Solar plane grounded by heat damage

A solar-powered plane has been grounded by damaged batteries for at least a few weeks after completing its record-breaking five-day journey from Japan to Hawaii.

The Solar Impulse 2's team said the batteries were over-insulated and became overheated on day one of the Japan-Hawaii leg.

The team said today that it had monitored the situation throughout the flight but could not decrease the temperature.

The plane will not fly before the beginning of August as the team works to replace and repair damaged parts.

The plane landed in Hawaii on July 3 after completing a 118-hour voyage which broke the record for the world's longest non-stop solo flight.

The Solar Impulse 2 is next headed to Phoenix as part of an around-the-world flight meant to highlight the importance of renewable energy.
