there's a wee bit of a drawback, it currently only works on numbers that are more than 20 trillion trillion trillion digits (that's a 20 with 36 zeros after it) long. :cheesy:
Still, there are bound to be some applications that use numbers that big (climate modelling?)

Germany use a lot of brown coal (Lignite?) in their electricity production though.

They do, but presumably that's taken into account. Do we have any coal-fired stations left? I'm not sure, and we've had more than a few days this year when renewables have powered the entire UK for days at a time. We have the biggest offshore windfarms in Europe. I'm not sure where we lie in world rankings.

Of course wind turbines are extremely expensive to make in terms of manufacture, maintenance and the materials themselves.

Apparently they take about 8 months to offset their manufacturing carbon costs.

CXL Compute eXpress Link, is a new standard for connecting high-speed CPU-to-Device and CPU-to-Memory, and is backward compatible with PCIE cards, which is good
