On Thursday March 18, the 2010 World Energy Technology Summit will convene in New York city. The summit will explore technologies that can help save the planet and shape the future. Some of the world’s brightest minds and innovators in energy-tech will…

Fluxxlab has an idea to harness the "energy" in revolving doors. Already an energy saver compared to traditional doors in office buildings … these could generate significsant power in large building with hundreds of workers.

" … work to date has been focused on sustainable energy harvesting, specifically in the form of converting small amounts of human energy into electricity …"

"… Revolution Door is a modified revolving … a redesigned central core replacing that of any existing or new revolving door, a mechanical/electrical system that harnesses human energy and redistributes electricity to an output, and an output device that maps the harnessed energy … the Revolution Door will directly communicate a single person’s contribution to an energy cycle possible through the metabolic relationship between people, technology, and architecture."

Study looks at the impact of new energy project on land use and nature in the United States. Biofuels have the highest land area impact, while nuclear has the lowest. Over 200,000 square kilometers of new land is likely to be needed to meet US energy demands by 2030. Of couse, energy conservation strategies can reduce these requirements. …

… “Nuclear power (1.9–2.8 km2/TW hr/yr), coal (2.5–17.0 km2/TW hr/yr) and geothermal (1.0–13.9 km2/TW hr/yr) are the most compact by this metric. Conversely, biofuels (e.g., for corn ethanol 320–375 km2/TW hr/yr) and biomass burning of energy crops for electricity (433–654 km2/TW hr/yr) take the most space per unit power. Most renewable energy production techniques, like wind and solar power, have intermediate values of this metric. ” …

The small German town of Dardesheim (fewer than 1,000) and neighbors in Halberstadt in what was East Germany "… want to become 100% renewable using solar, wind, and biomass."

" … Four pioneering wind turbines were installed in the mid-1990s, collectively producing one million kWh per year …"

"In 2006 they developed a 62 MW wind project comprising 28 Enercon E70s and one E112, a giant 6 MW turbine … wind turbines will generate from 120 to 130 million kWh annually, enough to meet the needs of nearly all the 80,000 residents of the county."

" … also installed nine different solar PV plants … During their first year of operation the combined 380 kW of solar PV generated nearly 250,000 kWh, about one-third of the Dardesheim’s domestic electricity consumption."

Gainesville Florida has been active in alternative energy since 1997 offering rebates for solar water heating and now for solar PV.  They are now looking to increase the amount of PV electricity generated by offering more incentives.

 " …offered solar water heating rebates since 1997 and solar photovoltaic (PV) systems rebates since 2007 … now … created a solar feed-in-tariff (FIT) program to increase the number of solar PV systems in Gainesville."

" … May 2009, … approved a 30-year contract between GRU and Gainesville Renewable Energy Center … build, own and operate a 100-megawatt biomass power plant … fueled by forestry-waste material generated by … paper pulp, chip and saw timber – as well as urban wood waste. "

" … using biomass … will promote our energy independence, add diversity to our fuel supply and shield customers from anticipated increasing fossil-fuel prices. … allow Gainesville to achieve its carbon-reduction goals, which are based on the Kyoto Protocol."

" … plan to purchase energy that G2 Energy, … generate from methane gas collected at the Marion County Baseline Landfill … "

Imaging a cell phone that is self powering … ?

Nokia has something in the works that might just achieve that goal though it is a ew years off and not likely to be scalable for largeer appliances ,,, but you never know whaqt advances in technology might bring …

… "…a cell phone that recharges itself … harvests ambient radio waves from the air, and turns that energy into usable power. Enough, at least, to keep a cell phone from running out of juice.

" … ambient electromagnetic energy is never going to … power your whole house or office, but it just might be enough to keep a cell phone alive … enough to slowly recharge the cell phone battery while it’s in standby mode, theoretically offering infinite power …"
