I am not sure where Solarcoin is going. I don't know what is happening to earlier plans for it. As I wrote earlier, I thought that it was to stop being mineable in November last year, but it doesn't seem to have happened yet. The supplier of my PV panels doesn't seem interested in promoting Solarcoin to its customers, and presumably other suppliers aren't either.

Maybe the answer is for suppliers of PV panels to encourage people to register for SLR and to offer customers of their goods and services discounts in exchange for SLR, rather than actually use SLR as a currency on its own. That would encourage people to register their renewable technology. It woudl also encourage people to upgrade or expand their renewable systems.

The next big thing, and likely upgrade path, seems to be PV systems that work during the night -- by incorporating storage batteries to store excess energy during daylight hours. Remember that most people are out during all daylight hours in winter, and most of them in summer.

If SLR became part of the "carbon economy" and incorporated into solar inverters it could be very useful in cutting out bureaucracy.

Thanks for that. I have cashed out on the other one and switched back to MPH basically because I am used to it.

Coin mine http://www.coinmine.pw/ up and running and looking good. Is the server really on this tiny island miles from anywhere?

Thanks for that clarification. I looked on Google Earth and found Palau. (.pw) An interest in cryptocurrency teaches some geography.

I am not sure what this means. It doesn't seem relevant to my question about the Mining Pool Hub not showing coins.

I have received no SLR since 1 March 2015, and noted that although MPH is working, no SLR are being credited. I wondered whether SLR had been changed to "not mineable", so I therefore tried joining an LTC pool on MPH, and the same thing seems to be happening. This suggests that the phenomenon is not limited to SLR. There doesn't seem to be anyone to ask, and there is no message posted on the MPH site.

I am wondering whether MPH could have been hacked.

Does anyone on this list know exactly what is going on?

Odd that they haven't put anything up on the news folder. I also had some old SHA256 miners on Digibyte with them and the same thing happened there. The site has allowed me to take out both Solarcoins and Digibyte coins.

http://coinmarketcap.com/currencies/solarcoin/
has gone off line, but
http://crypto-prices.com/SLR
has recently reported 1.5 cents, down to 1.4 at the moment.

Yes, but priced against Bitcoin one has to take into account that BTC has gone down by about $75 over the lifetime of SLR, and the current quotation in $ for SLR is roughly the same as it was when it was announced. IE, SLR has gone down a long way and just recovered.

The thing that worries me is that once mining stops, the only activity using SLR will be the FITs being paid to generators. There doesn't seem to be any other activity, such as buying and selling of PV equipment, for example.

But we will see. Maybe it will go up up and away to $20. However I'd hate to see anyone buying into it with money they could ill afford to lose, though. It would not be good for renewables if it turned out to be like National Lotteries, a "gullibility tax".

As far as I can understand:

People who generate solar power have to send in proof of generation as provided by energy companies paying feed in tariff. Humans then allocate SLR.

Obviously this doesn't achieve anything, so the penultimate idea is for PV inverters to report electronically what they generate directly to the SLR network which will automatically allocate SLR. The energy companies, who are obliged to pay the FIT, will instead of paying it in inflationary currency, will have to buy SLR on the market in order to meet their obligations.

This still doesn't achieve much if the only thing people who generate from PV can do with their SLR except sell them on the market. So the ultimate will be for solar PV equipment to be on sale priced directly in SLR. This will cause the generation of renewable electricity to be self expanding to the point when all electrical energy comes from this source.

On the basis that all renewable energy originates from the sun, I personally believe that wind, wave and hydro power should be included, but I don't think this is planned at present.

I suspect that I have got a lot of this wrong, therefore ask people to post corrections to this thread.

Mining seems a lot more difficult over the past few days (half as many per day) and the quotation against $ seems a lot higher. ( 0.9346 cents as I write.)

The total market cap of SLR is still petty cash for people like the Rockefeller family, and may even be quite trivial at the suggested $20.

Bitcoin market cap    = $ 5,344,873,840
Somalia GNP             = $ 1,120,000,000
http://www.studentsoftheworld.info/pageinfo_pays.php3?Pays=SOM&Opt=economy

Solarcoin market cap = $          244,816
http://coinmarketcap.com/currencies/solarcoin/ (at the time of writing)
the latter is likely to be less than the value of the homes of many people who get SLR for their PV generation.
Looking at the abovequoted web page, I see that the market cap for SLR has very briefly been near to the GNP of Somalia, though.

So do not put anything into this that you can't afford to lose.

Obviously not enough. There was a lot of it. However it does not look as though it was implemented.

Having just read it, it looks as though that idea was talked down as not being in the spirit of Solarcoin.

Thanks. All upgraded now over two days.

The question remains as to what to mine after SLR becomes unprofitable or ceases to be mineable. Mining something else and converting it to SLR when SLR has a bad day seems an option. Such activity on a wide scale would continue to support SLR by propping up its market. Digibyte seems a possibility as it can be mined using old SHA256 miners as well as Scrypt miners.

but as far as I can see one would have to go via Bitcoin to get to Solarcoin.

Any other ideas on this?

The new version seems really slow "re-indexing blocks on disk". Is is possible to do this in stages, ie will it carry on where left off if the computer is switched off overnight?

I am not sure from this what has to be done to update the wallet.

Presumably
Back up the old wallet.dat
run the new installation from the download

Will it install over the old one? What happens to the address?

then what?

I don't want to do that and find that I have lost my coins or access to them.

In addition, has anyone any suggestions of what Scrypt coins to mine after that. Solarcoin had a sensible purpose. Are there any other coins with a purpose?

It seems to me as someone new to all of this that what would be most helpful would be if the software was able to define more closely what the communication problem is. I have got both a Ubuntu machine and an XP64 machine giving this "Problems Communicating With Bitcoin RPC" message and have been able to get neither to work. Bitcoin itself loads blocks and makes connections. The problem seems to be communication between guiminer, or phoenix and bitcoin.
