Look that the second graph "Death Rate per 100,000,000 vehicle miles. The trend is downward, and the rate is less than half of what it was 40 years ago. Over the last 60 years, deaths and death rates have dropped significantly. Granted, things have been relatively flat since 2014.
None of those graphs show "ever-increasing carnage."
Deaths and Death rates have been (mostly) decreasing.
Tesla has been selling rear seat heaters as a $300 software upgrade in its Models 3 for a while now.
I have an oscilloscope in my office that is software limited to 2.5Ghz. The software upgrade tp 10Ghz is three times what I paid for the oscilloscope.
Think about a computer. The hardware is there to run photoshop, but you still have to pay extra to run photoshop.
And for the bargain price of only $2B Euro.
Sure, pumped hydro-storage a huge tunnels are kind of neat, but is it really worth the cost?
Is it a reasonable way to generate power? 500MW is less than 1/6 the power of a typical commercial fission reactor (It takes about 3GW of fission power to produce 1GW of electricity.). It would take 10s of thousands of ITARs to generate enough electricity for the world.
I get the idea that maybe will will figure out ways to get more power or scale down the size of the tokamak but it seems we are starting from a pretty serious disadvantage.
It is big sciences and cool and all. I am not against doing the experiments, But pinning ANY hope of this being a solution to the worlds energy needs is extremely far-fetched.
You use the neutrons to fission Li6 to make more tritium for the reactor. The lithium fission reaction also produces a lot of energy.
...company consumes seven megawatts of power each month—enough to power 19,600 homes...
I assume that the bitcoin mine has a constant draw of 7MW, and not a monthly use of 7MWh.
That comes to 357W per house or 258kWh a month. Average for a house is nearly 4X that.
"The second point is why I think DC fast charging is not as necessary as many people believe - a level 1 or level 2 charger is more than adequate."
No. Just no.
Without fast DC charging, you have an expensive vehicle that can never leave your metro area. I bough an EV to replace a car -- a car that I actually take on vacations, not as a city vehicle.
Yes, 80-90% of my charging is done at my home in my carport. But that other 10% is _extremely_ important, and I would not bother with an EV if it were not there.
Let me use a car analogy: 80% of the time I am not only occupant of my car. Why do I need a passenger seat and rear seats?
Providing an adequate fast network to handle holiday surge traffic (when EVERYONE is trying to go someplace far off at the same time) will continue to be a major challenge for EVs for the next several decades.
Why can’t the battery management system detect a shorted cell and sound an alarm? There are only a few thousand cells, it could not be that hard to detect an abnormal voltage on a single cell. Even a few minutes warning could greatly reduce collateral damages.
3D TV was dirty-cheap for the manufacturers to offer. It was extremely simple technology. It was a regular TV with different software and _tiny_ bit of (cheap) extra hardware. Manufacturers were hoping consumers would pay a premium for it. They did not. Manufacturers were not out of ideas for product improvement. They could make the sets bigger, make the color better, add resolution, increase framerate, and add motion smoothing...The exact stuff we are seeing today. The problem for manufacturers was that unlike 3D TV, that was not cheap to manufacture and was not going to be free money.
Like 3D TV, foldable phones are likely going to be a gimmicky product looking for a market that probably is not there.
I would think that all coal power plants would have similar carbon emissions on a per GWh generated basis.
Which makes the statement about 73% of emission coming from 5% of the plants true but absolutely meaningless.
If a photon has a high enough energy, can it spontaneously decay into matter and ant-matter?
Exit exams are stupid. I never had to take them.
For BEVs, we would need about 20,000 new fast charging stations and approximately 160,000 new fast-charging stalls. That is not going to happen in 8 1/2 years given that it is taking 2-3 years just to PLAN a new charging station.
For hydrogen, there is not enough platinum being produced to build anywhere near enough fuel cell with today's technology. An automotive fuels cell requires about 10 times more platinum than a catalytic converter, and about half of current platinum production is going into catalytic converters. Ramping up production to the levels required will not be easy (may not even be possible), doubly so in less than 10 years.
Plug-in hybrids actually could happen in this time frame, but no one will be happy about it.
Edward Jenner developed the small pox vaccine in 1796.
One small step for man, one giant stumble for mankind.
