True. On the other hand lithium ion batteries are heavy and their capacity deteriorates over multiple charge cycles. In particular for heavy vehicles and aviation hydrogen might prove superior.

Why would you need to do that? You produce hydrogen via “direct-air electrolysis” and then use it as a fuel by reacting it with oxygen in a fuel cell. Compared to lithium ion batteries it’s just a different chemical medium for storing energ

> That power source could just as easily turn an electric motor directly, so you really need to ask yourself: why exactly do we need the air? More often than not, the hydrogen intermediate is just a glorified battery. That seems like exa

ICEs have the same problem though. If they don’t rotate fast enough they stall. For ICEs we solve the problem with gear boxes. Couldn’t the same solution have been used for steam engines?

You’re looking at nominal GDP measured in USD over a period when the value of the yen fell significantly relative to the USD. If you look at the trend you can clearly see the nominal GDP fell back down to trend after a massive spike during

Looking into this it looks like an oddity of trade statistics / bad reporting by the WSJ. Singapore is both importing and exporting large amounts of high tech goods. For example it imported 8.7bln USD of gas turbines and exported 9.2bl

Your right! I was just looking at it from the point of view of how efficient does this standard require power plants to be, since 270g of CO2 to run a 1kw heater for an hour seemed high. If you look at the whole energy supply chain though t

Intuitively 270g per kWh seemed high to me, but to put it in perspective a Tesla model 3 does about 100km per 11.9~14.9kWh (according to Google). So taking the larger estimate (and ignoring transmission etc losses) at 270g/KWh that giv

FWIW. This would probably present a challenge in most (all?) languages. For example in libc++ due to SSO an std::string has a minimum size of 24 bytes. For a billion strings less than 15 chars (+ the null byte) that gets you to 24GB, and th
