An airplane will weigh less, the more jet fuel it uses. A battery powered airplane does not have an obvious way of losing weight in this manner, further limiting range. Talking about 5.000 km is hard: While it won't get you from London

You are skipping a crucial variable: Capacitance Factor. New nuclear power plants come in at 90-95%+, while lower for both solar (10-25%) and wind (22% for onshore and 36% for offshore in 2018). This means that 1GW of nuclear power will, on

The battery isn't the source of the energy. You are missing wind and solar (which isn't free), an electrical grid overdesigned for the peak-energy requirements (since you will not get all of your energy over the course of a day).

Of course the probability is never 0,00%. But it is obvious that the Fukushima accident happened due to geological factors. The same power plant would hum away nicely in Germany to this day, where there is little to no seismic activity and

One view of this is that the question ought to be whether or not those people are right in assigning blame to anyone. If the scientist is fully aware of the risk and willing to use himself as a test subject, it's hard to argue that the

While an interesting problem to try and solve (in theory, not in practice!), one has to be very much aware of where those 11 votes had to be injected for the “hack” to work. You basically need to have a somewhat precise picture of the propo

No, it’s about the economies of scale of building 50 power plants per year vs 1 per 50 years. Knowledge and know-how is lost and that increases costs. Wind has become cheaper (but not more reliable) because thousands of turbines are being i

The NE555-timer is quite a cool little thing. More common operational amplifiers are also worth looking into (TL072 is one of my favorites). Lastly, the 7400-series logic chips are SO interesting. If you need the programmer's version o

You’re missing the point. If your sales tracking alone takes up 16GB of RAM on the client, that isn’t scalable - and potentially a horrible experience to work with. Your point is correct in the single case, but I think we’re discussing beyo

I’m pretty sure that using two phones offsets any environmental savings from a single cable by quite a bit. Who knows when the EU will crack down on that kind of splurging?

The projected battery production in 2080 will only cover about 0,01% of Europe’s electricity demand. Batteries are not scalable and hydroelectric dams have their own geographic requirements which can’t be met in flat countries like The Neth
