German solar power plants now able to produce electricity equal to 20 nuclear power stations at full capacity, enough to meet a third of its electricity needs on a work day, Friday, and nearly half on Saturday when factories and offices were closed

Much solar in Germany is installed by private owners on roofs. Check out some pictures of southern Germany some time.

Solar is just getting to the size when it matters. Thus you see these numbers of 22 GW on a sunny. Expect to grow it further. In a decade Germany should be at something like 50 GW.

The government is also not subsidizing it. The solar expansion is financed with a feed-in tariff paid for by the electricity users.

Germany is not only investing in solar. Renewable energy in general is the target. We are now at over 20% electricity from renewable energy. Expect 40% in 2020.

In Germany the remaining nuclear power plants have around 1.4 GWe each. Most plants now have a single reactor left.

What it makes difficult is also the relatively small address space. There were Lisp implementations on the 65XX, but they were not very capable. Lisp Machines originally had been invented in the 70s to provide users with more memory for their Lisp programs and to free them from the performance/space limits of time-shared computers. Thus Lisp Machines were among the first personal computers. They started with several hundred KBytes memory. Commercially sold machines in the very early 80s had something like 4MB (1 megaword of 36bits). The smaller (memory size) Lisp Machines from Xerox lost a lot users because memory was more limited. These large memories (and their special memory architecture) made the early Lisp Machines very expensive. A 1 MW memory board could easily cost $10k.

My Symbolics 3640 Lisp Machine has a 68000 as a front end processor.

There are earth quakes in some areas of Germany. We've even seen Tsunamis in the North Sea in the history.

Useful Lisp implementations on personal computers appeared with the Motorola 68000 processor and on Intel x86 processor machines. Mid 1980s.

Given the very low acceptance of Nuclear power in Germany, I would not have expected that. Given that Germany gets more electricity from coal, I would have expected that it would be more difficult to shut down coal.

Given the very low acceptance of Nuclear power in Germany, there was a common view in the German society to shutdown nuclear as fast as possible. There are different views how fast it is possible. Some want it much faster. But the need to do so has been seen by the majority of people here.

That does not add up. Germany had 22% electricity from nuclear in 2010. 44% from coal. The exit from nuclear takes another ten years. It's not easy to see how we can get rid of 44% of electricity when we have a hard time to replace 22%.

Face it, there is no acceptance of nuclear energy in Germany. OTOH there is a broad consensus to transform the electricity production to mostly renewable.

That means we will also replace coal during the next decades. The market for new fossil fuel power plants is already dead. There is also a large opposition againts new coal power plants.

That's a good question. I would not expect to find useful numbers. Say, in 2050 Germany might import around 50 TWh renewable energy (electricity) from other countries (of around 500 TWh total demand). It's not said where this electricity will come from, but Norway would be one source. Power lines are planned or under construction. Another question is how much pumped hydro storage Norway will develop - it also has an impact on the environment. It could also be that Germany has new forms of pumped hydro then (like in old coal mines):

It's always the same. Try to get independent information. Why do you think japanese citizens are monitoring radiation themselves now? Few trust Tepco or even the Government.

None of them trust anything TEPCO or the government says.

http://ajw.asahi.com/article/0311disaster/fukushima/AJ201105270256

Survey: 73 percent of Japanese do not trust TEPCO

Who would expect that tepco admits anything. In the past the company has been several times caught at lying.

If somebody had symptoms of Leukemia and he is about to die in a few days, these symptoms should be enough to not allow him to work in this high stress environment.

1 week is too short for developing leukemia. But the prior examination of the person found nothing and after a week working at tepco he dies?

Doesn't answer the question. Try again.

How do they feel about more earth quakes?

Maybe in your country where coal power plants have no filter systems.

What do you think, how much radioactive cesium has been released by the Fukushima accident vs . the Japanese coal power plants?

If somehody dies of Leukemia, I would not be surprised if it is caused by working at the plant. The incubation times can be short , which is known from cancer treatments.

The japanese won't use nuclear then. None of the reactors is producing electricity...
