Lithuania is pioneering a scheme to allow city-dwellers who do not own the roof over their apartment blocks to buy solar panels located in special rural parks for their cheaper energy needs.
"You invest upfront, but then for the next 20-25 years you save on electricity costs," said Vytautas Plunksnis, who bought a 1.5 kw panel located at one solar park.
The park is situated next to an old decommissioned gas power plant which was blanketed in snow this week.
"It’s winter, there’s very little sun, so I cannot say that I have much savings, but I understand that most of my electricity will be generated in summertime," Plunksnis said. （Reuters）
Lost Passwords Lock Millionaires Out of Their Bitcoin Fortunes 丟失密碼讓百萬富翁無法取得他的比特幣財富
Stefan Thomas, a programmer living in San Francisco, has two guesses left to figure out a password that is worth about $220 million.
The password will let him unlock a small hard drive which contains the private keys to a digital wallet that holds 7,002 Bitcoin.
The problem is that Mr. Thomas years ago lost the paper where he wrote down the password for his hard drive, which gives users 10 guesses before it seizes up and encrypts its contents forever. He has since tried eight of his most commonly used password formulations — to no avail.
Of the existing 18.5 million Bitcoin, around 20 percent appear to be in lost or otherwise stranded wallets, according to the cryptocurrency data firm Chainalysis.
