Short Change: The Vampire in your Living Room

Printers, microwaves, chargers, DVD players, desktop computers and many other devices all drain energy when turned off or not in use. This drain is known as ‘vampire’ or ‘standby’ power and is responsible for a huge amount of energy loss each year. Since that energy is largely generated by burning fossil fuels, vampire power accelerates the rate of global warming as well as raising your electricity bill.


A Salt and Battery: How to Store Sunlight

It has become common knowledge that humanity needs to change the sources of our energy at an unprecedented rate if we are to avoid the worst effects of climate change. Renewable energy systems are the most promising means available to reduce our impact on the earth without giving up the comforts of readily available electricity. However, an issue with some renewables like wind and solar is that the energy is only available sometimes. There is no solar power without sunlight and no wind power without wind. In this article I’ll be looking at a type of solar power plant which avoids this problem in a most ingenious way.

Shock Wave: Electricity From The Ocean

Some renewable technologies harness the vast mechanical power available from a planet that is in constant motion. Wave power generators (WPGs) are a possible energy source of the future, but how do they compare with their rivals?

Win Win Win Win: The Magic Science of Plasma Waste Converters

Humans have an incredibly extensive waste problem. Right now, most of that waste is sent to landfills where it takes up space for thousands of years, leaching harmful chemicals and gases into the soil and atmosphere. Alternatively, we send our waste to incinerators which burn it for energy, but which release harmful greenhouse gases (GHGs) and toxic by-products in the process. A large proportion of our plastic waste ends up in the ocean, where it strangles and poisons fish, seabirds and marine mammals. What if I told you that there was a way to get rid of almost any type of waste in one machine, that the machine would release no harmful chemicals or GHGs, and that the process would produce useful by-products and excess energy that could be sold back to the grid? Such a machine exists right now; the plasma waste converter (PWC).
