Is the energy of lightning usable?

It would be handy if you could catch the energy of lightning strikes; it is about a lot of energy. Sometimes the current is 200,000 amperes, and the voltage is millions of volts. If lightning strikes somewhere, up to 10 gigajoules jump from cloud to earth; enough to keep 10 60-watt lamps on for six months.

Electrical stimulation awakens people from their coma

Severe brain damage, poisoning, a serious lack of oxygen or diabetes can cause a person to fall into a coma. And then the question is whether he or she will ever wake up again. To date, people in a coma could not be helped in any way. But now researchers have succeeded in waking people out of their coma with electrical stimulation for up to a week.

Do you get a beer belly from too much beer?

In a large German study, scientists followed 20,000 men and women for eight years, until 2009, and compared their beer consumption with their weight and waist. The conclusion was that men with a big belly took more calories than they consumed, whether those calories came from beer or not. In men, the excess kilos on genetic grounds are mainly in the belly fat, and in women the sex hormones ensure that the majority of the fat ends up on hips, buttocks and thighs.

That is why it helps to restart electronics

If very heavy programs are running on a telephone or computer - or many apps at the same time - this requires a lot of the memory (RAM) of the electronics and the processor power. If you restart the device, the control is moved from the operating system (such as Windows or iOS) to the so-called bootloader - the only program that is physically built into the computer.

How do you measure energy in food?

We measure the energy value of food in a 'bomb calorie meter'. This consists of a sealed, insulated container that is immersed in water. In it we put food of which we want to measure the value, after which we close the container and fill it with pure oxygen. We light the food with a spark system.

Why didn't the universe disappear immediately?

Solar flares in 2 minutes: the sun shuts off the power

PROBLEM: Solar flare sends plasma onto the earth. The sun runs from north to south magnetic field lines. At the equator, where the rotation of the sun is fastest, they are stretched the most. By being pulled, the field lines can break through the surface, so that huge clouds of electrically charged particles, plasma, are hurled in the direction of the earth.
