Solar panels are generally fixed and their optimal collection is limited due to collection angle.
Cloudy days traditional solar panels are inefficient in collecting sunlight
Solar panels take up a large amount of space.
Most solar panels are fixed direction, the beta.ray can rotate according to the sun direction, maintaining optimal collection angle – the small sphere, 75% smaller than a panel that collects the same amount of energy.
Cloudy days the beta.ray can improve efficiency by 50% due to concentration of sunlight.
The beta.ray is small and can be placed on any flat surface.
The spherical shape of the solar collector, together with an integrated solar tracking system, cover far smaller surface area than solar panels of equal efficiency, and allow a collection of energy, even if the light is very low
Machine learning has a big potential in the supply chain and distribution of food products in developing countries. Beyond just creating healither foods, the technology can be merged with weather data to improve distribution of non-perishable foods.
Overfishing is a global issue that causes environmental and social problems. From an environment standpoint, it not only affects fish stocks around the world which are declining at an alarming rate but also represent an important source of water pollution due to massive fishing boats deployed in various locations. Those big scale exploitations then affect small scale fishermen by decreasing the amounts of fish reaching the coasts. Also, a lot of fish caught by the bigger boats are exported, leaving local population with a reduced quantity of food available.
One of the drivers of overfishing is the need for small fish used as feed (usually for bigger fish productions and livestock). As the Fast Company’s article mentions : “NovoNutrients wants to replace that fish food with something more sustainable: microbes grown with carbon dioxide”.
The company uses carbon dioxide to feed microbes that become protein used for animal feed production. A pipe is connected to water where the gases are dissolved.
During the process, Hydrogen is also being produced thru (solar-powered) hydrolyse which helps power the installation.
This technology is interesting as it could help cities with diseases spreading among trees. By mapping the type of trees available around the city, officials would be able to better diversify the kind of new trees planted making “greening” efforts more efficient.
1)Energy & Waste: The aircraft industry contributes to 9% of the total CO2 emissions among the transportation sector in the United States. These emissions are expected to triple by 2050 without the establishment of policy regulations. Ultimately, alternative sources energy and a transition away from harmful pollutants into the atmosphere need to be developed to align environmental concerns with transportation demands. As such, Solar Impulse has developed to fully solar power aircraft to tackle the issue.
The project took 12 years of research and development to come to fruition, resulting in a 2.3 ton aircraft with over 17,000 solar cells (23% energy efficient) that were each tested 3 times
The PV cells are protected from UV radiation with a polymer film and many of the components are made with carbon fiber and alveolate foam in a honey comb structure
It consists of multiple lightweight characteristics such as led lights and structural components, solar cells, energy dense batteries, energy efficient electric motors (97% efficient), and thermal insulation
The aircraft has the capacity for only one pilot at a time and is composed of an unheated and unpressurized cockpit measuring 3.8 cubic meters

In this piece, they are attempting to train crows in the Netherlands to pick up cigarette filters from the streets in order to keep them clean. However, if successful, it could potentially be applied to any other material, like plastic bags and so on.
Cleanliness on streets and segregating it for re purposing. With growing cities and population sizes, its an issue being faced by almost every large city in the world today.
In the Netherlands alone, over 6 Billion cigarette filters are thrown around the country. Cigarette filters are made up majorly of fibers which clog sewage systems and do not easily decompose.
Inspired by a TED talk which demonstrated how crows can be trained to connect coins in exchange for food, they decided to apply this principle to clean up cigarette filters. The founders of ‘Crowded Cities’ based in the Netherlands have designed a product called the Crowbar, which essentially delivers some food to a crow once it drops a cigarette filters which is verified by a computerised source with a camera.
First the crows pick it up and drop it in the funnel shaped container below.
The item is recognised with a camera and if its a cigarette filter, the device spits out crow food.
It is their hope that the crow shares his/her experience with others and feed themselves by word of mouth.

Department of Sanitation, or its equivalent
Although they are yet to put out the product ‘Crowbar’ in the field, they are current testing out their design and optimising it.
Building partnerships with the city and recycling centres would be valuable once the device is placed on ground.
As I mentioned earlier, this is an innovative application that can be useful for a variety of items beyond cigarette filters. It is utilising the learning capabilities of crows within a simple reward system and suitable technology.
1)Water and Health: There are areas around the world with limited access to natural water resources but with considerable proximity to fog. This is where fog harvesting can come into play but capturing fog and producing useful water because without water, people cannot survive.
Dar Si Hamad has established a 600 square meter installation in Morocco, becoming the largest fog harvesting site
MIT was able to develop material that could produce 5 times more water with a mesh made from stainless steel filaments
The mesh is dip-coated, causing droplets to flow down to a water basin quickly rather than getting lost back to the environment

Comments to Off grid solar powered water device – Zero Mass Water by JV2610
A unit with one solar panel, the company says, can produce two to five liters of liquid a day, which is stored in a 30-liter reservoir that adds calcium and magnesium for health and taste. This seems very energy efficient and seems to be able to store a pretty good amount. The addition of electrolytes is even more interesting and beneficial for health.
There exists a need for artificial muscles that are silent, soft, and compliant, with performance characteristics similar to those of skeletal muscle, enabling people to overcome their disabilities. Different types of electric motors or pneumatic systems drive exoskeletons, prosthetic and assistive devices to enhance human performance or aid disabled people to walk and carry out everyday tasks. They provide fast responses but are bulky, heavy, stiff, noisy, non-biological in feeling, and as such less accepted by the end user.
Textile processing permits scalable and rational production of wearable artificial muscles, and enables novel ways to design assistive devices.
Swedish researchers have created actuators (An actuatoris a type of motor that is responsible for moving or controlling a mechanism or system)— from cellulose yarn coated with a polymer that reacts to electricity. These fibers are then woven and knitted using standard industrial machines and coated with conducting polymers using a metal-free deposition. The researchers have called these textile actuators, “textuators”.
These textuators scale up force by parallel assembly of single fibers (Fig A), amplify the strain by using stretchable patterns ( B), and can be effectively mass fabricated. This will allow for a new means of driving and designing assistive devices, such as exoskeleton-like suits with integrated wearable actuators.
Hospitals, NGOs caring for disabled people, People with temporary or permanent disabilities, Elderly people, Prosthetic industry, Physiotherapists, People recovering from injuries etc.
Knitting and weaving artificial muscles could help create soft exoskeletons that people with disabilities could wear under their clothes to help them walk. By varying the processing method and the weaving pattern, it should be possible to tailor the force and strain characteristics of a textuator to the specific application at hand.
