Singapore’s Solar-Powered Supertrees

A report on Singapore’s supertrees:

“It’s pretty innovative stuff. The structures mimic the ecological functions of real trees through their environmentally sustainable features. Some have photovoltaic cells on their canopies to harvest solar energy to light up at night, others are integrated with cooled conservatories and serve as air exhaust receptacles.”

Dragonfly-inspired turbine harvests energy from slow-moving winds

Renzo Piano just unveiled a dragonfly-inspired turbine that specialises in harvesting energy from slow-moving winds!

As we shift away from fossil fuels, many utilities have focused on building the biggest and most powerful wind turbines possible to meet growing energy needs. Architect Renzo Piano has taken a different approach, however, focusing his efforts on a compact, yet super-efficient wind turbine that anyone can erect in their backyard. Called the “Dragonfly Invisible Wind Turbine” the two-blade design mimics the delicate dragonfly’s ability to float on the slightest of breezes. Based on the physics of dragonfly flight, Piano’s mini-turbine can harvest energy from winds that blow as slow as four miles an hour.

The Vertical Farm: Feeding the World in the 21st Century

Dick Despommier has just released his exciting new book on vertical farms.

“Dr. Dickson Despommier is considered one of the world’s foremost experts on vertical farms – a theoretical concept that may offer the panacea to our food production problems in the future. Supporters and critic of this concept abound, with fans proudly touting the benefits of towering botanical skyscrapers and naysayers concerned with how vertical farming could be misused, poorly executed and could rack up extreme costs.”

Can LED Bulbs Make Nuclear Plants Obsolete?

A recent article that poses an interesting question, Blubs Vs Reactors?

“By a sheer coincidence, LED lights and nuclear power provide an intriguing way to study the issue. Nuclear power plants generate approximately 19% of the electric power in the U.S. Lighting accounts for approximately 19% of the power used.  Thus, you can argue the fleet of 104 commercial nuclear reactors exists to keep the lights on. If you want to increase functional capacity by 20 percent, you can build 21 nuclear reactors or reduce light power by 20 percent.”
