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.
He really is among the best heads up no limit players though.
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.
