Comment Negative Dark Energy, WTF? (Score 2) 90

So dark energy is invented to correct for some discrepancies in observation and theory, but not it is shrinking and might become negative? Seems like a swag based on a swag. Recent research suggests that "dark energy" isn't needed to balance the physics because in fact there is a huge amount of actual dark matter in the universe. Not some unknown particle, but just regular matter that is cold and hard to observe between galaxies. https://ancillary-proxy.atarimworker.io?url=https%3A%2F%2Fwww.science.org%2Fconten...

My 9-year-old Sunnyboy SMA3000 and SMA4000 inverters can each run a 1500W 120V plug if the grid is down. It isn't automatic (I need to turn off the power main and turn on the inverter), but it would be useful in an emergency to power my freezer and water pump if the power is out. Having a PowerWall or two would be more convenient, but we don't have enough blackouts or any time-of-use pricing for this to be worthwhile yet.

There are lots of trucks doing short-haul deliveries that can get by without a huge battery. Truck drivers also have legal maximums to the number of hours they can drive in a day. Stopping for an hour in the middle of the day to recharge the batteries and eat lunch doesn't impact the total distance a truck can travel in a day.

One of the issues with the Leaf is that the battery packs don't have active cooling like most modern EVs, so they degrade a lot faster than a Tesla with coolant in the battery to maintain the temperature (not too hot or cold). Partly that was for cost reduction, but partly it was also because the Leaf was one of the first mass market EVs and a lot has been learned since it was designed. So yes, Leaf resale values are not great, but they shouldn't be held up as how all EV market resale values will be in the future.

Comment What is an "aftershock"? (Score 1) 37

What is the difference between an "aftershock" and just a smaller "earthquake" on the same fault line? Clearly there will be some ongoing "settling" action on a fault line after a huge quake, but to say that seismic events 100 years later are "aftershocks" of the original event and not just events themselves is belittling the destructive efforts of fault lines across the planet. They deserve recognition on their own and not be overshadowed by seismic events of the previous generation.

Comment Tragic e-waste of Recycled Stories (Score 3, Insightful) 106

In other news, the excessive recycling of stories on Slashdot continued unabated, with billions of clicks wasted each year when the editors didn't care enough to read their own website and filter out duplicates.

One longtime Slashdot reader even went so far as to write a self-referential tragi-comic comment in the vain attempt to reduce such events, with the full knowledge that this too would be doomed to failure.

Comment Too bad they didn't plan this 5 years ago (Score 4, Interesting) 72

One of the main reasons that Tesla is dominating the EV market is that EVs are not an afterthought for them, like all of the big ICE manufacturers that were dragged kicking and screaming to the table.

Tesla had 10 years to ramp up their EV/battery design and roll out the supercharging network, before the Big 3 even thought about it.

Now that they are trying to ramp EV sales they realize they need chargers or customers won't buy. Tesla has chargers all over NA, and all the ICE latecomers have their balls in a vise because they cars need to use NACS (Tesla) chargers to be able to sell, but also know this will just entrench Tesla more and allow them to expand their charging lead even further.
