You don't need to in the general case, although the only practical way to do so in this case is via the ocean.

Tritium can be refined, and is done for various applications (radiolabelling; nuclear weapons; nuclear fusion). However it's expensive, as is reflected by its cost of about $30k per gram. It'd be even more expensive to refine from

The same release from a vessel in open water is less likely to damage an ecosystem than release from the shoreline. That said, if it's diluted enough and released over a long enough period of time, it's unlikely to make much diffe

The problem is that you have a large volume of radioactive fluid. The radioactivity is "low-level" but still poses a danger to health and life. If you store it somewhere, you have to be sure it will stay there. Additionally, if it

This was my thought also, although it may not be trivial to just hire an oil tanker to transport radioactive water. Before dilution, there may be a significant risk of contamination to the vessel and crew. You'd probably need a special

Yes, but an effort to port XFCE to GTK 3 is underway. My understanding is that this will bring Wayland support.

I don't think the fundamental problem is being publicly traded, it's a question of how distributed the control of a company is. Some publicly traded companies are controlled by few people. When ownership is concentrated, decisions

I mean that if it's better than what is typical, then it shouldn't be inadequate, and that helps justify this trade-off in favour of efficiency / range.

Being able to store data densely on a commodity material such as quartz is great for archival storage (e.g. Amazon Glacier). If the storage media is cheap, then it tends not to matter if it can be reused. For random access, rapidly created

To save others time, "unsprung mass" is the mass of the vehicle not supported by suspension. Lightyear's claim is that putting the motors in the wheels improves control. Could it be that unsprung mass is reduced by negating t

More efficient conversion of sunlight electricity doesn't mean the cells are cost effective for putting on a house. On a luxury car like this, area is constrained and money is no object, so it may make sense to use otherwise prohibitiv

But the temperature was 462K (about 189C), far beyond room temperature, or what we'd expect to store data at. This is just the temperature at which the expected lifetime is the age of the universe, which has no bearing on the technolog

I find it interesting that the interpretation is that this is a tragedy, rather than it being fortunate that a geological process is capturing plastic into the lithosphere, where it will be removed from the biosphere.

It would be much harder to engineer: you'd need a hefty tank; cryogenic fuel handling to increase density and lower tank weight. Safety is critical on aircraft. Hydrogen is difficult to contain, and has very low viscosity due to its sm

Propelling air to move on the ground is far less efficient than wheel propulsion. You have to give the air at least as much momentum as the vehicle, and without a very large propeller, this requires accelerating it to a high velocity, givin
