From TFA:

The company created a subsidiary called ACCUmotive in 2009 to develop lithium-ion batteries. It built an energy-storage array that is now operated by German electricity joint venture Coulomb. The system's 96 lithium-ion "modules" boast a combined 500 kilowatt hours of storage capacity, which is used to stabilize the Saxony Kamenz power grid. There are plans to expand this installation to 3,000 kWh of storage capacity.

The Tesla Battery's cost $13,000 would pay most people's electric bills outright over it's life.

The Tesla's battery is also 53, 70 or 85 kWh whereas the average household uses around 1 kW (kWh/h) and certainly can get by with a few kWh of storage to handle its overproduction of solar during a day.

In the end, it's just economics. Does solar + battery pay itself back in lowered electricity bills? If it does, nothing else matters.

The difference between 25 and 40 € isn't that big. Depending on where exactly you are and want to go in Helsinki/Tallinn, it may well be more convenient to take a train.

Heck, people ride the metro for nearly half an hour to get downtown for beers. If I can get to a decent Tallinn pub in less than an hour door-to-door I'd probably go now and then, depending on how late in the evening I can get back home.

For those who don't know, alcohol and restaurant food are around half the price in Tallinn compared to Helsinki.

Well, I remember Scott Aaronson saying de Broglieâ"Bohm's pilot wave theory requires exponential resources to simulate even with a quantum computer. Ergo even if it makes some things easier to understand it's not generally the most useful way to think about QM and arguably in some sense can't be the way Nature does what it does.

In space, no one can hear you fart.
