Green Options

On Wednesday, June 10, astronaut Maurizo Cheli set a world record while piloting the fully electric SkySpark. During an eight-minute flight at the World Air Games 2009 in Turin, Italy, he hit a top speed of 155 mph (250 km/h).

That’s a record speed for a 100-percent electrically powered aircraft.

Achieving a goal of 100 percent energy independence is a little closer for San Jose thanks to a momentous move by the City Council today. The City Council authorized the City Manager to negotiate and execute a Memorandum of Understanding (MOU) to develop potential lease terms and guidelines for developing an organics-to energy bio-gas facility.

Is 120 miles-per-gallon too much to ask from an American car company? Ford doesn’t think so.

With the addition of the Ford Escape Plug-In Hybrid (PHEV) to its development line, Ford Motor Company is showing that it can dance with the best of them.

The Ford Escape Plug-In Hybrid uses high voltage lithium-ion batteries, which can be charged using common household currents (120v). Fully charging the battery takes six to eight hours. For the first 30 miles following a full charge, the Ford Escape PHEV can drive on the batteries alone, before switching to operate as a fuel efficient, standard Ford Escape Hybrid. The transition is automatic and unnoticeable.

It was the Ford Escape PHEV that was delivered to Hydro-Québec, Canada’s largest electricity generator, on June 9th. Ford Motor Company and Hydro-Québec announced that Hydro-Québec has joined a North America-wide demonstration and research program on plug-in hybrid electric vehicles (PHEVs).

As part of its National Action Plan on Climate Change, India plans to give out $100 billion as subsidies to speed up solar energy production over the next 20 years.

Greenpeace calculates that the exploitation of less than 1% of the total solar thermal potential of the sun would be enough to stabilise the world climate through massive carbon dioxide reductions. Some large scale technologies must become viable to even approach this level.

One’s first thought on solar energy is often the photo voltaic systems (PV) that convert sunlight directly into electricity. These small systems seem to have real potential, especially in areas that lack grid based electricity. However, PV material is expensive and has, to date, not found application as a mainstream alternate energy source.

A new method of harvesting wave energy, the Irish Tube Compressor, is under development by the Dublin company JOSPA, which hopes to demonstrate superior performance in sustainable electricity production with their device.

Solar photovoltaics (PV) in the UK will be as cheap as grid-sourced fossil fuels much sooner than expected, a new study by Solarcentury finds.

For homeowners, PV will cross the “grid parity” mark in 2013. For commercial customers, it will occur around 2018. The magical parity date for PV is generally assumed to be 2020 in the UK. Says Solarcentury:

“The proximity to parity heralds the prospect of PV being a compelling investment for the individual, without subsidy, in only a few years time.”

The 14-page report by the UK’s largest solar firm is described as the most “up-to-date and accurate analysis on the investment case for PV in the UK.”

Its main point is that solar PV has precisely what it takes to move beyond a British niche and into the energy mainstream: Its energy potential is massive. It’s getting cheaper all the time. And it’s fast-approaching the holy grail of the solar sector, grid parity.

Time to tap it.

An unlikely savior may be coming to the rescue of the planet’s beleaguered coral reefs: Chris Olson, the founder and inventor of Swell Fuel wave powered electricity generators.  Olson has been building and testing small-scale floatable energy converters for a number of years, and they may prove ideal providers of the the low-voltage charge that seems to help coral reefs regenerate.

Chinese workers making energy-saving fluorescent lightbulbs for Western consumers have been sickened by the hundreds due to mercury poisoning.

While poor factory conditions in China shoulder most of the blame, the news does raise serious questions about just how “green” the mercury-rich fluorescent lightbulbs actually are.

Only a few years ago Jatropha was considered to be the wonder biodiesel feedstock suitable for production by small scale farmers in poor soils and arid countries. It has not lived up to the hype and it will be years before it can compete agronomically with soya and it is not scalable to the refining industry’s needs under small scale farming. Small scale rural farmers are more easily integrated into Jatropha based electrification in underdeveloped rural areas.

The Jatropha Spin

Jatropha curcas, also known as the Physic nut, is a perennial poisonous shrub. It is an uncultivated non-food wild-species that grows easily in hedges and scattered around homesteads.  It was spread from Central America to Africa by Portuguese traders who introduced it as a hedge material and a source of oil for light.

Wednesday, Canadian Environment Minister Jim Prentice announced his government’s most recent plan for eliminating CO2 emissions. The Canadian government hopes to phase out electrical generation by modern coal technology in favor of carbon capture and storage (CCS) – the much debated and as yet unproven “clean coal” concept – nuclear power, and other, renewable sources of energy.
