Comment Wait a Second, Fanboy (Score 1) 296

Why not just buy the batteries and charger and skip the cost of the car?

Depending on source, Japan's electricity cost is 50-100% higher than the U.S. At $20k per car and the above $800/yr per car saved (In U.S.$400-530), what is the return on investment per year (this question doesn't include upkeep like maintenance cost of the car)?

How fast do you wear out the batteries due to the increase of charge/discharge cycle?

Comparing the savings of time shifting usage with approx $120,000 cost of the cars, what could the same company do to reduce consumption using $120,000 to reduce energy consumption (therefore reduce amount of the evil CO2 created)?

How many mile will you loose if if the cars are used for commuting?

Cell phones were cheaper with many millions of land lines not laid. The fiber or copper for the cell towers would have been used anyways as part of the land lines so were fixed cost anyways. Oh and other countries/charities also gave them money. Now we tell them to place millions more solar panels and windmills and hundreds of natural gas plants as low supply backups.

Yeah, you can jump to 100% clean energy too! Just pay triple on your electric bill. You even can jump to an electric car for only another 6k above the gas model. So, money on green power or money on a Obamacare plan cause Ocare law let the your insurer drop the plan you wanted to keep? They get the choice of clean energy or food.

And more in 10 other Asian countries. This is a twofer: Let's loose money by not making loans on a nearly fool proof business model and let those countries become ignore the U.S more for their new friends who will do what they want and we don't!

Comment Leftover jobs (Score 1) 674

The problem of more tech is that the new "jobs" are further and further from the source of value/product creation. Each of these new jobs give diminishing returns on useful output and therefore pay less. It's like a private sector "jobs" program, but one that requires more and more irrelivant $100k degrees.

I'm one of those right wing nuts that yell, "Get a job, slacker." but there's less to be had and we will need some kind of mandatory, permanent payments for those who do not work.

And we ran out of oil. The ozone's gone. We're in a nuclear winter. " ... In the 1970s hundreds of millions of people will starve to death ...". I guess Paul Ehrlich was right. The sky fell.

I'll keep my "end is upon us" sign in my closet for now.

In industry, they're using it to transfer all of the energy they payed for through compressed air. It's the primary source. Excess waste energy cost the exact same if you use it or not, but you get more energy out of it if you can store it for later in stead of no energy at all.

With a giant "free" salt mine tank and with a small power requirement (10's MW) , the cost of storing the energy might be cheaper even with all of its inefficiencies than the cost of using batteries or buying it off the grid. The "wind mine" isn't wasting 85% of all your energy, but 85% of "free" excess energy.

My gut says that it would be cheaper to buy the power, though.
