The presentation proposes a grand plan to provide 100% of US electricity from solar power by 2050. It details a visionary plan to build 3000 utility-scale solar power plants across deserts in the Southwest US, including a proposed 340MW solar plant in the Mohave Desert, to replace coal and gas. The plan estimates it would cost $2-6 trillion but save $400 billion annually and cut carbon emissions by 80%. It analyzes the potential locations, technologies, costs, schedules and partnerships required to implement a solar power network on this scale.

This presentation gives a quick perspective on costs that are involved in executing a MW scale power project in the Indian context. Both the indicative costs and the cost split-up among the various BOQ items are laid out at the various project scales. Indicative costs are assumed from a pure EPC perspective. However, generally the EPC scopes of work are sliced and diced and further outsourced/subcontracted. In such a scenario the execution costs might increase from the indicated costs.

A solar tree is a decorative means of producing solar energy and also electricity. It uses multiple no of solar panels which forms the shape of a tree. The panels are arranged in a tree fashion in a tall tower/pole.
TREE stands for
T= TREE GENERATING
R=RENEWABLE
E=ENERGY and
E=ELECTRICITY
This is like a tree in structure and the panels are like leaves of the tree which produces energy.
A Delay of a single day for a 10 MW plant can lead to a loss of Rs. 6.5 Lacs ($110,000) in addition to Statutory Losses. Here, we explore typical project execution timelines and possible reasons for delay. The presentation talks about Lead Times of Equipment, Key vendors, Permits Required, Construction & Engineering related delays and finally, gives recommendations on how to keep project on track.

Wind Turbine Power
• The amount of power generated by a turbine depends on the power in
the wind and the efficiency of the turbine:
• Power in wind
• Efficiency or Power Coefficient, Cp:
– Rotor (Conversion of wind power to mechanical power)
– Gearbox (Change in rpm)
– Generator & Inverter (Conversion of mechanical power to electrical power)

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.

"Impact of front-end architecture on development cost", Viktor TurskyiFwdays
I have heard many times that architecture is not important for the front-end. Also, many times I have seen how developers implement features on the front-end just following the standard rules for a framework and think that this is enough to successfully launch the project, and then the project fails. How to prevent this and what approach to choose? I have launched dozens of complex projects and during the talk we will analyze which approaches have worked for me and which have not.
