This research emphasizes the flax-based composite, developed using the hand lay-up method and augmented with three distinct graphene nanofillers. The graphene fillers are categorized as large nanorods (dimensions 3-5 nm, lengths 150-300 nm), small nano threads (dimensions 6-12 nm, lengths under 50 nm), and spherical particulates (dimensions 29-39 nm). ...Thermal conductivity evaluations of the composite, integrated with different graphene configurations, recorded enhancements ranging from 0.22 W/mK to 0.286 W/mK at a 2 wt.% graphene concentration. At an elevated 4 wt.% graphene addition, the small rod-shaped fillers demonstrated an impressive 59.6% enhancement over the flax/epoxy baseline, while the larger rod and spherical graphene nanoparticles showcased a 22.14% enhancement. ....% inclusion of spherical graphene nanoparticles is particularly effective in enhancing the ultimate tensile strength and fracture elongation of the epoxy matrix, registering improvements of 10% and 29% respectively.

Solar Energy Harvesting: How to Generate Thermal and Electric Power Simultaneously describes energy harvesting using a hybrid concentrating photovoltaic (PV) system with simultaneous thermal generation for energy storage. Several designs have been proposed to build a system that takes advantage of the entire solar spectrum through direct electric generation using concentrated light onto photovoltaics while generating thermal energy using wavelengths of light not captured by the PV cell. This title addresses the current technologies and state-of-the-art designs, as well as the methodologies, underlying physics, and engineering implications.

E-cars are oversupplied and changing in all respects but in this frenzy of birth and death the future is being created with hybrid cars rapidly gaining market share. The sales of pure electric cars are likely to take off in the second half of the coming decade as certain technical and cost challenges are resolved. Toyota and Tesla have hugely benefitted from correct market positioning. Yet, Toyota is now betting strongly on fuel- cell hybrids, and Tesla on mainstream pure electric cars. A vicious shakeout of car and battery manufacturers has commenced with the winners expecting a handsome pay-off. IDTechEx finds that the global sales of hybrid and pure electric cars will triple to $178.9 billion in 2024 as they are transformed. For example, components are becoming integrated; the range extender, as an optional extra, breaks down the difference between pure electric and hybrid. Car manufacturers vertically integrate and collaborate, competing with their suppliers.

This master report summarizing and forecasting every sector of the EV industry remains unique. It adds new sectors as they become substantial, the latest being car-like micro-EVs homologated as quadricycles in Europe. Many profitable niches are emerging just as the largest major sectors are changing in importance; the industrial and commercial sector is now bigger and much more profitable than e-cars, and is set to remain so for at least eight more years. All components are changing with supercapacitors sometimes replacing or partly replacing batteries and also new types of battery, energy harvesting, power electronics and structure powering growth. Disruptive change is now the norm and the fruits of all this are truly spectacular; including such things as the Marian fast- surface boat that acts as a submarine when necessary, the fixed-wing plane that will stay aloft for five years on sunshine and the flying jet ski.

Larger airframes drove the development of electrical systems, capable of quickly and reliably starting the new higher power engines. These soon gave rise to the need for engine-mounted electrical generators as the primary source of in-flight power for the electrical loads and onboard recharging of the aircraft battery system. Of all the backup power sources, batteries represent the most common means of storing energy for auxiliary or emergency power requirements. It is not unusual for a typical commercial airliner, such as a B-737 or A-320, to have dozens of batteries on board. Over time, multiple battery chemistries were put to the test and the industry is still working on the optimal option. The lithium-ion technology has been gaining acceptance, with some important aspects to be considered: the application type, basic safety requirements and the presence or absence of humans on the vehicle.
