Alternative Energies Title: Tesla's Powerwall: 12 important facts to know Elon Musk, the billionaire entrepreneur who unveiled his Powerwall home battery Thursday, already is offering the devices to SolarCity Corp. customers seeking backup supply when the grid goes down. SolarCity expects to deliver them in October. Musk, whose Tesla Motors developed the product, is also chairman of the San Mateo-based solar supplier. Poster Comment: Powerwall (Tesla) The Powerwall is a rechargeable lithium-ion battery product manufactured by Tesla Motors for home use. It can store energy for domestic consumption, load shifting, and backup power. It was announced on April 30, 2015, and will retail at prices starting at US$3,000 for a 7kWh model beginning summer 2015. The device will be sold to companies including SolarCity. SolarCity is running a pilot project in 500 California houses, using 10-kilowatt-hour battery packs. Hmmmmm... lithium-ion batteries are interesting technology, but not without concerns regarding their safety. But aluminum batteries being researched at Stanford may eventually provide a competitive alternative.

Good to see the downward price trajectory. But I agree about the safety concerns for LI and share the hope for an alternative. The tech is still in its infancy. Have you seen this? Pretty cool.
Like the 4 ghz midtower desktop computer I am assembling
Yep. Quite a ways from the 8088 project I put together 20 years ago for fun... on a breadboard. Today's efforts in EVs are on the level of the early days of PC Clones. Parts are becoming available for hobbyists and entrepreneurs to build the future industry from. If the Apokeetards don't manage to incinerate us all first, the future is promising.
I bought one of the first IBM PCs back in 1981.
Those of us who grew up in the business have been continually awed by the advancement in PC capability. I rember gettin my first 386. It ran at a clock speed of 67 times that of an XT and had an open bank for 32 one meg memory cards. I had a wonderful 120 meg hard disk. In the 90's I bought five CD's with every published phone number in the U. S, complete with names and addresses. I found old army buddies with it. My brother has a PC with a clock speed of about three gigs and a 800 gig hard drive. He has no idea what to do with it. He just wants to say he has one.
