Inventions with power to save you cash
When it's time to buy new appliances, be sure you choose energy efficient ones. A more efficient appliance will save you money in running costs - and you'll be doing the environment a good turn.
Ceiling fans
Fans are the most efficient way to keep cool in summer. They work by circulating air, which increases evaporation of sweat from your skin - they cool the person, not the room. Fans can also be effective in winter. A fan on reverse cycle will recirculate the rising warm air from the ceiling back down to where it's needed.
The Aerotron e503 is a new generation of ceiling fans. Its energy-efficient design outperforms every fan in its class, and leaves conventional fans for dead. Silent and sleek, the fan's efficiency is due to the blades' aerofoil shape and wingtips, an active self-balancing system, and a custom-built DC motor. RRP$389, including remote.

Home automation
Home automation used to be the preserve of the wealthy and the wired, but a new generation of easy to use, low-cost systems are making wireless control of appliances a practical reality for the average householder. They mean energy-efficient practices can be automated with push-button simplicity.
Belkin's WeMo Switch + Motion is a system that works with wireless technology, simple plug-in adaptors and motion sensors. You can connect it to any plug-in electronic device. If you connect an electric heater, for example, you can turn it off and on, set timers and adjust settings - all from a user-friendly interface on your iPhone or iPad.
The motion sensor can turn devices on when you enter a room, and off when you leave. WeMo can also be connected with services such as IFTTT (If This Then That; ifttt.com), so you could, for instance, program it to send a text when the temperature drops to below 15 degrees, and then turn on a heater. Ingenious. RRP$119.

Halogen replacements
Most homes renovated or built in the past three decades had halogen downlights installed, and plenty of them. With each halogen using on average 50 watts, the energy costs are significant.
Brightgreen's D700 dimmable halogen replacement bulb matches the brightness (720 lumens) of a 50 watt halogen with a 70,000-hour lifespan, while using a fifth of the energy. Brightgreen's calculator estimates a payback time of a year or less per bulb - after that it's all money in the bank. RRP$69.

Insulating blinds
Gap sealing, glazing and frame materials all play their part in mitigating heat loss and gain through windows, but window furnishings also play a critical role. Heavy lined curtains with pelmets provide the best insulating benefit, but if they're not your thing there are other options.
Duette Architella Opaque blinds are a new generation of "honeycomb" blinds designed to provide an air barrier against heat loss and gain. The "honeycomb" aesthetic is created by triple air pockets that trap insulating layers of air within the blinds. When the blinds are installed as fully recessed and reveal-mounted, the manufacturers claim they will almost halve heat loss. Price on application.

Ceiling fans are one of the most efficient ways to stay cool because they circulate air to increase evaporation of sweat rather than cooling the whole room. The Aerotron e503 is a new-generation ceiling fan that boosts efficiency with aerofoil-shaped blades, wingtips, an active self‑balancing system and a custom DC motor. It's designed to be quiet and use less energy than conventional fans (RRP $389), helping lower your summer cooling costs and even improving winter heating efficiency when run in reverse.
Belkin's WeMo Switch + Motion lets you wirelessly control plug‑in devices with simple adaptors and motion sensors. You can turn devices on/off, set timers and change settings from an iPhone or iPad. The motion sensor can automatically switch devices on when you enter a room and off when you leave, cutting wasted run time. WeMo also integrates with services like IFTTT to automate actions (for example, send a text when temperature drops below 15° and then turn a heater on). RRP $119.
Brightgreen's D700 matches the brightness of a 50W halogen (720 lumens) while using about a fifth of the energy and offering a 70,000‑hour lifespan. According to Brightgreen's calculator, the energy savings typically deliver a payback time of a year or less per bulb, after which ongoing savings reduce household lighting costs. RRP $69.
Duette Architella opaque blinds use a triple 'honeycomb' air‑pocket construction to trap insulating layers of air, creating an air barrier against heat loss and gain. When fully recessed and reveal‑mounted, the manufacturer claims these blinds will almost halve heat loss through windows, reducing heating and cooling demands. Pricing is on application.
Yes. Ceiling fans cool people in summer by circulating air, but they can also be effective in winter when set to reverse. Running a fan on reverse recirculates warm air that rises to the ceiling back down into the living space, improving the efficiency of your heating and potentially lowering heating costs.
Integration with IFTTT (If This Then That) expands automation possibilities by linking smart devices and services. For example, you can program a WeMo Switch to send a notification when the temperature falls below 15°, then automatically turn a heater on. These automated triggers and routines reduce manual intervention and help ensure appliances run only when needed, trimming energy use.
The article lists example retail prices: Aerotron e503 ceiling fan RRP $389, Belkin WeMo Switch + Motion RRP $119 and Brightgreen D700 replacement bulb RRP $69, while Duette Architella blinds are priced on application. Whether the upfront cost is justified depends on expected energy savings — Brightgreen estimates a payback of a year or less per bulb, and other products lower running costs through reduced energy use or smarter control, so many households recoup costs over time.
Choosing energy‑efficient appliances, lighting and window furnishings reduces ongoing running costs and can produce measurable payback (for example, Brightgreen's bulb). Home automation and insulating products automate efficiency and cut wasted energy, which improves household cash flow and can also have environmental benefits. For everyday investors, these practical upgrades can be a low‑risk way to protect disposable income and lower utility bills.
