The city has an extensive system of street light poles. They are connected to the electric grid all the time. Figure out how else it is possible to use this network of poles with connected electricity.
For safety and comfort, the street lights are often turned on full power when no people are on the streets - think of a way for the city to be aware of the number of people in a particular location and safely adjust the street lights' power to their presence. What other city services use resources irrationally relative to people's needs, and how can this problem be solved?
There are solutions for installing solar panels and batteries to them. Such solutions are pretty expensive for one family. Let's imagine we have several families living in the same yard/home/townhouse, suggest they collectively install a solar kit. What might such a sharing solution look like? Let's add to such a solution also the sharing of the electric car.
Propose a hard/software solution for anonymous evaluation of the performance of city subsystems: heating, lighting, cleaning, etc. The goal is to have an independent instrument of the assessment to influence the quality of city services. How to create an instrument as objective as possible? Meritocracy?
In the construction of buildings or highly loaded structures (e.g., bridges or interchanges), there is a problem of monitoring the internal quality of the construction over time, in 10–20 years. Let's assume that we have a technology of low-speed data transmission over a long distance, minimal energy consumption, and a micro battery with a number of charge-discharge cycles of 10000 pcs before partial degradation. How can we create a device for monitoring the parameters of constructions for 20 years?
Smart home for the average person is complicated to control and expensive to install. There is still the problem of incompatibility between control protocols from different manufacturers. What solution could be simpler and cheaper to control and monitor electrical devices in the house?
The issue with tracking parking in paid parking areas was already solved in the city 10 years ago with a magnetic field sensor placed in the parking space.
The problem is that the sensor needs to be installed in each parking space, and it is still necessary to check violators. How to solve this problem and create an innovative solution? Technological development in 10 years will allow us to track the car itself and pay for parking automatically.
The average small house consumes about 10kW of energy per day. The battery of an electric car has a capacity of 60kW or more. It means that every day near our house, we have a backup battery capable of fully powering the house for several days. Suggest solutions that will help owners of electric cars reduce electricity costs.
In old houses/apartments, there is a connected electricity network. As a rule, it has a limited capacity of 10–15 kW. At the same time, the amount of powerful electric equipment increases, such as heat pumps or electric car charging. What solution can help not exceed the connected power limit and still use modern equipment?
*Note: upgrading the connected power or increasing it are too expensive and not always possible.
The second version of this problem – same story downtown – imagine old wiring. How to install a powerful charging station there?
The development of solar energy requires the development of energy storage. Today's basic design of new storage facilities is based on lithium-ion battery technology. At the same time, the most common technology in the world is hydro-storage facilities – they are the cheapest but require landscape features. What can other technical solutions allow storing energy cheaply and for a long time?
In industries with a lot of manual labour (and no robots yet), there is a problem of personnel fatigue during a shift, when in the last hours of the shift, a person starts making a lot of mistakes – picking up the wrong tool or the wrong material.
Develop a technical solution to help people work when their attention span is reduced.
