Comparing Tesla to existing car companies misses the point entirely. Telsa is an energy platform company that is investing in delivering (Supercharger network) and storing (Gigafactory) energy. Cars are certainly the current "killer app" today, but are likely to be followed by many other applications in the future.
- blisterpeanuts 11y agoYes, it's starting to look as though the cars are merely a shell for the very profitable batteries they're going to be cranking out in Nevada. Perhaps the whole Tesla car idea was a buyout play -- get established, build a name, then sell the whole thing to GM for $30 billion. Once the battery plant has economies of scale, they'll be fueling a whole new generation of electric vehicles by other makers, perhaps including the upcoming Apple and Google auto-pilot offerings (the Nexus car? the iCar?). Then there is the home and small office market for backup power, storage of daytime solar energy, off-grid and remote locations e.g. ranger stations in national parks. It'll be interesting to see how this shakes out.
- dragontamer 11y agoExcept those uses of energy are better solved by Redox-flow batteries, Compressed Air Energy Storage (CAES), or pumped hydro. http://energy.gov/oe/services/technology-development/energy-storage http://energy.gov/oe/services/technology-development/energy-... A single $5 Billion pumped-hydro plant can store 30 Gigawatt-hours of energy. https://en.wikipedia.org/wiki/Bath_County_Pumped_Storage_Station https://en.wikipedia.org/wiki/Bath_County_Pumped_Storage_Sta... The energy demands of this country will be met by utility companies and their massive infrastructure projects. A few hundred MW-Hrs from Tesla is pretty small in the great scheme of utility energy storage.
- crabasa 11y agoI'm sorry if I gave you the impression that Telsa is competing with utilities to store energy at scale. I meant storing energy for personal use (vehicles/homes/etc). They will certainly source all of their energy from said utility companies.
- dragontamer 11y agoThe large scale energy use projects are leveraged by personal users however. If you have net-metering, then you sell your energy back to the grid. I mean, California's energy situation sucks (and will continue to suck until they build some large-scale energy storage solutions). But the majority of the country can just use net-metering... sell the energy back to the grid and get all the benefits of stored energy without actually having to buy Tesla's Batteries.
- encoderer 11y agoHome solar is more valuable with an attached battery. Without it, most setups as sold will shutoff if your home loses grid power. A battery is not the only way to solve this but it's the best solution if you can afford it.
- dragontamer 11y agoBut that's not what people use Solar Panels for. They use Solar Panels to reduce (or even negate) electricity costs. Spending tens of thousands of dollars on batteries that only last a few hours when grid-power is lost is not a luxury the typical person can afford. But solar panels that are cheaper (and provide revenue through net-metering) will revolutionize the energy industry. The average homeowner uses 30 kW-hrs of electricity a day. So... what, three Power-Walls per day of backup energy for $10k + installation costs + inverter costs? With a power output of only 2kW? This is going to cost maybe 20k or 30k for a solution that gives you power for more than a day. In contrast, a simple gasoline generator will get you 5kW of power (6kW peak) and run for as long as you have gasoline. This crazy solution costs like $600 from Home Depo... and has several decades of experience to prove its effectiveness. http://www.homedepot.com/p/Powermate-5-000-Watt-Gasoline-Powered-Portable-Generator-PM0105007/202919571 http://www.homedepot.com/p/Powermate-5-000-Watt-Gasoline-Pow... Generator + Solar Panels is still looking a hell of a lot more practical than Solar Panels + Battery. $50 of gasoline is going to run you ~25 gallons, enough to last 2+ days without any power. And if a crazy hurricane "Sandy" situation occurs again, you can always go out to the local gas station to grab more gasoline for day 8, day 9, or day 11 without power. I mean, seriously? 10kWh per PowerWall is laughably small. ---------- I mean, when do you lose power for extended periods of time? Answer: when major hurricanes or snowstorms hit. That's what. It isn't like your Solar Panels will work while they're completely covered in snow. You'll need the generator if you actually want reliable off-grid energy anyway.
