Every other October since 1987, solar-powered cars have raced from Darwin to Adelaide, Australia, in the World Solar Challenge, an 2,900 km (1,800 mi) route that puts the latest alternative-energy technology to the test. The cars can run only on sunlight that their solar cells capture and convert to electricity. Electric motors that are at least 90% efficient are necessary. Racing teams are usually comprised of college students, and teams are backed by major aerospace and high-tech corporations. The eleventh race, held in 2011, was won by a Japanese team; a Netherlands team finished second, and the fast- est U.S. team, from the University of Michigan, finished third. Drivers had to avoid a bushfire, wallabies, cattle, sheep, lizards, and strong winds.1 Top speeds ranged from 143–154 km/hr (89–95 mph), and the average speed of the winning car was about 70 mph.
Suppose you decided to organize a team from your university, design and build a solar-powered car, and enter the race. Here’s the challenge: The roof of an automobile is just barely large enough to hold a solar panel that can gather enough energy to drive a car. It can’t power a regular sedan or SUV, and it can just barely power any car at all. How would you win? Should you build a car that, under the race rules, has the largest solar-powered area and tries to gather as much sunlight as possible, making the car as heavy as you can? Or would you opt for energy efficiency and build the lightest car, trading off a larger energy in- put for greater energy efficiency? Would you spend money and add weight to make the car’s shape as aerodynamic as possible, so that it would have the least resistance from the wind? And how about reliability? Would you build a stronger, therefore heavier car, or would you place your bet on the sleekest, lightest, car?
The car built by the Netherlands Nuon team, the Luna 6, had three wheels, a body made of carbon fiber, and solar panels covering nearly every inch of its top surface. The students who designed it tested a model in a wind tunnel
14.1 Outlook for energy
Energy Today and Tomorrow
The decisions we make today will affect energy use for generations. Should we choose complex, centralized en- ergy production methods, or simpler and widely dispersed
by covering it with oil; the oil activated an ultraviolet light used to highlight any impediments to its aerodynamic de- sign. The Luna 6 was 140 kg (308 lb), 20 kg (44 lb) lighter than the Luna 5 designed two years before.
The Tokai Challenger 2, also a three-wheeler, featured carbon monocoque construction on its top surface that incorporated a 6-m square array of silicon solar cells.
The Netherlands team lost out to the Tokai Challeng- er 2 largely because of the gains the Japanese team made on Day 3 of the four-and-a-half-day race, wrote British Diederik Kinds in The Register.2 He analyzed the ra ...

Renewable energy is generally electricity supplied from sources, such as wind power, solar power,
geothermal energy, hydro power and various forms of biomass. The popularity of renewable energy
has experienced a significant upsurge in recent times due to the exhaustion of conventional power
generation methods and increasing realization of its adverse effects on the environment. Wind energy
has been harnessed for centuries but it has only emerged as a major part of our energy solution quite
recently and this report focus on utilizing wind energy by using vertical axis wind turbine.

A Strategic Approach: GenAI in EducationPeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

2. There are several inventions that help to
clean air before factories release it back into
the atmosphere.
3. Baghouses
Power plants often use more than one device
to stop pollutants from escaping
smokestacks. Baghouses are filtration
structures such as the one seen here that
have been retrofitted to many power plants
nationwide. They work by catching fine
particulates—tiny clumps of soot, dirt, and
chemicals that can damage lungs and collect
in the atmosphere, creating smog.
Baghouses function as massive vacuum
cleaners. They are lined with many fabric
filter "bags," which plant engineers
periodically clean or replace, carting away
the particulates they collect.

4. Biodiesel
This relatively new type of alternative fuel is
processed from any vegetable oil—including
used oil from fast-food restaurants—and can
power most diesel-engine vehicles without
modification. Sales of biodiesel are gradually
increasing—75 million gallons were sold in
the U.S. in 2005—and many government
vehicles like these from the USDA use it to fill
up. Though it burns 78 percent cleaner than
petroleum diesel and comes from a
renewable source, it is double the cost and
fueling stations are scattered. Furthermore,
only a fraction of vehicles in the U.S. have
diesel engines, though new fuel-efficient
models on the market have recently gained
in popularity.

5. Bioreactors
While most antipollution technologies
involve massive, complex equipment, some
scientists are experimenting with tiny, simple
living organisms called cyanobacteria that eat
polluting carbon dioxide (CO2). These algae
can flourish in the blistering temperatures of
chimneys. Researchers have designed
"bioreactors," window-screen-like
membranes teeming with cyanobacteria, for
future installation into power plant
smokestacks. Fiber- optic cables would focus
life-sustaining light across the membranes,
allowing the algae to grow inside chimneys
while feasting on a diet of CO2 exhaust. This
technology has already proved itself in small-scale
demonstrations. A test on a fully
operational power plant is about five years
away, and scientists are also studying the
same algae as a potential source of hydrogen
energy.

6. NASA envisions clean
energy from algae
Massive algae blooms grow depending on
the amount of light they receive, the
temperature, and the amount of nutrients
available in the water.

7. Catalytic Converters
Most cars are sources of pollution, and to
keep up with emissions laws automakers
began refining car engines and fuel systems
in the 1970s. These modifications culminated
in catalytic converters, which treat exhaust
before it leaves a car's tailpipe, converting
toxic combustion by-products such as carbon
and nitrogen monoxides to less-toxic gases.
Catalytic converters have been highly
successful in reducing emissions, but
substantial increases in the distances cars
and trucks travel on average and in the
overall number of vehicles in use have made
up the difference, and cars are still a major
cause of pollution.

8. Ethanol
Ethanol is a clean-burning alcohol produced
by bacteria that ferment the sugars in corn
and cornstalks. Some environmentalists tout
ethanol as a potential alternative to gasoline.
In the U.S., about five million vehicles already
drive on "flex-fuel." They can use traditional
gas or E85, a mix of 85 percent ethanol and
15 percent gasoline. Converting an
automobile to flex-fuel is inexpensive, but
there are few ethanol pumps in the U.S. In
Brazil, nearly all cars run on a 96 percent
ethanol fuel produced from sugarcane, which
is readily available. Brazilians have seen
benefits: not only is it cleaner burning, it is
half the price of imported gasoline.

9. Nuclear Power
Nuclear power plants provide about 17
percent of the world's electricity and about
20 percent of the electricity in the U.S. They
are extremely clean compared to coal-fired
plants, which, perhaps surprisingly, release
more radioactivity than a properly
functioning nuclear power plant. Many
experts believe nuclear power such as that
being developed in this Sandia National
Laboratory experiment is an important
option for the U.S. and the world to meet
pollution-free energy needs. But others cite
significant problems with nuclear power. For
example, mining and purifying the uranium
that fuels nuclear plants is not a clean
process; improperly functioning nuclear
plants present environmental and terrorism
risks; spent nuclear fuel remains toxic for
centuries and must be stored; and
transporting nuclear fuel to and from plants
can be hazardous.
http://www.pbs.org/wgbh/nova/sun/clea-nf.html
10. Scrubbers
Since the Clean Air Act was passed by
Congress in 1990, electric generating power
plants in the USA have been required to use
industrial pollution control devices. Toxic
exhaust from power plants creates much of
our air pollution.
Many plants have already added scrubbers to
their chimneys. These industrial pollution
control devices can remove toxic substances
from exhaust streams, or neutralize them so
that they are harmless or even recyclable.
Ironically, the more robust the plume of
smoke rising from a smokestack, the more
likely it is scrubbed exhaust. So-called wet
scrubbers can increase the proportion of
water in waste gases, plumping up smoke
plumes.

11. Getting free
• So many of our modern conveniences depend on using coal and
petroleum, but we have many pollution problems that result in pollution of
air, water, and land.
• Some of the things that are being done to help get us free of the past fuels
are below.
12. Fuel Cell Cars
Imagine a car that only had one waste
product: water. That is the tantalizing
promise of fuel cell cars, which have not yet
arrived in the commercial marketplace. If it
sounds too good to be true, that's because it
might be. Fuel cell cars produce electricity by
chemically breaking down hydrogen fuel.
When pure hydrogen is used, the only by-product
is water, but pollution is produced in
creating the fuel itself. Also, because
hydrogen is a flammable gas, safety is an
issue. Fuel distribution stations, such as this
proposed northern California hydrogen
pump, and storage solutions are under
development but still rife with kinks. It could
be two or more decades before fuel cell cars
are widely available and adopted by drivers.

html
13. Hybrid Cars
Celebrity owners have made them famous,
and drivers' concerns about skyrocketing gas
prices and the environment have made them
a popular new choice. Sales in the U.S. of
hybrid cars such as Toyota's Prius, seen here,
doubled in January 2006 compared to the
year before, with nearly 16,000 cars sold.
Hybrids get their power from small gasoline
engines combined with electric motors and
rechargeable batteries. Their compact
engines deliver excellent gas mileage and
cause much less pollution than those in
conventional cars. Experts estimate that
driving a hybrid for 100,000 miles would
barely fill a teacup with pollutants.

14. Solar Power
The sunlight that reaches Earth's surface
delivers 10,000 times more energy than we
consume, and solar power aims to harness
this force. Solar technologies use sunlight to
provide heat, electricity, and even cooling for
homes, businesses, and industry by
conducting electrons across an array like the
one at right or like the tiny solar cell in your
calculator. Researchers have optimistically
proposed that if they could cover just 0.1
percent of the Earth's surface with highly
efficient solar cells they could in theory
replace all other forms of energy. At
universities around the world, efforts are
under way to develop the kinds of advanced
solar arrays using nanotechnology and other
cutting-edge science that could perhaps
accomplish this goal in the future.

16. Wind Energy
Wind is a renewable energy source that
emits no pollution. It is the fastest-growing
"green" energy in the U.S. and provides light
to the Statue of Liberty. Wind farms—
clusters of huge windmills—produce
electricity by using the motion of their blades
to spin a shaft connected to a generator.
Experts estimate that the electricity created
in 2006 by America's wind farms will displace
some 15 million tons of carbon dioxide. Over
five million acres of forest would be needed
to absorb that much CO2. Some people
oppose wind farms because they occupy
large tracts of land and can sometimes harm
birds, but most agree that their
environmental costs are much lower than
those of fossil fuels.
