EVF PROMOTES TECHNOLOGY TO SOLVE ENVIRONMENTAL ISSUES.
Japan’s latest technologies to cope with environmental issues are ranked
highest in the world. Conventional technologies accumulated over long periods
of time are still considered precious assets. Environmental Veterans’ Firms
(EVF) aim is to establish a Non-profit Organization, namely a public corporation,
to solve various environmental issues sensibly and in a low cost approach.
To go forward the activity, retired scientists and engineers will be engaged
using their vast and profound experiences cultivated during their days
in commission.

Honda quits continuing Accord hybrid for the next model year
2007/06/23
-
They quit hybrid in 08 MY Accord. To limit hybrid for Civic and the new sub compact brand, they will use diesel for larger vehicles such as Accord. Defer from Toyota, they set diesel as main stream technology for environment
-
Toyota postponed 09MY Prius hybrid
2007/06/19
-
Because of the change of the hybrid system based on Li-ion battery, the development and the production for NMH battery may take additional half a year. They will start to sell it from spring of 2009.
- TORAY demonstrated DMFC which is using hydrocarbon electrolyte membrane.2006/02/27
- The feature of TORAY’s electrolyte membrane is that sulfone group combine
monomer and then polymerized. At the same proton conduction level, permeability
of methanol was reduced by under 1/10, compared to that of fluorine
system”Nafion117”. About durability, degradation is a few % after 2000 hours
working.
- KURARAY developed Electrolyte Membrane with free
halogen 2006/02/06
- Kuraray has developed an electrolyte membrane related to carbon hydride for
methanol fuel cells (DMFC).Compared with conventional fluorine electrolyte
membranes,the newly developed carbon hydride electrolyte membranes reduce
methanol permeability during power generation by 40%,boosting maximum power
output by 1.6 times.

- NORITAKE developed electrolyte membrane, which can
reduce permeability 2006/02/06
- Noritake Co.Limited announced that permeability of methanol can be
suppressed by 1/15 - 1/30,compared with conventional. Using inorganic material
with less stretch as basic structure of membrane can suppress the swelling of
organic electrolyte.
- YAMAHA announced the 06’ year model hybrid bicycle
‘PAS’. 2006/01/26
- YAMAHA increased the amount of NiMH battery of the 06 model to 3.1 Ah.The
battery can be charged by putting it on the charger for 2 hours and its range is
extended to 31km in the normal mode.

- Honda to mass produce thin-film solar cell with
the efficiency 12% from 2007 2005/12/22
- The solar cell that Honda mass produce is the best conversion efficiency of
12% in the thin film type.The consumption energy during the manufacturing
process is half compared with an existing Si solar cell.
