A "solar still" is a device used for purifying water from damp waste or brackish water
Solar is still pretty much a novelty. Less than .1 percent of all power comes from solar. Hopefully, the science will evolve to the point it will become a workable alternative.
An antapex is a point opposite a solar apex.
The current sub-solar point is the point on Earth's surface where the Sun is directly overhead. Its location changes throughout the day due to Earth's rotation and the tilt of its axis. You can track the sub-solar point in real-time using online tools or apps.
No. It is still in the solar system.
The concept is still being worked on today. No commercially available cars are yet produced. The engineering is still on going.

Cloning is new. Asking if it is still in use is like asking if people still use solar powered lights. It is new and currently being developed but has made many advancmnets
The "sub-solar point" is the point on Earth where the Sun is straight up, at a 90 degree angle to the ground. This point moves around the Earth each day as the Earth rotates, and appears to move north and south over the course of the year. The sub-solar point is exactly on the equator at the moment of the two equinoxes. In March, the sub-solar point is moving north as it crosses the equator; in September, the sub-solar point is moving south across the equator. In June, the sub-solar point creeps up to the Tropic of Cancer and then heads south again. In December, the sub-solar point gets all the way south to the Tropic of Capricorn at the winter solstice.
New planets are more or less constantly being discovered outside the Solar system. There are almost certainly no unknown planets still lurking within the Solar system, though.
It is the sub-solar point. It is the point where the Sun is directly overhead. The sub-solar point has a latitude equal to the Sun's declination at any moment, so all points on Earth between latitudes of ±23½ degrees can be the sub-solar point. If you want to know the direction to the sub-solar point at any instant from where you are, just point at the Sun and then move your arm vertically downwards so that it points horizontally. If you want to know the distance to the sub-solar point, measure the Sun's angle relative to overhead where you are. The distance (in nautical miles) is 60 times that angle in degrees.
Quite simply, you get less solar energy than when it is not cloudy. For example, a solar stove can still heat water, but it will no longer boil.Quite simply, you get less solar energy than when it is not cloudy.

We don't use it because at this point in time, gas is still cheaper to produce than solar panels and wind turbines, and produces more energy. Until the world runs out of fossil fuels, the alternatives will still be alternatives.
