This heat retention solar oven works like a greenhouse, allowing sunlight to pass into the pyrex bowl while also retaining heat. Inside the bowl an absorption container filled with dark-colored rocks will act as a heat sink that absorbs sunlight and will heat food placed on top of it. The rocks soaked up heat during the day and then released it on demand. The container is an aluminium plate containing holes arranged in a circular array to allow air to pass through. There are only three contact points between the container and the bowl. The reflector foil reflects the light directly into the bottom of the container.

Key Features:

- Low Tech and Low Cost.This solar oven can easily ...

The high speed (high RPM) wind turbine is designed to be used in vehicles with forward motion that produce air drag. The goal of this turbine is to capture the air that would normally pass through unused space in a vehicle.

The main uses for this design would in the automotive industry, however,the design could be used in a number of other battery run vehicles. Electric cars have the potential to greatly shape our future and reduce our carbon footprint but their limitations in distance causes consumers to second guess this as a viable option. These turbines would act to spin an electric generator that would be able to provide extra charge to the battery while driving. This added ...

Air resistance is the biggest obstacle to achieving high speeds. My method is based on the fact that the wagon is in the tailwind. The air is transported as fast as the carriage travels. The carriage travels in a rectangular channel. (It can be round but then you get less load space.) Suppose that its gable is 1 m2. The wagon rests on a low friction material. Required force to move= 3 Newton or 3 Pa.

What demands energy is the transportation of air. In one channel there is a pressing fan behind the trolley and in front of a suction. The pressurized fan takes air from a channel running parallel to the aforementioned. Black figure shows carriage. Red ...

The HiLLo-ORC (HERO Organic Rankine Cycle) system being developed at Industrial Technology Research Institute (ITRI) is a high efficiency, low temperature and low cost technology that enables the conversion of waste heat water or air to electricity. The innovation claim of the HiLLo-ORC system design derives from the concurrent optimization of semi-hermetic expander and systematic streams. In the HiLLo-ORC design, the semi-hermetic expander encloses a generator with a specially designed turbine-rotor that enable highly efficient working of the refrigerant evaporated by the waste heat into the expander. The refrigerant flows through the shell outside the rods flowing waste heat water or air in the evaporator. It can be evaporated at a very low temperature ...

Modern Fusion Reactor designs like the Wendelstein 7X utilize magnetic fields that are so complex that it took 19 years just to manufacture the hardware necessary to have them running. Having a reactor which utilizes a system of Holographic lasers which would augment existing “simple” reactor designs could speed up both the experimental process, as well as the developmental process of fusion reactor design.

Universities are already utilizing technologies like machine learning to help optimise reactor design and control, so if a high-power holographic laser were introduced, into existing reactor systems:
1. More discoveries of plasma phenomena could be made.
2. Less lead-time between experiments, as changes in variables could be done in software instead of hardware.
3. Anything ...

There have been many incidents where hurricanes destroyed many homes and killed many people. It happens frequently. I have thought of a plan how we can prevent hurricanes. In this concept, we will first build a right triangle by solid iron frames size 30 in.x 20 in.,height 100 feet. The length depends on the places 10 miles or 20 miles, etc., since the wall is made out of a solid iron frame. It will be 20 feet under ground for stabilization. Inside the right triangle solid iron frame there will be aluminum grid fence panels size 20 ft x 20 ft. That are each 1 in.x 1 in. The spaces in between them are also 1 in. We can ...

Hydrogen Electric Agricultural Utility Vehicle with Active Suspension

Design of a safer, renewable energy utility vehicle for the rural sector.
Note: this design targets the social, economic and environmental aspects of sustainability.

What problem does your design idea solve?
In New Zealand, agriculture is second only to forestry in the number of workplace fatalities each year, with farm vehicles in general and Quad Bikes, in particular, proving problematic.

Four-wheeled motorbikes, commonly known as Quad Bikes or All-Terrain Vehicles (ATV’s) have a long history of use in the New Zealand agriculture sector, where there are approximately 100,000 Quad Bikes in use.

Researchers estimate that 35 farmers come off their Quad Bikes every day; nine of them are hurt badly enough ...

INTRODUCTION:
IMAGNO - the word stands for imaginary engine that relates with magnet. Yes! as per its name, it is my imaginary idea which involves magnet to make a hybrid engine. It is type of engine which is combination of internal combustion engine and magnetic repulsion piston engine. A single car generates half a ton of CO2. The automobile industry is setting some strict environmental regulation in order to reduce these harmful emissions and keep the environment cleaner. The great thing is that the companies have responded to this regulation in a very positive way by introducing hybrid cars.

Existing hybrid cars have both electric motor and a gasoline-powered engine. But my thought is to design and construct a ...

Subscription and gentleman farms are all the rage. People want grass fed beef. Sometimes there isn't enough feed or grass available for rotations. It's gets muddy which leads to pests and maybe antibiotic overuse. Why can't a small or robo combine scoop up 100's or 1000's of nearby lawn grass to feed these chickens and cows and other farm animals. At 2.00 a large bale, these feed store could be home or farm pelletized and or wrapped in shrink plastic and exported even. There is a fuel amount there too. Grasses and turf of any genetic new or old background could be planted for whatever characteristic. Rye ...wheat lawns? Maybe not? As populations increase and land decreases we might ...

Invasive mussel infestations pose significant logistical and economic challenges for local communities, recreationists, and water managers. Currently, no specific remediation method has demonstrated to be both efficient and economical making it ideal for use in large-scale eradication of invasive dreissenid mussel populations once these become widely established in “open water”, e.g., lakes, rivers, and reservoir benthic zones. Infestations now encompass as many as twenty nine states and efforts to use aqueous-based biocides deployed in open water have not been demonstrated capable of delivering sufficient quantities of necrotic agent to the areas where target species settle and propagate (in the benthic zone).
