There are 522 pages of unclassified DARPA projects for 2010-2011. This is a second look at more of the projects.

The first look at DARPA 2010-2011 projects is here

Transformer (TX) Vehicle AKA flying car
($12 million) The Transformer (TX) Vehicle program will examine the feasibility and approaches for developing vertical take-off and landing, road-worthy vehicles that carry a 4-person payload >250 NM on one tank of fuel, can safely travel on roads, and can be operated by a typical soldier.

FY 2010 Plans:
- Conduct trade studies of vehicle designs, lift motors, flight dynamics and control, energy conversion
and storage, vehicle architectures, and concepts of operation.

JOULE AKA Ten times Higher Density Batteries
($4 million) The JOULE program will exploit new architectures, reversible electrode structures, materials, and chemistries for the development of rechargeable, high energy density batteries that match or exceed

increase the power density of these batteries. The program will develop new chemistries for positive electrodes to demonstrate reversibility in the graphite fluorite (a high-voltage, high-capacity material) class of positive electrode materials in reversible batteries for the first time. The energy density will increase over ten-fold current lithium ion batteries commonly in use.

FY 2011 Base Plans:
- Investigate chemistry and materials to enable rechargeable high energy density batteries.
