ABSTRACT
A new ultracapacitor technology from APCT (US-Ukrainian start-up) provides an efficient, low cost means of managing power delivery for applications ranging from hand held devices to hybrid vehicles and power generating systems of all types. When integrated into battery powered devices, the APCT technology can extend battery life by as much as 400%, lowering the cost of batteries and reducing hazardous waste streams. Fast charge/discharge cycling with 95% efficiency improves performance and lowers cost for fuel cell vehicles and hybrid electric automobiles. High energy density and hundreds of thousands of cycles provides critical load leveling…

Emerging Energies Technology Summit 2007: Renewable Energy

Posted by who am I On December - 30 - 2008

This conference on Emerging Energies Technologies takes an unbiased look at how the United States can make the transition from dependency on carbon-based fuels to a sustainable alternative fuels-based future. In this program Nobel laureate Alan Heeger of UCSB and Joan Ogden of UC Davis give their perspectives on renewable energy.

Bangladesh – Renewable Technology Opportunities for Women

Posted by who am I On December - 30 - 2008

Opportunity for Women in Renewable Energy Technology Use in Bangladesh. This was initiated in 1999 with $175,000 from ESMAP as a project in Char Montaz, a coastal island in Bangladesh, with technical assistance from Prokaushali Sangsad Ltd (PSL). South Asia Partnership, Bangladesh, an NGO provided initial support in social mobilization and micro-credit. The project provided skill and renewable energy technology training to 32 poor women in Char Montaz and assited them in establishing the Coastal Women’s Electrification and Development Microenterprise, which now has become a SME with 117 employees.

Diversification: Initially, it was assembling of DC lamps and providing services through battery charging station. Now the SME has moved to assembling CFL and LED lamps, controllers and inverters of solar home system (SHS) and mobile phone chargers. It has provided SHS to almost 30,000 households, small enterprises and markets in coastal areas, where grid electrification is not a feasible option.

The lessons from this project was taken into a larger project: Bangladesh Rural Electrification and Renewable Energy Development ($200m). In this project, nearly 200,000 SHS are provided to poor households in remote areas. Grameen Shaki, Srijani, TMSS and other NGOs learnt from this project and made micro-finance available to the poor households for SHS.
