Japan to phase out nuclear power
Source: Financial Times
Japan will phase out nuclear power by 2040 marking a big policy shift and the first formal decision to retreat from atomic energy since the disaster at Fukushima 18 months ago.
The plan, which was announced on Friday, is opposed by business groups and has been questioned by officials from the US, the UK and France, and means Japan will join Germany as the second leading economy to turn away from nuclear power since last years accident.
Tokyos timetable is much slower than Berlins, however. Angela Merkel, the German chancellor, ordered half her countrys nuclear plants to be shut last year and pledged to replace the rest with renewable energy sources over the next decade. Japans plan would give it almost 20 more years to accomplish the same goal.

The fact that one of the major nuclear countries is pulling out will not help the industry at all internationally people will ask why, said Daniel Grosvenor, head of Deloittes nuclear team in the UK. Many countries took a pause after Fukushima, and they might do so again.

(9,137 posts)Solar exergy transformed into ATP-chemical bonds (http://www.emc.maricopa.edu/faculty/farabee/biobk/biobookatp.html), not fragile at all, can't beat the "solar power" that life as we know it is based on.
BTW Greek word 'Phosphor' means etymologically same as Latin 'Lucifer', "Light Bringer".
Uranium is no solution to anything.
a geek named Bob
(2,715 posts)1.) I've never met an engineer that uses the term "exergy..."
2.) ATP is kind of hard to turn into electricity...
3.) Uranium has been successfully harnessed into electricity via atomic batteries... ATP, not so much.

(21,317 posts)It will be interesting to see whether the sustained commitment of technological resources of the Japanese society can solve that problem.

(2,715 posts)1.) a gas pressurized fractal capacitor (up to 3 WH/cm^3. That works out to about 20 WH per cubic inch - that's roughly 8 "D" cells to the regular "D" cell.) You only need 1 ATM of CO2. (This way, we also use up excess CO2!)
2.) Micropore H2O2 fuel cells (Using the old Apollo style FCs, we get something like 33 WH per 18gm used. A micropore cell should be about the size of a soft drink can.)
3.) Flywheels with magnetic bearings. You can get up to 900 WH per KG of flywheel. (The only problem is that, when mag bearings go, they go bad)
Just a few quick ideas...
daleo
(21,317 posts)I have often wondered whether storage via gravity has been fully explored, either by pumping water uphill for later use or other mass e.g. A power plant that used solar during the day to lift large concrete blocks, then released the stored energy at night by letting them slowly fall back to earth, driving a generator while doing so.
a geek named Bob
(2,715 posts)It's not very efficient.
Still... You use what you have on hand...

(2,715 posts)As to the laser cutter to light smoking materials...
It might canoe the particular material...
LOTS of power in that cutter (It's a good 150 Watt IR laser.)
If you really want to light your "bound collection of flowers," do it old school...
I use an old blowtorch.
At the moment, the whole place has sort of a garage-band/Mad Max feel to it. It's fun!
New Haven is one of the few places I know, where you can walk out of the Amtrak station, grab a coffee in a disreputably fun jazz club/bar, go build a robot, and then get a good pizza, all within walking distance.

challenges, and these challenges have mostly been met and successfully
dealt with. It does take time, though.
Atomic power has been around for about 60 years, and is proving to be
very dangerous. Some think the dangers outweigh the benefits.
Also, small Old World countries have problems different from larger ones.
Japan is about the same size as California, but has 4 times the population.
Japan is an old country. The same applies to most countries of Europe --
too many people living in a small area. By the way, that's how our nation
was formed in the New World. Europe became too crowded, the people
simply had to expand into other less populated areas of the globe.
a geek named Bob
(2,715 posts)also, as to the issue of "too many people"...
I'd MUCH rather live in a city like San Francisco, than some podunk village.
Hell is a small town...

I'd bet a fair amount that a city could go self-sufficient, given some planning.

(31,849 posts)I do not see moving away from a fuel source that has the potential of rendering large portions of our world uninhabitable and creates an ever increase amount of waste products that can do the same thing as sad. Especially, when there are alternatives like solar or wind that in a waste case disaster, might harm a dozen or so people.

(2,715 posts)Solar power is only good, if you're going to have really low density population centers (AKA forget cities).

a geek named Bob
(2,715 posts)If we can somehow get perfect efficiency of 100%, then we get a max power of roughly 43 watts/foot square.
Assuming a home needs 1000 watts, which is about 1/4 normal, we need roughly 25 square feet, assuming no trickle charge for dark hours. Call it 50 square feet for the total. If the building has a foot print of 1,000 square feet, then we can have 20 families.
But we can't get 100%. We recently had a breakthrough, and moved up to 40%. That means about 8 families.
Am I making my point here?

(7,672 posts)Too much government money in the heavily subsidized industry which is the filthiest, most expensive, most dangerous way ever invented to boil water.

(9,893 posts)will return to coal, which is incredibly filthy.
Renewables will help mitigate the situaion, but Germany is too far north and too cloudy to really go with renewables exclusively, although it does have wind power.
Japan is also too far north and cloudy for solar, and I don't know if they have good wind power sites like Germany.
We are living in interesting times.

(7,672 posts)days, and anyone with a coast has plenty of wind as well as wave power.
My concern is that I live 30 miles from the only nuclear waste dump in the US, put there by bribery and deception and right on top of my water supply. Considering there has never been a nuclear dump that didn't leak, I worry.

(7,672 posts)OTOH, I'll just enjoy my 5.6 cents per KWH wind generated electricity.
NickB79
(19,297 posts)Actually, that answer is partially true, in that solar panels aren't as efficient in cloudy conditions as during bright, sunny days. In fact, the production of solar panels is reduced by at least 50 percent on cloudy days, and may even by down to just 5 to 10 percent of what they can produce on sunny days.
mbperrin
(7,672 posts)Good. Thanks for joining the reality-based community.
NickB79
(19,297 posts)YOU stated:
My link clearly shows it does, sometimes drastically. No one here said solar WON'T work on cloudy days. What everyone has been trying to tell you is that clouds can SERIOUSLY reduce the amount of electricity put out by them.
Welcome back to reality.
amandabeech
(9,893 posts)No one has ever invested in solar power in the area, and I go back to the '70s with this.
Now, large wind turbins are going up, and more are planned.
Nonetheless, there is little belief that the wind turbines will replace all the fossil and nuke power running through the lines.
I stand by my original post.
NickB79
(19,297 posts)It's just that we won't be able to piss away electricity so wastefully like we do now. Hell, once resource depletion and global warming really take hold, we won't be able to use electricity on some of the VITAL stuff, much less the non-essentials.
But that's the path we seem to have chosen, unfortunately.
PavePusher
(15,374 posts)So you have now doubled-down on your moved goal-posts.
You need to either clarify what your intended meaning was, or... something...
mbperrin
(7,672 posts)power is nuclear, and the nuclear dump that just opened 30 miles away over our water aquifer will only make our water taste better.
Oh, and the electric company that charges me less than 6 cents a KWH? They must be fools, because they can't be making electricity from wind at all.
Better? Happy? Satisfied? Good. I aim to please.
PavePusher
(15,374 posts)You must need a chiropracter after all that heaving at goal-posts.
Have a great day. It's beautifully sunny here in Tucson, where my Air Force Base has a nice large solar generation field, and is installing solar panels on all new construction.
Time to go refill some growlers on my way home.

They'd like people to think Fukushima is over. A plant that can't be decommissioned for 40 years in a severe earthquake zone is not exactly "over." The contamination is not over.
