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 on my dining room table? Eh? Do you think four gigs will improve the quality and relevance of your posts here or elsewhere? As far as I'm concerned, for serious scientific or engineering work, a two gig computer armed with 64 bit DOS BC7 professional BASIC, if we could get it, is sufficient to do anything imaginable.
Most scientific computing today involves analyzing terabytes or even petabytes of data. You are not going to do that with basic on a desktop PC.

But Cray's of "not many years ago" weren't processing peta-bytes of data.
