Password Pill - Eat it and unlock any device

The scientists are working on a new technology of password pills. The main idea is to swallow a pill with a microchip that dissolves in stomach acid and emits an EKG signal. As long as the pill is still in your body, you will be able to unlock any electronic device. In the future, the similar pill could also be used to unlock cars, doors and anything else. The pill has been tested for smartphones and it has been effective. The main idea is that it is a safe method that protects your passwords and makes you safe from hackers (because they don't know how to unlock the device since they are not familiar with this new technology). We could  certainly hope  for more improvements in this area.

Night vision - wikipedia the free encyclopedia

Humans have lower affinity to night vision than many animals and in many cases it is not sufficient. Therefore, scientists have developed many types of night vision devices that helped creating the night vision concept. The traditional night vision goggles are too expensive and inconvenient. Therefore, the scientist are inventing new concepts, such as  night vision drops and night vision contact lenses.

Night vision eye drops 

Night vision eye drops might sound like a futuristic concept, but the first experiments have already been performed on a volunteer. He was able to retain the night vision and there were no side effects. Night vision eye drops are based on chlorine e6 that is present in marine organisms. 

Night vision contact lenses 

Using contact lenses instead of goggles would be a convenient solution for application in night vision. Scientist are developing night vision contact lenses that are based on graphene technology and their application will be wide in the future.

The future trends in wind power harvesting

Wind power still encounters many difficulties and it is necessary to research the new methods for harvesting of wind power. The main future trends in wind turbines are related to new designs and completely new concepts that will help to increase the overall efficiency. 

Bladeless wind turbines

Wind turbines kill birds and that is a fact. In order to solve this problem, it would be wise to use bladeless wind turbines. The main problem with bladeless designs is the fact that they are still too small and have low efficiency. In the future, the scientists should find the more effective bladeless design concepts that will involve closed turbines, low and high pressure turbines and artificial wind trees. 

Airborne wind turbines

If you want to get higher yields of wind power, you should launch the turbines high into the air. Scientists are already experimenting with balloons, kytoons, kites, tethered airplanes and other flying objects that will lift the turbines into the air. The effectiveness of airborne wind turbines is much higher than the land wind turbines. Therefore, we could expect many developments in this field. 

Offshore wind farms

Making offshore wind farms is a difficult task, but there are many advances in this field. Offshore wind turbines can be more independent and have larger efficiency. 

Microscopic wind turbines

Tiny wind turbines could be installed in gadgets and used to recharge the battery. You could put your phone near a window and the slow breeze will fill its batteries. You could also gently move it and create wind that will recharge the battery. This is especially useful when you are not able to charge your phone when you go camping or outdoors. 

Balloon wind turbines, kytoon wind turbines and other airborne wind turbines will soon fill our sky

Building wind turbines can be a difficult task. They need to be very tall and with a big diameter. The investment costs are very high and it is difficult to efficiently harvest wind energy. It is well known that in order to harvest wind power, you need to go up high in the sky. The winds are stronger and faster in upper layers of the atmosphere. Therefore, instead of building tall towers, we could easily put balloons, kites, kytoons, tethered airplanes and other devices with wind turbines into the air. Although there are still many difficulties that need to be solved, but scientists are developing suitable airborne structures that will withstand high speed winds and convert wind energy into electricity. Therefore,a kytoon, that is representing a hybrid between a kite and a balloon has been invented to overcome the difficulties that airborne wind turbines have. Kytoons  are relatively stable on high altitudes and they can be used to harvest wind power. Balloon wind turbines will soon be available everywhere and people could even tie them to their houses and harvest the high value wind energy from the high layers of the atmosphere. 

Perovskites open new horizons and bring hope for efficient and economic solar power solutions

Silicon has been used in solar photovoltaic cells for a long time. But silicon is not perfect. Production costs are high, the cell lifetime is not long, degrading efficiency is notable during years. Therefore it is definitely necessary to propose new solutions and new materials that will give the necessary boost to solar energy production. Recently, perovskite solar cells came into focus of attention in many research circles. Perovskites are efficiently absorbing solar energy and they are very durable and can be used for a long period of time without signs of degradation. Scientists are now developing new methods to include perovskite solar cells in mass production. However, there are still many elements that must be considered before these cell find their application in practice. We could surely hope that highly efficient perovskite solar cells will replace the currently used silicon photovoltaic cells. 

The future trends in solar cells technology

Solar cells technology requires innovations in order to meet the increasing demands of the market for renewable energy. The traditional photovoltaic cells have many disadvantages, such as high price, low efficiency, decreasing of efficiency with time, fragility and inconvenient installation. Therefore it is necessary to make new innovations in solar technology that will bring higher efficiency and easier usage of solar power. 

Some of the most important innovations in solar technology include perovskite solar cells, plasmoelectric solar cells, spray on solar cells and transparent solar cells. 

Perovskites 

Perovskites are special types of minerals that have strong benefits in solar power harvesting. Perovskite can be used as absorber in solar cells. It can be easily combined with photovoltaic solar cells to increase their effectiveness. Perovskites still have a long way to go, since their application is still in experimental phase. But it is obvious that the efficiency of perovskite solar cells is gradually increasing with new innovations and experiments. 

Plasmoelectric solar cells

Plasmoelectric effect is related to plasmonic effect on metallic surface where potential is created as a result of light that reaches the nanoplasmonic clusters. Plasmoelectric cells will bring boost to harvesting of solar powers in high range, including infrared part of solar spectrum. 

Spray on solar cells

Spray on solar cells combine perovskites and photovoltaic effect in an easy spray on application. This is very interesting because you don't need to build solar panels and you can just spray the solar cells directly on any desired surface. You could imagine how it would be easy to spray solar cells on roofs, walls and other parts of the building and make the building energy sustainable. 

Transparent solar cells

Instead of traditional dark gray or black photovoltaic solar cells, the future solar cells should be transparent. It is well known that black is absorbing the visible part of solar radiation. But the technology with organic molecules will give alternative to classical photovoltaic cells. The transparent solar panels will absorb both ultraviolet and infrared part of the solar spectrum and the efficiency will be satisfactory. We could surely expect that the transparent solar panels will replace the traditional windows and generate electricity for many buildings.
